Why do we sleep? We spend a third of our lives in slumber, but science has yet to determine exactly why we have do it. Here’s a look at how sleep works, why we’re not getting enough sleep, what happens if you DON’T sleep, and an idea about where sleep came from in the first place.

Sleep is just like death but with advertisements.
"We have no idea what happens after we close our eyes" I do actually, I lay in bed for another 1/2 hours rethinking my entire life until I drift off to sleep and *then* I don't know what happens
Quickest way to fall asleep is turn every light off even a nightlight cause that light is tricking your brain in thinking it’s still dat time put away your phone id actually recommend turning on a you tube video a long one like an hours worth something can be anything and turn brightness down flip phone over so screen not making the room bright and turn sound down a bit and just lay there and listen with your eyes closed in the dark. This gives your brain something to listen too so your not laying there thinking about everything and within probably 15 minutes you’ll be asleep. This works for me every time
That's how I sleep! I get extremely sleepy at around 8-9pm, wake up at around midnight and then fall asleep again at 3 am. I thought i had a sleeping disorder, turns out I'm "default"
I'd default but I'd get my azz whooped
It happens because you go to bed to early. Go to sleep at midnight and you'll sleep 6 hours straight.
Me too
I always thought I was crazy because if I go to sleep before 10 my body just can not sleep straight through the night. It’s like a long nap and then I get up for hours and then finally go to sleep again. I guess that is just natural
@A B for real, I had an aneurysm reading that.
sleep is underrated. Luckily research is now showing how important sleep is and that stupid idea that sleeping is akin to laziness is being put in the trash bin where it belongs
So true. If anything hardwork is linked to sleep
@@criminalconcept7126 ya
Harsh but true
Asian parents are seething

I have a theory of my own. As mentioned in the video, we consolidate memories and clean our neurons during sleep. But I also think it's when we rest our tonic, or postural muscles. Our tonic muscles are always firing in alternating sequences while we are awake- it's how we stay standing or seated upright etc without any conscious effort. But those muscles need to rest and rebuild- sleep shuts them down so they can rejuvenate.
What about sleep walkers?
@@kathleencandelaria4106 What about them? They don't do it every night, or all night. The same things that happen when everyone else sleeps still take place for sleepwalkers. Good question though- thinking outside the box!
I have a very active mind and I think that's part of why my dreams are so dramatic and wild and I remember them very often. In some ways it's cool but it's also tiring too.

cutting down on coffee, to max 1 per day in the morning, improved my sleep sooo much. used to have days where I just lay awake in bed for hours. now I sleep in a few minutes and trough out the night.

@@user-cs6fl7zp8b Yeah, okay--insomnia, irresponsible parents, chorse, schoolwork, homework, projects, 8hrs basically wasted--education is important but it isn't an all day every day important thing. Maybe we should change the education system, study the things we want to study, maybe then students would pay attention and we would have professionals across all work places. 👍
Петър Жотев it takes 2 hours to get to school where I waste 7-8 hours to come home after another 2 hours to do 2-3 hours of homework. That’s not including chores and project/study time🙃
Петър Жотев are you a teenager in the US edu system?
My case is very different cuz I sleep in class and I got disturbed by classmates than the teacher
It's very good for mental health and eating too. Whenever I feel anxious and realize I'm not feeding well, I'd start adjusting my sleep schedule so that I go to bed early and wake up early. It just makes you function so much better and you feel healthier. After a few days, you get used to it and start loving it.
And now this is the last video I will be watching before I head off to sleep. Thanks for the explanations! I learned some new things today.
Why do I have to be at school at 7AM
I have actually read somewhere that teenagers' brains don't start working properly before 9 am so it's really bad to start learning so early when our brain can't even process it properly
@@vivientakacs5599 i have graduated recently and i concur, because sleep is often related to keeping memories you basically have a vicious cycle of sleeping, waking up, doing the work, sleeping, often not remembering anything in between, then you crammed for the test and forget everything on the test afterwords.
i may have graduated from high school but i don't remember at least 90% of what they taught me, heck raise that number to 99.6 percent of what they taught me, i only remember some algebra and the quadratic formula and i only remember the quadratic formula because of a parody.(this parody specifically: th-cam.com/video/VOXYMRcWbF8/w-d-xo.html )
ya, teachers are smart but the people they work with(the district, and to a greater extent the department of education) are dumb and really need to rethink their education system, I say we switch back to the putting all grades in one room system or at least try something and one more thing, get rid of the standardized tests, lets stop this one size fits all bullcrap.

