What is the reason for having a nap and dreaming?

Dreaming is a physiological phenomenon, but some people think that dreaming is a bad thing. Dreaming prevents them from getting enough rest, which will damage their brains after a long time. In fact, this kind of worry and panic is unnecessary.

Dreaming is good for people. Professor Koth huber, a German neurologist, believes that dreaming can exercise the function of the brain. He said that only some brain cells are active at ordinary times, that is, during intense mental work, only some brain cells are active, while others are dormant. These dormant brain cells will gradually decline if they are not used for a long time. In order to prevent this decline, dormant brain cells can only exercise themselves and exercise their functions by dreaming during sleep, so as to achieve the goal of self-improvement and non-decline. Some people think that dreaming may be a working procedure of the human brain. By sorting out the information received by the brain during the day, the information that the brain can't process during the day can be well processed in the dream, and the problems that can't be solved by hard thinking during the day can be solved in the dream at night. For example, Voltaire, a famous Russian writer, often finishes the conception of a poem in his sleep. German chemist Kekule discovered the cyclic structure of benzene in his dream.

According to the EEG test, it is also found that the activity of human brain is quite intense when dreaming. We can detect fast and disordered brain waves from dreaming, and its intensity sometimes exceeds that when awake. From this perspective, dreaming is a self-need to exercise the function of the human brain. There is an old saying in China: "Blind people have no dreams, fools have few dreams." Although this statement is somewhat arbitrary, it also shows from one side that people with little knowledge and stupidity rarely dream. On the contrary, dreamers are mostly people with rich thinking and imagination. Of course, if you don't sleep, you will have nightmares, which should be another matter.

Dreaming, like doing other things, should have a limit. Excessive dreaming will be counterproductive and endanger people's physical and mental health. Frightened and horrible dreams often wake people up from sleep, and it is difficult to fall asleep after waking up; Strong and deep dreams will leave deep traces in brain cells, making the brain tired and unable to rest. It is generally believed that the best way to dream is to recall a dream last night the next day, not a specific dream.

Patients with neurasthenia often have difficulty falling asleep, and when they finally fall asleep, they are often awakened by nightmares, which interferes with normal sleep, makes them groggy and listless during the day, and even produces hypochondriacs and anxiety from dreams, which aggravates the development of the disease.

According to Zhou Xiaoning, director of the Department of Psychiatry of Hubei Provincial Hospital of Traditional Chinese Medicine, people sleep from shallow to shallow, and they are in a state of deep sleep when they sleep, so people don't dream. 1-2 hours later, people begin to enter the shallow sleep period, the first dream begins, and then appears in cycles. People usually have 4-6 dreams a night.

Some people in MUBI, some people have few dreams. This is mainly because some people like to recall their dreams, so they will feel MUBI.

Zhou Xiaoning said that dream memories are mainly related to people's personality and way of thinking. Generally speaking, introverted and neurotic people dream more. Especially when they are worried and stressed, they dream frequently because of sleep disorder, and then wake up and treat it as a symptom without asking why, and panic in vain. At the same time, they tried their best to find sleep measures to get rid of the pain of insomnia, and the situation became more and more serious.

For such people, Zhou Xiaoning suggested seeing a psychologist, trying to shift their attention from themselves to the outside world, supplemented by some drugs to promote sleep.

Regarding dreaming, Huang Huaijun, director of the psychiatric department of Zhongnan Hospital of Wuhan University, also believes that dreaming is a normal physiological phenomenon of the human body. When people sleep, the clarity of consciousness will decrease. When thoughts, memories and imagination in daily life stimulate some parts of people's cerebral cortex and leave traces, but when people stay excited during sleep, the traces left in daily life will become active and cause dreams.

However, Huang Huaijun reminded that if you often have nightmares or sleepwalking, you must seek medical treatment, because such people are a disease with sleep disorders. Long-term sleep disorder can easily lead to heart disease, hypertension, arteriosclerosis and cerebral thrombosis.

People must wake up in time when they have nightmares, because it is easy to cause pain in the process of nightmares. After getting up, people will also bring depression, anxiety, insomnia, depression and unresponsiveness. If this happens repeatedly, it will pose a threat to people's health.
