Why do people sleep?

People have been thinking about this problem since ancient times. We only know that people's brains feel tired after work, so they need to have a rest. Sleep is the best way for the brain to rest. But sleep and brain are both friends and enemies, and how they coexist harmoniously is still inconclusive in science. Sleep plays a very important role in people's lives. Poor sleep can cause nervous system diseases, and long-term lack of sleep can even lead to nervous system disorder, which makes people crazy and die. A long time ago, Britain had a very cruel criminal law. They made the prisoners stand at attention, opened their eyes wide and prevented them from sleeping. No matter how strong people are, they can't survive 10 days. Even if you don't die, you will look trance and be in a state of madness. Lack of sleep especially affects people's mood. If you don't sleep well at night, you will be listless, in a trance and fidgeting during the day, which will inevitably affect people's work and study. In the long run, it will form a vicious circle. If you don't want to become hysterical, you'd better seek the help of a psychologist in time. Generally speaking, people's normal sleep time is 8 hours a day, but some people only sleep 4~5 hours a day. Peter the Great slept very little, so it is no wonder that when he was building the new capital, Petersburg, he personally patrolled until late at night every day. People get less sleep when they are old, not that they need less sleep when they are old, but that they have less time to sleep when they are old. The continuous reduction of sleep is one of the important signs of human aging. The idea that the longer you sleep, the healthier you are is also wrong. Because sleep should not only stress the length of time, but also pay attention to the quality of sleep. There are many reasons for insomnia. Faced with disharmony in family life and unsatisfactory work and study, people's nerves will be in a state of high tension or excessive fatigue, and it is often difficult to fall asleep at night. In addition, some people are too excited to sleep by watching exciting TV or novels before going to bed. Some people read until late at night, thinking that they can get enough sleep later the next day, and as a result, they have missed the best sleep time. Even if you sleep for 8 hours, you won't get the corresponding effect. Therefore, developing good habits of work and rest is not only beneficial to your health, but also brings you a good mood. People are lonely at night. At night, when people look up at the starry sky alone, they often feel inexplicable sadness. On the one hand, you may be in a bad mood during the day; On the other hand, the influence of moonlight on people's physiology and psychology should not be underestimated. As we all know, strong ultraviolet radiation from the sun is the chief culprit of the increase in the incidence of skin cancer. I didn't know that the soft and quiet moonlight would lure people into a melancholy and sad kingdom. On a full moon night, Indians wear white ornaments on their heads when they go out to reflect the moonlight and reduce its harm to people. When they sleep at night, they draw curtains to keep out the moonlight. Because the full moon has the strongest radiation, it will disturb people's nerves and make them crazy. Medical research has proved that the depression caused by moonlight is difficult to treat, and when it is serious, it will lead to moonlight mania, which is often called sleepwalking. There is a boy named Jim in America who often runs out of the house at night and runs towards the river at the head of the village. Father and mother tried to chase him, but little Jim ran very fast, waded on the foggy river and soon disappeared in the moonlight. The next morning, people found little Jim sleeping among reeds. When Jim woke up, he didn't know what happened last night and was confused. Mystery, which once swept the world, explained: "As an entity in space, when people are irradiated by moonlight (not excluding starlight), the vibration characteristics of body cells will change, so sleepwalkers can lose weight like ghosts, run lightly and gain magical abilities." Russian science fiction writer Alexander Beliaev described many hypnotic states of people under the mysterious call of moonlight in his works Ai Kang Wuqi and Heavenly King Wei. Vladimir Bekhterev, a famous expert in nervous system pathology in the Soviet Union, put forward a unique hypnosis theory by studying the influence of moonlight on human nervous system, which was widely used in medicine. Freud once said in The Interpretation of Dreams that the study of dreams is a shortcut to psychoanalysis. In primitive times, people thought that people's souls could communicate with ghosts and gods in their dreams, so what they saw in their dreams was the letters of ghosts and gods. According to the Old Testament, the Egyptian king dreamed that seven lean ears of wheat swallowed seven fat ears of wheat. Yue Se explained to him that this was a sign of seven famine years after seven bumper years. The King of Qi listened to his words and saved Xiaomi for seven years. Then there was a seven-year famine, and people saved themselves from famine by accumulating food. Every one of us dreams every day. Dreaming is good for the body, and it can relieve the pressure of people's troubles during the day. But if you often have nightmares or wake up from dreams, it is very harmful to your health. People often have hallucinations in dreams, and sensory stimulation in sleep is also easy to cause dreams. People's imagination is most active in sleep. An incomplete illusion may be the center of a complex scene. Many psychologists have systematically investigated the influence of human perception (including vision, hearing, touch, taste and smell) on emotions, and found that vision has the greatest influence on people's emotions. Therefore, carefully setting the color matching of the living room has gradually become a science with great market potential. You may feel disappointed when you stand on the balcony at night. Don't stay too long, because the melancholy king is working his magic at this time. Moonlight stimulates your optic nerve, which will make you feel inexplicable sadness. Moonlight can not only affect people's nervous system, but also affect other abiotic objects. Someone has done such an experiment. They put the grinded saber on a bluestone board under the full moon and found that the sharp blade of the saber had become dull after a night of irradiation. Natalia Cliza Lida, an associate professor of philosophy in the Soviet Union, suggested that everyone spend one year making statistics on their emotions and analyzing the relationship between emotional changes and the moon phase cycle. If you find a pattern, you might as well make corresponding adjustments before your depressed days come, and you will certainly benefit a lot from it. Having said that, you may have understood that your irritability and depression have a lot to do with your sleep. If you have insomnia, don't take sleeping pills easily. You can drink a cup of warm milk with a spoonful of honey half an hour before going to bed. If you suffer from insomnia for a long time, you may wish to adopt the following folk treatment methods: drink more chrysanthemum tea (tea is forbidden for 3 hours before going to bed). Spread out some Chinese medicines: calendula, Bidens bipinnata, mint and oregano. 1 kg herbs plus 3~4 liters of water. Soak for 5~ 10 minutes, and then heat it on fire. After the water is boiled for 5 minutes, it is boiled with warm fire 10~ 15 minutes. After filtering, pour the medicine into the bathtub and add cold water to cover the body. Lie still 10 minutes. Wash it every 2~3 days. After a month, your insomnia symptoms will be relieved. In addition, dried laurel (1 serving), fern grass (2/serving) and hops (3/serving) were taken out from the drugstore and sewed in linen bags as pillows. This can also play a role in restoring sleep.

Hope to adopt
