Good to know that you can vouch for what he says. Can I ask, what exactly was it that let you recognize that he know what he's talking about in this talk? Or have you looked at his other stuff?
Interesting thing was that when Matt asked if people currently got young children, I saw 6 people(when pausing) raised their hand, he surmised that to be quite a lot. One aspect, though maybe minor, surround decreasing child births are related to this. Most of them seemed like they were at an age where people normally had children.
How much have diet books helped people get slim, Obesity is on the rise. Books almost never help. They help only those who know the stuff and are practicing those things and actually dont need the books. The sales of books are driven by those who just buy and shelf the books and never read and even if they do read NO ONE actually follows the advice. People dont succeed with changes more than 2-3% of the times . Books and TED talks etc. never change behaviours

This is perhaps one of the most important talks at Google yet. Until you get sleep right, nothing else is going to work as well as it could. Thank you for being a true sleep representative Matthew Walker.
My sister diagnosed with early onset Dementia. I truly believe she got it was because she has never been a good sleeper. She has always tried to live on less than 4 hours of sleep. Everyone says that driving while drowsy is more dangerous than driving while intoxicated. Your body--more importantly-your brain is healed while you sleep. Not enough sleep is really, really dangerous.
20 minutes - We don’t look at babies sleep patterns and say “Psst, what a lazy baby?!” Lol. Excellent point. Mr Walker & his book may have saved or extended my life. Thank you
And especially more in the case of adult life when we have much bigger bodies who consume energy and also work all day back-to-back its necessary to sleep much(enough) and even some naps.
The way he presents a concept reminds me of the physicist Richard Feynman. Mr Walker could explain sleep to a child and make it interesting and digestible. I'm kind of hooked!
As I get older I find I don’t sleep much. I’ve tried various things to get to sleep, or to get back to sleep when I wake up after an hour or two. What works surprises me more than anyone else. Eg watching videos on RUclips, having a cup of coffee, having something to eat, reading, etc. with me everything seems to work backwards. I’ve just decided to not worry about it.
I experienced sleep at the wheel when I thought I was perfectly fine... I had never had an accident before in my life and I love driving, have driven cross borders for days.... this was just a 1 hour or so drive after work, I was more in shock that I actually fell asleep than the actual accident because my brain recreated the visual of driving... it was like I had a small dream of the reality of driving... the vibrations of the front of the car grinding into the central reservation + pure luck is what saved my life. I will never allow myself to even get to yawning stage. Stay safe people.
I just wanted to let you know that my mom repetitively recommended this to me like it was the best thing she ever listened to. You are very persuasive!
I imagine your mum is worried you don't get enough sleep :-D People engage in so many things to improve their health, yet most ignore the importance of sleep. Given that sleep is possibly the most important overall health factor, it's a sad state of affairs.

@@sleepsmartsmashstress740 you just love to put this author and book down, don't you? What he is saying is both logically consistent, lines up well with the latest in neuroscience research, and fits with my own personal experience. What counter examples do you offer?
I first heard of the book here, and I'm glad I did. Since I've bought it I have completely changed my sleeping habits and I have already felt the many benefits described in the book. Read this book. It should be required reading for every high school aged student.
Thank you very much Matthew for wonderful insight on "Sleep"; why do we need goodnight sleep, and the consequences of deprived sleeps, how to cultivate the habit of sleeping on right time, preparedness before going to bed, the impact of alcoholic and caffeine on deep sleeps, model of prevention rather than curation, medication for snoring diseases, all these criteria of sleep has been explained well. I strongly recommend people to buy book " why we sleep", and understand the importance and essential to have good and deep sleep. Good night..Sleep well, have 8 hours sleep, dream well and never deprive from sleep, it's free Gift and you need not pay, but lack of sleep will result in incurring payment for medical assistance. ... Stop sleeping more on weekend...
My only question is whether regular sleep patterns and proper sleep health can be achieved in an industrialized society that demands more from a person than they can give. Great talk! I’m definitely going to read up on this book he made.
@@jimsbooksreadingandstuff Very important! Bright light and or sunshine in the early morning when you wake. And darkness in the early evening to prepare the body/mind/brain to sleep. Take melatonin 1 or 2 hrs before you want to sleep and dim the lights, avoid screens then. Good night! 😴
To Know what a important thing is sleep make me more nervous and anxious about the duty with respect my health for do not fail my rest and therefore made me sleep worse
I almost ran into a vehicular accident due to lack of sleep. I was a riding a motorcycle and I was very sleepy. I thought that I momentarily closed my eyes but in reality, I fell asleep. Luckily for me, I ran into a pothole and was awakened. When I opened my eyes, I was already on the opposite lane in front of a car with the driver angrily honking his horn at me. I never drove when I'm sleepy since then.
