What Happens To Your Body And Brain If You Don't Get Sleep | The Human Body

Sleep expert Matthew Walker breaks down the many effects of sleep deprivation on your brain and body.
Following is the transcript of the video:
Matthew Walker: My name is Matthew Walker, I am a professor of neuroscience and psychology at the University of California, Berkeley, and I am the author of the book "Why We Sleep."
We certainly know that a lack of sleep will actually prevent your brain from being able to initially make new memories, so it's almost as though without sleep the memory inbox of the brain shuts down and you can't commit new experiences to memory. So those new incoming informational emails are just bounced, and you end up feeling as though you're amnesiac. You can't essentially make and create those new memories.
We also know that a lack of sleep will lead to an increased development of a toxic protein in the brain that is called beta amyloid and that is associated with Alzheimer's disease because it is during deep sleep at night when a sewage system within the brain actually kicks in to high gear and it starts to wash away this toxic protein, beta amyloid. So if you're not getting enough sleep each and every night, more of that Alzheimer's-related protein will build up. The more protein that builds up, the greater your risk of going on to develop dementia in later life.
What are the effects of sleep deprivation on the body? Well, there are many different effects. Firstly, we know that sleep deprivation affects the reproductive system. We know that men who are sleeping just five to six hours a night have a level of testosterone which is that of someone ten years their senior. So a lack of sleep will age you by almost a decade in terms of that aspect of virility and wellness.
We also know that a lack of sleep impacts your immune system. So after just one night of four to five hours of sleep, there is a 70% reduction in critical anticancer-fighting immune cells called natural killer cells. And that's the reason that we know that short sleep duration predicts your risk for developing numerous forms of cancer. And that list currently includes cancer of the bowel, cancer of the prostate, as well as cancer of the breast. In fact, the link between a lack of sleep and cancer is now so strong that recently the World Health Organization decided to classify any form of nighttime shift work as a probable carcinogen. So in other words, jobs that may induce cancer because of a disruption of your sleep rate rhythms.
We also know that a lack of sleep impacts your cardiovascular system because it is during deep sleep at night that you receive this most wonderful form of effectively blood pressure medication. Your heart rate drops, your blood pressure goes down. If you're not getting sufficient sleep, you're not getting that reboot of the cardiovascular system, so your blood pressure rises. You have, if you're getting six hours of sleep or less, a 200% increased risk of having a fatal heart attack or stroke in your lifetime.
There is a global experiment that is performed on 1.6 billion people twice a year and it's called daylight saving time. And we know that in the spring, when we lose one hour of sleep, we see a subsequent 24% increase in heart attacks the following day.
Another question, perhaps, is what is the recycle rate of a human being? How long can we actually last without sleep before we start to see declines in your brain function or even impairments within your body? And the answer seems to be about 16 hours of wakefulness. Once you get past 16 hours of being awake, that's when we start to see mental deterioration and physiological deterioration in the body. We know that after you've been awake for 19 or 20 hours, your mental capacity is so impaired that you would be as deficient as someone who was legally drunk behind the wheel of a car. So if you were to ask me what is the recycle rate of a human being, it does seem to be about 16 hours and we need about eight hours of sleep to repair the damage of wakefulness. Wakefulness essentially is low-level brain damage.

[@frutigermetroboomin]

The part where you can't form new memories is so real. I've experienced that to extreme degrees. In school, I remember being perfectly able to grasp every piece of material we were taught, but without being able to remember it for extended periods of time. I would only be able to remember a few things, then the rest would go down the drain. It was exhausting. I needed to work way harder than necessary, but I was of course too exhausted to put in all the work needed to keep retaining all the information I kept forgetting. This was also a huge problem when I started my first part-time job. Mind you, it was in a pharmacy, so there was a lot of information to take in. I would constantly be told how to do certain things and forget in the next second. It was terrible having to ask for help again and again. Then I told my boss about how I slept very little and she encouraged me to go to the doctor. I was actually sleeping so little that I was at the point where I would wake up feeling "normal" after 3-4 hours of sleep (not good). I was seriously mimicking ADHD symptoms, hell, even dementia. I was tired, demotivated, discouraged, clumsy, impulsive, unaware and absent-minded. But it was my normal and I didn't think about it. I was a child/teenager and my knowledge of the effects of sleep deprivation was highly limited, up until the age of 17-18 when I started reading about it.

