Your brain will literally start dreaming while you're awake if it doesn't get enough REM sleep. Matthew Walker explains the horrifying reality behind delirium tremens (the DTs): When chronic alcoholics quit drinking, the massive backlog of suppressed dream sleep explodes into consciousness. The brain becomes so desperate for REM... that it hijacks wakefulness — you start hallucinating dreams in real time. It's a full collision of two states of consciousness. You can even see it on brainwave scans. Walker’s point is chilling: if the brain is willing to break reality itself to get its missing dream sleep, that shows just how non-negotiable sleep is. Mother Nature spent 3.6 million years hardwiring in that 8-hour requirement for a reason. This is why sleep deprivation is so destructive. Have you ever learned a sleep fact that completely changed how you see rest?show more

I had no idea that horses are physically unable to dream unless they feel safe enough to lie down. They sleep standing up most of the time. Their legs have a built-in locking system that holds them upright without any muscle effort. But standing sleep is only light sleep. To reach REM sleep, the deepest stage of rest where the brain processes memories, repairs the body, and produces dreams, every muscle has to completely relax. That can only happen lying down. Lying down makes a horse completely defenceless. It takes several seconds to get back on its feet, and in the wild that delay can be fatal. So a horse will only lie down to sleep when it completely trusts whatever is around it. In wild herds, at least one horse always stays standing while the others rest. If a horse feels stressed, alone, or unsure, it simply won’t lie down. It will go days without deep sleep rather than take the risk. So this horse, flat on its side, completely out while its owner sleeps against it, isn’t just napping. It has decided this person is safe enough to be completely helpless around.

Dr. Andrew Huberman (Andrew D. Huberman, Ph.D.) explains how exercise and sleep interact to sustain peak brain function: - Acute sleep loss (one night): “Sure go ahead and exercise”—keep it moderate to offset cognitive drag while minimizing injury/immune risk. - Prolonged inactivity (>10 days): “You start to see significant decrements in brain oxygenation levels.” - Morning exercise + bright light (+ optional caffeine) is a “terrific way to improve the amount and quality of sleep that you get at night.” - More deep & REM sleep translates to stronger memory, steadier emotions, and long-term neural health.

🚨SLEEP DEPRIVATION DAMAGES YOUR BRAIN—LITERALLY Sleep deprivation isn’t just tiring—it’s brain damage. A study on young participants found that just one night of bad sleep increased levels of the protein S-100B by 20%—the same spike seen in traumatic brain injuries. Once in the bloodstream, this protein triggers toxicity, potentially leading to neuronal death. How do you prevent this? Get high-quality sleep. Treat bedtime like the most important appointment of the day. Source: Instagram/ bryanjohnson_

“WOW!” Joe Rogan’s brain nearly exploded when Dr. Matthew Walker explained what just a one-hour difference in sleep can do. When we spring forward for daylight savings time, “we see a subsequent 24% INCREASE in heart attacks.” But this is the part that blew Rogan’s mind: “In the fall, in the autumn, when we gain an hour of sleep, there’s a 21% decrease in heart attacks. So it’s bidirectional.” “Wow!” Rogan said, stunned. “That’s how fragile and vulnerable your body is to even just the smallest perturbation of sleep,” Dr. Walker explained. And if losing or gaining just one hour can swing heart attack risk that dramatically, imagine what years of bad sleep are doing to your body. 🧵

If you're sleep deprived, one of the best things you can do (counterintuitively) is high-intensity exercise. A few hours of sleep deprivation reduces insulin sensitivity and impairs cognitive function. But just 10 minutes of HIIT can enhance brain blood flow, cognitive performance, and blood glucose regulation. It can take you back to baseline, or even above it, for several hours or until you can get adequate sleep. You may not feel like going hard when you're tired, but the short-term benefits are real. Just don't make poor sleep a habit.

