Who else is watching this, while having a cold? :(
Me 😢
Not me definitely, just getting some knowledge to have some interesting talk with my imaginary friends
Me😭😭
Me😪😔
👋
No joke, this video was actually reassuring to me. Even knowing, as you stated at the beginning, that colds are caused by viruses and not temperature, as silly as it is the fear part of my brain kept telling me that being cold = getting a cold. Thank you for real.
If cold weather were the reason people get colds, Norway would be a nation of coughing and sneezing people.
Canada; *Have you forgotten About me?*
@Shane Stephen literally no point made.
@@franzferdinand2240 Russia: hello there
@Shane Stephen what the hell are you trying to say
Imagine South Pole (-45 degrees Celsius)
0:51 "They put virus infected mucus up some of their nostrils." Nope, I'm snot doing that.
Master Therion lol
I feel like you watched powerslap entertainment on making funny comments
Master Therion Also, how many nostrils did those people have.. 3? 5? 8?
I'd do that for money
Get out.
but the bigger question is
Why don't we get hots when it's hot?
Sure we do, if you're a tv show character or from the 80's "hots" means horny, what do steamy showers do to your mood?
Why is man's not hot?
Tell Me This because man's not hot.
steamy showers make me sleepy
we do, but only at the minimum heat of 38 Celsius, if you stay under sunlight at that temperature, you surely will
Do people in winter months get sick at the same rate in a northern area like New York opposed to a southern warmer climate like Florida?
I don't have a scientific answer for this, but I just got back from Florida with a cold, which I thought was a little bit weird. But it was WAY less humid than when I went in the summer, so I think winter colds still apply because of dry air.
Some Asian cultures have an excellent way of helping reduce transmission of airborne illnesses: folks who are ill with colds, flu, or such wear surgical masks to help lessen the chance of spreading their disease. Last week, I knew I was sick with an influenza-like illness (ILI), so when I went to the medical clinic that handles my needs, I showed up with a mask on my face and instant sanitzer for my hands... because the coughing element of the illness was really, really bad, and I didn't want anyone else getting the nasty virus ravaging my lungs and bronchii. (Same illness sent roommate to hospital for 4 days, so I didn't at all mind looking ridiculous, if it would help others avoid the same fate.)
This aged well
Looking ridiculous. Heh. Now it's normal. Who would've thunk?
Comment still holds up lol
All these videos helping me not get sick this season. Thanks SciShow!
You cannot pay me enough to put someone else's snot up my nose.
Fsilone what about in 60 years when you have to get a fecal microbiota transplant to keep your GI tract healthy?
Sooo, you would snot do it?
$2500 cash, you would
HIV isn't airborne...
Even if it's from a hot girl?
Last Christmas I had a cold and couldn't be merry and give any of my family members a hug
oh that's sad...
I am having a pretty low day but thanks to Sci show once again for providing a joyous distraction from my existence in this fiery hell we call life 😅
Kirstie T
Here's hoping your day day gets a little better.
:-)
Kirstie T I don’t relate at all I had a good day
And Thank You to whoever is loading these videos so that they are available for us through the holiday week. You are making a difference in the lives of those that are looking for entertainment during the week between Christmas and New Years Eve.
The term cold is relative, for example, today in my region it was -19C but when up to -10C everyone said "Hey it's not too bad now" but someplace like Florida from 30C to 21C would freak them out and they'd probably think they will get sick.
Just a few days ago I saw in The Guardian newspaper it gave tips on how to not get sick and one was to make sure you change out of damp exercise clothes in case you get chilled. Ugh!!!!
Here’s a question: can you “sweat out” a cold or fever through exercise? My father (a gym teacher) always insists it’s a real way to help get better.
Yes it does work buddy 😊
From googling it, I found an article in Medical News Today that said that "no you can't" and that there is no scientific evidence to support you can. Which makes sense to me, frankly. Your body would probably benefit more from rest so it can focus on fighting the virus.
Yes this does help, however, people feel really bad which makes them unmotivated and thus avoid exercise making them stay sick longer
I always get sick at least one time in the middle of the winter. I only got sick in the summer one time in my life I can remember. But it was when a unusual cold spell came through the area that summer. So I think it has something to do when your outer body cools down compared to when it's warm in the summer
2 weeks ago I went drinking with all of my colleagues, there was like -5 C° temperature, I was talking to someone for like 10 minutes in a simple t-shirt, with a lot of alcohol in my blood, next day didn't had anything that would be symptoms of being there, just the alcohol, even that wasn't really bad.