People at my work pride themselves for attending global meetings at 2am. I actually had to turn down a 1am meeting and got a talking to from my boss because I am salary. This guy does a great job talking about sleep, I am pretty sure we were never supposed to work 40-50 hours a week then go home and work another 10hrs on the house during the weekends, we have been duped.
I find the bit about late chronotypes interesting - if people, who are naturally late sleepers, are not "insomniacs", how can they balance a good night's sleep with the need to go to school/work at 8/9 AM? It's a bit of a shame that there wasn't a follow up question about it.
The bit about micro sleep while at the wheel was very scary... that's why i have decided to make a change in my lifestyle and got a car that can automatically hold the lane for me. now i can sleep behind the wheel all i want! yay 🥳
Hopefully none of these people will be fired when listening to the advice given to the question at 46:45 and he omits the fact that society does not really have room for chrono types. This talk is mainly about managing the natural instincts we have surrounding sleep to fit our society. Mainly because there's little room for natural instincts when you are trying to fit a schedule and deadlines.
This was so informative - thank you! I especially found the bit about REM sleep disorder interesting as my dad was diagnosed with Parkinson's a few years ago. Definitely showing this to him. Thanks!
Great talk and I look forward to read Dr. Walker's book. As for using sleep metrics to predict health, this is an interesting model on so many levels and I really hope it'll work out.
I love Matt Walker. He is a great advocate for sleep, with wonderful first sentences.. He is brilliant on the problems of sleep. On solutions, I want him to know about us. because I think we could transform sleep when our brains have forgotten how to sleep well.
My experience is depending of what i have lived in the day, the amount of sleep i need as well as the quality of sleep (the different phases) can be very different. So what my mind experienced within the day is what my brain has to sleep on during the following night. May I generalize that it is the case for everybody..
I am addicted to the internet at bedtime . I feel like I’m missing out if I can’t go down rabbit holes from 10 pm til 1 or 2 in the morning . My excuse is that I work from home and don’t have to get up til 8 am . But I know this is a bad habit and to much chaos for my nervous system that late at night . Can anyone else relate ?
What he said is actually very true. My apple watch tells me if I drink coffee in the morning at around 8 am, my heart rate will increase at the same night even when I am sleeping. I never realised this until I monitor my heart rate.
Great talk ! Really opened my eyes. Most of the times, I do sleep extremely well when I am traveling in a bus or train or in a car ( as a passenger), it is the most refreshing nap 😊 why is that ?
I've had the same experience, it's even better when it's raining. It just feels cozy. The cool thing is, you can find recreations of the sounds on RUclips now.
Suggestion that a key part of the need for sleep is the body's need to make serotonin, which it does in a symbiotic relationship with gut bacteria in the large intestine. We sleep to first produce serotonin, then to draw it into the body through the extraction of water in the large intestine. Though it can be synthesized, there seems to be a major difference in the health benefits from the micro made serotonin, and the artificially made serotonin. Here's some notes on both how important serotonin is and how widespread it is in all living things. Besides mammals, serotonin is found in all bilateral animals including worms and insects,[19] as well as in fungi and in plants.[20] Serotonin's presence in insect venoms and plant spines serves to cause pain, which is a side-effect of serotonin injection.[21][22] Serotonin is produced by pathogenic amoebae, and its effect in the human gut is diarrhea.[23] Its widespread presence in many seeds and fruits may serve to stimulate the digestive tract into expelling the seeds.[24] Gut bacteria manufacture about 95 percent of the body's supply of serotonin, which influences both mood and GI activity.
The medical industrial complex's failure to properly research and diagnose and treat microbiome and sleep and vital nutritional deficiency issues (including those related to Vitamin D3 and Vitamin K2 and Magnesium deficiencies as well as iatrogenic prescription medication usage) is a major reason why psychiatric iatrogenesis is a primary contributor to the third leading cause of death in the U.S. (which is iatrogenesis in general). If the U.S. spent just a fraction of the over $40 billion each year it spends just on iatrogenic psychiatric drugs alone, on properly researching the issues discussed in this and related RUclips presentations we would probably, Lord willing, achieve an absolute revolution in medical efficacy improvement and iatrogenesis reduction.

Curious about this 8hr sweet spot that doesn’t seem to chime with the understanding of circadian rhythm... fascinating subject I want to keep learning more about so I’m happy to read others opinions.
The only time you pull an all nighter really is when you are lacking to properly cover all the material if you would go to sleep and only covered about 70% of the material properly it would be more beneficial to carry on and finish all the work to 100% and and take off roughly 40% from each question asked in the exam you would end up doing better because the chances of getting 0% for a question that would be asked in the 30% that you did not study for is very high, Ceteris Paribus.
so the bit where he mentions that your brain paralysis you when you go into REM sleep, I and many others have encountered this and we see it in a negative way because we sometimes experience some type of hallucinations. it would be commonly referred to as sleep paralysis. Does the fact that you begin to dream in that same state where you become paralyzed have anything to do with those experiences/hallucinations?
