@@MrAntsunator nah if your just not used to drinking (a lot of) water you really don't feel thirsty. As a kid I drank almost nothing and could go a whole day with only going 3 times on the toilet. I needed to force myself to start drinking water and it's still hard for me today.
@@Vnp99 I have no idea. For me it's just better to drink more because it's filling and I don't crave food that much but I don't know if anything changed (like stronger hair, skin or something like that). I just realized that everyone else was drinking so much more than me and they always told me I needed to drink more, so I thought it must be good.
welp, a well-functioning body knows how to signal you what nutrient to consume into your body. I read "You Are What You Ate Six Months Ago" by Aya Murayama and it changed my whole relationship with eating because I had same problem with you that my body don't signal me what to eat nor drink. it might sound nonsense at first but yeah, you should check it out.
That's basically a very succinct way of saying what the doctor was saying. The only reason that you feel thirsty is because you're already in a state of dehydration.
I started to drink about 2 - 3 L when this 8 glasses a day craze started going mainstream. And ever since my lips stopped getting chapped and numerous other noticeable benefits. Sooo... i'm going to keep doing that
That is sensory adaptation in a way and also everyone has different skin types so as long as it's beneficiary and doesn't have any side effects keep goin'😃
And you're sure you haven't made any other changes that can affect the elasticity of your skin? Dietary changes? Exercise? Relocating somewhere with a different climate? New skin care regimen? Etc
@@SohamBhattacharya3105 Well, truth be told my friend, I was breathing with my mouth way more often and consciously started breathing with my nose and that REALLY got rid of chappy lips. But the water definitely helped. I've been drinking it for years, minimum 2 L, so I can't fully say the other benefits because I don't know how it was before.
@@SohamBhattacharya3105 yep, that's a thing. For me, the most obvious signal of dehydration is my lips getting dry. It only takes them a few hours to get chapped.
Your body is not telling you to eat pizza. Your body is telling you that you’re hungry. You make the choice with what you want to eat with your brain. Your body can survive without pizza. However, you need water to survive.
Personally I've been through stages in my life where I've only drunk water when I've felt really thirsty and then when I've made a conscious effort to drink water regularly through out the day and evening I've come to the conclusion I feel alot better ( hands down ) drinking plenty of water rather than waiting to feel thirsty I'm sure a lot of others would agree ....
@@S.Ham1929 bruh, I imagine your dad has palpitations all the time if he only drinks coffee lol. I do drink coffee but I can never make myself drink coffee more than once because I won't be able to sleep at night.
@@SKNayak-gl4xt seems like you're being purposely obtuse. here are some options if you think its so hard to get up for 45 seconds and drink a glass of water a few times a day: get a water bottle, carry it around, take a 5 second sip from it every now and then OR drink 2-3 glasses at every meal time; if you're "so busy" you can't even do that, wake up 5 minutes early and chug those glasses of water
@@SKNayak-gl4xt so you actually were being obtuse... I presented 4 different viable options and your response is “drinking water before or after meals is undesirable” (which doesn’t even make sense unless you’re exclusively talking about your personal preference; according to the mayo clinic “drinking water during or after a meal helps how your body breaks down and processes food (digestion)”)
@@AllFactsNoFeelingswithMsSmith i have clinically diagnosed headaches which are reduced by a significant percentage when i am careful to drink 6C water per day. How you know what my subconscious mind is doing? You are right in saying I want to be healthy, i.e. getting rid of chronic headaches.
@@AllFactsNoFeelingswithMsSmith i agree you can over-hydrate. And the notion that everyone should drink 8 glasses is like saying everyone should eat 3000 calories, irrespective of their height, activity level, physical goals, etc. But we ARE given an official RDA for calories, and for fiber, vitamins and minerals according to our sizes. And the CDC tells us how much exercise to do per week. On what basis does this speaker make the claim that drinking water is the ONE thing our body tells us to do with accuracy?
I was so happy to see all of the comments feeling the same way I did about this. I 100% feel better mentally & physically when I drink a lot of water throughout the day. My skin does look better, my gut health functions better, I sleep better…everything is better!! I’m sure she is way more accredited than I am to speak on this but I strongly disagree.
I do it for mental health. It is not placebo, whenever I have racing thoughts I chug a bunch of water and I feel so much more relaxed. This woman will be proven wrong and proven that she caused harm for "correcting pseudoscience"
It might also be because drinking 8 glasses of water reduces the need for other fluid intakes that are less healthy, like cola, alcohol or energy drinks.
I also think that the 8 glasses help to stop people from over eating and consuming drink high in sugar. It's a gimic to make people healthier and it works. In my own personal experience it makes me crave sugary drinks less and no over eat. It is a big contribution to my overall health.
I wouldn't say it's a gimmick as it's only beneficial on all fronts. A little over 2L makes me feel far better through the day, avoiding needless snacking & helps for filtering in kidneys. Can't see a down side.
Same back then but Now i changed it to more fruit that Contain a lot of water and fiber like pear and banana sometimes manggo, its easy to get because i live in tropical island, it help a lot when craving something sweet, now every sugary drink taste too sweet for me, fruit swap improving my taste buds
@jacobt6412 but he just told you the reason. The water simply makes you crave less junk food and sodas, alcohol. This in turn improves your skin. Not drinking more water, but drinking less sodas and alcohol.
I have a drinking schedule because I feel hungry when thirst, leading to me being overweight in the past. Starting with a drink schedule helped me get to and stay at a healthy weight level
I need a reminder for when I need to drink.. If I don't, I'll forget, and then I get a bladder infection.. Some people do need reminders for everything inclusive when to drink water and there is nothing wrong with that.
@@sassy741321 Well I would have a headache and not notice it before I get a reminder. I need a reminder. Fine for you that you don't. With no reminder I wouldn't drink one glass of water.
The body tells you when you need to drink, but sometimes he cant because something is wrong. Thats why you should listen to your doctor in this cases. And that's exactly what she said
@@simon-qy2xe Guys... I'm not noticing the cues.. I seriously need an app to tell me to drink and then I do notice it. My head goes "Oh yes indeed I aaaaam thirsty". It works for me. It's fine that you don't need it but I do.
I’m glad to see the majority of people trusting their own judgement through results. I too, feel a lot better when I remind myself to drink water at different checkpoints during the day cause honestly if I didn’t I could go 8 hours without water during school and not notice.
Why would we listen to the same medical system who told us there were zero side effects from the vaccine, without having any evidence shown to them, except a “ trust me bro”from the WHO and phizer? She also fails hard, when explaining that athletes do need that level of hydration. Basically, your circumstances are so drastically different. You cannot just drink when you’re thirsty.
She has made the point, btw. "So as long as you're listening to your body's internal sense of thirst......" --> This is something that I think a problem for many people nowadays. The lower "sensitivity" of our own body, especially when we get so busy with work we forget to hydrate ourselves. Many of my friends are already habituated for not feeling thirsty after eating they don't feel it's necessary to hydrate themselves with at least pure water (not water from the food they take). Then they develop these kidney stones or some even had kidney failure. The doctor kept saying "Your kidney has worked too hard. You might have not hydrate yourself enough regularly and that might be the cause of it."
indeed. also, if you have conditions like insuline resistance, you mistake thirst for hunger. and eat instead of drinking. What she says in the video is only true if 1. you are healthy 2. you don't exercise regularly. weight training, building muscle requires more fluids. My joints hurt if I don't drink enough water.
Thirst and hunger are two so fundamental things we feel and it has kept us alive for thousands of years. The idea that busy work or lacking sensitivity of our own bodies is quite ridiculous. We have been busy to keep ourselves alive for our whole existence. Of course we’ll still feel thirsty when we need more water how would those signals go away?
@@John_oR. Not sure why. My guess is body sensitivity (or what I myself usually call "body alarm") is very connected to the dynamic of hormones, which can be influenced by the things we do, experienced, and even things that are being thought about. Somehow people who claim themselves or seem to be "stressful" around me tend to forget to hydrate themselves. Heck, they can even forget to breathe! It's ironic to think how a human's busy life challenges the existence of things that make a human human. Food for a thought, indeed.
@@John_oR. it's not ridiculous since today people are bombarded with numerous assignments and tasks every day. you can easily forget to eat/drink due to insane multitasking coupled with high stress.
i agree that we have a lower sensitivity since we are in the age of the internet and browsing online or playing games distract us and we forget to drink water but there are times where im like "I NEED WATER" just like that one spongebob episode and we get desperate for it suddenly
@@dianahill3384 It would be better information if she said 2 litres, never once mentions how big those "glasses" are. Although using metric does confuse some US Americans,and Probably those that think a Big Gulp is a glass of soda.
@@lindatisue733 Most Americans consider a glass to be 8oz. So 8x8 is 64 ounces. Anyways the reason the defined 8 glasses a day is beyond stupid is it doesn’t account for the person’s size or caloric intake. If you’re 250lbs you’ll prob want 10 glasses. If you’re 150lbs you prob are fine at 5. And again that would change with calories and amount of exercise too. 8 glasses a day is as stupid as BMI charts
In hot weather it's easy getting dehydrated without noticing, better to drink water proactively than waiting for warnings from your body. Also the colour of your pee can tell you a lot, so if your pee is completely translucent (water like) for multiple days, than you might be drinking too much water, but as long as it's yellow, or better jet light yellow, you should be fine.
03:46 “or are elderly” She should have put more emphasis on that! Thousands of elderly (and some not so elderly!) people get taken to hospital every year because they collapse while shopping or walking around town because they forgot to drink. Maybe 8 glasses are too much, but please don’t rely on your body giving you an alarm signal, because that doesn’t always work like it should!
thirsty isn't an alarm signal its just a sign, alarm is when you are REALLY thirsty. but yeah it might have been better to put a bit more emphasis on that
As we get older our thirst mechanism decreases. This is why the elderly are more susceptible. Plus some take more medications, have more medical conditions which all contribute to dehydration
Kidney stones are painful. My Mom had them and can create vomiting. She never drank enough water; supposedly stone are hereditary, too. Malarkey? No one else got stones.
Literally have heard from Physicians, nutritionists, nurses, exercise physiologists. A lot of different people in different disciplines explain that if you wait to drink until you’re thirsty you’re already dehydrated. That’s why you’re thirsty now, your body needed water 30 minutes ago. Obviously she’s a doctor, but I’m gonna continue to drink my gallon a day. Even if its not proven to help people in general. I definitely notice a different between properly hydrated me, and “drink when I’m thirsty” me.
@@valmiro4164 you can die by over drinking. It takes a lot, and very quickly, relatively to your body mass. It’s very hard to do. Drinking when you’re thirsty is still, years later, not optimal. By that time, it’s already too late. But also, no you should not drink too much water in preparation for something. Just be hydrated.
@@valmiro4164 it’s really not that common, no. It can happen, of course, and of course athletes, mostly in high school do this, but it’s very hard to do actually. Much more common, and a much larger issues in general is dehydration which leads to dehydration sickness, as well as flairs up many more underlying issues, and depending on the temps can also cause more serious issues like heat stroke. Again, if you wait to drink until you’re already thirsty, you’re already dehydrated. Overdrinking can happen, but it’s very hard to do, and no where near as common as dehydration.