Maybe believing in my own immune systems strength makes it more effective.
And me that almost never wash my hand, doesn't avoid at all any risk of getting sick. And i never get sick.
Well. I'm pretty sure if you keep your Immune system very active (which mean to not clean your hand every single time) you can survive much better against infection from all around.
Dude, that's cold.
PaleGhost69 *hot
First part of video: Don’t go outside. Stay indoors where it’s humid
Me:Got it
Second part of video: Go outside. Inside is dangerous
What do you want me to do, SciShow? Live in the door?
i read this as "why do we get cold when it's cold" and was extremely irritated for a moment.
😂
I work at a school and take part time jobs in the summer. I worker for a food processing plant that was 34' wearing only a sweatshirt. I never got sick once. The place was extremely clean. Then I went back to working in a school and was sick within 3 weeks.
With the sunlight and cabinfever associations, it actually sounds like it's staying in, not going out in the cold, that make us sick. So, we need to reverse all our winter advice, and take more walks in the snow.
In Boston right now it's -2. wind chill of -20. Remember that next time you _think_ you're cold. Happy new year everybody
I always figured it had something to do with being more indoors and in closer quarters with people as opposed to during warmer months.
I usually watch RUclips content at 1.25 speed because i subscribe to so many people and I dont have all the time in the world. I thought I still had this setting on but nope, micheal was just talking really fast lol
I run videos at 1.25 or 1.5 too. For some folks that speak slowly I go with 2x speed. Saves lots of time.
Very interesting and worthwhile video covering many research studies.
Michael Is a great host for scishow, always so entertaining! 👌🏼
Aaaand I'm watching this while I have a cold. Good timing.
It’s probably in the mind!
Too good a video .. A question that was on my mind for years.. finally got my answer
THANK YOU! I'm SICK and tired of hearing people saying this
In Soviet Russia the cold makes you hot
I try to stay away even from people who are not infected with anything, along the whole year!
We need more Michael. Give him his own show.
That was one of the most useful bits of information I have ever heard. Why does it take so long for understanding to find me?
I've had 3 colds this year, all during warm weather. The thing about dry air makes sense, since i live in an area that has very low humidity all year round.
I mean, there isn't really a "key", even otherwise healthy people get sick sometimes. Anyway im pretty sure i was just commenting on the possibility of the dry atmosphere contributing to the last few colds i caught... not looking for your 2 cents m8 lol
You just go around giving unsolicited advice huh. It's funny how you said "my situation" but all i've said is that i got sick 3 times this year. I've never given you any indication of how healthy or active i normally am, how hydrated i am, or how long my colds lasted. That's all your assumptions. Just like you assumed i wanted your advice lol. This is really funny though thanks for the laugh. And hey im happy for you that your health is apparently excellent. Good job. 👍
Hoo boy, thank you doctor. I'm super lucky to have such great health insurance. Now how much do i owe you for this consultation?
The indictment of dry air is news to me; that's helpful to know. I learned, iin adolescence, that "lots of sleep" also impedes sickness from colds.
I have a cold now, I had a cold in the middle of the summer this year. So far, the summer one appears to have been worse.
I really wanted to know the answer to this for a long time, thanks!
If being indoors more and dry air were the cause of the cold and flu season, then we should see the same thing occur in desert climates in the summer. Not only is desert air already dry, but air conditioning dries it out even further. If you take a look at places where the temperature is well over 100 degrees, you will find that people spend a lot more time indoors, with air conditioning. Yet I don't believe there is any matching spike in cold and flu illnesses under those conditions.
I've noticed it's not so much the temperature, but rather the sudden changes i temperature. When it's 5 degrees, one day, then warms up to 37 the next day the body reacts differently. Dropping below and then back above freezing temperatures seems to wack out the body spending less resources on fighting infectious things everyday and more on keeping our body at the right temperature. If you work out really hard and then go into a colder environment, then back to working out you may find yourself fighting a cold in the next couple days. Athletes who work out and endure cold weather and hot weather regularly in their exercise and training build up a stronger resistance to catching colds this way.
SDD525 it just did this morning, it was -4 degrees and then once the sun came up it was above freezing, 34, 35. I also work in a freezer sometimes and walking in and out of changing temperatures forces my body to work harder. The cold isn't making me sick, but lots of changing temperatures is putting strain on my body. Just like you going outside in the winter to inside where it's warm.
This is very simple.
