Everyone should have a good sleep after a busy day. Sleeping is a kind of physiology.
sleep
Reaction is a part of brain nerve activity, and it is the result of inhibition of neurons in cerebral cortex after continuous excitement. When inhibition is dominant in the cerebral cortex, people will sleep. People have a combination of work and rest all their lives; In neural activity, there are excitement and inhibition. Inhibition is to protect nerve cells, make them excited again and let people continue to work. The daily sleep time must reach 1 1 hour for children,1hour for primary school students, 8 hours for junior high school students and 7 hours for senior high school students.
Sleep is also a process of memory cell metabolism: aging cells input every arrangement of memory information into new cells for storage. Including sports, language areas, balance keys, some past events and memories in daily life. They are all matter, so they also exist in the form of matter.
If a person's long-term lack of sleep causes memory cells to live healthily, it is prone to some health problems, even diseases, such as aphasia, convulsions, convulsions, or shock and fainting caused by forced sleep. It is easy to become cancerous after a long time.
From the point of view of natural science, it is best to wake up naturally, otherwise everyone will die. A regular life is a good foundation, but it is dangerous to work hard for a long time for the sake of "regularity" Scientists suggest that people with financial ability had better let nature take its course, and don't damage their health just to flaunt morality.
Because after all, for farmers, "going to bed early and getting up early is good for health" is linked to the relations of production. If farmers don't get up early to work, herd cattle and farm, they will have no food. How to be healthy without eating for a long time? Therefore, if you are not a farmer or just trying to make a living, there is absolutely no need to torture and abuse yourself.
Yawning is the first signal to remind us of lack of sleep. If/kloc-stays awake for 0/8 hours, the human reaction time will change from 0.25 seconds to 0.5 seconds and continue to increase, while ordinary people will have paroxysmal sleepiness; About every 2 to 20 seconds, you will find that you need to reread what you have just read; Eyelids are getting heavier and heavier; After 20 hours, you will start taking a nap. Studies have shown that the reaction speed of normal people at this time is basically the same as that of people with a blood alcohol content of 0.08-if you keep this value, it is easy to violate the rules. You will forget many things, such as writing the wrong name or forgetting to hold the hand brake.
In the animal kingdom, sleep is as important as food, water and sex. Everyone from fruit flies to modern people is like this. But scientists can't know exactly what sleep does. Is it to refresh yourself? Not exactly. As we all know, muscles don't need sleep, they just need intermittent relaxation. Is it to keep a clear head? Almost. Good sleep is good for the brain, but there is no consensus on how the brain benefits from sleep.
One theory is that sleep helps the brain to store all the information that humans receive when they are awake. Another view is that sleep is to restore energy. It has also been suggested that sleep often uses some mysterious forms to help us master various skills. So, what is sleep?
Two things happened in the mid-1990s, which brought the focus of research back to the real purpose of sleep. 1994, scientists from Weizmann Academy of Sciences in Israel suggested that scholars' research should focus on the problem of false memory processing, and the technology of peeping into the sleeping brain was greatly improved at that time.
Scientists at Weizmann Academy of Sciences have found that people's rapid eye movement sleep is directly related to their ability to recognize fixed patterns on computer screens. This technique is called program memory, which requires repeated operation and practice. Memorizing facts, such as the name of the president of the United States, is declarative memory-an ability that has nothing to do with REM sleep. Robert Stickgold, a neuroscientist at Harvard Medical School, said: "Our understanding of memory is always naive."
Sleep quietly
But for a while, scientists suddenly made clear the direction of memory research. In the past few years, Stickgold and his colleague Matthew Walker have studied the effects of sleep on procedural memory of motor skills at Beth Center in Boston, USA. They asked right-handed trainees to type a string of numbers as quickly as possible with their left hands over and over again. They found that no matter what time of the day the experiment is conducted, the accuracy of the trainees will increase by 60%-70% after 6 minutes, but if the trainees take the experiment in the morning and re-test it after 12 hours, their accuracy will not be greatly improved. However, when students train at night and take the test after getting up, the speed will increase by 65,438+05%-20%, and the accuracy will increase by 30%-40%. To the surprise of experts, those trainees who made the greatest progress spent the most time on non-rapid eye movement sleep. Other training about vision or perception requires the trainees to have deep sleep or both slow-wave sleep and rapid eye movement sleep. Sometimes, even closing your eyes for an hour can make a big difference. At other times, a good sleep is very necessary.
I hope it can help you solve the problem.
