If you are looking for someone who is regular in his sleep, certainly not the one to count on Evening is when I do my best work and the best time to play. Waking up at 8 AM is not my style And, while a part of me wishes, I never slept, I definitely enjoy it. One of our strongest vital requirements is the need for sleep One of the few desires that we cannot control. In fact, sleep deprivation can lead to death faster than food deprivation Time, to find the scientific reason that we do a third of our lives Try to stay awake for it, Although the average person will spend 25 years of his life sleeping, There is no scientific consensus On exactly why we do this. One thing we’re sure to know is that our brain definitely thinks sleep is important. Deep in the hypothalamus is the small walnut-sized region at the bottom of the brain. You have a group of cells that is your biological clock. The nucleus is called the suprachiasm When exposed to light. This small group is busy releasing hormones like cortisol And inhibits the secretion of inactive hormones such as melatonin, And does the opposite when it gets dark. The second sleep trigger is thought to be an adonisin build-up in the brain. Adonisin is a by-product of your nerve cells, And the other cells when damaged, are ATP. The basic molecule that our bodies use to store energy Research indicates that when a group of adonisin residues builds up in your brain, You feel sleepy. We previously talked about adonisin when we discussed the science of caffeine Because the effect of caffeine occurs through its binding to the same receptors as adonisin. It tricks the body into thinking, it’s not tired, But when you sleep, your adrenaline levels drop, And gradually your nerve cells absorb it again. This is what makes you feel somewhat relaxed when you wake up, So we fall asleep when our brain tells us that, But this does not answer the most important question: Why are we programmed to sleep Seems like a very annoying thing to do? It is also dangerous if you are surrounded by leopards or others. There are many theories and it is unlikely that any of them is the only answer. Instead, they can all contribute to this strange craving That necessitates us to lose our awareness. First of all, mammals and birds, sleep And other creatures, such as reptiles, insects and fish, show sleep-like behavior. This includes even a millimeter-long nematode that is put under pressure when it refuses to rest. Some scientists suggest that staying at night is an evolutionary adaptation that enhances animal survival By keeping him safe from danger when he is most vulnerable to it. Sleeping can be a way to stay still so that you don’t attract attention, Even so. The lion sleeps 15 hours a day While it can be said that the giraffe is the delicious meal of the sad lion. You sleep less than two hours a day, So another theory is that sleep might be a way to conserve energy Life in general and at least in the wild, is all about providing the calories to keep going So getting rest. The third of your day is fine. Humans use approximately 10 % less energy during their sleep, Our breathing heart rate, and body temperature. All drop Sleep theory is often reinforced by the fact that it secures a return to a normal state. Sleep is when muscle tissue grows, your cells produce protein and your tissues renew themselves. It secretes growth hormones, But of course, we can take care of that without losing consciousness right. That is why our body does not repair itself when we sit on the sofa And we watch “ Milwaukee Housewives”
Because our minds need sleep as much as our bodies do. New research suggests that sleep allows the brain to regenerate And, even more importantly, can reorganize. This theory is known as brain plasticity. We all do and see different things every day We can remember most of them when we wake up, but not necessarily all of them. The plasticity of the brain explains that sleep is when it replaces and stores the events of the day. It saves approximately 8 hours to process and capture new memories. This theory supported human trials in one of the experiments. A group of volunteers memorized a set of patterns in the morning. The other group did so in the evening. The brains of the morning group were tested. After 12 hours without sleep, The evening group was tested 12 hours later, but after they fell asleep The evening collection proved to be a plus for remembering patterns. It can be good advice to take a nap when you run into problems Or slow down before making an important decision. Your brain needs time to absorb everything, you’ve noticed, But if sleep enhances the strengthening of the brain, What about the things we want to forget? For example, there is no reason to remember the color of the car that crossed my path in the morning Or the words of a radio ad where someone sings about furniture. Fortunately, sleep can help filter all of the junk and excess from our brains. When you make memories during the day, The brain strengthens the nerve connections or the connections between nerve cells. Learning new things usually causes neurons to form completely new synapses By tracking the flow of electronic activity that occurs thousands of times every night. Among the billions of your nerve cells, Scientists discovered that during sleep, Both high and low frequencies flow, but the moderate frequencies decrease their flow. In other words, your brain chooses to either increase or calm the nerve connections it produced. While you sleep, As a result, each bond is strengthened or weakened, Although it’s a little sad when you think about it, The insignificant details of the previous day are likely to be lost forever. After you, wake up Keep in mind without the daily filtering. Your brain can face a lack of energy And space crunch and somehow the sleep function is like doing a hard disk format. The problem is that people and Americans in particular, are not getting enough sleep. The National Sleep Foundation did the research On average. Americans earn less than an hour Of the recommended. Eight hours per night Teens need more too. Likewise, nearly 20 % of Americans report trouble sleeping More than 200,000 car accidents every year caused drivers to become sleepy Killing more people than driving under the influence. It doesn’t take long for the brain and body to feel the effects of sleep deprivation And problems arise over time.
Just spend one night without sleep and your brain will quickly start trying to fight Beginning with the amygdala. A part of the brain that tells the body to prepare for when danger is imminent. Short-Term sleep deprivation causes the amygdala to overreact. Thus it obscures the prefrontal cortex. This is the part of the brain that controls logical thinking, among other things, So waking up all night. It can sign you in a situation that a researcher calls Jell-O Because when it exceeds the prefrontal cortex, The sleep-deprived brain connects to another part And which, from an evolutionary perspective, is one of the oldest and most primitive regions. The blue locus of your brain is called ( locus coeruleus ), Because for some reason the fabric is blue. Its job is to motivate you to instinctively respond to stress and panic, But it can interpret almost anything as a threat. Car derailment short mail, impromptu comment from a companion. It leaves you anxious and suspicious of everyone and everything. The longer you sleep, the worse things, get Memory and control of speech are the next two exposes of suffering, but only after several days, Things look very strange. General paranoia can reveal more and more pronounced hallucinations. Some have interpreted this to mean that your brain forces you into an awake state, But the question is: can lack sleep really kill you? The answer is almost certain. Yes, Sleep is directly related to healthy immunity. Studies reported a 50 % decrease in antibodies in those who underwent the trial, And they were only deprived of sleep for a week Which exposed them to receive diseases And in a well-known study on sleep from the 1980s conducted by sleep researcher, Alan Rachfan, A group of Sleep-Deprived mice all died within two weeks. The reason as far as Rakshafan turned out was simply exhaustion. They had no physical defect. A later experiment conducted in 2002, similarly failed to find an apparent cause of death. So you probably want to know how long you can go without sleep, The longest recorded state of a person, volunteering to be awake is 264 hours, Or about 11 days. It happened in 1965 when 17-year-old Randy Gardner set a record As part of his science project. Gardner appeared relatively healthy, most likely a result of his age. In the end, however, he was described as cognitive impairment. When he was awake, he felt blurred vision and involuntary eye movements. His hallucinations included seeing fog around streetlights and feeling a fanciful hat ribbon, And he thought he was the San Diego Chargers’ back-back. I think the lesson here is not to try to break the Gardner record At the next science. Fair in your school. No good will come from that. Thank you for watching this episode of Sai Shaw.