You catch colds in the cold because the temperature difference between the outside air and the air in your sinuses causes condensation. This condensation (perhaps caused by the hypothalamus increasing your internal temperature) begins to drip out of your nose when awake but when sleep drips down the back of your throat and lungs. Over night infection sets.
One of the best way to prevent SORE THROATS is to elevate your head so a runny nose doesn't drain into your throat and lung but rather out your nose. (lie on your side with head elevated high) I guarantee you avoid throat and lung infections every time and minimize sinus infections. (Remember the worse time for a cold is while you sleep because these fluid pool in the sinues, back of the throat and lungs as you sleep. That's why you feel worse every morning but get better as the day progresses)
Shame i cannot become Hot when i get Hot
Eastyy you’re actually first 🤔
OG 1st
Eastyy "man's not hot"- big shaq
Honey Sweet 5th
Man can never be hot
I caught more colds when I lived in Texas than I did when I lived in Minnesota.
I don't think it has anything to do with humidity. In Belgium air humidity remains at an average of 80% while in summer it drops to 70. However people still easily catch a cold in and around winter.
Lord Thanksalot 80 % refers to 80 % of the maximum amount of water the air can hold at that specific temperature. The amount of water the air holds increases with temperature.
Well you cant back that theory up without numbers, first the humidity difference is not changed that much and it is just humidity can affect the chances of you getting sick, not that lower humidity means you will get sick more
gusten765 holy peeps indeed I didn't take that one into account. Silly me.
Please PLEASE do a video about the health and other effects of using ozone as an air purifier.
God that would be depressing!
I wonder if it has to do with how people get the cold weather sniffles. When it's cold enough and your nose starts to drip a little bit even if you aren't sick. Then people wipe it off with their fingers and touch other things that work together with what was already stated about people staying indoors more.
Thank goodness for this video... There are too many people that attribute getting sick to temperature exposure.
Hunter Bowman That's because there are too many reasons biologically why being cold for long periods of time and inhaling dry, cold air would make you way more prone to catching a virus.
If you lived in a small isolated village. Is it possible that people would never get sick with the common cold?
A pacific island would be better!!!
Umm yes of course it is possible.... The virus isnt just spread by human contact, it is just in the air and sitting on stuff. If any human has had any contact with another object a human has touched, including other people, they have a chance to spread the disease. if your mother got sick and touched the wall. That wall has been infected and later it could be swept by the air and "become live again" to infect some one else.
I know that sounds gross but that is basicly how it is
Finally, thank you so much for this!
I think the connection to drying out nose and throat lining makes sense. When I bike to class during the winter and breathe in cold air I almost ALWAYS get sick (whether that's viral, allergy related, or otherwise I can't say, but its always the same symptoms. Headache, congestion, fatigue)
Here are a couple relevant facts that you left out. In other languages, the set of symptoms that we _associate_ with one of the more than 200 viruses responsible for the Common Cold and the word that we associate with a lack of heat, though they have the same label in _English,_ are not translated the same. In Spanish-speaking countries, they have no tendency to connect these notions. The only reason _we_ do is that they wear the same label, and the only reason they wear the same label is that we _give_ them the same label.
In ages past, colds had more of a tendency to spread when it was cold _only_ because, when it was cold, people had more of a tendency to huddle _in groups._ Unfortunately, people with the Common Cold are contagious _long_ before they are symptomatic.
"Wash your hand with soap"
I already do that regularly, my job requires it
"Don't touch your face with unwashed hands"
That's like the second thing I was taught at my job
"Stay away from people you know are infected"
My job is at a nursing home, so I physically cannot do that
Well, 2 out of 3 is fine I guess
after 30+ years I finally know catching a cold is not from feeling cold. I always thought how come a couple of degrees difference in temperature will cause me to catch a cold... but that's what my mom's been telling me since birth.
2:37 me when my blocked nose opens up after a long time!
Very good video and I agree with the points you made. Cold weather can stress the immune system, dry air is a factor as is more people staying inside for longer periods of time. It not just one factor, as I noted earlier, but is multi factorial.
As an Australian, I have to say, colds happen more in Summer.
I was always confused about that as a kid.
We're also not told to go out in the cold in Winter at all.
The dry air thing does work though. While yes, where I live in Australia, Summer is the wet season, airconditioning is a must for most people, and they will stay in airconned places, such as shopping centres with hundreds (sometimes thousands) of other people, and in their own homes (which aircons dehydrate). In Australia, it feels like being outside will kill you in Summer.