I live in hot environment, and I rarely get thirsty, like if I was born without the thirst option.. of course I collapsed a month ago due to dehydration
Bro same. I live in Canada so it’s not nearly as hot but it’s dry, and even when it does get hot my thirst signal is so slight that I completely ignore it 😬
I’ve had multiple holidays to warmer climates where during an excursion someone in their 20’s (different people) collapsed because they didn’t drink enough. Once a girl needed to go to the hospital for it. if the risk is that people need to go to the toilet for drinking too much, I’d rather have them think that, than that they think they should “listen to their body” when they are warned to hydrate. People are stupid, so they’d better make the safe mistake
I think she's probably right in that you don't need 8 glasses a day. But you don't need to wait until you feel thirsty either. Just drink water throughout the day. I do feel better when hydrated, but I have in the past overhydrated myself while I was sick, drank too much water after throwing up and it made my salt level too low (a Nephrologist told me so in the hospital, I had to eat more to get my salt levels up). I think it's really a case-by-case basis, as everyone's body chemistry is different and probably requires different amounts of water to function at an optimal level. Sort of like how it's healthy when/how long we sleep based on each person. Doctors online give the basics, but it's up to us to take that advice and figure out what works best for us. Maybe discuss it with your own doctor.
You can increase the likelihood of getting kidney stones if you don’t drink enough water but also if you drink to much. If you just drink when you are thirsty and it comes out correctly on the other end you are good. No need to over due it or anything.
I know this is rare, but I know people who adapt to thirst. They simply don't drink. The worst I saw was my roommate in boarding school, he felt sick and could barely move. He was sent to a hospital and the doctor said that he was severely dehydrated. The other one is my cousin, he had to set alarms on when he should drink. He could felt thirst, but he forgot to drink. Silly, right? But this is real.
Some people have the feeling of thirst very similar to a feeling of hunger, so they eat rather than drink, which placates the body temporarily until the feelings return.
@@cattysplat so true! And I think that thesw cues are even more confusing to people in food deserts, people experiencing poverty, or those in information deserts. It’s safer to give a ballpark answer than simply say “your body will tell” because that assumes you know how to listen to it or even that it’s functioning correctly.
the 8 glasses is a guesswork since the collective wisdom thinks "oh the body is XX% water and you need X% of you bodyweight in water" the math for the average person ends being 8 glasses but that concept is outdated, because it dont consider water retention and water from food people forget that glucose = water, the first thing that happens to the body when you stop eating carbohydrates is you get a lot of dehydration
I think one thing she missed : always have water by you so you can drink when you feel you need to. I agree 8 glasses or a gallon is too much, I tried it and it disrupted my day so much going to the bathroom 10 times during the workday. Then I looked up the facts, and realized I was doing more harm than good by being overly hydrated.
I know your comment is a year old, this is for anyone else stumbling on this video. Your body will adjust to higher (proper) volumes of water consumption. After a week, the frequency of your bathroom breaks will return to normal (your body needs time to adjust and properly hydrate your skin/organs/muscles). A good rule of thumb is if your urine isn't almost clear, you need to be drinking more water. 1 gallon a day is not going to cause any harm, and is actually insufficient for many people who regularly sweat (athletes, those who work outside in the summer, etc.).
@@GameOn0827 This is important. Over hydration harm is only in those who chug water to an extreme and your body will angrily tell you to stop drinking. Your body weight, height & level of exercise matters to how much you drink. When I was training for a marathon it was 3L+ of water. Now sitting around working on my computer it's down to ~2L+ and I haven't suffered a heat stroke or bad over-hydration in my life. A important thing is to listen to your body, but more often than not it's late to telling you dehydration being the best example. It's better to increase your amount of water finding a suitable amount depending on yourself then sticking to it.
Well kidney stones can be caused by eating to much sugar/carbs which causes insuline to rise which causes kidney function to be diminished so that it cannot always correctly get rid of all the salts. Fix your carb intake, lower your blood sugar, which will eventually lower your insuline level, which enables your kidneys to recover and keep the correct salt level in your blood. Also eat less of the legumes and vegetables that are high in oxalic acid because oxalates easily crystalize in cells or on kidney stones or gall bladder stones. Eat the vegetables or legumes that are low in oxalates. Also sugar in your blood means that your blood turns slightly acidic which is dangerous so your body balances that out by retracting calcium and some other salts from your bones to make you blood less acidic. But that increases salt level in your blood which your kidneys would want to get rid of but has an issue with so the kidney stones grow. Also it causes osteoporosis eg weak bones because they slowly deplete of calcium and magnesium and some other salts. FYI: osteoporosis is also called diabetes type 3 and alzheimer is called diabetes type 4.
@@RachelMurrdererWolf Mine were caused by the amount of magnesium I used to eat. Other people I know were caused by calcium. No amount of water will change getting a kidney stone, just might make it pass slightly quicker. Assuming it doesn't get stuck like mine did, requiring a Stent.
@@beepboop9464 This is not true at all. Most kidney stones are formed when supersaturation takes place. That will only happen if you dont drink enough water or have some other health related issues. If you always pee yellow-ish clear pee theres no way for the amount of calcium, oxalate, or phosphate you need for kidney stones to be able to accumilate
RUclips comments (as usual) missing the point, giving random personal anecdotes. The point of the video is that 8 glasses a day is not a hard rule and is somewhat arbitrary, and that you can maintain healthy hydration without succumbing to overly generalized pseudoscience statement (given that excess hydration doesn't scale in terms of health benefits). Understand your body has its own tools it uses, and by understanding that you can assist it to make sure everything is gucci.
while i like the myth-busting approach in this video, i think its too short and ignores to benefit of drinking water. because most of the people who need rules like "8 glasses a day" nearly never drink water so things like: not drinking your calories, helping with digestion, making you feel full, etc. should be mentioned. psa's are great, but this one is too simplified and might lead to further misunderstandings
So you think we need nonsense like 'drink 8 glasses a day' because the science of 'drink when you're thirsty' is too complicated a message? Riiiiiiiiight
@@MrJKJKJK1974 not everyone listens to their body tho, some needs to be pushed to do what they need to do. plus, what if im hungry all the time, so should i listen to my body and just eat every minute
@@MrJKJKJK1974 yes. My body often not giving thirsty signal properly (and I believe I'm not the only one like this). I can 'forget' drinking water a whole day if I'm busy. 8 glass of water is a good standard for me because it's easy to count.
I had kidney stones (it helped me find i had a cyst, but anyway), trust me you dont want them... the answer to that is stay hydrated. This video is bugging me, why would you argue with ingesting more water ?? there is no such thing as too much water (except in extreme cases). the important thing is to drink whenever you are thirsty (even just a little), and add a few random occasions to drink. Stay hydrated, stay healthy. Drink when you are thirsty, and a little more. and avoid these fu.... stones
Well, there IS such a thing as too much water, but it would take way more than 8 glasses of water all at the same time. 8 glasses of water spread throughout the day is fine.
@@warlord-chan9540 It's more like the minerals in your body are diluted too much by excess water. Without the excess water, the minerals could have been sufficient. It's about the concentration of minerals, which changes with the amount of water.
Exactly! I was 11 when I had my kidney stone, and as a kid I was too busy at school to drink that I just didn't, missed all the warning signs of 'thirst' and volia, kidney got removed along with the stone, and now when people say they haven't drank any water that is a really serious & personal matter!! Please stay hydrated people!!
I work in the military, and train physically 2-5 hours a day. In summer heat I often end up drinking over 4 litres in a day. Cause my body is telling me to.
I literally had tachycardia, fainted multiple times, and looked like I was on drugs just because I was dehydrated. And I was drinking water, I thought I was drinking enough of it but I never realized that I wasn’t drinking enough until I was in the back of an ambulance!
@@danielberei3021 I feel the need to add that salt also dehydrates you!!! yeah we need salt but don't go eating more salt because this comment told you it will help you stay hydrated, you can die from eating too much salt so fast, it's a really painful death.
@@ActuallyLemonshave you got any proof evidence or study that anyone died because of salt overdose? You haven't done it because you are still alive, right? So, why are you talking nonsense. Yes, it is clear that you can go I'll from everything, even something that is healthy. But in the case of salt you have a set of organs that protects your body from low salt intake and even overdose. Those organs are your kidneys. Bet you are a kid too and only live on packaged so called "fooda" and vegetables like pizza
@@ActuallyLemons As a kid running a ton I consumed too much salt at one point before a big race. By the end I sweated out so much of it-it visibly crystalized on my skin more than I had ever seen. If you don't drink plenty of water/exercise and consume tons of salt you'll for sure be bringing yourself to an early grave.
Hi everyone, I know I'm gonna get some lashing and heat for this but over the years I've realized that no one else really lives the way I do and always wondered why people drink and eat the way they do. So here it goes. I don't drink water at all. I get it in the form of foods. I eat once every other day. I run 20 miles a day. I am 44 years old and I am super healthy. I'm 5'10". 170 lbs and ripped. I do not drink alcohol, smoke, or even take aspirin. I know that this.all sounds ridiculous and idiotic, because tbh no one else I know lives like this. I do truly believe you have to listen to your body, and not believe every single thing someone else is telling you to do with your body. I've lived like this since I was a child. Never drank milk ever in my life.either. I'm extremely active and no one my age can keep up with me, and hardly anyone in there 20s for that matter can either. That is not me bragging but the honest truth. I know I'm an anomaly but this is my life experience and I am not telling anyone or suggesting anyone to live like this, I am simply sharing my life with you.
its when a start to have a headache and eye fatigue that i know that i am dehydrated. Sadly, its take a whole hour after drinking for the headache to leave. getting into the habit of taking a sip every hour is clearly a good thing...
Definitely. If one would always wait until the body *needs* water, headaches would eat your alive sometime. Even if apparently it’s not necessary to drink 2 liters a day, the habit of drinking a sip every hour is really a good thing if you want to avoid headaches or other pains.
Another key thing to note is that medications can influence how much water you need as well. People on lithium - a salt - need to stay very hydrated in order not to get lithium poisoning.
Yea, but if you're on a medication like that, generally your doctor is going to inform you of that and let you know that you need to drink more water because of that medication. That doesnt really apply to people with normal functioning bodies though who arent on medications. If you have a specific reason why you need to drink more water, then your doctor is usually going to inform you of that, and in that case, yea, listen to your doctor. Otherwise, paying attention to your bodily signals and drinking when you feel thirsty is good enough for anyone with a normal functioning body.
Glad I read the comments--- I'm one of those that drinks a ton of water each day, especially when I first wake up. I feel like it cleanses me internally and it definitely has done wonders for my skin as opposed to when I drank significantly less. I know when I'm dehydrated when I'm dizzy and about to pass out which has happened once, maybe twice in life-- I otherwise don't know what thirst feels like per-say, but I love consuming beverages. I sun agree with her take on water.
