- 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
"early to bed, early to rise, makes a man healthy, wealthy and wise." -B. Franklin
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
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.

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.

yes, I'm sure there are plenty of that concerning illumination and endocrine system activity
watching this at 4 am.
Yes!
Keep the sleep videos coming, it's importance never seems to stick with me.

Sleep a bit more and maybe you will remember.

Have a rest and sleep
You can recover your condition
This is my achademy's chosen video
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.
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!
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
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.
Another reason I quit weed.
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..
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!
This is my first time watching this TED talk. This is now one of my favorite talks. It is so insightful, informative, and entertaining.
I doubt I'm The only person watching this at 1:45 AM ....... Instead of sleeping
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.
whelp.. time to send this to ALL my college professors when i pass out in class.
If the brain uses such a large amount of the body's energy, why can't you lose weight by thinking really hard? :)
Actually you do
Self placebo-ing is possible.
You don't see obese scientists very often, do you?
Fatima Ramirez
Yes, that is why stress can lead to weigh loss i'm assuming?
Lol don't be lazy, exercise
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~_
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
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.
It seems a bit odd how this guy's talking about one of the more interesting enigmas of the human body uncovered in recent history, and when the camera pans over to the audience they look like they couldn't be paid to give a damn.
I think a part that plays into it is our current lifestyle. For the most part (or from what I am able to perceive) sleep is shunned. Saved only for the weak and lazy. People just don't have the time to sleep more.
Leading me to believe that the people in the audience were to tired to give a damn lol
Show us your twitch video of you watching this video. I bet you looked really bored until the bit where you realised you could comment about the audience.
Steve Carter yea u want them to cheer or something
@Anonymous Anonymous How could a person possibly present an important topic on the brain and not use oroper names for things. Maybe you need to take a nap before you try and watch this video.
@Tartarus "Medical jargon"? Dude, this is simple high school biology.
I have been very unstable lately due to not getting sleep. Thanks Ted for making me understand maybe why that is.
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 ;)
Please recommend these earlier in the day, RUclips. Otherwise I end up watching these at midnight.
The moment you're watching this at 2a.m.🙄🙄🙄🙄😴😴😴😴😴
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”.
Great presentation! I started cringing towards the end as I realized how little I sleep compared to how much I should sleep.
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!
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 ?
Very good presentation: Clear and concise and leaving the viewer with just enough information that can be remembered. 6/2019
My name is Jeff
قال تعالى:- ( وَجَعَلْنَا الليل لِبَاساً . وَجَعَلْنَا النهار مَعَاشاً )
I'm about to take a 2-3 hour nap after watching this.
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.
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 ✨.
notes!
why is sleep so restorative?
sleep is an elegant design for the brain’s waste removal
-the circulatory system provides nutrients to every body cell
-every cell creates waste; the lymphatic system removes this but there are no lymphatic cells in the brain
-how does the brain clear its waste?
-brain has cerebral spinal fluid (CSF) which removes waste
-CSF moves along brain blood vessels
this only happens when sleeping
-when the brain sleeps, brain cells shrink, which makes room for CSF to rush through brain and remove waste!
-when awake, brain is busy, puts off waste removal process until sleep
what kinds of waste?
amyloid beta (AB) - Alzheimer’s is the accumulation of AB, but this doesn’t prove a lack of sleep is the cause
sleep literally “refreshes” the mind!
more notes! www.kevinhabits.com/ted/
Help me I have'nt sleep good from 10 days😢 and I tried everything my brain is like my friend and it's tells me why I want to sleep what the fuck...I'serious replay if you have any answer how can I knock out my brain for sleep it's not good I hate my brain really...😢😢😢
The buildup of these wastes may contribute to the psychosis that meth users experience after being awake for several or many days...
Watching this damn well knowing I‘ll only get 4 hours of sleep.
I want to sleep nowwwwwwwwww.
Woah, talk about a wake call!
Watching this at 3:30 AM so that I can motivate myself to sleep
its 5 am , i should go to sleep why am i wahtchig thiisajddalsjfkdsfhkdjbvdjfkgijdnigdsnfisdkffjhhhhhhhhhhhfhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhjjjjjjjjjjjjjjjjjjjjjjjjjjjj
Watching this at 3AM. Cue Third Eye Blind and another half dozen cups of coffee.
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?
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?
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.
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!
everyone can guess sleep is good but do you have a magic cure for insomniacs if not why add to there anxiety
*the ironic thing is that im watching this video at 20 past 12 at night*
If u will not sleep properly ur body will refuse to work because it is not fully recovered
Let's assume he's right, and that the purpose of sleep is 100% about cleaning and refreshing the fluids. Wouldn't it be theoretically possible to effectively reduce the time per day needed for sleep simply by making that process more efficient with external manipulation like nanorobots or some kind of a drug?
Mustafa Ali our heart and other vital systems need rest too.
I don't think it works that way. It was designed with and for a purpose, and I don't think we can circumvent that.
Clearly an INTELLIGENT Creator designed this ELEGANT system after He forgot to give the brain lymphatic vessels.
HE? or s(he)?
I don't need reasons to sleep. I want to sleep but I can't 👁 👁
I'm watching this at 5:35 am COME AT ME SLEEP DEPRIVING FACTORS!
Science will bring you to God
stop with the "intelligent design", people. god made a waste problem only to solve it and couldn't just make it work without complications with his usual magic?
but hey, god is so complex, he must have an intelligent creator: uber-god
uber-god is so complex, he must have an intelligent creator: super-uber-god
Ever thought that GOD is not s(he) ?
Watching this at 2;30am #oops
I treasure sleep like a hungry man craves a burger. I love sleep.
So clearly explained and exciting to see what's going on when we sleep 👌🏻
Update: There _are_ lymphatic vessels in the brain (not that it changes the thesis of the talk)....
Human and nonhuman primate meninges harbor lymphatic vessels that can be visualized noninvasively by MRI:

Dirty countertop vs. "dirty mind": it is surprising that some people choose to clean the first.
Lady told me that having much money might not make you happy,...but allows you to sleep good, cause youre not worried about rent and bills.... i think shes right.🤔

This video is only ever recommended to me after 2am
I try not to sleep, I feel like I'm wasting time when I go into semi a coma..
Me too!!!!
Me too but I have eye dark circle.
When you reach your 30s you'll probably think differently. ;)
@@portalkey5283 Some people never reach their real 30s. They can be 50, but stay as immature as 12 year olds.

I used to think I was sleep deprived but I actually have a genetic tear duct deformity. It is so annoying because it makes me look older and tired.
grazie mille per la traduzione, per settimane ho faticato nella traduzione e ora ho colmato le lacune, grazie mille
Super fascinating, concise and also easy to make sense of for a non scientist. Thank you!
50 - 70 million US adults have a sleep disorder. Which means, you are not alone in your quest for better sleep. Think of it this way, if you're awake at 3 PM, so are 45% of your neighbors and city. I use a sleep mask and it works wonders. Since i've started using it on a daily basis, I sleep through the whole night and wake up rested.
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.
Well Tyler Durden only slept 30 mins per night ;) ;)
Jeff, you're an excellent educator!
This information was covered on dnews about a year ago! He totally claimed it as his own!
Newspapers don't do primary scientific research, they present other people's research. Most likely, the research they presented was his.
Useful and interesting...
I wonder what the results of this "cleaning process" are between people who have a lot of dreams and those who don't. It might seem that dreaming brains are not resting the brain as much……..?
+Summer Hemmingway I think that dreams could be the result of free diffusion of some neurotransmitters when brain is flushed at night. have you had this experience that after a nasty busy day with some unfamiliar new tasks you have a whole lot of rushing meaningless bizarre dreams?
Summer Hemmingway apparently we all dream though many of us don't remember dreaming
One of the other talks said there is a deeper level that refreshes the brain. The fact that you are dreaming might be a good sign that your brain got rest and is ready to go.
Absolutely fascinating video! Thank you for sharing such great information. Makes me think, wow! God is such an amazing Creator!!

Now that we have answered many of the mysteries of sleep, the mystery becomes: *why* did the central nervous system evolve a different lymphatic system from the rest of the body?
I have the same question. How can the brain 'think' to itself: no that's not what I need, I need something different?
Would it be possible to trigger the process while you are awake? I wonder what that experience would feel like.
Is it possible to re-hydrate the brain without sleeping?
You didn't watch this until the end , did you...
lapinschous1 I did watch until the end, but I hate sleeping. I'd rather stay up and use another way to re-hydrate the brain.
Look into Da Vinci sleep, you train your brain to sleep only 2 hours a day and still rejuvenate your mind fully
Hey ever hear of water YA that hydrates nah just kiddin I have to say just go to bed
Jessey Bowman If you had actually watched this until the end, you'd know that Lliff saying that sleep clears the brain of wastes, not "re-hydrates" it because it had been dried up all day.
If you want good sleep please do walk 6 km everyday then see what will happen becoz i experienced
I have liked the way he has explained processes in the brain!
can we make a case for naps for adults
Ima stop watching this and go to bed
The funny part, is that I am staying up late and watching this haha...
Nice
Great talk, the way he presented the story and conclusion was incredible.
It's always inspiring to see smart people on stage.
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 I have more explanation for my mom on why to sleep at least 10 hours XD
Hello, this is a program called "The Emperor of Thumbs" by MBN, a South Korean broadcasting station. Can we use the cerebrospinal fluid experiment data from 5:08 to 5:55 during Jeff Ilif's lecture?
Now I really appreciate the sleeping and my brain😘😘
Yea, TED has a good presentation (just almost slept through three bad ones). In full disclosure, I have a very rare neurological disease (adrenomyeloneuropathy) and honestly had to learn to give myself permission to sleep and not feel guilty about it. Oh my, I just noticed this presentation was more than five years ago. I hate it when I'm late for TED presentations. Seriously, can someone explain me how to remain as current as possible. Thanks.

Was there a specific stage when you saw the CSF rushing in? Stage 4 maybe had the most flow?