So it's purely a Northern-Hemisphere thing to think colds only happen when it's cold, because we down here in Australia get it at the same time as you guys, probably from all your tourists infecting us.
Man can never be hot
Thank you. 🌹
It's like -25 Fahrenheit here in Montreal>> you would catch a cold and more!
Because where I work is basicly it's own town (up to 10k ppl), I've been sick 3 times in 4 months. U just keep working.
What are the odds???
Who else has or recently had a cold???
I haven’t got a cold it’s just a runny nose!
An artist theory on the physics of 'Time' as a physical process. Quantum Atom Theory but a runny nose 24/7 is a sign for an infection, isn't it? But it could also be caused by the dry air inside caused by the heating I guess...
Actually, I've had a runny nose all year, so... maybe I'm a bad example after all =|
That profile pic matches this that post so much!
"143,245 views" I'd say that makes the odds extremely high that there will be several people who recently had a cold would also have watched this video. Also people who have recently had a cold might also be more inclined to click a video called "Why Do We Get Colds When It's Cold?" =)
I have one right now.
Thank you for the video! I really appreciate it!
Make sure you get rid of all the soap on your hands though. And use hand cream afterwards. Reason: when your skin gets dry (because of soap for example) it can't fight off microbes as well.
I also suspect the another wait people change their behavior in cold weather is affecting how many colds we get during the winter season. My nose tends to run a lot more when I go out and come in from the cold and I suspect most people's do. After touching a doorknob or other object infected with the cold virus you then might subconsciously wipe your nose with your hand and voila and infection.
HELL YEAH! This is real myth-busting!
Another thing: dry throat, runny nose, sneezing? Those are symptoms of catching a cold, but also of being exposed to cold, dry air. Is it possible that sometimes we confuse that for just "catching a really mild cold"? And that that's where the old wives' tale came from?
1. STRESS: Does stress lower your immune system? Then can being painfully cold for an hour, or more, give you stress?
2.CHILLS: Also what about when someone gets chills, and if someone gets chills that stays with them even after they return to the warm indoors, does that affect the immune system?
Something i noticed while in high school was that people actually got colds more often during the summer than the winter. During the winter they wore warm clothing and then went into warm class rooms. However, during the summer they wore cooler clothing outside where it would be 80's to 90's and went into 60 degree classrooms in that cooler clothing. My hypothesis was that the constant change in temperature may have negatively effected their cold defense.
no
In some parts of the world people also travel more during winter or are in malls more which means you're around more people, increasing your likelihood of getting a cold.
I have a cold since last night and headache too
I knew it, it's all about the inmune system.
One of my friends gets sick easily and usually wears a lot of things in winter to protect himself from the waeather; but then i go Training in parks wearing just shorts and t-shirts with short sleeves and i'm completely Fine (once i did this at 0 C).
I think when it cold people tend to stay indoors more near other people thus more likely to catch their illnesses.
Great hypothesis, why don't you watch the video and find out?
I have to show this to my parents and my in-laws! Unfortunately I don't think they would believe it.
We don't get sick with real cold like a dry -30 Celcius.
The worst is when the weather is transitioning from warm to kind of cold, the snow is getting wet, all the adolescent continue using running shoe to look cool and other summer clothes. The kids spread their germ in that virus factory called school.
Adult fee,l depressed, eat less or go to the virus factory for adult. The bad mood make us sleep less. Our body loss energy shivering and not enough remain for the immune system.
Sorry but I question those studies. How long did they keep the subjects in a cold room before testing immune response? It may take days or weeks of cold weather to have a noticeable effect on immune function.
Well they were in a cold room, it doesn't mean they were forced into a white cold prison cell for 2 weeks. The subjects probably signed up to help a study requiring you to stay in a cold room for a bit, while they sleep they would definitely have beds with heavy blankets, they would probably have stuff to pass time and maybe exercise. They were just studying the chances of getting sick in a cold environment, so if they spent most of the time in the cold they would be helping. Also since the study would be voluntary they can ask to leave anytime
It kinda irritates me that a lot of people think that a "controlled study" just means they take people throw them in a room with something and wait for a response
Agpiplup Exactly my point. It doesn't simulate the effects of living in a cold climate for weeks at a time. Unless they did a double blind study of populations in different climates or seasons it really doesn't work
no just no.
Ive had the worse cold lately,Be glad when its long gone
If you have a cold then you feel a lot worse if you are cold, than if you're warm. If I have a cold, especially one that isn't so bad, I'm more likely to still go out and do things if it's nice and warm than if I have to go shovel snow first.
