When a person sleeps, he always has nightmares. Why? Why is it normal for people to dream when they sleep? According to relevant data, people spend about 1/3 of their lives sleeping and 1/5 dreaming. If a person has lived for 75 years, he has been dreaming for 15 years. Do you know why people dream? As the saying goes, "I think about it day and night, and I dream at night." The root of dreams is actually the activity of the brain. We know that the human brain can constantly respond to the outside world when it is awake. In the evening, when people are tired, they go to bed. During most of sleep, brain waves and eye movements are the same as when waking up, and only the body muscles are in a state of inhibition. At this time, what we experienced, saw or thought during the day will reappear in our dreams. The content of dreaming is often related to what you get during the day or what you get when you sleep. If you think too much about something during the day, you will dream about it at night, or even if you have never thought about someone or something, because you have experienced it before, some nerve cells in your brain will "recall" the past when you sleep at night, so you will dream about it. When sleeping, the external * * * will make the brain react incorrectly, thus having all kinds of weird dreams. In addition, the * * * and pathological changes of various organs in the body will also cause similar scenes in dreams. For example, if you are in a hurry, you will dream that you can't find the toilet anywhere. Dreaming is a physiological phenomenon. Normal dreaming will not affect your health, but if you often have nightmares or strange dreams that affect your sleep, you should see a doctor and treat them in time. After people fall asleep, a small number of brain cells are still active, which is the basis of dreaming. Why do people dream and what happens if they don't dream? Normal dream activity is one of the important factors to ensure the normal vitality of the body. Pavlov said: "dreaming is a trace, mostly the excitement of old traces." Scientists have done some experiments to stop people from dreaming. That is to say, when the sleeper has a dream brainwave, he is immediately awakened to stop his dream from continuing, and so on. The results show that deprivation of dreams will lead to a series of physiological abnormalities of human body, such as blood pressure, pulse, body temperature and skin electrical response ability, and the function of autonomic nervous system will be weakened. At the same time, it will also cause a series of adverse psychological reactions, such as anxiety, tension, irritability, perceptual hallucinations, memory disorders, irritability and so on. When a person's eyes turn, it means that the sleeper is dreaming. Nowadays, when people study the physiology of dreams, the number and length of dreams are measured by the number and time of eye movements. But some people say that people's sleep is always in a rhythmic cycle, that is, in the alternation of rapid eye movement sleep and slow wave sleep. Slow-wave sleep is a quiet sleep state, while rapid eye movement sleep causes people's eyes to rotate rapidly because of irregular breathing and heart rhythm. Obviously, normal dream activity is one of the important factors to ensure the normal vitality of the body. Dreams are a way to coordinate the balance of human psychological world. Because people are dominated by the activities of the right hemisphere in dreams and the activities of the left hemisphere after waking up, waking up and dreams appear alternately during the 24-hour day and night activities of the body, which can achieve a dynamic balance between neural regulation and mental activities. Therefore, dreams are a way to balance people's psychological world, especially for people's attention, emotions and cognitive activities. Dreamless sleep is not only of poor quality, but also a sign of brain injury or disease. The recent research results on the exploration of dreaming also confirm this view, that is, dreams are the result of the brain's regulation center balancing various functions of the body, and dreams are the need for the healthy development of the brain and the maintenance of normal thinking. If the brain's regulatory center is damaged, dreams will not form, or only some incomplete dream fragments will appear. If you sleep for a long time without dreams, it is worth people's vigilance. Of course, if you have nightmares for a long time, it is often a sign of weakness or some diseases. More rigorous scientific research on dreaming began in17th century. 1886 Robert, an expert on dreams, believes that people are exposed to countless information intentionally or unintentionally in their daily activities, and they must release some of these information through dreams. This is the famous theory that "dreaming is to forget", which began to be popular again in the1980s one hundred years later. Shortly after Robert, Freud's theory of psychological dream interpretation appeared again. Freud believed that people constantly have desires and desires, which are expressed and released through various disguises and deformations in dreams, so that they will not break into people's consciousness and wake people up. That is to say, dreams can help people eliminate those desires and desires that are unacceptable to the conscious system and are the guardians of sleep protection. Freud's theory was popular from the beginning of this century to the 1960s. Later, the study of dreams in the world slowly left the field of psychology and entered the biological laboratory. Since then, dreaming has been regarded as a biological phenomenon. Michel Jouvet, a neurobiologist at the Dream Research Laboratory in Lyon, France, is an internationally renowned expert in dream research. Jouvet defined dreaming as "parasomnia" in 1959. He found through EEG test that people have 5 ~ 20 minutes of dreamy sleep every 90 minutes, and the signals reflected on the instrument screen are different, showing the changes of brain activity during sleep. If the subject is awakened when the EEG shows dreamless sleep, he will say