Matthew Walker Busts Sleep Myths | Why We Sleep

[@almostmatt1tas]

EVERYONE should read Why We Sleep. Incredible book.

[@CarlosfVilchez]

I totally agree :)

MattFlower amazing book, could be one of the most important books ever written ?

[@daegudude1048]

The only problem is that you get obsessed with having an sleep

[@HookBeak_66]

Back in 1988 I was led on a west coast beach, the sand was beautiful, the rocky coastline had a blow hole formation, and the gentle sound of waves sent me to sleep. This moment is almost etched in memory, I can certainly say its the most peaceful, restful sleep I've ever had. Professor Mathew Walker mentioned the sound of waves in his presentation, which made me think & type this comment.

[@prithviraj1080]

This book is gold. I find that white noise helps me clear up my head and eliminate any other sounds that might disturb sleep. That is why I use it but keeping technology far away during sleep is the best way to probably get sleep.

[@birdhovno]

This book is crap. He only scares people - if you dont sleep well, you die. Yeah that really helps.

I visualise. First I steady my breathing, close my eyes and get comfy. Then I visualise my self going on a vacation, I go to a stunning first floor apartment by the sea, I hear the sea. I have comfort food and good wine and visualise myself eating and drinking, candles are alight and there is a log fire, as it's winter... I drift away......... ❤️

Usually when i try to count sheep it'll always end like: "1 Sheep, 2 Sheep, 3 Sheep, 4 sheep, 5 sheep, 6 sheep, 7th sheep, 8 sheeps has jumped over the fence, 9 shee... Wait, if the sheeps can jump over the fence then the fence is totally useless, hmm... What if the fence was higher? And.... You know what? Lets just make a Wall instead.. Or a Metal Wall so that the sheeps can't jump over, Metal? Hmmm what if the Sheeps are actually made out of Metal, a roBOT SHEEP!!! hmm...but then they'll be able to jump over the wall, but what if we electricuted the Metal wall so that they won't escape..." And by this point I should be sleeping.

[@airevacrn]

Following a car crash, I either stopped dreaming or was unable to remember them. I used to eat a load of cheese, hoping to bring on nightmares but nothing. Dreams have come back, since, not as many but I now visit dreamland again.

[@renatabundz4807]

Dr Walker, I AM absolutely in love with you. You are so knowledgsble, clear and gentle

[@ProfessionalReferences]

I think most of it depends on the person.. --Counting sheep: Its one type of meditation so its good for ppl who have hard time relaxing the mind.. if you can stop your mind from going crazy of course you dont need it.. --White noise: If you're trying to sleep in a quiet place you dont need it but if there're some noises around i use it to stop focusing them too much.

[@Spooglecraft]

Interesting questions, here is my take on it. I should clarify first: I am a polyphasic sleeper and currently on an Everyman-3-extended schedule, meaning I sleep 4h30 at night and take 3 20min naps per day. Now, for the questions: 1) Keeping your brain focused on one single thing can actually help you fall asleep by greatly reducing the danger of your mind wandering off. Counting sheep may not be the best method, though. I've been successful with repeating a sequence of words or a short song in my head over and over until I fall asleep. 2) Eating before sleep is not recommended. Before naps, you shouldn't eat anything 30min-1h before and leave 2h-3h after a big meal. Whether eating cheese 1h before your nap does anything for your dreams is not known. 3) Coloured noise may indeed help with sleep. I am not very experienced in that area, which is why I do not wish to speculate on how or why, so I do not spread misinformation. 4) Naps can be very beneficial and are an essential part of many polyphasic schedules. What Mr. Walker is hinting at is the effect, that light sleep (NREM2) seems to act as a sort of wakefulness sustainer. Futhermore, on harder schedules, which reduce the core so much, that it cannot fit SWS and REM needs, naps will, after adaptation, provide that missing deep sleep. 5) Yes, that is what polyphasic sleeping is all about. Not only is the Siesta being practiced in certain parts of the world, evidence points to pre-industrial humans practicing Segmented sleep, which consists of 2 3-3h30 cores at night with a wake gap in between. Some people are naturally Segmented. If you tend to wake in the middle of your Monophasic core, you may be one of them. Now, there is a lot more information. One of the best tips I can give right off the bat is to sleep at consistent times. Your body will become accustomed to those times, which can help with sleep onset and sleep quality. Also, it adds structure to your day. Another great tip is implementing a dark period. That is an 8-10h period of time in which you avoid blue and green light. This is important for your circadian rhythm, as light is the most important Zeitgeber. Furthermore, you should not eat or perform heavy exercise during the dark period. This period stimulates the release of melatonin, a hormone, which is needed to go into deep sleep. You start your dark period 2h before your core sleep, time sleeping is counted as part of the dark period. To implement the dark period, red laser glasses are recommended, as they are the most effective at blocking out harmful wavelengths. There is still much more information, which you can find on polyphasic.net/ Also visit our Discord server to get help in improving your sleep quality.