Exactly at perfect time in my recommendation.
on chilly days, i contracted the flu after bathing with an open window. And I can kinda tell I would be catching a cold due to the increased sneezing.
Does anybody with long hair ever feel like their hair is frozen which makes your ears really freakin hot for some reason?!
I regularly freeze my longer hair while soaking in winter and I never noticed that. Aint the human body wonderful?
I got sick this winter vacation so when i saw this i was like, hey: i can relate.
The thing is that still in 2021 we don’t really know the exact cause and how to be 💯 immune to the common cold. What a shame. Let’s keep spending money on weapons. Thanks man. Great video 🙏
I once got a cold in summer. The weather was in the 80s to 90s farenheit (20s to 30s) celsius. Actually, cold air can hold just as much water as warm air, depending on barometric pressure. How else do you think the Sierra Nevada get snowfalls of 15 feet (4.6 meters)?
I have a thought that colds and flu may be more prevalent during cold months for a couple reasons, one many people eat more calories during winter months and often foods higher in sugar resulting in a slightly weakened immune system for some people. The other thought is that we all might carry viruses that are not active somewhere in our bodies just waiting for the immune system to become less efficient. Poorer diet and reduced sunlight could be impacting immune systems allowing viruses to take hold more easily in winter months. Add that too reduced physical activity for some people as a result of weather and some people exposed to viruses are possibly more likely to get sick.
Wondering also if viral particles that sit on surfaces survive intact for longer periods of time outdoors or indoors compared to warmer times. Viruses generally deteriorate on surfaces over time so wondering how much temperature and humidity might impact that.
tbh i only get small colds during autumn/winter, it's during the summer i get really sick. which is terrible because when you have a fever in summer heat which sucks
huh. I always thought it was simply because of the temperature of the cold air that is being breathed in mixing with the warmth of the body makes the temperature perfect for infections to grow.
Didn't they already have a video on this exact topic before
Vitamin D. Notice that we were told to start home in sars-cov-2 pandemic and not encouraged to boost up on vitamins & minerals. Ever.
Is there a relation between sudden change in the surrounding environement and catching cold ?
(taking a hot shower and going out in freezing weather)
I do not get the humidity dependency. Maybe the abs. humidity is smaller but the relative is higher in winter in Europe where winter is cold.
they better be paying those volunteers some bank for that test hahahaha
Here I am, watching this while sick.
And there is the fact that the immune system works better around a certain temperature... The reason why fever is actually helping the immune system by providing the right temperature for the enzymes to do their job!
And there is the fact that cold temperatures can cause rhinitis, dry skin and can damage capillaries. A damaged epithelium is more permeable to infectious agents...
And there is also the fact that we are less active during the winter... The lymphatic system requires some level of physical activity to be optimal.
The optimal temperature for the immune system is around 39ºC. This is equivalent to a "normal fever"... The main danger of fever is actually dehydration.
This is a graph of enzymatic activity versus temperature:
www.bbc.co.uk/schools/gcsebitesize/science/add_edexcel/cells/enzymesrev2.shtml
AND maybe there are just more allergens in the dry air that give us cold-like symptoms like generating more mucus?
I was kinda right. I had a conversation about this at work and i said it probably had something to do with cold viruses being able to transfer easier in the cold.
My first thought was the some bacteria that we have slows down its metabolism and becomes so slow it can't prevent the pathogens that enters us
Some people say it's a myth that you 'catch' a cold when it's cold, they obviously haven't met me. As soon as a cold draft catches my ankles I start sneezing and coughing and will have buckets of mucus for days. I either have a permanent condition that gets triggered by cold, or I singlehandedly debunk the myth :P
Could an episode be made about whether or not you should lather soap with wet hands or dry hands?
2:38 my favorite!!!!! 😍😂😂
Me too!
Getting Colds Is for the weak
IPLAYRANDOMGAMEZ not muscle hank, sucker
IPLAYRANDOMGAMEZ You simpleton could not possibly understand the great endurence of Muscle Hank
IPLAYRANDOMGAMEZ you really just don't get it. Muscle Hank is just too big and stronk to get cold. He's so muscly he'd prob just punch any cold away. If you were even a fraction as powerful as muscle hank, you'd understand, but sadly it appears your muscles are small and insignificant.
blizzard459 sorry to break the chain but are you immune to sarcasm by any chance? Or a just a troll?
Muscle Hank I want Hank to react to this account