Imho, there's a slight flaw with Dr. Jen's advice, in practice-many people in modern societies confuse thirst with hunger, so just "listening to your body," to paraphrase, won't work well for many people.
That's true! Usually, when youre hungry you just need to drink. If after drinking the hunger is still there, that means you want to eat :D It works for me
This was the case with my girlfriend of some years ago. She drank so little water but ate to full and nausea as a very small person, that one day she called me in some distress to say her urine was clear. She had never had clear urine. I have a good water habit, so when she picked that up from me, the change was stark!
Nice Urban Myth / Wive's Tale :) Show me the science behind your claim :) Please stop posting online if you're not going to have legitimate and valid ideas :)
Who would confuse hunger and thirst? And why only in "modern societies"? Still, if your body needs water and you eat, your body will pick the water from the food
tell this to literally all of my neurodivergent friends who struggle to interpret "internal messages". Nice idea if it works for you but some of us really need a guideline
I was looking for this comment! As someone who is self diagnosed ADHD (still waiting on a referral from 3 years ago) I struggle with interception, and this means I'm often going 3/4 of the day on a morning coffee and a glass of pop (for hydration). The days where I "drink when I'm thirsty" are the days my ADHD is at its absolute worst, and I get horrific headaches and feel generally terrible. This video is quite worrying as I feel like it's based exclusively on theory, and based on a neurotypical, able bodied person. The variables here are so massive that I think the best catch all advice HAS to be to drink regularly
@@MrAntsunator not at all. Just someone who’s been faithfully drinking a gallon a day for since I have 15(Soon to be 33) and just speaking from experience.
I love reading how defensive everyone is getting of their 8 glasses a day. Just because it seemed a simple fix, doesn't make it right. If people only ate when they were hungry they would probably be healthier. Other than those with dementia or other memory/thought function impairments, people remember to drink. If you remember to eat, you will remember to drink. You may fail to do both if busy, but not to the point that harm will happen. Her point is that an arbitrary rule, followed blindly is not good science. And it puts the control of your body into the hands of the people who make those types of rules, regardless of the science or nuances of your own needs. If you exercise hard, 8 glasses wont be nearly enough. If you have small glasses in your house, you may need more. Think about what would show you that you are drinking enough eg the colour of your pee and how you feel.
I regularly confuse the signal for thirst with the signal for hunger. The implication that your body has a flawless method of informing you how much water you need is almost certainly more harmful than advocating people drink 8 glasses a day.
My body tells me I need water when it's too late. I always have a water bottle near me within my peripheral vision so that I drink water often. Despite what this lady says, I felt healthy and my skin health visibly improved. If I fail to drink alteast 8 glasses of water a day I feel like a zombie(sick and sloppy/tired). This applied to my parents and friends too. So I suggest you guys to take this vid with a grain of salt.
Probably placebo. 8 glasses a day is a completely arbitrary amount with no scientific backing. If you are needing EXACTLY 8 glasses a day to feel good, its almost definitely because you are victim to the placebo effect. You only get 7 glasses, realize you didnt get 8, think you're going to be sick and dehydrated cuz of it, and then do feel that way because you think you will. For the vast majority of people, 8 glasses of water is way more than they actually need. So if you drink like 6 or 7 glasses, you shouldnt really be feeling any of the effects of dehydration. The fact that you DO very strongly indicates that its just the placebo effect. One thing that you can do to actually check, is check your pee. If your pee is mostly clear or slightly cloudy (as in a light yellow), then that means you're not dehydrated. However, if your pee is a darker yellow or orange, then that means you probably are dehydrated. That is a much better indicator of how dehydrated you are. So if you have normal looking pee, but you still feel dehydrated, its probably just the placebo. If you do have darker colored pee when you only drink like 6-7 glasses a day, then you might be one of the few people who actually needs that much water in a day. But the vast majority of people do NOT need to drink that much water in a day. Unless your body is losing a ton of water through other means, you dont need that much.
I’m not waiting for a thirstiness.minimum 2liters of water in a day and I’m feeling very refreshed .know what my organism needs and how good it’s for my inner and outer hygiene.
I feel like I can't completely count on my body to let me know when to drink. I do feel clearer-headed and energized when I consciously add extra glasses in throughout the day.
Sorry to contradict, but it does improve my skin, and it makes me clearer headed and more alert too. I only upped my intake to help my skin, i didnt know about other potential benefits, so it isnt placebo.
@@knucklesamidge Because i had no awareness that becoming more alert/clear headed was a possible result of drinking water. I'd never heard or read that before. I'm also a skeptical person, so the first time it happened i didnt conclude that it must be the water alone, but it happens whenever i drink 2-3 glasses in quick succession. The time of day doesnt seem to make a difference either. Re my skin, it does seem to contribute to clearer and healthier looking skin, but i acknowledge i had the expectation of this result.
@@danielong9170 I have a tendency towards cystitis so I've been conscientious of that for decades. I had a really bad episode of cystitis on a trip to Euro Disney when I was 13, and then another extreme one in my early 20's where I ended up at the doctor's, so I'm quite careful in that regard. I started upping my water in my mid 30's, that's when I noticed the effects.
I experienced, when i have something to drink around me, that i do drink more. It's already a habit for me to grab my drink if i just feel my mouth drying. I think i wouldn't do it if i wouldn't have something to drink around me. You are mostly fine, but helping your body by having something to drink readily around you makes, at least for me, a lot of sense. Still, thanks for this video. Mostly it's not too good, to try too hard.
Your body will NOT always tell you it needs water. She just dismisses it in passing "unless you've(sic) kidney stones or elderly". Three guesses how those kidney stones happened in the first place..
@@FeplayBuilds But how do you know how much you need? That's why people fling around "8 glasses a day", because people genuinely don't know and simply saying "your body will tell you" does nothing whatsoever to address the problem.
@@HippopotamusPencil man you get thirsty when you need water! and for the people who don't only they or elderly people need to check their water intake and they should consult doctors instead of reading blogs which will only say 8 glasses even though everyone needs a different amount!
@@FeplayBuilds Yes, the amount is different for everyone, but GENERALLY, 8 glasses a day is RECOMMENDED. We know health science is different for everyone
I wish my body told me I was thirsty! For years I've been drinking less than 16oz a day because I'd have to pee all the time if I had more. My doctor told me constant headaches and difficulty focusing could be signs I'm not drinking enough. For 4 days now I've been following the 8x8 rule and my headaches are better- I've also noticed my skin isn't as dry and my acne is reduced. I'm going to continue and keep monitoring how I feel.
That is just a guideline that hasn't been validated by science. It is just a nice guideline. Doesn't mean it is wrong, but a lot more variation then that guideline is also probably right. Kidney stones can also be caused by eating to much sugar/carbs which causes insuline to rise which causes kidney function to be diminished so that it cannot always correctly get rid of all the salts. Fix your carb intake, lower your blood sugar, which will eventually lower your insuline level, which enables your kidneys to recover and keep the correct salt level in your blood. Also eat less of the legumes and vegetables that are high in oxalic acid because oxalates easily crystalize in cells or on kidney stones or gall bladder stones. Eat the vegetables or legumes that are low in oxalates. Your urologist should know these things if he is up to date with the science. Also sugar in your blood means that your blood turns slightly acidic which is dangerous so your body balances that out by retracting calcium and some other salts from your bones to make you blood less acidic. But that increases salt level in your blood which your kidneys would want to get rid of but has an issue with so the kidney stones grow. Also it causes osteoporosis, eg weak bones, because they slowly deplete of calcium and magnesium and some other salts. FYI: osteoporosis is also called diabetes type 3 and alzheimer is called diabetes type 4.
I need between 2.2-6 liters of water a day, which is more than 8 glasses, so I certainly fall into the 8 glasses *plus* a day category. You'll drink when you're thirsty *if* you have water available. I always keep a full mug of 20oz water on my desk, and I reach for it subconsciously. Always keep water available and you'll probably develop a better connection to your thirst gauge!
I always have a waterbottle by my desk and I don't really instinctively reach for it unless I'm on a video call, then I have this weird nervous habit of constantly taking sips from my bottle haha
well yea, if you're actually thirsty and legitimately drinking that much water, thats different. Some people do drink a lot. But the point is that everyone's bodies are vastly different, and the 8 glasses a day thing is COMPLETELY arbitrary. It has no scientific backing whatsoever. Some people need more than that, and some people need wayyyyyyyy less. It really just depends on your specific body. So the whole point is that you shouldnt listen to the "8 glasses a day" thing. Instead, you should drink when you feel thirsty. That way you give your body how much water it actually needs. If that does lead you to drinking more than 8 glasses a day, thats perfectly fine as long as you were actually thirsty for that water and werent just forcing yourself to drink more water. But in general, most people are not going to need 8 glasses a day.
This seems to be condensed video version/a video summary of her podcast. It is linked in the description. On there she talks with experts about these topics, in this case a nephrologist. So here info comes right from the source. But even without the podcast, these kind of TED-Talks don't have to be written by the presenter. There could have been an expert at least reading the script over behind the scenes. To be fair though, TED should have been clearer about the creators/background of this video.
Ya, we often get most of our water from the food we eat on most days. Also, a slight dehydration can feel more like hunger, its often helpful to drink a small amount first when feeling hungry as light thirst can be confused for hunger and cause unwanted over eating.
Really funny how she completely ignores the fact that her entire argument is based on people listening to their body, when in reality people can go without food without noticing it for literal days because we live in a society with next to no downtime, a lot of stress a lot of distractions. And in the flow state you don't really notice much of anything outside of your tunnelvision. You don't need to drink half the ocean everyday but you gotta set time aside to listen to what your body actually needs.
"Really funny how she completely ignores the fact that her entire argument is based on people listening to their body" Huh? Perhaps you missed it, but that's the EXACT POINT she's making - don't just mindlessly drink, only listen to your body.
it’s actually good to go without food for 12 hours, 24 hours or longer. People with 28% body fat can literal fast for days without a problem because the body is made to handle long periods without food. There are doctors who have helped thousands of people reverse type 2 diabetes, arthritis etc. But the same doctor you see will prescribe you insulin because that’s what they’ve been told to do..
The problem is that many don't know what "dehydration" means. If you're thirsty, you're thirsty. If you're dehydrated the body is really lacking water. Saying you're dehydrated because you're thirsty would be like saying a slight feeling of hunger means serious starvation. It's a gradient.
Yea, the saying of "if you're thirsty, you're already dehydrated" is so dumb. When you're thirsty, your body needs water and its telling you that. But you arent in a SEVERE need of it. Just like you compared with hunger. When your hungry, your body needs food, but its not a severe need like starvation. If you drink when you're thirsty, then youll never have any negative effects from not having enough water. Thats the ultimate point. You dont need to preemptively drink just to avoid going below 100% satisfaction of water at all times. Needing a little bit of water isnt going to hurt you as long as you actually drink water when you need it and you do feel thirsty.
Important to note how drinking alcohol and caffeine excessively leads to dehydration which leads to other problems. For many people they don't see this as logical, because I am drinking liquid so I should be hydrated. A habit of drinking large amounts of caffeine and alcohol everyday will inevitably have consequences, that's where this crazy advice I believe came from, so people could continue their excessive habits and try to compensate with silly amounts of water consumption.