It's not every night, but I'm very excited to go to bed every night for this reason. I can't wait to know what science continues to find in order to explain it all!

A wonderful question to answer at 12:57 in the morning.
Come on scientists! I don't want to waste 1/3rd of my life!
Well... tecnically your brain is still working at sleep, by dreaming, that counts as living, you just can't remember that 1/3rd part of your life.
Also, dreams tent to be much more interesting than actual awake life...
MarkusTegelane - Your welcome to do a "Don't sleep at night challange.
Or tho, I don't think you have much to do from 11 pm to 6-7 am, unless you live in a big city, or watching TH-cam.
SilencedFeelings I actually remember all my dreams
We waste 2.5/3
You are already wasting a lot of your life in doing stupid stuffs, why not waste it on sleep?
Hey there. Just to say, you definitely answered your own question! I work in cognitive neuroscience doing research, so you've definitely got my full attention with this video. We learned in our master's program that indeed we do know exactly what sleep is for, and you said it right at the start of the video! It's just to deal with all the adenosine build up leftover from the ATP used during the day! As adenosine rises we become drowsy, and when evolving over millions of years... being drowsy during hunting time kind of meant death! So as you said about balancing the alertness systems, it's best to make sure you time it right and have the time of alerting hormones during the day. The development of circadian rhythms as studied in ancestral organisms merely overlaps as secondary pressure for our body to sleep (as you set reset every day to sunlight to set oscillations for ~24hrs), so when circadian forces and metabolical forces (i.e. adenosine build-up) are exerted the strongest NET effect, then we best pass out right at that time so that we're ready to hunt in the morning! So to put it shortly, gotta get rid of that adenosine at some point, so may as well do it while there's no prey out for the catching! Or perhaps rather than hunt... be sufficiently awake to sit in our offices and watch funny gifs with clumsy cats.
+Joe Johnson Awesome comment, thanks! I hate declaring anything "case closed" but sounds like I could have worded this a little more wrapped up
So if there was an artificial way to remove the adenosine without sleeping we wouldn`t need to sleep anymore? i dont buy it. I think sleep is necessary for brain function, i think it decides what Information to keep and which to remove and other Information maintenance. like defragmenting a computer. removing adenosine seems very little.
Wow! You answered my comment haha awesome :D
You're totally right! Honestly tho that video is great, I find it awesome that you could pack so much in to just a few minutes, I don't know how you guys manage to be so comprehensive, well-researched, and clear in such short videos. Thanks really for all of them! And to @RoScFan, you can't remove adenosine, because it turns back in to ATP which you need to live, but you can use a magical little product COFFFEEEEEEEE haha yum yum yum, caffeine is a competitive inhibitor, since it can fit in to adenosine receptors. Unfortunately the adenosine just hangs out in the mean time building up... so once the coffee wears off then you're just as tired as you would have been before :( And regarding consolidating important thoughts and experiences, I might assume that could be a downstream evolutionary spandrel, possibly something that we learned to use sleep for once we previously developed sleep patterns for more primitive needs, in the mean time evolving to have larger brains which I would very well assume would need a break every day! ***Bear in mind I am using no sources here and am not claiming that is fact, just based on things I sort of remember hearing in lecture years ago, I could be wrong so please don't sue me***
Just a thought tho... I wonder how meditation plays a role in all of this... could it offset metabolic and circadian drives to sleep... could it account for the information maintenance? Hmm could it even propagate the metabolic functions that produce ATP??? I wonder :P Maybe a next video for that: "What does meditation do?"
Maybe someday we will have our adenosine extracted and only sleep for recreation. We already know how to command falling back asleep with melatonin
We could command our bodies sleep cycles, if we understood the receptors that they work by completely
Melatonin is also generally cheap, so even if we see light all the time you can still get to sleep normally
If whatever flushes adenosine was equally cheap it would change a lot of things in societies around the globe
here's a few suggestions for ways to treat insomnia
Try to lessen the noise when you are going to sleep
Drink a honey drink or eat honey
Find out the cause of your insomnia
(I discovered these and the reasons they work on Hartlyn Sleep System website )
Usually, I get so tired around 5 or 7 evenings that I go to sleep and wake up later. For evening events, like doing a gig or going out somewhere, I try to plan a good rest in the afternoon. This is the second time I hear that's it's kind of a natural pattern; before, I used to think not being able to stick to 16 hours of activity in one block and 8 hours sleep afterwards is something freaky, but I'm glad to learn it's actually a sign of good health.
I usually sleep in 2 parts and am up for a few hours in the middle of the night in between them. I used to think it was weird but I guess not
Who else will sleep for 10 hours and feel even more tired?
If you are not a teenager 10 hours might be a little long! try these 11 tips! specially the second last one and I am sure you will feel amazing