I have never slept well since I was 12 now I am 43. I always had bad dreams haunting me every night. I think it is anxiety. and it started to take its toll on me badly I felt as if i ahd alzimer I felt very bad waking up as if i didnit sleep at all So suffering
Napping not after 4 pm can help some people by keeping it less than 30 minutes. You can never waste time sleeping if you are not just tossing around in the bed. Actual sleep is always beneficial
Hi Matthew- I really love your sessions and although I’ve been to sleep clinics and sleep specialists, I have learnt so much more from listening to you. I have a challenge for you ............... I am a chronic insomniac and have been since I was 12 years old ( boarding school ). I am now 59 and have battled with 2-3 hours of sleep each night when trying to doing it without sleeping pills. Without the pills has been unbearable as I feel sick from tiredness during the following day. I am presently working in China and and may give Traditional Chinese Medicine a go, however I am quietly pessimistic. Can you help!
Anne Champion I had insomnia since preteens and now 52 sleeping the best ever. Balancing the body chemistry with diet, supplements, detoxing heavy metals and practicing all mentioned sleep hygiene in this video. Also, balancing sex hormones. It has taken a few years of commitment but so worth it.
Examples like yours always make me thing that human biology is so amazing. People are able to live their lives even on decades of terrible sleep or diet.
What I wonder is why I feel more tired/sluggish in the morning after 8-9 hours sleep than after 5-6 hours (I tend to have a lot more energy in the morning after 5-6 hours sleep, which affects workouts for instance). I've been watching a lot of Matthew Walker videos to get a handle on this but he never talks about it.
I’ve heard him say regarding this that you may be chronically sleep deprived...you may need multiple days of 8-9hrs of sleep in a row to get back into full energy
Additionally it also matters when you wake up in your sleep cycle. It's actually easier to have a complete sleep cycle and wake up, than have a sleep cycle, start another one, then have to wake up from deep sleep. That's why some nights if I have to get less than 3 hours it's sometimes easier just to say up. So yeah, I would suggest looking at your sleep cycle and carcadian rhythm Sleep is so important though, I really feel the difference after a few days of sleep deprivation. Also as a side note (this is more Chinese medicine stuff) but sometimes when we are well rested, we have more energy , but this energy shows up in unhealthy ways, like angst or something, so being depleted might feel better, but that's because as you get more energy we actually need to work through our issues for that energy to become balanced. Anyway, Peace
I suspect the reason why so many tech people are very child like and niave in their behaviour/beliefs (infantilization) is that they are sleep deprived and aren't capable of supressing REM behaviour in the real world.
@Lottie J I'm a software engineer and I've noticed how child like my environment and many of my co-workers are. Don't get me wrong I like them but I could see they could do with growing up. Other professionals types, Laweys, Accoutants etc.. don't have arrested development issues and aspire to adult environments. Why is the tech industry different? I might be wrong about the cause - but it'a a real problem.

The medical industrial complex's failure to properly research and diagnose and treat microbiome and sleep and vital nutritional deficiency issues (including those related to Vitamin D3 and Vitamin K2 and Magnesium deficiencies as well as iatrogenic prescription medication usage) is a major reason why psychiatric iatrogenesis is a primary contributor to the third leading cause of death in the U.S. (which is iatrogenesis in general). If the U.S. spent just a fraction of the over $40 billion each year it spends just on iatrogenic psychiatric drugs alone, on properly researching the issues discussed in this and related RUclips presentations we would probably, Lord willing, achieve an absolute revolution in medical efficacy improvement and iatrogenesis reduction.

Thanks for interesting and useful information
This is absolutely profound
discovered the guy yesterday, and slept till three in the afternoon today.
things this guy know god damn. the more you keep him talking, more new important things he says.
Curious about this 8hr sweet spot that doesn’t seem to chime with the understanding of circadian rhythm... fascinating subject I want to keep learning more about so I’m happy to read others opinions.
Matthew Walker's MasterClass is outstanding. If you care about your health and longevity, watch it!
watching it as well, really good!
What a beautiful view
brilliant information thank you Mathew
Watching this at 2 am. Time for Bed !
Superb content. Great audio. Thank you.
I can fall into deep sleep 4 hours after having a cup of INSTANT coffee. Starbucks coffee on the other hand or energy drinks would disturb my sleep.
I like David eaglammans theory he say we dream to stop other parts of d brain from taking over it makes lot of sense when u understand d brain
Am I the only one losing sleep watching Matthew Walker videos??