Speaking from someone who has lost a kidney due to kidney stones and dehydration, you SHOULD drink water as your body can easily be ignored accidentally (especially if you are a child in classes or glued to the TV) when it is asking you to drink water. Stay hydrated please!!
Since the age of 15 I’ve always enjoyed drinking water. I do suffer from kidney stones which is very painful but I imagine if I didn’t drink as much as I do it would be extreme
These video is a collection of right scientifical facts that bring to wrong conclusions. If you are not used to drink water, you will have a lot of retention and you will hardly ever feel thirsty. But that does NOT mean that you should not drink more.
Yeah I'm not really buying it that our bodies will tell us without fail when it's thirsty, or that we're not already slightly dehydrated by that point which most doctors say to try to avoid. I tried listening to my body with food for the first 20 years of my life, and it didn't work out for me. As a kid, I remember being in the 80th percentile for height but 5th percentile for weight. I ended up needing to be hospitalized because I was so sick from inadequate calories... turns out that my body doesn't know when it's hungry and I need to be on a med to stimulate my appetite. It's considerably easier to eat now, and I've gained 40 pounds so that I'm finally at a healthy weight. I imagine some people experience the same thing with water, especially if they're stressed or super busy.
Yeah exactly. 8 glasses of water a day is itself not an clear measure, we must drink 3-4 litres of water a day. Specially in summer, the more the better.
Ok so I work as an carpenter and sweat like 2 Liters a day but don't feel any thirst. I almost Collapsed because I forgot to drink, and you want to tell me that this is normal? I have to force myself to drink or i probably just die. But ok
It’s anecdotal, I know, but the $1000 ER bill for a child who forgot to drink tells me we should probably be checking the color of our urine, and have a basic water consumption goal regardless of how god our bodies’ signals are
Super misleading video. Basically asks you throw out all the education from sport and physical science. If you're body is at the point where the urine is concentrated (super yellow) like she talks about, your muscles will already be fatigued and facing cramps. The thirst response is a sign you are dehydrated and it takes at least 45 minutes for any water you drink to show it is rehydrating. By that point your body will already be broken down or you could just pass out, unless you stop and cool down entirely. So maybe you don't need 8 glasses a day if you live a sedentary lifestyle, so for the average person, not a big deal. For kids and athletes trying to learn how to prepare for anything strenuous this video is not just misleading, but borderline dangerous. Lots of kids, adults and elderly folks die or go to the hospital every year from heat stroke (hand in hand with hydration) and severe dehydration. PSAs are good, but discouraging folks to hydrate themselves feels dumb.
Yup my son collapsed on the treck circle and EMS was called for heat stroke ☹. Hadn't drank anything but pushed to run in 100° heat. I was sups angry and freaked.
You can drink more and eat more out of habit, you'll feel hungrier a few days after those BIG meals because you've dilated a bit of your stomach volume and that sense of fullness isn't the same
Water is important always carry some with you and drink through out the day. I watched a terrible news a wrestling boy died from dehydration because his coaches refuse to let him drink water until he finished training. At the end they lied and told to give him water and told him to go find yourself. Every doors were locked that day even fountains were emptied. He died and his peers were pressured to not help and watch him run for water.
As a person that usually drinks tea just out of boredom while studying (so I drink more like 4L a day) I can tell, that when I go to work on my car, and it takes me say, from 8 am to 10pm, there is a good chance that I won't feel any thirst, because I am actually focused on something. And that's where the 2L a day come in. Just as a number for people who are doing their job and do not feel thirst, hunger, pain... because they are focused. And don't tell me that it's fine then. One day every month, maybe it's fine. But if someone is living that way every day, he'll get kidney stones. (Which are an obvious sign that apparently it is very well possible that people can have too concentrated urine and still not drink.)
Oops, this is the real problem, following your “listen to your body” mantra! Completely agree with you. Another way could be, when we are stressed, our normal body function changes a bit, we might less, or we might eat high, we might need not drink! Then, how can we trust our body signals when we are on stress !!
Having ADHD and PoTS means I can't always tell I'm thirsty or get hyperfocused and my meds for that make me sweat more, but I need to drink 3L (about 12.5 cups or 100 fl. oz) minimum in a day to keep my heart rate stable and to feel alright so I'm not sure it's wise to tell people to rely on their body signals - people don't necessarily know they have ADHD and therefore can't drink consistently without reminders or conscious effort, nor do they realise they have PoTS, so without the idea of 8 cups a day in their minds may be chronically under hydrated and suffer quite bad consequences of this 🤨. I know I got very bad with heart rate spikes and fatigue because it never occurred to me that even what seemed a normal amount of water and salt isn't enough until my Dr told me to increase them after I'd been struggling for years 😂
ADHD'er here. I completely agree. I drink 3 litres every day, and it helps me cope with common side effects of ADHD medication, like headaches or heart palpitations.
Overhydration can lead to water intoxication. This occurs when the amount of salt and other electrolytes in your body become too diluted. Hyponatremia is a condition in which sodium (salt) levels become dangerously low.
I stopped trying to drink so much water after watching this video, and I got really constipated. You don’t need to drink eight glasses per day, but you still need to make sure you are drinking enough to keep your bowels moving!
I get olympic-grade cramps in my abdomen, legs, and shoulders when I move in whatever my body decides is the wrong direction at that moment. They are debilitating and can last from seconds to up to 20 minutes. I'm never thirsty when it happens but getting to and chugging a bottle of water will fix it in a half hour. It happens more often during a week when I am doing a lot of physical labor but doesn't cramp at the same time as the physical labor (usually, not exclusively). I disagree with your assessment of just listen to when your body says to drink water. I don't drink soda or juice and sometimes have a small coffee in the morning. I don't know if the fact that I almost exclusively drink water (because I literally live in a desert) has anything to do with that but thought I'd mention it. The cramping got much worse when I hit 35-ish. I went to my dr about it when it was just leg cramps in the night years ago, but he said there was nothing wrong with me and I just had to deal with it.
What a jerk. Maybe find another doctor. They don't generally consider nutrition. Allopathic medicine is about drugs and surgery. I picked my doctor talking to a pharmacist. Best choice I ever made for my situation. Plus she is hip on nutrition.
People always say: drink only if you feel thirsty. It's comical. What if a person's lifestyle is drinking alot of tea and liquid carb to soothe thirst. These people often don't like drinking water. I personally think it's much better to reinforce 8 glasses than no numbers at all. So we have a measurable understanding of how much we must consume to be healthy. Because if you actually start to drink proper amounts of water. You wouldn't even count if you reached 8.
I think this applies to perfectly healthy people, which, is like 10% of people. Most people are shoveling dry, processed food, caffeine, sugar, alcohol, supplements, medications, excessive salt, recreational drugs, nicotine, and who knows what else down their throats, drying their bodies up, dulling the internal mechanisms that signal true thirst. The confidence she's speaking with is kind of repulsive. I've heard hydration explained every which way by doctors, nobody ever agrees across the board on hardly anything.
I once realized, when it was 9p:m , that I haven’t drunk a single drop of water since the day before, same hour, and I wasn’t even thirsty. Sometimes you can’t trust your body and you just have to take actions.
I live near the equator and I don't monitor my water intake but I'm sure I don't drink 8 glasses a day and my urine is a very pale yellow, my kidneys function fine and I'm healthy. What she says is true for many people.
I live a healthy lifestyle. I only drink water when “facing real dehydration” and am forced to “do whatever I need to get it”. Just like I only sleep when I physically collapse to the ground due to extreme exhaustion. My body tells me.
Best guess is you either live in a very dry area or you're experiencing the early stages of dehydration and your brain isn't giving off the proper signals.
You adapted to drinking very little. To feel enough thirst for more hydration will now require effort to change your adapted state. I recommend to use bottles and straw's you carry with you. You'll probably start drinking more, simply because it becomes easily available to you and doesn't require to keep the signal in your working memory for a long time. It's just a sip away =)
I can go a whole day without getting thirsty I don't trust my body.
Maybe you aren't doing anything or you get all your water via food.
@@MrAntsunator nah if your just not used to drinking (a lot of) water you really don't feel thirsty. As a kid I drank almost nothing and could go a whole day with only going 3 times on the toilet. I needed to force myself to start drinking water and it's still hard for me today.
Maybe you're actually a cactus... or a succulent 🌵😝
@@hellihello2333 same here... So... Do we need to worry abt it?
@@Vnp99 I have no idea. For me it's just better to drink more because it's filling and I don't crave food that much but I don't know if anything changed (like stronger hair, skin or something like that). I just realized that everyone else was drinking so much more than me and they always told me I needed to drink more, so I thought it must be good.

welp, a well-functioning body knows how to signal you what nutrient to consume into your body. I read "You Are What You Ate Six Months Ago"
by Aya Murayama and it changed my whole relationship with eating because I had same problem with you that my body don't signal me what to eat nor drink. it might sound nonsense at first but yeah, you should check it out.
In the military they taught us "If you feel thirsty, you're already dehydrated".
Good advice.
That's basically a very succinct way of saying what the doctor was saying.
The only reason that you feel thirsty is because you're already in a state of dehydration.
@@niccolom My point was that at that time you already missed a bit of water earlier, which would've prevented the dehydrated response.
I don't think so. Dehydrated sounds a lot more extreme than thirsty
Agree!!
I started to drink about 2 - 3 L when this 8 glasses a day craze started going mainstream. And ever since my lips stopped getting chapped and numerous other noticeable benefits. Sooo... i'm going to keep doing that
That is sensory adaptation in a way and also everyone has different skin types so as long as it's beneficiary and doesn't have any side effects keep goin'😃
@@gauriagnihotri9378 ayy, cheers 🙂

@@SohamBhattacharya3105 Well, truth be told my friend, I was breathing with my mouth way more often and consciously started breathing with my nose and that REALLY got rid of chappy lips. But the water definitely helped. I've been drinking it for years, minimum 2 L, so I can't fully say the other benefits because I don't know how it was before.
@@SohamBhattacharya3105 yep, that's a thing. For me, the most obvious signal of dehydration is my lips getting dry. It only takes them a few hours to get chapped.
"Your body will tell you when you need to drink water"
Well, the same body will tell you to eat pizza at 11 p.m. so,
Or don't sleep at night before school or work xD
well yes but actually no.
Your body is not telling you to eat pizza. Your body is telling you that you’re hungry. You make the choice with what you want to eat with your brain. Your body can survive without pizza. However, you need water to survive.
Sorry, I don't get that message without beer.
Then have the pizza?? I am sure you don't crave it 24/7
Personally I've been through stages in my life where I've only drunk water when I've felt really thirsty and then when I've made a conscious effort to drink water regularly through out the day and evening
I've come to the conclusion I feel alot better ( hands down ) drinking plenty of water rather than waiting to feel thirsty
I'm sure a lot of others would agree ....