[@lemonpoundcake22]

How are you doing now? Going through this rn. i stay up late looking at too much youtube or social media 😔

[@omg-bz4cp]

​@@lemonpoundcake22You just have to force yourself to put the phone down. If you have trouble sleeping, just close your eyes and you will eventually sleep even if you think you're not tired. When you close your eyes, you're telling your body that you're ready to sleep. Also, I recommend doing something tiring hours before bedtime so you can easily fall asleep, maybe do 100 jumping jacks, just do something to make you tired

I have suffered lack of sleep from chronic pain issues over the years and finally developed fibromyalgia which stopped me sleeping almost completely until I was prescribed medication. I find such difficulty falling asleep now even when really tired and it’s definitely had an effect on my mental capacity and physical health over 20 years and dreadful brain fog is an example of this. Ability to remember things is now so bad, it does make sense why and also my mom hated sleep and spent hours reading in bed. She had a heart attack and developed dementia. Sadly I can see me doing the same but I love sleep when I can get it. It makes such a difference to your day when you’ve slept well! On my gravestone I’d like “Peace at last- Do not disturb !” 🤣🤣

There are better things to do, things that make you happy and thus help to stay healthy, too. Especially if you feel like you already understood the stuff in class. Rather discover who you truly are, what you like, what you want to do in your life, if that's realistic and if so, find out how you can reach that goal. And then chase it with your eyes wide open. Coming from someone who has failed to do so because of several reasons.

I have extremely severe central sleep apnea that went undiagnosed for over two years. I complained about being extremely tired all the time to my doctor several times but they blamed it on my medicine. When I say extreme, that’s really an understatement. I dosed off constantly, even on hard plastic chairs. Nothing I did helped. Finally my doctor agreed to do a sleep study. I was told I shouldn’t be alive, that’s how bad it was. I stopped breathing 150x per hour. That’s 5x more than what they consider severe. To make matters worse my file was misplaced when it was supposed to be expedited and it was another six months before they finally got back to me. I sure hope that it doesn’t effect me later in life. Watching this video scared me a bit. I’m getting better sleep today and my central sleep apnea is under control. Brain signals are struggling in other areas yet but not so much with sleep. I have a lot of family history of heart problems too. Both my parents died from heart failure and had heart problems, my maternal grandpa died of a heart attack and my fraternal grandma had heart problems. I feel like I’m doomed after watching this and knowing what I’ve learned from doctors. I’m not even 40 yet.😢

Happy to hear that you are getting better sleep now than before. I suffered from depression for decades. I was suicidal. I was going through chronic sleep deprivation during the time.

With clean lungs, I breathe in so much that I feel like being outdoors a lot. In my opinion, good clean lungs are critical in getting good sleep, and driving away depression.

[@shinyy187]

I remember being in navy basic training and somewhere around the 36 hour mark of no sleep I would start going into a “deep sleep” and have a dream that would all last a second or less, then snap myself awake, only to “fall asleep” again for a split second. This was at any point in the day no matter what I was doing and I couldn’t control it.

[@Cobra427Veight]

When I first started night shift , and wasnts sleeping to good , and on a bad night with lots of problems , I could fall asleep standing up but after a split second your knees collapse and wake you back up .

[@shinyy187]

@@Cobra427Veight Yeah. I don’t know if this is the same for others but I found the nights to be easier to stay awake when very low on sleep. As soon as morning hit, it was hell.

I started working nights recently at my job and have only been able to sleep 5-6 hours at a time. I’ve been feeling noticeably worse than I used specifically more depressed and irritable than I used to be. I have also seen a large decline in my ability to think straight and not feeling as mentally sharp as I used to. Once I get more adjusted to my new hours I should be able to sleep better hopefully.

[@TheAnarchist99]

I remember when I lasted 48 hours without sleep because of depression and chronic anxiety , I was about to take my own life back then and couldn't manage to sleep well for such a extended period of time. I literally felt numb , dizzy , depressed , angry , suicidal and had murderous thoughts as well, I began hallucinating after 36 or so hours without sleep , pretty terrifying all these experiences, all of that combined with social isolation and social anxiety literally made me low-functioning and even getting up from a chair felt hard. No one was there to help me at the time, I didn't know how bad was that and it definitely took a toll on both my mental and physical health, fortunately now I'm much better and almost back to normal and I don't pull all nighters anymore.
