One more reason to get a good night’s sleep | Jeff Iliff

[@anjiudy3297]

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.

[@rickdiaz100]

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.

[@Ghosty716]

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 😖

[@Joe-kn4es]

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.

[@kenmarriott5772]

We need to find excitement in what we do. Which is sometimes hard. But that with solid sleep would be healthy for us.

[@chm825]

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.

[@jasmin4428]

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.

[@user-hk8gp7ui6s]

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 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.

[@haleyann6996]

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.

[@MrGodofcar]

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/

[@kenmarriott5772]

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.

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 KZbin's Bulletproof channel talking about sleep quality, which he also talked about the glymphatic system.

[@lxc647]

beautiful talk, there is so much more to learn about our own bodies.

[@Earthatrip]

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!

3:00 - "This diagram shows the body's lymphatic system which is evolved to meet this need..." 4:00 - "Well that seemingly mundane question is where our group first jumped into this story. And what we found, as we dove down into the brain--down among the neurons and the blood vessels, is that the brain's solution to the problem of waste clearance was really unexpected. It was ingenious. But it was beautiful." So first we have a complex system (the body) that clearly didn't have a complex sub-system (the lymphatic system) at one point, and thus the need to "evolve" it. My question--how many bodies would survive without a lymphatic system? And of those that survived, how long would it take them to "evolve" such a complex sub-system? And secondly, adjectives such as ingenious and beautiful can only be attributed to intelligence. Humans create beautiful things. Animals do not. They create functional things. Humans create ingenious things. Animals do not. They create whatever they are programmed to create, with some room for adjusting to environmental factors. "Genius" requires a being with intelligence. "Beauty" requires a being with inward and outward awareness, perhaps even morality. It is not possible, let alone probable, that complex systems such as the human body, composed of complex sub-systems, came into existence through mutation and death. Complex systems are designed. They are created. And complex systems such as the human brain, the complexities of which we are still seeking to understand, do indeed require a Designer and Creator with immense "genius." And if the same person created all the beautiful animals, all the marvelous insects, not to mention the stars and galaxies, then he must also be the source of all moral good in the universe because only such a being could create such "beauty." But why is the world so broken? Why is everything dying? Why do we see such beauty and such corruption? What happened to this place? What happened to us that we, of all the creatures on the planet, create weapons of mass destruction that could, in a second, snuff out the lives of millions of people? Why do we lie, cheat, steal, lust, and murder? Why does no one have to teach the infant child how to disobey? If you are a rational thinking person, you must face these facts and these questions. If you value truth, you must exercise an open and inquisitive mind.

[@kavidaswani8139]

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 .

[@limtk55]

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.

[@MikeTrieu]

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?

[@kakashi76767]

Correct, and a lack of REM sleep is almost as damaging to the brain as no sleep at all.

[@23cokebottles]

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.

[@HigherPlanes]

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.

[@kakashi76767]

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?

[@Kevin-xs8xn]

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/