Nice defense of the DoE though. Way to be patriotic, bud.
@Allister . yeah no the Department if Education is terrible but you can’t blame it for a lack of sleep. More often than not, it’s used as a scapegoat so people don’t need to face the fact that they should work harder and better their life

Very mad that the video ended that fast… currently fighting sleep made me wanna learn more about sleep
From how I see it we all get 24hrs in a day
8 To rest
8 To work
8 For or selves
Yeah, except people spend 9 hours at work, plus 1 or 2 hours getting there and back. 2 hours running errands, cooking, eating, etc. Now you get 3 hours to yourself every night.
Yay
you're right, there's 24 hours in a day
Not really
Actually there is 23 hours 56 minutes
Can someone do the math for me

Going to rewatch now
I love to sleep. On off-days I automatically sleep between 9 -11 hrs. Surprisingly it is true, I often wake up after five hours, read a book or watch videos until I drift off to sleep again.
Working early or night shifts totally destroys my natural sleep pattern.
I love this channel!
He always tries to answer the questions that I've had always wondered but never asked!
Me trying to sleep:
"Alright, you got this, don't think about sleep..."

(I can't sleep when I'm thinking about sleeping)

Watching this on my 3rd day up in a row due to severe mental health 🙃 great. But honestly good video!!

3:22
"Do other stuff......"

