- The brain uses a quarter of the body's entire energy supply, yet only accounts for about two percent of the body's mass. So how does this unique organ receive and, perhaps more importantly, rid itself of vital nutrients? New research suggests it has to do with sleep.

I doubt I'm the only person watching this at 2 AM...instead of sleeping
nope
lmao it's 3 AM here
Watching this at 6:17 am lol
Watching this at 6am with no sleep the night before, although I am jet lagged.
3:54 to be precise
Shout out to the guy who fell asleep in the audience
lol
Lol
Lol
lol
So what you're saying is i need sleep, say no more I'm convinced. Zzzzzzz
My cat has a very clean brain.
LOL
Mine too
All the cats
I toó why not
Nice one. I love cats
Wow! Thank you. My mother suffered from insomina almost her entire life. And in her early 50's developed Alzheimers. She also suffered from a variety of mental illnesses in her lifetime. She rarely slept. This shed a new light on the subject.
Anji Udy- I have sympathy for you and your family for having to live with that terrible disorder. My worst days kept me from sleeping and it perpetuated the harshness of the issues. When my grandfather was going through heart failure, he barely slept for 6 months and kept my grandmother awake. He passed away and now she has dimentia. I always slept 8 hours a night. There was a 6 month period I only slept 4 to 5 hours a night. Then I started TM and did the night technique and I was immediately back to 8 hours the very first night.
Wow, my mother is in almost exactly the same situation as yours, only difference is she's in her 40s and doesn't have Alzheimers and I hope it doesn't get to that, she's already starting to forget and slowly losing her hearing, lots of aliments and terrible insomnia, I'm incredibly worried 😖
Rick Diaz I fall asleep fast and things have gotten better, but I always wake up and toss and turn at night because of worry of insomnia. Any advice?
@@Joe-kn4es look up biphasic sleep, it works like magic
@@Joe-kn4es,
What you need do is search ‘Roger Ekirch Sleep’.
Then you will find that awaking at the middle of the night is often a perfectly normal sign that you have gotten your first, mostly deep sleep early enough, and that you’re not sleep-deprived.

Except early to rise isn't really part of the equation.
“Early to rise and early to bed, makes a man healthy but socially dead.”

I thought it was "early to bed, early to rise, fish all day and make up lies"
@@randomredneckery3463 , you seem well acquainted with the fishermen's variation of the saying..
Thank you
This video shows a lot of insight on the most complicated human organ. As a college student who gets very little sleep, this video is eye opening to see how much sleep the brain needs. When the body is awake, the brain is demanding energy and blood supplies. We have been told that sleep helps store memory, but now science has showed how the brain cleans itself. I think to have a normal function and a clearer mind, the body needs sleep so the brain can begin another day. With little sleep, it is hard to be focused. As I received maybe only 4 hours of sleep last night, I walk around campus today like a zombie who feels drowsy.
This discovery in science has told scientists a lot about the unknown brain. I think sleep is even more important than scientists ever thought. If sleep will help prevent diseases, then that would be a break through in science. It makes sense...if sleep helps erase the waste, then no sleep leads to a back up of waste. Mental diseases could develop from this and its a theory that seems to be leading scientists down the right path. Sleep is so important to the brain and body and needs to be a priority in my opinion.
We need to find excitement in what we do. Which is sometimes hard. But that with solid sleep would be healthy for us.
I am so glad millennials are listening! This short lecture makes me want to treat my brain with so much love and respect for having directed my life so well.
When I was young, I worked and studied so many hours every day that the thought of 4-5 hrs of sleep was a luxury. Now at 75, I eat and sleep to feed my brain and live and learn daily, hoping to avoid diseases.
Does it not amaze you that Galen, two thousand years ago knew more than today's scientists? - Read Graham Hancock's book "Fingerprints of the Gods" which reveals the answers. Are we a species with amnesia? Visit his website to understand why. grahamhancock.com/books/
I completely agree with this. I've always known that sleep is needed, but to learn that the brain is essentially cleaning itself when we sleep makes me immediately realize that I've been neglecting it. I too am a college student and watching this changed my perspective and I plan to take sleep far more seriously.
Brain is explaining about itself the important of sleep
*mindblown*

zeebadz10 The brain sounds a bit full of itself
TheGuyWhoSkisWithPoi says the brain
Chronic lack of sleep, chronic foods that cause inflammation and lack of nutrients.
I bet these two play huge factors in why SO MANY people develop anxiety these years.
Cheerios !
Exactly!
I found this not only helpful but exciting. I love having a good night’s sleep. I need 7 hours exactly and i don’t even have an alarm set. I am most creative after a good night’s sleep. Isn’t it amazing how we once again find another facet of God’s divine creation!