Sure do, bud. My dad argues that the only water he needs is from his coffee... then proceeds to complain about headaches and fatigue 🙃😒
@@S.Ham1929 bruh, I imagine your dad has palpitations all the time if he only drinks coffee lol. I do drink coffee but I can never make myself drink coffee more than once because I won't be able to sleep at night.
@@SKNayak-gl4xt seems like you're being purposely obtuse. here are some options if you think its so hard to get up for 45 seconds and drink a glass of water a few times a day: get a water bottle, carry it around, take a 5 second sip from it every now and then OR drink 2-3 glasses at every meal time; if you're "so busy" you can't even do that, wake up 5 minutes early and chug those glasses of water
@@SKNayak-gl4xt so you actually were being obtuse... I presented 4 different viable options and your response is “drinking water before or after meals is undesirable” (which doesn’t even make sense unless you’re exclusively talking about your personal preference; according to the mayo clinic “drinking water during or after a meal helps how your body breaks down and processes food (digestion)”)
@@SKNayak-gl4xt you could’ve just said “yes” instead of wasting my time with this pointless paragraph lol
I get headaches when I don't drink enough water...
Me too... Before i ever get thirsty. This speaker should find different employment.
No you don't. That's what you tell yourself subconsciously to justify your need to drink water when it's really just your need to be "healthy".
@@AllFactsNoFeelingswithMsSmith i have clinically diagnosed headaches which are reduced by a significant percentage when i am careful to drink 6C water per day. How you know what my subconscious mind is doing? You are right in saying I want to be healthy, i.e. getting rid of chronic headaches.
@@EzerEben three liters should be good enough, and is actually on the high side.
@@AllFactsNoFeelingswithMsSmith i agree you can over-hydrate. And the notion that everyone should drink 8 glasses is like saying everyone should eat 3000 calories, irrespective of their height, activity level, physical goals, etc. But we ARE given an official RDA for calories, and for fiber, vitamins and minerals according to our sizes. And the CDC tells us how much exercise to do per week. On what basis does this speaker make the claim that drinking water is the ONE thing our body tells us to do with accuracy?
I was so happy to see all of the comments feeling the same way I did about this. I 100% feel better mentally & physically when I drink a lot of water throughout the day. My skin does look better, my gut health functions better, I sleep better…everything is better!!
I’m sure she is way more accredited than I am to speak on this but I strongly disagree.
Could be partly due to a placebo effect.
yea i dont think she is a very reliable source like sure you dont NEED 8 glasses but that doesnt mean it isnt better i think she's missing the point
I do it for mental health. It is not placebo, whenever I have racing thoughts I chug a bunch of water and I feel so much more relaxed. This woman will be proven wrong and proven that she caused harm for "correcting pseudoscience"
It might also be because drinking 8 glasses of water reduces the need for other fluid intakes that are less healthy, like cola, alcohol or energy drinks.
@@richardkrause9385 that is the definition of a placebo…
"Listen to your body" folks these days don't even know they are cranky due to hunger or lack of sleep.

"these days"? as it that was ever different 😂
I also think that the 8 glasses help to stop people from over eating and consuming drink high in sugar. It's a gimic to make people healthier and it works. In my own personal experience it makes me crave sugary drinks less and no over eat. It is a big contribution to my overall health.
I wouldn't say it's a gimmick as it's only beneficial on all fronts. A little over 2L makes me feel far better through the day, avoiding needless snacking & helps for filtering in kidneys. Can't see a down side.
Same back then but Now i changed it to more fruit that Contain a lot of water and fiber like pear and banana sometimes manggo, its easy to get because i live in tropical island, it help a lot when craving something sweet, now every sugary drink taste too sweet for me, fruit swap improving my taste buds
i just look at the color of my pee to know if i should drink more
@jacobt6412 but he just told you the reason. The water simply makes you crave less junk food and sodas, alcohol. This in turn improves your skin. Not drinking more water, but drinking less sodas and alcohol.

Yes, and how bloody much is "8 glasses?" Is it a shot glass or a tankard?
Haha so true
I have a drinking schedule because I feel hungry when thirst, leading to me being overweight in the past. Starting with a drink schedule helped me get to and stay at a healthy weight level
Oh wow I thought it's just me! I never feel thirsty, only hungry, but this stops when I have some water, so it's like I'm never really hungry?
Me too … I eat when I should be drinking
I need a reminder for when I need to drink.. If I don't, I'll forget, and then I get a bladder infection.. Some people do need reminders for everything inclusive when to drink water and there is nothing wrong with that.
YES! I have a Google thing that literally just shouts "drink" every hour so I remember to! Bladder infections are not nice at all
It’s a little wrong you should pay attention to your body cues (pee color, sweat and other smells)
@@sassy741321 Well I would have a headache and not notice it before I get a reminder. I need a reminder. Fine for you that you don't. With no reminder I wouldn't drink one glass of water.

Thats why you should listen to your doctor in this cases.
And that's exactly what she said
@@simon-qy2xe Guys... I'm not noticing the cues.. I seriously need an app to tell me to drink and then I do notice it. My head goes "Oh yes indeed I aaaaam thirsty". It works for me. It's fine that you don't need it but I do.
I’m glad to see the majority of people trusting their own judgement through results. I too, feel a lot better when I remind myself to drink water at different checkpoints during the day cause honestly if I didn’t I could go 8 hours without water during school and not notice.
Why would we listen to the same medical system who told us there were zero side effects from the vaccine, without having any evidence shown to them, except a “ trust me bro”from the WHO and phizer?
She also fails hard, when explaining that athletes do need that level of hydration.
Basically, your circumstances are so drastically different. You cannot just drink when you’re thirsty.
Could be just placebo
She has made the point, btw. "So as long as you're listening to your body's internal sense of thirst......" --> This is something that I think a problem for many people nowadays. The lower "sensitivity" of our own body, especially when we get so busy with work we forget to hydrate ourselves. Many of my friends are already habituated for not feeling thirsty after eating they don't feel it's necessary to hydrate themselves with at least pure water (not water from the food they take). Then they develop these kidney stones or some even had kidney failure. The doctor kept saying "Your kidney has worked too hard. You might have not hydrate yourself enough regularly and that might be the cause of it."
indeed. also, if you have conditions like insuline resistance, you mistake thirst for hunger. and eat instead of drinking. What she says in the video is only true if 1. you are healthy 2. you don't exercise regularly. weight training, building muscle requires more fluids. My joints hurt if I don't drink enough water.
Thirst and hunger are two so fundamental things we feel and it has kept us alive for thousands of years. The idea that busy work or lacking sensitivity of our own bodies is quite ridiculous. We have been busy to keep ourselves alive for our whole existence. Of course we’ll still feel thirsty when we need more water how would those signals go away?
@@John_oR. Not sure why. My guess is body sensitivity (or what I myself usually call "body alarm") is very connected to the dynamic of hormones, which can be influenced by the things we do, experienced, and even things that are being thought about. Somehow people who claim themselves or seem to be "stressful" around me tend to forget to hydrate themselves. Heck, they can even forget to breathe! It's ironic to think how a human's busy life challenges the existence of things that make a human human. Food for a thought, indeed.
@@John_oR. it's not ridiculous since today people are bombarded with numerous assignments and tasks every day. you can easily forget to eat/drink due to insane multitasking coupled with high stress.
i agree that we have a lower sensitivity since we are in the age of the internet and browsing online or playing games distract us and we forget to drink water but there are times where im like "I NEED WATER" just like that one spongebob episode and we get desperate for it suddenly

Most Americans consider a glass to be 8oz.
So 8x8 is 64 ounces.
Anyways the reason the defined 8 glasses a day is beyond stupid is it doesn’t account for the person’s size or caloric intake.
If you’re 250lbs you’ll prob want 10 glasses. If you’re 150lbs you prob are fine at 5.
And again that would change with calories and amount of exercise too.
8 glasses a day is as stupid as BMI charts
In hot weather it's easy getting dehydrated without noticing, better to drink water proactively than waiting for warnings from your body. Also the colour of your pee can tell you a lot, so if your pee is completely translucent (water like) for multiple days, than you might be drinking too much water, but as long as it's yellow, or better jet light yellow, you should be fine.
lets see - its hot...
Is there such thing as drinking too much water?
You know that feeling you get that says you should drink "proactively"? It's called a light feeling of thirst.
@@MindlessTube Yes, look up hyponatremia.
@@ucdcrush I think you missed the point i was trying to make. Sometimes you don't feel thirsty, when you should already drink a bit.

03:46 “or are elderly” She should have put more emphasis on that! Thousands of elderly (and some not so elderly!) people get taken to hospital every year because they collapse while shopping or walking around town because they forgot to drink. Maybe 8 glasses are too much, but please don’t rely on your body giving you an alarm signal, because that doesn’t always work like it should!
had kidney stones, dont only rely on your body alarm signals. stay hydrated
thirsty isn't an alarm signal its just a sign, alarm is when you are REALLY thirsty. but yeah it might have been better to put a bit more emphasis on that
As we get older our thirst mechanism decreases. This is why the elderly are more susceptible. Plus some take more medications, have more medical conditions which all contribute to dehydration
First place lack of adequate water in our bodies shows up is in lips...they burn, a bit.
Kidney stones are painful. My Mom had them and can create vomiting. She never drank enough water; supposedly stone are hereditary, too. Malarkey?
No one else got stones.
Literally have heard from Physicians, nutritionists, nurses, exercise physiologists. A lot of different people in different disciplines explain that if you wait to drink until you’re thirsty you’re already dehydrated. That’s why you’re thirsty now, your body needed water 30 minutes ago. Obviously she’s a doctor, but I’m gonna continue to drink my gallon a day. Even if its not proven to help people in general. I definitely notice a different between properly hydrated me, and “drink when I’m thirsty” me.
You can die doing this lmao
@@valmiro4164 you can die by over drinking. It takes a lot, and very quickly, relatively to your body mass. It’s very hard to do. Drinking when you’re thirsty is still, years later, not optimal. By that time, it’s already too late. But also, no you should not drink too much water in preparation for something. Just be hydrated.
@@Bigjag15 No it happens often, mostly to athletes. It's called hyponatremia. It also causes edema on top of that.
@@valmiro4164 it’s really not that common, no. It can happen, of course, and of course athletes, mostly in high school do this, but it’s very hard to do actually. Much more common, and a much larger issues in general is dehydration which leads to dehydration sickness, as well as flairs up many more underlying issues, and depending on the temps can also cause more serious issues like heat stroke. Again, if you wait to drink until you’re already thirsty, you’re already dehydrated. Overdrinking can happen, but it’s very hard to do, and no where near as common as dehydration.
@@Bigjag15 You say this like "not drinking enough" is the only cause for dehydration, but it isn't.
I live in hot environment, and I rarely get thirsty, like if I was born without the thirst option.. of course I collapsed a month ago due to dehydration
Bro same. I live in Canada so it’s not nearly as hot but it’s dry, and even when it does get hot my thirst signal is so slight that I completely ignore it 😬
She doesn't have real world experience.
Exercise makes u thirst
Maybe the heat keeps your brain more aware of what water you feel you need?