I regret my life.
I have a hard time staying focus, but I can listen to this man talk for hours!
You are preaching to the choir on this one sleeping is something I don't mess around with. I heard about a sleep study that made it clear that sleep isn't something that you can catch up on like eating and drinking rather it is more like breathing.
0:20 lucky me I don’t need an alarm to wake up I have a built-in alarm in my head that wakes me up at the same exact time everyday
perfect video since I am taking a test about sleeping patterns in less than a hour, thanks!!!!
I'm 15 years old, and oh man 5 hours of sleep a night would KILL me. I am asleep by 10, and wake up at 6:30am. 8 and a half hours! And I still feel sleepy some mornings. I'd say, oh, I hate sleep, but the truth is when it comes 9:45 pm end of the day, I'm exhausted and need a break. Sleep is wonderful. Fellow 15 year olds out there, get some damn sleep!
i'm 14 and sleep from around 1am to 6am on weekdays and on weekends 2am to 11am
There are new studies that show that people need 8 or 10 hours of sleep is bullshit. You will sleep over the required hours of sleep which is 6, and go into another sleep cycle. That is why you are tired. Actually it depends on the person. Some people might need 6 or 8, but 10 is overkill. Just experiment.
almost 17 and I sleep at around 2am and wake up at 6:30
go to bed!! lol
Horrible man. You ok now?
Excellent - thank you.
Thanks for the video!
What if sleep is just the unanimus but independently evolved decision that it's easier to avoid dying when you have more information and energy AKA sunlight? And everything talked about in this video are just bonuses we've evolved to utilize during sleep to make better use of the time? What if it started as just hiding/not moving when you couldn't see because there just wasn't any information for you to process?
Of course nature is always in flux, so there are organisms that adapted to thrive in the night while everyone snoozed. And that makes sense.
Think about it, running around in the dark just gets you killed really easy. It would make sense just to pause for a while until it became practical to survive.
good comment compy
Computer other animals have adapted to seeing in the dark, like cats. But good comment i see where ur coming from
but animals that see in the dark and function usually sleep during the day
But why would it ever be efficient to be in a situation where you are completely defenseless? Doesn’t matter if it’s dark outside, it’s better to be awake in darkness than to just sleep, open to any predator. If the body could be awake 24 hours a day that would be better so it has to have something to do with the fact that the body needs to force “you” to shut down to be able to repair cells or whatever. That’s my way of seeing it anyways
@@villelofving3668 Yup,you're absolutely right. Everything in this world(Living) take some of their days to rest,Even trees,plants,animals etc.
Plants don't exactly rest but since they change their cycle of releasing the gases we could count it as rest.
I've felt naturally nocturnal my whole life. I literally have more energy through the night, and the sun being up relaxes me to sleep. So could that mean I'm deficient in a certain chemical in my brain? Could it be hereditary? I've forced myself to be on a "normal sleep schedule" for a lot of my life, but if I was given free will to sleep and rise when I choose, I would prefer to be awake at night. Any thoughts would be awesome. Cheers!
What creature r u
Because you have just found another one of your kind
Same! It just feels like the world is asleep and you're not responsible for anything and it's all relaxing ( but when u do get enough sleep, it's the best feeling everrrrrr)
Per my sleep pathologist, it’s just the result of a delayed sleep-wake cycle. You can alter it a few hours, but you’ll never have a “normal” circadian rhythm. It’s entirely normal to have as well. Some people have very early sleep-wake, some are very delayed, and everything in between. Not everyone needs 8hrs a night, either. I was actually told by my doctor that I should be getting 6-7hrs AT MOST because I just have a lower sleep need.
Oh that's interesting to know (when u know ppl are different but for some reason I didnt think it also included the amount of time u need to sleep xD)
Amazing background. i love the sky!
Real restfull sleep... Oh man that sounds so nice. I wish I could get 20 mins atlest tonight. It's been almost 2 weeks since I've had any sleep at all.
I got this video in my recommendations while I kinda need to sleep already, and also got an add about sleeping meditation or something. I think they know!