Keep the sleep videos coming, it's importance never seems to stick with me.

Sleep a bit more and maybe you will remember.
its*
Have a rest and sleep
You can recover your condition
This is my achademy's chosen video
This is such an inspiring study , I can't believe how many times I rewatched this talk since last year , I mentioned these informations in my presentation about Alzheimer's disease in med school , thanks Dr Jeff 😉 I hope one day I will be able to do some great works in neuroscience just like this one
Great talk, the way he presented the story and conclusion was incredible.
It's always inspiring to see smart people on stage.
Kinda ironic watching this at 2am
Shivanand Pattanshetti pretty sure I could find a video on youtube about how night sleep is more important and effective than day sleep. =)
kinda ironic we live in a world that demands everyone avoid sleep and yet we can't blame Alzheimer's on these factors or sue our employer for causing these conditions.
hiphopromanesc.com
yes, I'm sure there are plenty of that concerning illumination and endocrine system activity
watching this at 4 am.
Yes!
whelp.. time to send this to ALL my college professors when i pass out in class.
Very good presentation: Clear and concise and leaving the viewer with just enough information that can be remembered. 6/2019
This is my first time watching this TED talk. This is now one of my favorite talks. It is so insightful, informative, and entertaining.
And people make fun of me for sleeping 8-10h a day... I'll be laughing when you can't remember your own name!
Hahahahaha
Same here
@OmegaAlphaTau do you know what is the percentage of those who oversleep and that of those who undersleep?
@OmegaAlphaTau Yes but 8 - 10 hours is fine. 7-8 is the ideal minimum for peak performance sleep (only in adults, the younger you are the more you need). 10 hours isn't the danger zone.
Same
Outstanding lecture!
Thanks to scientists like Jeff, we we are being lifted out of ignorance of our universe and to ourselves into an enlightened state of being. That is a greater degree of consciousness.
Thanks Jeff.
Well on one hand you have people like Jeff . . . _and then there are the religious ones~_
This is also making me think about the positive impact of powernaps or quick sleep (15-20min). Imagine you "clearing" your brain one or two times a day by a quick nap and then a solid night sleep. That should get the brain even healthier and more responsive.
I'm really inspired right now but at the same time my brain is giving me obvious signs on the need of a real "clearing".
Goodnight.
Nice to see someone who didn't overload us with examples and analogies and stuck to just one
Super fascinating, concise and also easy to make sense of for a non scientist. Thank you!
Most underrated TED talk in regard to actual consequences for everyones life. Good sleep is the most important factor for health, affect/mood, cognitive functions etc.
Jeff, you're an excellent educator!
beautiful talk, there is so much more to learn about our own bodies.
This is one of the best videos ive watched. period. well done
So clearly explained and exciting to see what's going on when we sleep 👌🏻
Great TED Talk. I learned a lot. Thank you!
When binging on UA-cam videos when I should be sleeping, I watch videos about the importance of sleep. It gets me to go to sleep very quickly. 👍👍
Excellent speaker! Amazing topic!
I have been very unstable lately due to not getting sleep. Thanks Ted for making me understand maybe why that is.
The discovery that Jeff explains in this video is one of true hope. People in the healthcare system don't always take the time to figure out why something happens or how something happens they just accept that it does and move on. If we could take the time to learn what is going on and learn why these things are occurring we could possibly prevent common diseases like this in the future. All too often, doctors jump to medication thinking that it is the only answer for the diagnosis, but what if they took the time to understand the mechanisms behind it? Would that change the way they plan to treat the patient? I think our healthcare system needs to operate like this more often. There are many diseases that are well known and the issues causing them are as well. But, what if we studied other diseases to try and get a better understanding and possibly find a treatment that works even better than the medication that was previously used. I find that pills and capsuled medications are becoming more and more popular and are used almost every time someone goes to the doctor when their could be a better alternatives somewhere that is yet to be discovered or is not that well known. I hope that research like this continues and is expanded to other diseases to inform people about what is happening and how to prevent it.
Some people know what is the root problems of (I think almost) all diseases like Alzheimer disease, diabetes, cancer, osteoporosis, aging, coma, etc. as well as how cells really are and function, such as Ray Peat, Otto Heinrich Warburg, and Gilbert Ling.
Ray Peat's site: raypeat.com/
Gilbert Ling's site: www.gilbertling.org/
I think health care in the future will focus more on understanding the cause rather than fixing the symptoms with a pill. The body knows how to heal. We need to work with this. Drugs are working against the body.
Medicine school only teacher to student how drugs to prescribes.
Deep sleep means dreams ? or dreams could happend outside of the deep sleep ?
