pt 1 Sleep solution by Chris Winter MD book review

Ajouté : 2026-05-11

[00:00:00]Okay, this video is part one of a book report. Here's the book, The Sleep Solution by Chris Winter, MD. He's like a neurologist who specializes in sleep disorders.

[00:00:09]Um, he first, you know, begins by mentioning that beta amaloid protein is a major neuronal waste product and the glimpmphatic system, which is a, you know, port manto combination word of gal system, the supporting cells of the brain and lymphatics. the lymphatic system working together. Clear out the toxic chemicals from the brain at night while we're asleep. Um, and it works better the lymphatic system if we're sleeping on our side. It's natural to sleep on your side. I always start the night out by sleeping right side down because your stomach empties to the right. Just, you know, Google anatomy of the stomach. You see, it always drains to the right. I've seen hundreds and hundreds of berium studies. Soon as the patient lays right side down, stomach starts emptying out more rapidly. Um, it also keeps it away from the left side of the stomach where the esophagus is connected and can cause reflux. Okay.

[00:00:57]Um, interesting thing is he talked about students pulling an all-nighter and he mentioned that the adenosine will keep accumulating so they're going to be sleepy the next day during the test. But it's worse than that. They can't clear the neuron neuron beta amaloid protein.

[00:01:11]So they're going to have more beta amaloid toxin around the nerve cells and it's an exytotoxin. And it also causes inflammation in the brain because it activates microgia who then release their toxic chemicals. Um so you're going to have brain fog. You're going to be sleepy and it's worse than that. Uh the beta amaloid protein itself uh besides all that irritating stuff. Um in addition you also I'm sorry another thing is that you're going to have difficulty consolidating your memories because while you're asleep REM consolidates your memories. It takes new information integrates it with what you already know. That's why you often wake up in the morning. You've got the solution to a big problem.

[00:01:47]Okay? So, write it down right away before you forget it. Sleep deprivation makes you fat because it elevates cortisol that is associated with obesity, but it also lowers increases the hormone grein, the hunger hormone. I remember G for ghrein, G for gastric, stomach. So, it makes you hungry. So, you overeat, get fat. It decreases leptin. Leptin is the stop eating hormone. Um, leave the table hormone. So again, you overeat and you get fat. You crave junk food also like you know processed food and stuff when you're sleepd deprived. Poor sleep is associated with obesity, hypertension, diabetes, coronary artery disease, congestive heart failure, aphib, stroke, impulsive behavior, major depression, depression disorder, anxiety, car accidents, etc. Just when they impose uh daylight savings time, when you lose that hour, have to get up earlier than you wanted to, there's more car accidents and heart attacks that day.

[00:02:38]Significant increase. Shift workers have terrible health. Man, you don't want to be doing shift work after you're 30 years of age, especially. They got a marketkedly increased amount of cancer.

[00:02:48]U because I can remember nurses telling me, "Oh, their friend who works the night shift got breast cancer. Their friend who works a night shift got melanoma." Here's the cover of the book, The Sleep Solution by Chris Winter, MD, neurologist, sleep specialist. Okay. Uh sleep drive is built up through the day.

[00:03:02]The longer you're awake, the more um adenosine your body produces that accumulates in your brain until you're asleep. It's only when you're asleep that it gets cleared away. So the point I'm saying is that if you don't get your sleep, you're just going to get sleepier. That's why all nighters are a bad idea. Exercise increases the denosine, which is what you want. So that exercise helps you sleep better. Like I said it before, I consider a treadmill the magic sleep machine. The longer you walk, the better you sleep. The faster you go, the better you sleep. I routinely on a day off, I'll walk routinely five to seven miles. Uh what's next? Caffeine blocks adenosine, blocks the adenosine receptor. So caffeine prevents sleep. Normal sleep, you start out awake, you move into light sleep, then you move into deep sleep. Deep sleep is also called nonrem sleep. The body can move uh but you know it's kind of limp typically. It's it's it's a time that's been described by Matthew Walker as the information of the hippocampus initial memory storage short-term hippocampus being like a thumb drive is then sent temporary storage is then sent to the cerebral cortex like a hard drive for long-term storage and it's largely a one-wave transmission. And he likens it to AM radio going one way out to the cortex. And then he says sleep. You go back to light sleep phase. Then you go into RM sleep. And during RM sleep the body's paralyzed so you can dream safely without moving and acting out your dreams and potentially bumping into your your significant other in the bed next to you or sleepwalking and you know getting hurt or something. Um so paralyzing the body enables you to dream safely. And during that dreaming that's the phase where you know the the EEG waves they look like you're awake. Okay.

[00:04:36]they're even more so. They're even more active when you're awake because all that information is being bounced around with the information stored in your cerebral cortex to see where it fits to integrate it. And that's why when the next day you can use that memory more effectively. Uh typically adults spend about 25% of their time in deep sleep and it's mostly early in the night and the deep sleep is more restorative.

[00:04:56]After you've got the deep sleep, you feel stronger. It improves bone mineralization and that's partly because more growth hormone is primarily secreted during that time and it builds muscle mass, maintains muscle mass. This is why for an athlete you want to especially athletes should be told to go to bed early so they get more of that um deep sleep. You get deep sleep in the first third of the night especially. So the first half of the night and you if you go to bed late you lose out on deep sleep. If you wake up early you lose out on sleep. Okay. So sleep is the second half of the night primarily especially towards the end of it. Each average sleep cycle is about 90 minutes and again the early sleep cycles of the night are primarily deep sleep. The late sleep cycles of the night are primarily REM sleep. Okay, REM is real important for memory for creativity and all that.

[00:05:46]So if you're an intellectual, you want to uh be getting your RAM sleep definitely and that's again why you sometimes wake up in the middle of dreaming in of a dream and you'll have an idea or you'll be you'll be able to remember the dream if you woke up during it. Uh so anyways, I thought that was interesting especially that the growth hormone is secreted during deep sleep and that maintains muscle mass and strength and that's also why you can feel relatively okay even if you only slept 5 hours because you got your deep sleep but your brain's not going to be as sharp as you want it to be and in the long run you're going to start burning out if you don't get more RM sleep as well. So anyways uh that's it for part one. I hope you found this helpful.