Sleep isn't downtime, it's your brain's number one recovery protocol When your sleep is poor, the first brain function to go is vigilant attention That means you lose focus, and ultimately get less done So despite what many think, trading sleep for work actually makes you less productive It matters more than you think

Kevin O'Leary reveals he drinks wine at breakfast to get better REM sleep "Unfortunately, sleep doesn't work with alcohol. I don't smoke, I don't do drugs, but I love wine. If you drink wine 3 hours before bed, you don't get any REM sleep" "So the strategy is drink at breakfast and don't drink again. Because if you can get those 7 hours of sleep, the diet and exercise, you can't believe how you feel"

Bryan Johnson explains how lack of sleep can increase the risk of cancer ''When you get 4 hours of sleep per night or less for a few days, your NK cells, which are the cells that survey your body for cancer, go down in activity by roughly 70%. So a way to increase the risk of cancer is low sleep'' ''You can increase the risk of cancer when your body is in poor health. When you are older and when your immune system is not as strong, you have a higher chance of getting cancer''

‼️BIG TECH IS NOW RELEASING A DEVICE THAT WILL MAKE YOU CONSCIOUS INSIDE YOUR OWN DREAMS Prophetic, an American technology company, has officially launched a device capable of tapping into your dreams. Not just to observe them, but to remember, shape, and control them. Here is how it works. The device sends low-level ultrasonic pulses through the forehead and directly into the prefrontal cortex, the part of the brain that goes quiet during regular dreaming but lights up during lucid dreams. By gently reactivating that region, the device pulls your sleeping brain into a state of full awareness, where you know you are dreaming and can steer where it goes. The last frontier of human privacy was your mind while you slept. That just ended. The WEF's "you will own nothing and you will be happy" just got its biggest upgrade yet. Why spend years convincing you while you are awake when they can simply program it in while you sleep? Nothing to see here. Absolutely nothing can go wrong. Sweet dreams. They are counting on it.

REM (Rapid Eye Movement) sleep is a unique stage of sleep where your brain becomes highly active, your muscles are temporarily paralyzed, and most of your vivid dreams occur. It’s a crucial part of the sleep cycle, playing a big role in memory, learning, and emotional processing. credit: mrbrainboost on IG

Not many people will tell you about the problem of sleeping on the left side so I will tell you... The problem with sleeping on the LEFT side is that the liver is located in the upper quadrant, when you sleep on the left for 6-7 hours, due to gravity, the liver can actually COMPRESS the heart - which you don't want happening Solution? Before you go to bed, obviously don't sleep on your stomach but rather SLEEP ON THE RIGHT! Watch this short and simple video below to explain why you shouldn't sleep on the left or sleep on your stomach but rather why you should ALWAYS sleep on your right - watch it 10 times if you need to:

Losing just one hour of sleep could take you four days to recover ➡️The optimum sleep duration is 7-8 hours per night. ➡️Lack of sleep (sleep deprivation) results in various problems, such as poor attention, focus, concentration and memory. ➡️Poor sleep also increases the risk of headache, anxiety and stress. ➡️Sleep deprivation is associated with poor decision making and driving errors, leading to more vehicle crashes. ➡️The most important aspect what I wish to highlight is that: Losing just one hour of sleep could take up to four days time to recover. ➡️Therefore, ensure a regular sleep schedule and sleep for 7-8 hours every night. #sleep #sleepbetter #sleephealth

Bryan Johnson’s Best Health Hack Will Help You Sleep Better and Live Longer “The single best thing I've learned out of everything I've ever done is (lowering) your resting heart rate before sleep is the best thing you can do for your health. Hands down.” “Let's say it's 60 beats per minute. Your goal over the next month is to lower your heart rate by 10% or so. So if you're 60, be down at 54.” “Here's how you're going to do it.” 1) No food for 4 hours before bed 2) No screens for 1 hour before bed 3) Amber and red lights in your house, no blues 4) No caffeine after 12pm “The reason why your heart rate is so important is the lower your heart rate is, the better your sleep, the better your sleep, the better your willpower.” “Did you know, if you don't sleep your prefrontal cortex goes offline and you lose your willpower?” “So when you're trying to not eat the cookie, you're powerless. You can't do it. It's gone.” “I promise you, this is the single best thing you can do for your health.” Bryan Johnson