The only time you pull an all nighter really is when you are lacking to properly cover all the material if you would go to sleep and only covered about 70% of the material properly it would be more beneficial to carry on and finish all the work to 100% and and take off roughly 40% from each question asked in the exam you would end up doing better because the chances of getting 0% for a question that would be asked in the 30% that you did not study for is very high, Ceteris Paribus.
Out standing
Incredible interview! Thank you!
this guy is incredible great content
This guy is right! ( @ 91, take his advice before it is too late) !
I prefer the rule, "If the last thing you touch at night is your phone and not your partner, you are in trouble."
so the bit where he mentions that your brain paralysis you when you go into REM sleep, I and many others have encountered this and we see it in a negative way because we sometimes experience some type of hallucinations. it would be commonly referred to as sleep paralysis. Does the fact that you begin to dream in that same state where you become paralyzed have anything to do with those experiences/hallucinations?
I have never slept well since I was 12 now I am 43. I always had bad dreams haunting me every night. I think it is anxiety. and it started to take its toll on me badly I felt as if i ahd alzimer I felt very bad waking up as if i didnit sleep at all
So suffering
must be nice to get by with 9hrs of sleep a night. I sleep between 10-11 with at least an hour nap during the day or evening
What about daily Naps.
Do they help or are they a waste of time?
Napping not after 4 pm can help some people by keeping it less than 30 minutes. You can never waste time sleeping if you are not just tossing around in the bed. Actual sleep is always beneficial
He says that if you are not strugling with sleeping at night, great
I've never been so excited about sleeping
Hi Matthew- I really love your sessions and although I’ve been to sleep clinics and sleep specialists, I have learnt so much more from listening to you. I have a challenge for you ............... I am a chronic insomniac and have been since I was 12 years old ( boarding school ). I am now 59 and have battled with 2-3 hours of sleep each night when trying to doing it without sleeping pills. Without the pills has been unbearable as I feel sick from tiredness during the following day. I am presently working in China and and may give Traditional Chinese Medicine a go, however I am quietly pessimistic. Can you help!
Anne Champion I had insomnia since preteens and now 52 sleeping the best ever. Balancing the body chemistry with diet, supplements, detoxing heavy metals and practicing all mentioned sleep hygiene in this video. Also, balancing sex hormones. It has taken a few years of commitment but so worth it.
Examples like yours always make me thing that human biology is so amazing. People are able to live their lives even on decades of terrible sleep or diet.
Most informative. Thank you!
What I wonder is why I feel more tired/sluggish in the morning after 8-9 hours sleep than after 5-6 hours (I tend to have a lot more energy in the morning after 5-6 hours sleep, which affects workouts for instance). I've been watching a lot of Matthew Walker videos to get a handle on this but he never talks about it.
I’ve heard him say regarding this that you may be chronically sleep deprived...you may need multiple days of 8-9hrs of sleep in a row to get back into full energy
Additionally it also matters when you wake up in your sleep cycle. It's actually easier to have a complete sleep cycle and wake up, than have a sleep cycle, start another one, then have to wake up from deep sleep. That's why some nights if I have to get less than 3 hours it's sometimes easier just to say up. So yeah, I would suggest looking at your sleep cycle and carcadian rhythm
Sleep is so important though, I really feel the difference after a few days of sleep deprivation.
Also as a side note (this is more Chinese medicine stuff) but sometimes when we are well rested, we have more energy
, but this energy shows up in unhealthy ways, like angst or something, so being depleted might feel better, but that's because as you get more energy we actually need to work through our issues for that energy to become balanced. Anyway, Peace
Maybe you are a lark, who needs to go to sleep at 9 pm, and wake up at 5 am having slept your full 8 h.
Amazing!🙌🏻🙌🏻🙌🏻🙏🏼🙏🏼🙌🏻
It's 4 AM when I'm watching this
Are you asking, uninterupted sleep? Does getting up to go to bathroom and then going back to bed falling asleep counts?
Excellent
thank you. that would explain a lot.
Since menopause started , i am not sleeping like before , i wake up tired , and i am aging quickly
Any advices !
Very Good!
I suspect the reason why so many tech people are very child like and niave in their behaviour/beliefs (infantilization) is that they are sleep deprived and aren't capable of supressing REM behaviour in the real world.
@Lottie J I'm a software engineer and I've noticed how child like my environment and many of my co-workers are. Don't get me wrong I like them but I could see they could do with growing up. Other professionals types, Laweys, Accoutants etc.. don't have arrested development issues and aspire to adult environments. Why is the tech industry different? I might be wrong about the cause - but it'a a real problem.
2-3 hours per night for the last 20+ years. Occasionally 4-5. Sometimes zero. It’s more like I rest at night rather than sleep.
how are you now?
My cat will clearly never get Alzheimer's Desease! I should learn from this!
