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. ------------------------------------------------------ #Sleep #SleepDeprivation #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

What If You Stopped Sleeping for a Week?

What If You Stopped Sleeping for a Week?

People spend almost half of their lives sleeping, and still seem to never get enough of it. Have you ever thought what would happen if you stopped "wasting time" on this process? You would surely have a lot of free time for learning something new, doing sports, working, or just hanging out with friends. Sounds cool? But let's have a look at the consequences of never sleeping again. After one day without sleep, you’ll feel better than ever. The reason for these strange feelings lies in the fact that your brain increases dopamine levels trying to compensate your lack of sleep. However, closer to the end of the day, this happy mood is evaporating. It's strictly "not recommended" to drive in such a state, as it may turn extremely dangerous when you're sleep deprived. After two days without sleep your body will have less and less energy, and you will begin to look pale and a bit ill. What is even worse, your immune system will start to let you down becoming less efficient. Your judgment will get impaired. What is more, the effects of the absence of sleep will be getting worse and worse, and after a short time, the body will begin to shut down. This means that after three sleepless days you'll be unable to function or communicate normally. If you manage to fall asleep on the 11th day, shockingly, there won't be any long-term health effects. This means that after a good and quality sleep lasting about 12 hours, you will be perfectly fine. This doesn't refer to those people who suffer from fatal familial insomnia. Such patients can survive maximum for a year, and a half granted their condition was worsening gradually, and they still managed to sleep from time to time for the first several months of the disease. Music: https://www.youtube.com/audiolibrary/music TIMESTAMPS After one day without sleep. 0:44 After two days without sleep.1:51 After three days without sleep. 2:52 How long is it possible to survive without sleep? 4:02 Recommendations how to fall asleep more easily 5:34 SUMMARY -This may seem weird, but after 24 hours without sleep, you'll start to feel happy and elated. -As soon as the second day without sleep starts, you will have some important physical functions getting shut by your body. For example, its ability to metabolize glucose will be lost. -You will start to hallucinate after three days with no sleep, and your body will be desperately trying to rationalize the feelings it's experiencing. -The maximum recorded time without sleep was approximately 264 hours, that's about 11 days. After that, the body shuts down completely which leads to death. -Figure out your favorite sleeping position. Before going to bed, enjoy a nice warm shower or a bath with eucalyptus or lavender bath salt. Sleep in the nude. Start to control the light you're exposed to a couple of hours before you go to bed and add some gentle sounds. Don't eat before going to bed.
