人睡多了 会脑衰

人睡多了 会脑衰 Do you sleep too much, and your brain will decay? Baidu knows that the Internet user has been able to answer: Do you have this feeling when you take a nap? You want to take a break, and the more you sleep, the more sleepy you are, the more sleepy you are, the more you sleep. Don't want to get up at all, and just go to sleep the whole afternoon? And then he got up and he didn't know what to do... Is it bad for you to sleep too much? Why do people even think that sleeping more can lead to premature brain failure? Why do you sleep? Sleep about a third of the time in our lives, we all know that sleep is good, even if the lack of comprehensive understanding, we in the case of lack of sleep for a long time will naturally feel body state is worse. Now, the mystery of sleep is unraveling through research into humans and animals. Survive the first explanation came from point of departure, such as "inactive Theory (Inactivity and found)" think, in the vulnerable period or easy prey, animals will take "inactive" strategy. For example, in the evening, you may be injured because you can't see the road, and you simply don't go anywhere, and rest in place, so you get a lot of sleep in the long term natural evolution. But even if you stay still, there is no need to sleep... There is a Theory of "Energy saving (Energy Conservation) and found" that at the time of inactivity can sleep to save Energy, at least when hibernating animals do consume less Energy, also can get a similar benefit when we sleep, but it should not be all. In recent years, "Restorative Theories" have been supported by large Numbers of experiments. It suggests that people can repair the body and rejuvenate the damaged body during sleep. The most typical example is that if the animal lasts for several weeks without sleep, it will lose immunity and even cause death. And large amounts of physical activity, such as muscle growth, tissue repair, protein synthesis and the release of growth hormone, occur mainly or only during sleep. On the other hand, people awake brain releases adenosine (adenosine), it is considered related to fatigue - a cup of coffee may be able to offset its effects - when we sleep, the body will remove these adenosine, therefore, when we wake up will feel again. In addition, the Brain Plasticity Theory (Brain Plasticity and found) "are supported, the structure of this Theory is that sleep and Brain neurons and the way of organization change, also is the development of the Brain or refactoring, is directly related to the cognitive and learning. The related mechanism has not yet been fully understand, but a lot of evidence to suggest that it is likely to be correct, such as baby take 13 to 14 hours a day to sleep, sleep in the infant brain development played a decisive role. More sleep? As a result, adequate sleep is very important to all of us, otherwise our immune system will decline, and the efficiency of study and work will decline. Studies have found that a person who stay up all night on the reaction time is needed for the normal state of things around three times the concentration caused by error of chance will increase greatly. If they don't sleep for 48 hours, 72 hours, or even 96 hours, they tend to perform worse and worse, even mentally and emotionally. The weakened immune system will make us more susceptible to colds, fatty liver and other diseases, and the risk of cancer will increase dramatically, leading to premature death. But is it better to sleep as long as possible? That's not the case, as Jane e. Ferrie of the university of London, who wrote in 2011, analysed 4,972 men aged 45 to 69, 1,459 women, 4,531. Results found that people sleep time should be between six to eight hours, or 7 hours, up and down, and sleep 7 hours every day in all the tests performed best, The second is that six hours of sleep, if less than six hours, or more than eight hours, cognitive decline. They think sleep time is too long or too short, and the poor sleep quality will lead to brain aging 4 to 7 years in advance, cognitive decline faster, thereby affect the brain function, resulting in physical deterioration and early death. This research with the other research results, such as the United States, according to the results of a research programme to sleep more than nine hours every night of the probability of suffering from Parkinson's disease than 6 hours under high 80%, 60% percentage points higher than people under 8 hours sleep. And liquidity is poorer interior sleep for a long time in air, as people consumption, breathing will gradually reduce the oxygen in the air, may cause the lack of, the result is more sleep more trapped, the more trapped want to sleep, but after up feeling groggy and headache. In addition, the long time rest often lead to cardiac activity ability is abate, eventually make the person's activity is abate, if sleep does not rule, is likely to lead to different heartbeat, physical fatigue and other symptoms. [scientific sleep] For the sake of our health, sufficient and effective sleep is very important, for scientific and reasonable rest, we need to pay attention to method, ability to be more than half the effort. First of all, the schedule should be regular. Irregular work and rest is one of the problems of modern life, very little sleep, a lot of people Monday to Friday and even some only 5 hours, and then sleep over the weekend, but it's not science. This is especially true for children, another study showed that of the university of London is not a regular routine will affect the child brain development, which will affect their life. Healthy sleep from 11 at night before sleep, at least until 4 o 'clock in the morning should be the sleeping state, because the body is rhythmic, your immune system will work at this time, remove the invaders, the body will be repaired at the same time, missed the time also missed the chance. As a result, people who stay up late tend to be more likely to catch colds or other illnesses, and if they do have a task, sleep early and work early. In addition, you can take a nap at noon, which is between 11 a.m. and 1 p.m., and it won't take you long, maybe 20 minutes or a little longer. In addition, a good sleeping position is also important, adverse sleeping position can affect health, such as the desk lunch break, even the arm pillow, better not to sleep. The lateral position can have a variety of, such as, generally left side help digestion, but puts pressure on the heart, so people with cardiovascular disease such as side, right side should be adopted; And lie on your back, relax the facial muscles, can delay the appearance of wrinkles, also do not oppress organs, is suitable for patients with high blood pressure, at the same time, it is also a male best sleeping position, because there is no adverse effects on the reproductive organs, but don't put his hands on his chest, can affect the breathing or nightmares. Prone sleeping position should be held shoulder to shoulder, but because the oppression organ, also affect the breath, not desirable, but to the patient of lumbar vertebra is a choice. Finally, don't be too aggressive when you get up, just in case the brain suddenly doesn't have enough blood, and it's better to stay in bed for a few minutes before getting up.