I’ve had multiple holidays to warmer climates where during an excursion someone in their 20’s (different people) collapsed because they didn’t drink enough. Once a girl needed to go to the hospital for it. if the risk is that people need to go to the toilet for drinking too much, I’d rather have them think that, than that they think they should “listen to their body” when they are warned to hydrate. People are stupid, so they’d better make the safe mistake
I think she's probably right in that you don't need 8 glasses a day. But you don't need to wait until you feel thirsty either. Just drink water throughout the day. I do feel better when hydrated, but I have in the past overhydrated myself while I was sick, drank too much water after throwing up and it made my salt level too low (a Nephrologist told me so in the hospital, I had to eat more to get my salt levels up). I think it's really a case-by-case basis, as everyone's body chemistry is different and probably requires different amounts of water to function at an optimal level. Sort of like how it's healthy when/how long we sleep based on each person. Doctors online give the basics, but it's up to us to take that advice and figure out what works best for us. Maybe discuss it with your own doctor.
It helps prevent kidney stones though...
Yeah and heaven knows that nobody wants those.😬😂😂
2:32, bud
Mr. Tribbiani, I’m afraid you’ve got kidney stones.
Umm, well, what else could it be?
It’s kidney stones.
Or?
Kidney stones!
You can increase the likelihood of getting kidney stones if you don’t drink enough water but also if you drink to much. If you just drink when you are thirsty and it comes out correctly on the other end you are good. No need to over due it or anything.
@@weich1q2w this is so random but I love your name. I actually write books and an "Austin" is one of the main characters to my first book.😂😂😂
I know this is rare, but I know people who adapt to thirst. They simply don't drink. The worst I saw was my roommate in boarding school, he felt sick and could barely move. He was sent to a hospital and the doctor said that he was severely dehydrated. The other one is my cousin, he had to set alarms on when he should drink. He could felt thirst, but he forgot to drink. Silly, right? But this is real.
Some people have the feeling of thirst very similar to a feeling of hunger, so they eat rather than drink, which placates the body temporarily until the feelings return.
@@cattysplat so true! And I think that thesw cues are even more confusing to people in food deserts, people experiencing poverty, or those in information deserts. It’s safer to give a ballpark answer than simply say “your body will tell” because that assumes you know how to listen to it or even that it’s functioning correctly.
I think the whole 8 glasses was just too get people to drink more water, rather than drinks that aren't as healthy, soda, juice, beer, etc.
seemes so, but even with 8 glasses people rarelly taken even half of them
the 8 glasses is a guesswork
since the collective wisdom thinks "oh the body is XX% water and you need X% of you bodyweight in water" the math for the average person ends being 8 glasses
but that concept is outdated, because it dont consider water retention and water from food
people forget that glucose = water, the first thing that happens to the body when you stop eating carbohydrates is you get a lot of dehydration
juice and beer (not in excess) are heathy... and are 90%+ water
I think one thing she missed : always have water by you so you can drink when you feel you need to. I agree 8 glasses or a gallon is too much, I tried it and it disrupted my day so much going to the bathroom 10 times during the workday. Then I looked up the facts, and realized I was doing more harm than good by being overly hydrated.
I know your comment is a year old, this is for anyone else stumbling on this video. Your body will adjust to higher (proper) volumes of water consumption. After a week, the frequency of your bathroom breaks will return to normal (your body needs time to adjust and properly hydrate your skin/organs/muscles). A good rule of thumb is if your urine isn't almost clear, you need to be drinking more water. 1 gallon a day is not going to cause any harm, and is actually insufficient for many people who regularly sweat (athletes, those who work outside in the summer, etc.).
@@GameOn0827 This is important. Over hydration harm is only in those who chug water to an extreme and your body will angrily tell you to stop drinking.
Your body weight, height & level of exercise matters to how much you drink. When I was training for a marathon it was 3L+ of water. Now sitting around working on my computer it's down to ~2L+ and I haven't suffered a heat stroke or bad over-hydration in my life.
A important thing is to listen to your body, but more often than not it's late to telling you dehydration being the best example. It's better to increase your amount of water finding a suitable amount depending on yourself then sticking to it.
Wasting so much water flushing that toilet
Theory is really beautiful, but reality says: hey, kidney stones😉
Well kidney stones can be caused by eating to much sugar/carbs which causes insuline to rise which causes kidney function to be diminished so that it cannot always correctly get rid of all the salts. Fix your carb intake, lower your blood sugar, which will eventually lower your insuline level, which enables your kidneys to recover and keep the correct salt level in your blood. Also eat less of the legumes and vegetables that are high in oxalic acid because oxalates easily crystalize in cells or on kidney stones or gall bladder stones. Eat the vegetables or legumes that are low in oxalates.
Also sugar in your blood means that your blood turns slightly acidic which is dangerous so your body balances that out by retracting calcium and some other salts from your bones to make you blood less acidic. But that increases salt level in your blood which your kidneys would want to get rid of but has an issue with so the kidney stones grow. Also it causes osteoporosis eg weak bones because they slowly deplete of calcium and magnesium and some other salts.
FYI: osteoporosis is also called diabetes type 3 and alzheimer is called diabetes type 4.
kidney stones, UTIs, pyelonephritis ... could cause a lot of things really ....
@@jo-han there are at least 3 types of kidney stones and all due to different reasons. Mine were due to high consumption of purines for example
@@RachelMurrdererWolf Mine were caused by the amount of magnesium I used to eat. Other people I know were caused by calcium. No amount of water will change getting a kidney stone, just might make it pass slightly quicker. Assuming it doesn't get stuck like mine did, requiring a Stent.
@@beepboop9464 This is not true at all. Most kidney stones are formed when supersaturation takes place. That will only happen if you dont drink enough water or have some other health related issues. If you always pee yellow-ish clear pee theres no way for the amount of calcium, oxalate, or phosphate you need for kidney stones to be able to accumilate
RUclips comments (as usual) missing the point, giving random personal anecdotes. The point of the video is that 8 glasses a day is not a hard rule and is somewhat arbitrary, and that you can maintain healthy hydration without succumbing to overly generalized pseudoscience statement (given that excess hydration doesn't scale in terms of health benefits). Understand your body has its own tools it uses, and by understanding that you can assist it to make sure everything is gucci.
while i like the myth-busting approach in this video, i think its too short and ignores to benefit of drinking water. because most of the people who need rules like "8 glasses a day" nearly never drink water so things like: not drinking your calories, helping with digestion, making you feel full, etc. should be mentioned. psa's are great, but this one is too simplified and might lead to further misunderstandings
This is so important!
So you think we need nonsense like 'drink 8 glasses a day' because the science of 'drink when you're thirsty' is too complicated a message? Riiiiiiiiight
@@MrJKJKJK1974 not everyone listens to their body tho, some needs to be pushed to do what they need to do. plus, what if im hungry all the time, so should i listen to my body and just eat every minute
@@MrJKJKJK1974 yes. My body often not giving thirsty signal properly (and I believe I'm not the only one like this). I can 'forget' drinking water a whole day if I'm busy. 8 glass of water is a good standard for me because it's easy to count.
@@selle.662 good point
I wish I could be MD and tell all the patients “just listen to your body!”
I had kidney stones (it helped me find i had a cyst, but anyway), trust me you dont want them... the answer to that is stay hydrated.
This video is bugging me, why would you argue with ingesting more water ?? there is no such thing as too much water (except in extreme cases). the important thing is to drink whenever you are thirsty (even just a little), and add a few random occasions to drink.
Stay hydrated, stay healthy.
Drink when you are thirsty, and a little more. and avoid these fu.... stones
Well I agree. But water poisoning can happen really fast if you don't have enough minerals in your body.
Well, there IS such a thing as too much water, but it would take way more than 8 glasses of water all at the same time.
8 glasses of water spread throughout the day is fine.
@@warlord-chan9540 It's more like the minerals in your body are diluted too much by excess water. Without the excess water, the minerals could have been sufficient. It's about the concentration of minerals, which changes with the amount of water.
Exactly! I was 11 when I had my kidney stone, and as a kid I was too busy at school to drink that I just didn't, missed all the warning signs of 'thirst' and volia, kidney got removed along with the stone, and now when people say they haven't drank any water that is a really serious & personal matter!! Please stay hydrated people!!
@@niccolom yeah I guess. What I meant was the mineral intake should go up with the water intake.
I work in the military, and train physically 2-5 hours a day. In summer heat I often end up drinking over 4 litres in a day.
Cause my body is telling me to.
I literally had tachycardia, fainted multiple times, and looked like I was on drugs just because I was dehydrated. And I was drinking water, I thought I was drinking enough of it but I never realized that I wasn’t drinking enough until I was in the back of an ambulance!
You need to have salt intake, salt will keep water in the body.
@@danielberei3021 Yes, I did know that.
@@danielberei3021 I feel the need to add that salt also dehydrates you!!! yeah we need salt but don't go eating more salt because this comment told you it will help you stay hydrated, you can die from eating too much salt so fast, it's a really painful death.
@@ActuallyLemonshave you got any proof evidence or study that anyone died because of salt overdose? You haven't done it because you are still alive, right? So, why are you talking nonsense. Yes, it is clear that you can go I'll from everything, even something that is healthy. But in the case of salt you have a set of organs that protects your body from low salt intake and even overdose. Those organs are your kidneys. Bet you are a kid too and only live on packaged so called "fooda" and vegetables like pizza
@@ActuallyLemons As a kid running a ton I consumed too much salt at one point before a big race.
By the end I sweated out so much of it-it visibly crystalized on my skin more than I had ever seen. If you don't drink plenty of water/exercise and consume tons of salt you'll for sure be bringing yourself to an early grave.
Hi everyone, I know I'm gonna get some lashing and heat for this but over the years I've realized that no one else really lives the way I do and always wondered why people drink and eat the way they do. So here it goes. I don't drink water at all. I get it in the form of foods. I eat once every other day. I run 20 miles a day. I am 44 years old and I am super healthy. I'm 5'10". 170 lbs and ripped. I do not drink alcohol, smoke, or even take aspirin. I know that this.all sounds ridiculous and idiotic, because tbh no one else I know lives like this. I do truly believe you have to listen to your body, and not believe every single thing someone else is telling you to do with your body. I've lived like this since I was a child. Never drank milk ever in my life.either. I'm extremely active and no one my age can keep up with me, and hardly anyone in there 20s for that matter can either. That is not me bragging but the honest truth. I know I'm an anomaly but this is my life experience and I am not telling anyone or suggesting anyone to live like this, I am simply sharing my life with you.
its when a start to have a headache and eye fatigue that i know that i am dehydrated.
Sadly, its take a whole hour after drinking for the headache to leave.
getting into the habit of taking a sip every hour is clearly a good thing...
Definitely. If one would always wait until the body *needs* water, headaches would eat your alive sometime. Even if apparently it’s not necessary to drink 2 liters a day, the habit of drinking a sip every hour is really a good thing if you want to avoid headaches or other pains.