[@Ryan-qn1wr]

What's the point of the 20 minute naps, why not just do one two hour chunk in the day? Is that just how your body sleeps, or did you choose it?

[@katyantis]

I think you missed one point of the noise machines, the only reason I use one. It cuts out the background noises. Cats playing, storm comes, air conditioner kicking on, person next to you snoring, etc... this way you have a constant noise vs super quiet with a burst of noise off and on during the night that wakes you up.

[@wilfredv1930]

Excellent advice on naps!! I used to take naps even when I have sleep issues

[@shayneedwards8018]

I really like where he talks about listening to white noise. Listening to sounds of rain on my phone doesn't do the trick. But being raised on a farm half my life, actual real rain, rumbling thunder, and wind knocks me completely out because I can actually "feel" it.

[@deepriver4389]

Intentionally depriving someone of sleep is a form of torture. Sleep Deprivation Torture has been used to cause harm.

[@Ray-zj4wf]

actually Why we sleep abstracts some great points. It introduces many terms, REM sleep, nREM sleep in the nREM sleep, it can be also cleaved as 2 kinds of sleep which are Deep and Light. So now you have 3 types of sleep, Deep, Light and REM sleep(Rapid Eye Movement) in one sleep cycle which is 90 minutes and in terms of a 7-9 hrs of sleeping, you get a rough 5 or even 6 cycles. Those 3 sleep systems play different role and they are consisted of different RATIO in every single cycle. basically you get the most DEEP sleep at the beginning of the 5 cycles, then less and less for each cycle passed. LIGHT sleep always included the DEEP sleep which make sense coz you go from LIGHT to DEEP and end with LIGHT then WAKE UP REM sleep always proposed between each cycle and in the last cycle, huge amount of REM sleep contained. DEEP sleep functions like you put your temporary info from your hippocampus to be permanent. LIGHT sleep functions as cleaning your email rooms, or in other words, your temporary room during the whole day on REM sleep allows your mind to make sense of what happened during your day to make connection between them with previously stored info. So those 3 types work collaboratively and it cant be broken down. Hope it helps

[@rosyybear]

the last part was a bit confusing because in the book he says we need to sleep 7-9 hours and not half like he stated in the video

[@stevekirkbride1723]

Thank you Matthew and Penguin books for a great informative video

[@MultiMobCast]

Great video, the only thing I was left with questions about was napping and biphasic sleep. If I understood you correctly, there seems to be a bit of a contradiction here.

Hi Matthew, I d like some comments on what if I have a newborn baby, who wakes up at nights for 2-3×1 hour. Somehow human always had to get used to that right? So now I sleep like from 21pm to 6-7am with some interruptions.

Yes counting sheep helps to sleep Eating cheese would increase glutamate and could have some affect possibke to bightmares or finding harder to sleep. But milk helps.

For my summer job I am going to work in shifts. It’s six weeks and it consists of 6 days with 2 shifts of 6:30am-2:30pm, 2 shifts of 2:30am-10:30pm and 2 shifts of 10:30pm-06:30am. After that 4 days off and then again the same shifts. After that I will quickly go back to forex trading and sleeping consistently and 8 hours a night. I am just wondering if sleeping during the day helps a bit for your body (I know it won’t do anything good to the circadium rithym.)

[@hno0onh979]

In my own opinion white noises makes you think you're in that situation of rain, heart beats without looking at them and therefore you feel more relaxed and sleep, also i mostly use it to leave my phone at night and sleep haha And for napping i utterly hate them, i get bad dreams and i wake up more tired than i was so I'd rather meditate instead

Welp spicy food increases your internal body temperature..

[@housamlefrif7719]

counting sheep and hearing white noise or ocean noise, i think its the fact that you let your mind free and watch it work, that fact itself distance you from yourself and put you in the backseat, while your brain is driving, maybe the reason of counting sheep does not work is that you actually are still in the driver seat still thinking manually, hearing white noise or ocean noise can let our imagination run wild like watching a movie, that can always put us to sleep faster if we don't feel invested in the movie, so maybe if we want to sleep faster, all we have to do is lay down close our eyes and tell our mind take me on a trip, watch but put emotions so you don't get invested and have to manually think ahead, let your brain tell the story while you listen. just a maybe i dont know

So ... don’t nap, but sleep biphasically? Isn’t that conflicting advice?

[@walkerneo]

If I understand correctly, I believe he's saying that there's reason to believe biphasic sleep could be as good or better for us, but if we can't get the second sleep in consistently, then we risk disrupting the primary sleep at night

[@mohammadhuzaifa7]

What he means by that is, most people sleep monophasically meaning they sleep for 8 hour continuously. However, there is a psychological drop in out attention between 2pm to 4:30pm, we are not designed to sleep mono phasically. If you nap before 3pm there shouldn't be a problem but napping close to bed time may disrupt your sleep cycle and make it harder for you to fall asleep.