Sugar. Sugar causes and or exacerbates almost every single health problem in the western world. Don't believe me? Try and cut sugar from your diet. If you even succeed for a week.... You'll understand.
Amazing speech! Thank you!
this talk is amazing thank you
I thoroughly enjoyed this insight. 100%
Great presentation! I started cringing towards the end as I realized how little I sleep compared to how much I should sleep.
Bravo👏👏👏it's very important and interesting information😊😍thank u so much
Fascinating talk - thank you!
Dr Jeff lliff excellent TED presentation, amazingly interesting
I have liked the way he has explained processes in the brain!
Wow, absolutely fascinating talk!
grazie mille per la traduzione, per settimane ho faticato nella traduzione e ora ho colmato le lacune, grazie mille
absolutely INCREDIBLE video!!! Explains why people have "breakthrough thinking" in their early morning hours (Hour of Power)...avoid brain clog....go to bed earlier it all catches up to us.... all this in 11 minutes... THIS GUY WAS GOOOOOD
Excellent, thank you.
I wish he addressed when was the best time to go to sleep and wake for optimal brain health. Great presentation. I get good sleep, but this reinforces good habits over bad. After reading some comments, the idea of insomnia sounds terrifying. Not being able to sleep. Scary.
Now if only I actually could get a good night's sleep.
***** As it is also interconnected with spine problems, anxiety, depression and a whole lot of other things.
***** And not having nightmares every night, right?
Have more Magnesium(Mg) intake. It helps with sleep. Bolthouse Farms has a drink called "Vanilla Chai tea". Its really good in helping with sleep.
Now if I could only get myself to bed at a decent time..
Excellent video I remembered a lecture years ago about This and how they developed in the brain, some how that research was stopped. In my mind it makes sense today. It only occurred in the brains of alcohol users over time.
Fascinating. Thanks for posting:)
Amazing, thank you I will share on!!! :)
What a beautiful laid out explanation
Side effect of research publication.
Wow.. This video was pretty useful and very informative and interesting.
Very very useful in a very basic way! Well done...
I'm curious if and how this discovery will impact our understanding of migraines. Perhaps there is a type of waste not being cleared, or CSF is pushing on the brain while awake, like a leaky pipe. Also, which cleaning system evolved first, lymph or glymph? VERY nice work. I appreciate the love, thought and thousands of hours which go into this exciting research!
Great presentation ❤
Useful and interesting...
You are speech is amazing.
Thank you!
Please recommend these earlier in the day, UA-cam. Otherwise I end up watching these at midnight.
Important for kids ,students, young people or less young....to get a good sleep !! All of us need a good sleep, also for so many other reasons !!.... Great job.
This explains why so many sleep deprived people suffer from stress and depression. A lack of sleep can lead to anxiety and even diabetes. Rather worrying in this age of 24/7 “entertainment”.
One of my favorite videos !!!! :D
As a Muslim girl, I was struck by how this lecturer is fascinated by the mechanism of the brain’s work and the accuracy in its manufacture and creation.. I would like to tell him that this beauty, science and accuracy in making, came from the Great Allah who created us and created.
everything with great precision and wisdom, the Almighty.
سبحان الله العظيم خالق كل شيء ✨.
One of the best TED vedios
Excellent video on some aspects of sleep science. The findings regarding beta-amyloids are quite interesting. The findings regarding cerebrospinal fluid are also interesting and surprising. But what makes cerebrospinal fluid flow and how does this vary between the wake mode and the sleep mode of the brain?
When you have an assignment to submit the next day, and writing a summary about this video happens to be the assignment. Mind you, it's 3 am and I'm going stay up late finishing this off. FML.
Hi, it's me, your future you!
Nice !!! love it ! it meant alot to me
so good dr
I am currently sleeping less than 3 to 4 hours a night, I get into a position of spine decompression, I also have a pad and pillow that has a kind of acupressure and am currently devoting time to a hyperbaric chamber/Float therapy box that also does self hypnosis that would include topical nutrients in mass amounts of anti oxide to help my fluid last longer without recharge, and treatment for our skin based on known bloodlevels of healthy skin's with nutritional content.
I'm watching this when I should be reading for college. Well, the topics kinda line up, so it works.
Can you do the same research with meditative brain. Because when we sleep our brain is at rest, and while meditating brain and mind is at rest. It would be great if that resesrch can be done on meditation .
When a person is asleep, he enters into a deep state of meditation. When the sleepingbrain is in the delta and theta waves frequency similar to deep meditation, the same cleaning process is likely to happen too.
Meditation is OK but nothing beats a cat nap. Your mind is so refreshed afterwards.