I love this presenter she's got great charisma
Another key thing to note is that medications can influence how much water you need as well. People on lithium - a salt - need to stay very hydrated in order not to get lithium poisoning.
Yea, but if you're on a medication like that, generally your doctor is going to inform you of that and let you know that you need to drink more water because of that medication.
That doesnt really apply to people with normal functioning bodies though who arent on medications. If you have a specific reason why you need to drink more water, then your doctor is usually going to inform you of that, and in that case, yea, listen to your doctor.
Otherwise, paying attention to your bodily signals and drinking when you feel thirsty is good enough for anyone with a normal functioning body.
Glad I read the comments--- I'm one of those that drinks a ton of water each day, especially when I first wake up. I feel like it cleanses me internally and it definitely has done wonders for my skin as opposed to when I drank significantly less. I know when I'm dehydrated when I'm dizzy and about to pass out which has happened once, maybe twice in life-- I otherwise don't know what thirst feels like per-say, but I love consuming beverages. I sun agree with her take on water.
honestly i just look at the color of my pee, and adjust how much water i drink
Who even measures the amount of water by glasses?? There are barely any glasses the same size at home

Imho, there's a slight flaw with Dr. Jen's advice, in practice-many people in modern societies confuse thirst with hunger, so just "listening to your body," to paraphrase, won't work well for many people.
That's true! Usually, when youre hungry you just need to drink. If after drinking the hunger is still there, that means you want to eat :D It works for me
This was the case with my girlfriend of some years ago. She drank so little water but ate to full and nausea as a very small person, that one day she called me in some distress to say her urine was clear. She had never had clear urine. I have a good water habit, so when she picked that up from me, the change was stark!
Nice Urban Myth / Wive's Tale :) Show me the science behind your claim :) Please stop posting online if you're not going to have legitimate and valid ideas :)
Who would confuse hunger and thirst? And why only in "modern societies"? Still, if your body needs water and you eat, your body will pick the water from the food
@@thecommenter578 Unless it's salty chips.
tell this to literally all of my neurodivergent friends who struggle to interpret "internal messages". Nice idea if it works for you but some of us really need a guideline
I was looking for this comment! As someone who is self diagnosed ADHD (still waiting on a referral from 3 years ago) I struggle with interception, and this means I'm often going 3/4 of the day on a morning coffee and a glass of pop (for hydration). The days where I "drink when I'm thirsty" are the days my ADHD is at its absolute worst, and I get horrific headaches and feel generally terrible. This video is quite worrying as I feel like it's based exclusively on theory, and based on a neurotypical, able bodied person. The variables here are so massive that I think the best catch all advice HAS to be to drink regularly
As we get older, we are less thirsty and more prone to dehydration, so we need to keep a certain amount of water in mind.
This video will bring more harm than good. Good job.
It's just explaining biology. If you believe something contrary, try providing some reasons why you think that way.
I mean, isn't that what this video is meant to do? lmao
I don't drink eight glasses of water per day, I drink at least a gallon and a half per day.
And it feels amazing. I strongly disagree with Doc on this one. I feel weird when I don’t have my gallon a day. Definitely helps with skin as well.

@@MrAntsunator not at all. Just someone who’s been faithfully drinking a gallon a day for since I have 15(Soon to be 33) and just speaking from experience.
I love reading how defensive everyone is getting of their 8 glasses a day. Just because it seemed a simple fix, doesn't make it right. If people only ate when they were hungry they would probably be healthier. Other than those with dementia or other memory/thought function impairments, people remember to drink. If you remember to eat, you will remember to drink. You may fail to do both if busy, but not to the point that harm will happen. Her point is that an arbitrary rule, followed blindly is not good science. And it puts the control of your body into the hands of the people who make those types of rules, regardless of the science or nuances of your own needs. If you exercise hard, 8 glasses wont be nearly enough. If you have small glasses in your house, you may need more. Think about what would show you that you are drinking enough eg the colour of your pee and how you feel.
I regularly confuse the signal for thirst with the signal for hunger. The implication that your body has a flawless method of informing you how much water you need is almost certainly more harmful than advocating people drink 8 glasses a day.
My body tells me I need water when it's too late. I always have a water bottle near me within my peripheral vision so that I drink water often. Despite what this lady says, I felt healthy and my skin health visibly improved. If I fail to drink alteast 8 glasses of water a day I feel like a zombie(sick and sloppy/tired). This applied to my parents and friends too. So I suggest you guys to take this vid with a grain of salt.
Agreed
Probably placebo.
8 glasses a day is a completely arbitrary amount with no scientific backing. If you are needing EXACTLY 8 glasses a day to feel good, its almost definitely because you are victim to the placebo effect.
You only get 7 glasses, realize you didnt get 8, think you're going to be sick and dehydrated cuz of it, and then do feel that way because you think you will.
For the vast majority of people, 8 glasses of water is way more than they actually need. So if you drink like 6 or 7 glasses, you shouldnt really be feeling any of the effects of dehydration. The fact that you DO very strongly indicates that its just the placebo effect.
One thing that you can do to actually check, is check your pee. If your pee is mostly clear or slightly cloudy (as in a light yellow), then that means you're not dehydrated. However, if your pee is a darker yellow or orange, then that means you probably are dehydrated. That is a much better indicator of how dehydrated you are.
So if you have normal looking pee, but you still feel dehydrated, its probably just the placebo. If you do have darker colored pee when you only drink like 6-7 glasses a day, then you might be one of the few people who actually needs that much water in a day.
But the vast majority of people do NOT need to drink that much water in a day. Unless your body is losing a ton of water through other means, you dont need that much.
I’m not waiting for a thirstiness.minimum 2liters of water in a day and I’m feeling very refreshed .know what my organism needs and how good it’s for my inner and outer hygiene.
I feel like I can't completely count on my body to let me know when to drink. I do feel clearer-headed and energized when I consciously add extra glasses in throughout the day.
Sorry to contradict, but it does improve my skin, and it makes me clearer headed and more alert too. I only upped my intake to help my skin, i didnt know about other potential benefits, so it isnt placebo.
Why isn't it placebo?
@@apaaaa that's not how science works
@@knucklesamidge Because i had no awareness that becoming more alert/clear headed was a possible result of drinking water. I'd never heard or read that before.
I'm also a skeptical person, so the first time it happened i didnt conclude that it must be the water alone, but it happens whenever i drink 2-3 glasses in quick succession. The time of day doesnt seem to make a difference either.
Re my skin, it does seem to contribute to clearer and healthier looking skin, but i acknowledge i had the expectation of this result.

@SpodTeK Yes, when I increase my water intake it's every 45min-1hr 🙃
My urologist said to prevent kindey stones take your bodyweight in lbs and divide in half equals how many oz you need minimum.
That is just a guideline that hasn't been validated by science. It is just a nice guideline. Doesn't mean it is wrong, but a lot more variation then that guideline is also probably right.
Kidney stones can also be caused by eating to much sugar/carbs which causes insuline to rise which causes kidney function to be diminished so that it cannot always correctly get rid of all the salts. Fix your carb intake, lower your blood sugar, which will eventually lower your insuline level, which enables your kidneys to recover and keep the correct salt level in your blood. Also eat less of the legumes and vegetables that are high in oxalic acid because oxalates easily crystalize in cells or on kidney stones or gall bladder stones. Eat the vegetables or legumes that are low in oxalates. Your urologist should know these things if he is up to date with the science.
Also sugar in your blood means that your blood turns slightly acidic which is dangerous so your body balances that out by retracting calcium and some other salts from your bones to make you blood less acidic. But that increases salt level in your blood which your kidneys would want to get rid of but has an issue with so the kidney stones grow. Also it causes osteoporosis, eg weak bones, because they slowly deplete of calcium and magnesium and some other salts.
FYI: osteoporosis is also called diabetes type 3 and alzheimer is called diabetes type 4.

I need between 2.2-6 liters of water a day, which is more than 8 glasses, so I certainly fall into the 8 glasses *plus* a day category. You'll drink when you're thirsty *if* you have water available. I always keep a full mug of 20oz water on my desk, and I reach for it subconsciously. Always keep water available and you'll probably develop a better connection to your thirst gauge!
I always have a waterbottle by my desk and I don't really instinctively reach for it unless I'm on a video call, then I have this weird nervous habit of constantly taking sips from my bottle haha
well yea, if you're actually thirsty and legitimately drinking that much water, thats different. Some people do drink a lot.
But the point is that everyone's bodies are vastly different, and the 8 glasses a day thing is COMPLETELY arbitrary. It has no scientific backing whatsoever. Some people need more than that, and some people need wayyyyyyyy less. It really just depends on your specific body.
So the whole point is that you shouldnt listen to the "8 glasses a day" thing. Instead, you should drink when you feel thirsty. That way you give your body how much water it actually needs.
If that does lead you to drinking more than 8 glasses a day, thats perfectly fine as long as you were actually thirsty for that water and werent just forcing yourself to drink more water. But in general, most people are not going to need 8 glasses a day.
She is a gynaecologist. Why is she the one talking about water? I would be more comfortable with someone researching about this giving a TED-Talk.
This seems to be condensed video version/a video summary of her podcast. It is linked in the description. On there she talks with experts about these topics, in this case a nephrologist. So here info comes right from the source.
But even without the podcast, these kind of TED-Talks don't have to be written by the presenter. There could have been an expert at least reading the script over behind the scenes.
To be fair though, TED should have been clearer about the creators/background of this video.
@@xXbubbelXx I had read the description. It is rather generic without much value so thank you for clearing it up.
Ya, we often get most of our water from the food we eat on most days. Also, a slight dehydration can feel more like hunger, its often helpful to drink a small amount first when feeling hungry as light thirst can be confused for hunger and cause unwanted over eating.
well, generally drinking when you eat can be good anyways. It can also help lubricate your food too.
Really funny how she completely ignores the fact that her entire argument is based on people listening to their body, when in reality people can go without food without noticing it for literal days because we live in a society with next to no downtime, a lot of stress a lot of distractions. And in the flow state you don't really notice much of anything outside of your tunnelvision. You don't need to drink half the ocean everyday but you gotta set time aside to listen to what your body actually needs.
"Really funny how she completely ignores the fact that her entire argument is based on people listening to their body" Huh? Perhaps you missed it, but that's the EXACT POINT she's making - don't just mindlessly drink, only listen to your body.
it’s actually good to go without food for 12 hours, 24 hours or longer. People with 28% body fat can literal fast for days without a problem because the body is made to handle long periods without food. There are doctors who have helped thousands of people reverse type 2 diabetes, arthritis etc. But the same doctor you see will prescribe you insulin because that’s what they’ve been told to do..

I usually drink about 3L of distilled water everyday. "If you feel thirsty, you're already dehydrated".
Distilled really? That's dangerous
The problem is that many don't know what "dehydration" means. If you're thirsty, you're thirsty. If you're dehydrated the body is really lacking water. Saying you're dehydrated because you're thirsty would be like saying a slight feeling of hunger means serious starvation. It's a gradient.
Is was thinking along this line.
Yea, the saying of "if you're thirsty, you're already dehydrated" is so dumb.