I really really appreciate your fluent English.
Me looking at videos on why sleep is important despite being in bed, exhausted and ready for sleep:
*ah yeah! This is big brain time!*
2:30 I live in Edison New Jersey, less than a block from his warehouse.
When it rains, sometimes I'll go for a walk from his warehouse, to the park and back.
Imagining that at some point, he had taken the same act walk.
Hate to sleep when I'm awake, love to sleep when pressing the snooze button. Damn you body.
By the way, you're the first to mention this 1st and 2nd sleep thing. Is there some scientific work about this behavior, because so far all I heard is between 7 and 8 hours of sleep for an adult, in one go.
That is so true
Only now I've been hearing of Biphasic sleep, and I'm 6 years ahead!
I was doing it like the ancients all along and never knew it haha
I remember listening to an historian talking about eating time through the ages in Italy, in the past they were crazy people. Eating lunch at 5 pm and waking up at 2 pm...
I love this channel so much :)
I slept 12 hours last night 10 to 10 and I took a nap righ after I came in from a 2 mile jog
2:02: am I the only one who hates sleeping with the feet outside the covers? If anything they're the only part I'd cover, otherwise, the sleep quality suffers, and sometimes I even wake up from nightmares, only to discover that I've had my feet uncovered.
Dreams have always fascinated me and how the mind is still working, thinking, ect. I have experienced entire nights of crazy nightmare after nightmare… or highly emotional ones that cause me to wake up because I’m talking.. Or sometimes I may dream of something to where it peaks my curiosity about something and I wake up to research it, and sometimes I really think we have the ability to rationalize thoughts, or discover some new information we never knew, or possibly forgotten we’ve already learned, or perhaps the type of day we are going to have, like when you think of a song and it plays suddenly on the radio…. It’s an interesting phenomenon that none of us really understand with endless ways to quantify and rationalize it, which ultimately brings me to the point of frustration in that there is essentially no right or wrong school of thought when cursed with an inquisitive mind. It’s very much like trying to accurately predict the weather, math and science allow us the ability to predict with absolute precision the movement of the stars, planets, asteroids and so on from as little to one minute, to as far as infinity, unlike weather we can’t because of all the thousands of small variables that exist on earth and the effects of events that occur beyond the planet. My goodness, please excuse me, I’m over here rambling, losing my train of thought when I should be sleeping lol
I am currently doing an online school program that allows me to do school on my own schedule, at my own pace. I have found that I am much more productive because I can sleep better, and longer. I now have a part time job, and have the best grades I’ve had in 4 years. 10/10 would recommend.
Very informative video Dr. Joe thank you! But you had me on my toes I must admit, I thought that you were going to forget to tell me to stay curious, whew.
5:17 am i the only one who can actually think of nothing? Not only on command but when someone asks me a question of which i do not know the answer to, or I need to come up with a creative idea. Just nothing. Not just repeating think of something/nothing, just nothing.
All I "think" of is black. No words, no image. Just black. It's weird
+Dr.Philry And that's something!
Yes
i once heard a sentence "you'll sleep when you're dead" and i live by that ever since...
The human mind is truly the most insanely complex thing ever!!! Love it so much
Try the universe
If you look carefully, there's a bird head hiding in the brain.
+jivenesspie I noticed that too :)
Yup
I wonder if thats where the term “bird brain” came from
The term “bird brain” comes from how small bird brains were, people thinking that you were dumber if you didn’t have a normal sized brain.
Omg yes
Young man you're so smart 👍I love ❤your videos😊❤
When i was at the uni I had the tendency to study till late st night and later i was sleepy and tired. Now i am falling asleep around 11 or 12 pm and waking up at 9am or sometimes 10am.
You say I should devote more time to it, but then you make all these awesome videos. How am I supposed to sleep without watching them all?
I don't want sleep I want answers
When it comes to sleep, I am a minimalist. I stay up late, and I wake up early. I try to get as little sleep as possible to function.
I read a paper years ago that hypothesized that sleep was the time you subconscious took to make sense of all the input you've received during the day.
I like how first and second sleep lined up with my after work naps 😂
I feel like it should be said I’m watching this at 5am and haven’t gone to bed yet
I have gone but haven't slept still :/
Title: "Why Do We Have To Sleep?"
Me: "Because we get tired."
My brain: "Click it, it might be something else."
I always sleep better when I’m camping. This video makes a lot of sense.
I tried to work night shift before and my body was tired afterwards but for some reason my body couldn't find sleep. Its why I'm glad I now work day shift.
i hate sleep. if i can do without sleep, i would.
+rocknrollch1ck - I sleep 30 min every 4 hours and I feel awesome
+Ace Striper If you're not lying/being sarcastic, (Don't you think we need a sarcasm font? This is a serious thought, btw...anyways,) then you might have solved the productivity problems of the world! Although, in fairness, having sex on that sleep schedule would be difficult...lol, sorry, i had to. :D
Jorgen Wu Search Uberman sleeping cycle. There are other alternative sleep cycles, but the Uberman cycle is the best one for me and have no problems with sex, its just sometimes your girlfriend/wife wants to cuddle and after your 30 min sleep you just stare at the siling untill you can break lose
Oh...i was joking about the sex part, but hey, thanks anyways! I'll search it, sounds promising.
+rocknrollch1ck I love sleep. Can you trade me a few hours of sleep?
This channel is absolutely amaing
No Zzzs? Lol
How cool would it be if we could be awake all the time while never feeling tired? Imagine if we can do that in the future!
I would still be useless!!
@@sureshravi9310 yea, but at least you'd be able to party non stop!
U can't live with ur friends family all the time u need just shut for some time
Fantastic video! I'm inspired to sleep on time! 😛🙂😇