While listening the one of the old Greek physician's ideas presented in this talk, i was thinking that may be we should introduce something like Bonferroni correction for Multiple Hypothesis Matching... given enough crazy thinkers, there will always be one whose ideas will fall in line with current scientific paradigm ;)
Good video I learned a lot. 😄
I should have known about that video many years ago!!!
Would it be possible to trigger the process while you are awake? I wonder what that experience would feel like.
I've read the UC Berkeley news last year about their findings that poor sleep can lead to dementia. Listening to Jiff, it all makes sense to me. Here's an except of UC Berkeley article:
“Our findings reveal a new pathway through which Alzheimer’s disease may cause memory decline later in life,” said UC Berkeley neuroscience professor Matthew Walker, senior author of the study published today in the journal Nature Neuroscience.
Additionally, I've watched Dave Asprey's recent videos in his UA-cam's Bulletproof channel talking about sleep quality, which he also talked about the glymphatic system.
Amazing!
OF COURSE I would see this after not sleeping well last night. Thanks Ted-Ed.
Anyone knows, where to find the papers to this study?
Would like to look at the details. For example in which cycles it happens. Does it happens the whole night. Are there intervals, etc
superb informative presentation! thank you.
This new discovery is really fascinating. It might lead to new treatments for brain diseases. Ted talk is one of the best of all out there.
Was there a specific stage when you saw the CSF rushing in? Stage 4 maybe had the most flow?
5am and I'm still awake. Great!
That is an ingenious way of our brain to do such a task. Although, how long does it usually take? Does it take the 8 hours which is usually recommended for sleep or is it only a single hour?
Now, this is what I'm talking about. This is an exceptional TED talk, not like that new-agy crap they've been posting lately.
Few slides, correct deep professional non-stop talking...man you know your job! kudos
Excuse me, everyone. Can you instruct me how I can do if I wanna have full English script of the video? Thank you so much!
Thank you for making Japanese sub
Interesting speech.
Regarding the 8m47s mark, Dan Pardi on the neurohacker podcast, suggests the body produces these beta-amyloid proteins outside the cells as a response to protect itself, and it provides scaffolding within the cells... and that the effort should be to promote those natural processes that clear it, rather than externally trying to remove them, since that may cause more harm than good.
Also are all stages of sleep, observed to have the same level of glymphatic/cleanup activity? For example, if REM time is maximum as a fetus, and decreases linearly as we age, are there differences in the CSF flow between REM and NREM (5m20s)? REM sleep also seems to heighten with heat, for example, when you're sick with the flu... does it make sense to try to promote REM sleep (ex. via Galantamine)?
Standing O for this man!
Very interesting!
Absolutely fascinating video! Thank you for sharing such great information. Makes me think, wow! God is such an amazing Creator!!
This talk has literally put me to sleep ;)
eyeCU13 lmao
Not clever or funny
Doesn't make sense, if it has LITERALLY put you to sleep are you writing in your sleep ?
I wonder how long after you go to sleep does this occur and if someone does not sleep well at night but are able to nap in the afternoon for about 30 minutes would it work then or does it need the full eight hours at one time?
Hmm.. its 3AM and I'm watching this
News Flash: Get sleep
Bright blue light keeps you awake. Get 'f.lux' for your computer.
+Octamed Thank you!
I’m losr
nice talk...
A very interesting video explaining the real reason for sleep. Now I can understand why we feel all foggy and lazy if we don't get enough sleep.
How’s is your sleeping after 7yrs? lol
Im currently deciding if I should sleep now or stay up 2 more hours to get 4 hours of sleep.
One problem, I just slept for 3 hours a while ago, though.
One problem I see with his explanation is that he says the CSF only floods during periods where the brain is at its most inactive, but the human brain is even more active in REM sleep than it is during consciousness. How does he account for this apparent discrepancy?
Correct, and a lack of REM sleep is almost as damaging to the brain as no sleep at all.
I wonder if it has anything to do with this "cleaning system". He talks about how brain cells shrink to make room for CSF (which corresponds to early stages of sleep, right?) maybe REM sleep is a way to squeeze that fluid back out. Obviously I have no idea what I'm talking about, just a thought.
I think REM happens when the brain is in Alpha or Theta, but when the brain is most relaxed, called delta, It's dreamless sleep. People who practice transcendental meditation get into the delta brainwave mode, which is why there's so much clarity that comes with meditation.
HigherPlanes Do they use crystals too?
kakashi76767
Not sure what you mean by use crystals, but I do own a few.
This was actually brilliant. Watching this at 9:23 pm! Woohoo!!!
Clever design. Thank you Jesus!
Bemused but not confused. Been there ... done that...attaching religion to this...??? don't brag but take credit where it is due. What you state is your opinion only..... repeat ...only
Really?