When you're thirsty, your body needs water and its telling you that. But you arent in a SEVERE need of it. Just like you compared with hunger. When your hungry, your body needs food, but its not a severe need like starvation.
If you drink when you're thirsty, then youll never have any negative effects from not having enough water. Thats the ultimate point. You dont need to preemptively drink just to avoid going below 100% satisfaction of water at all times. Needing a little bit of water isnt going to hurt you as long as you actually drink water when you need it and you do feel thirsty.
Important to note how drinking alcohol and caffeine excessively leads to dehydration which leads to other problems. For many people they don't see this as logical, because I am drinking liquid so I should be hydrated. A habit of drinking large amounts of caffeine and alcohol everyday will inevitably have consequences, that's where this crazy advice I believe came from, so people could continue their excessive habits and try to compensate with silly amounts of water consumption.
I agree with you totally.
Speaking from someone who has lost a kidney due to kidney stones and dehydration, you SHOULD drink water as your body can easily be ignored accidentally (especially if you are a child in classes or glued to the TV) when it is asking you to drink water. Stay hydrated please!!
Yeah, this anecdote of non-medical expert dismisses everything what is said by real doctor.
Yeah....I'm still drinking my 8+ glasses thanks
Well clean water won't hurt me so I'll stick to drinking a lot of water each day.
Peeing a lot is good.
Clears toxins and sugar from blood.
Hence drinking loads of water is good.
She looks like a Hogwarts teacher
Yup🤣🤣
Since the age of 15 I’ve always enjoyed drinking water. I do suffer from kidney stones which is very painful but I imagine if I didn’t drink as much as I do it would be extreme
These video is a collection of right scientifical facts that bring to wrong conclusions. If you are not used to drink water, you will have a lot of retention and you will hardly ever feel thirsty. But that does NOT mean that you should not drink more.
This is the most questionable Ted video I've ever seen
Yeah I'm not really buying it that our bodies will tell us without fail when it's thirsty, or that we're not already slightly dehydrated by that point which most doctors say to try to avoid. I tried listening to my body with food for the first 20 years of my life, and it didn't work out for me. As a kid, I remember being in the 80th percentile for height but 5th percentile for weight. I ended up needing to be hospitalized because I was so sick from inadequate calories... turns out that my body doesn't know when it's hungry and I need to be on a med to stimulate my appetite. It's considerably easier to eat now, and I've gained 40 pounds so that I'm finally at a healthy weight. I imagine some people experience the same thing with water, especially if they're stressed or super busy.
@@renee3461 this is true. In general, humans don't necessarily show symptoms of problem but shows signs in the laboratory results..
Yeah exactly. 8 glasses of water a day is itself not an clear measure, we must drink 3-4 litres of water a day. Specially in summer, the more the better.
@@emmastone6496 LOL you will have 4 liters of urine if not more. No body needs so much.
Ok so I work as an carpenter and sweat like 2 Liters a day but don't feel any thirst. I almost Collapsed because I forgot to drink, and you want to tell me that this is normal? I have to force myself to drink or i probably just die. But ok
It’s anecdotal, I know, but the $1000 ER bill for a child who forgot to drink tells me we should probably be checking the color of our urine, and have a basic water consumption goal regardless of how god our bodies’ signals are
Super misleading video. Basically asks you throw out all the education from sport and physical science. If you're body is at the point where the urine is concentrated (super yellow) like she talks about, your muscles will already be fatigued and facing cramps. The thirst response is a sign you are dehydrated and it takes at least 45 minutes for any water you drink to show it is rehydrating. By that point your body will already be broken down or you could just pass out, unless you stop and cool down entirely.
So maybe you don't need 8 glasses a day if you live a sedentary lifestyle, so for the average person, not a big deal.
For kids and athletes trying to learn how to prepare for anything strenuous this video is not just misleading, but borderline dangerous. Lots of kids, adults and elderly folks die or go to the hospital every year from heat stroke (hand in hand with hydration) and severe dehydration. PSAs are good, but discouraging folks to hydrate themselves feels dumb.
too true. I pass out if I don't drink before and after exercise.
Yup my son collapsed on the treck circle and EMS was called for heat stroke ☹. Hadn't drank anything but pushed to run in 100° heat. I was sups angry and freaked.
I love this woman!
Great tip : drink when you're thirsty... And eat when you're hungry, that's it 👍🏻
Eat when you're hungry depends on your habits tho
You can drink more and eat more out of habit, you'll feel hungrier a few days after those BIG meals because you've dilated a bit of your stomach volume and that sense of fullness isn't the same
Water is important always carry some with you and drink through out the day. I watched a terrible news a wrestling boy died from dehydration because his coaches refuse to let him drink water until he finished training. At the end they lied and told to give him water and told him to go find yourself. Every doors were locked that day even fountains were emptied. He died and his peers were pressured to not help and watch him run for water.
As a person that usually drinks tea just out of boredom while studying (so I drink more like 4L a day) I can tell, that when I go to work on my car, and it takes me say, from 8 am to 10pm, there is a good chance that I won't feel any thirst, because I am actually focused on something.
And that's where the 2L a day come in. Just as a number for people who are doing their job and do not feel thirst, hunger, pain... because they are focused.
And don't tell me that it's fine then. One day every month, maybe it's fine. But if someone is living that way every day, he'll get kidney stones. (Which are an obvious sign that apparently it is very well possible that people can have too concentrated urine and still not drink.)
Oops, this is the real problem, following your “listen to your body” mantra! Completely agree with you. Another way could be, when we are stressed, our normal body function changes a bit, we might less, or we might eat high, we might need not drink! Then, how can we trust our body signals when we are on stress !!
Potentially dangerous in people drinking even less water that they do already..
Having ADHD and PoTS means I can't always tell I'm thirsty or get hyperfocused and my meds for that make me sweat more, but I need to drink 3L (about 12.5 cups or 100 fl. oz) minimum in a day to keep my heart rate stable and to feel alright so I'm not sure it's wise to tell people to rely on their body signals - people don't necessarily know they have ADHD and therefore can't drink consistently without reminders or conscious effort, nor do they realise they have PoTS, so without the idea of 8 cups a day in their minds may be chronically under hydrated and suffer quite bad consequences of this 🤨. I know I got very bad with heart rate spikes and fatigue because it never occurred to me that even what seemed a normal amount of water and salt isn't enough until my Dr told me to increase them after I'd been struggling for years 😂
Smile 😊
How you feeling today ?
ADHD'er here. I completely agree. I drink 3 litres every day, and it helps me cope with common side effects of ADHD medication, like headaches or heart palpitations.
This doc really good, kindly make more videos with her
I just like to drink more water and I don’t think that’s a problem
Overhydration can lead to water intoxication. This occurs when the amount of salt and other electrolytes in your body become too diluted. Hyponatremia is a condition in which sodium (salt) levels become dangerously low.
This was really interesting! I now have a deeper understanding on the biological aspects of hydration and the effects dehydration may have! Thank you!
I stopped trying to drink so much water after watching this video, and I got really constipated. You don’t need to drink eight glasses per day, but you still need to make sure you are drinking enough to keep your bowels moving!
I so much like Dr. Jen. She is the best.
I get olympic-grade cramps in my abdomen, legs, and shoulders when I move in whatever my body decides is the wrong direction at that moment. They are debilitating and can last from seconds to up to 20 minutes. I'm never thirsty when it happens but getting to and chugging a bottle of water will fix it in a half hour. It happens more often during a week when I am doing a lot of physical labor but doesn't cramp at the same time as the physical labor (usually, not exclusively). I disagree with your assessment of just listen to when your body says to drink water. I don't drink soda or juice and sometimes have a small coffee in the morning. I don't know if the fact that I almost exclusively drink water (because I literally live in a desert) has anything to do with that but thought I'd mention it. The cramping got much worse when I hit 35-ish. I went to my dr about it when it was just leg cramps in the night years ago, but he said there was nothing wrong with me and I just had to deal with it.
What a jerk. Maybe find another doctor. They don't generally consider nutrition. Allopathic medicine is about drugs and surgery. I picked my doctor talking to a pharmacist. Best choice I ever made for my situation. Plus she is hip on nutrition.
People always say: drink only if you feel thirsty. It's comical.
What if a person's lifestyle is drinking alot of tea and liquid carb to soothe thirst. These people often don't like drinking water. I personally think it's much better to reinforce 8 glasses than no numbers at all. So we have a measurable understanding of how much we must consume to be healthy.
Because if you actually start to drink proper amounts of water. You wouldn't even count if you reached 8.
Well the same body tells me to watch Netflix series while i am trying to study.
stress is not good for the body in a long run. Thats why your brain leads you to watch Netflix
ahhhh, I am so happy that now I can share this link with those who told me "we should drink x glasses of water a day". Thank you so much!
RIP your kidneys.
Next video: Are vegetables really good for you?
Fr😂😂😂😂
"You are eating too many veggies!"
Yeah never heard such BS. Do you really need to breath constantly. Only breath when you feel the absolute need for it.
It does helps my cellulite, and keeping a bottle next to me actually makes me aware that I’m mostly thirsty not hungry.
I drink more like 15 a day
yup me too wayyy more! are we abnormal 🤣
do you live in the bathroom? lol!
I think this applies to perfectly healthy people, which, is like 10% of people. Most people are shoveling dry, processed food, caffeine, sugar, alcohol, supplements, medications, excessive salt, recreational drugs, nicotine, and who knows what else down their throats, drying their bodies up, dulling the internal mechanisms that signal true thirst. The confidence she's speaking with is kind of repulsive. I've heard hydration explained every which way by doctors, nobody ever agrees across the board on hardly anything.
I take creatine so I drink about a gallon of water a day. I do notice I feel a little better when I’m very hydrated.
I once realized, when it was 9p:m , that I haven’t drunk a single drop of water since the day before, same hour, and I wasn’t even thirsty.
Sometimes you can’t trust your body and you just have to take actions.
I live near the equator and I don't monitor my water intake but I'm sure I don't drink 8 glasses a day and my urine is a very pale yellow, my kidneys function fine and I'm healthy. What she says is true for many people.
This is a really interesting matter, I'd love to check some scientific papers on the subject, if they exist.
they do and some show its too late when you are thirsty.
I live a healthy lifestyle. I only drink water when “facing real dehydration” and am forced to “do whatever I need to get it”. Just like I only sleep when I physically collapse to the ground due to extreme exhaustion. My body tells me.
Valuable information for us and thanks Dr. ...
I rarely ever feel thirsty, but my mouth and lips get extremely dry. What’s going on here?
Best guess is you either live in a very dry area or you're experiencing the early stages of dehydration and your brain isn't giving off the proper signals.
You adapted to drinking very little. To feel enough thirst for more hydration will now require effort to change your adapted state.
I recommend to use bottles and straw's you carry with you. You'll probably start drinking more, simply because it becomes easily available to you and doesn't require to keep the signal in your working memory for a long time. It's just a sip away =)
I agree with this video, I was actually doing a search of why do we need to drink 8 glasses a day because I don't think we do.