that there is no dream; If you wake him up when he shows dreamy sleep, he will remember the dream he just had. In addition, the researchers used X-ray tomography technology to test and found that the image of the brain in dreamy sleep stage is close to that in waking state. Interestingly, the researchers found that dreaming is not unique to human beings, and birds and all mammals also dream. In the late 1970s, a scientist discovered through experiments on mice that dreamy sleep was also related to memory. Dreamy mice can remember their experiences better than those deprived of dream sleep, but the results of this study are not applicable to humans, because doctors use an inhibitor called monoamine oxidase when treating patients with mental depression, which can completely cancel people's dream sleep, but will not cause memory impairment. Wei Ru, a French expert on dreams, believes that dreams are determined by genetic factors. He compared the letters and numbers that mice emit when they sleep in dreams, and found that mice with the same genetic system have similar letters and numbers. A recent experiment by Bulga, a researcher at the University of Colorado in the United States, confirmed this theory. Bulga studied identical twins and found that twins who were raised by two different families in different places after birth actually had similar dream experiences, which proved that human dream performance is genetic memory. In addition, there is a recent report on dreaming research in the just published American Science Weekly. The author of this report, a cooperative team of the Washington Institute of Neuroscience and the National Institute of Health in Bocaistar, Maryland, tested more than a dozen people who accepted the experiment with a high-performance neural tomography camera and found that the blood circulation in this specific area of their cerebral cortex was abnormally accelerated during the dream sleep stage. The researchers found that the visual nervous system responsible for seeing dream scenes and external visual scenes in the brain originally existed independently. According to the report, after seeing that the internal visual system of dreams has been proved to exist independently, it can explain why we have inflated emotions in dreams and why we can accept unreasonable eccentric plots and chaotic concepts of time and space.
Why do I always suffer from insomnia when I sleep alone? It may be because of a person's fear and loneliness. Don't watch horror movies and novels before going to bed. Exercise more during the day and fall asleep when you are tired at night.
Insomnia, in fact, is mostly caused by the bad habits of your usual life. Then you have to get rid of bad habits, and it is the key to cultivate good life rules. The health therapist said: Go to sleep first!
Suggestion:
1. Thinking while sleeping will only aggravate insomnia. In order to distract yourself, you can count, or watch TV with a timer and go to sleep. After going to bed, close your eyes first, then open your eyes slightly to keep in touch with the outside world. Although mental activity is still in operation, the tension of sympathetic nerve activity has been greatly reduced, which induces the human body to gradually enter a sleepy state. ;
Don't put an alarm clock in the bedroom. The ticking of the alarm clock and the dazzling light from the hands mean that people who sleep normally can't sleep well. Physical exercise and regular activities contribute to sleep, but those who suffer from insomnia should pay attention. Do not do strenuous exercise within two hours before going to bed;
4. Don't drink coffee, tea and alcoholic drinks at night, and don't smoke, because these things are exciting;
Going to bed and getting up regularly can play a calming role. Therefore, insomniacs should sleep at a fixed time and try to get up at a fixed time, even on weekends and holidays; To develop a good sleeping position, the sleeping position is of course comfortable and can vary from person to person. However, it is better to sleep on your side. This sleeping position is conducive to the whole body to relax and sleep peacefully.
6. Eating too much at dinner will affect sleep, so avoid eating too much at dinner; Drink more hot milk and eat banana whole wheat bread. 7. Taking a nap may be a pleasure for some people, but it is not allowed for insomnia patients. If someone sleeps during the day, then he shouldn't complain that he can't sleep at night. Also, it is best to take a warm bath and listen to a light music before going to bed, so that the wonderful melody can accompany you to sleep and relax your body and mind completely. 8. Find a place where you feel most comfortable, have a rest, or take a nap. Close your eyes slowly and listen to the slow light music. Imagine you are in a beautiful place.

Why do you always feel chest tightness and insomnia when you sleep? Insomnia means that it is often difficult to fall asleep or wake up from time to time, unfamiliar with sleep, unable to sleep after waking up, unable to sleep all night, etc. Its behavior is accompanied by dizziness, headache, palpitation, forgetfulness and other symptoms, which brings great trouble to people's daily life. People who don't sleep well are mostly caused by the problems at the end, such as anxiety, tension, fear and excitement, which will lead to insomnia. Some drugs containing thyroid preparations, cannabis leaves, caffeine and alcohol can also affect normal sleep. Insomnia can often be caused by physical discomfort or diseases, such as asthma, excessive fatigue and excessive work pressure. Insomniacs usually have regular physical exercise, which can reduce mental stress and balance their mentality, so as to sleep well. If insomnia is caused by taking certain drugs, you can consult a doctor. Insomnia patients should pay attention to the following problems in diet and health care. The diet should be light and digestible, and eat more grains, beans, vegetables, fruits, fish, lean meat and milk. Lily, lotus seeds, walnuts, celery and other foods can be used to improve sleep. Avoid foods high in animal fat, brain stem and cholesterol. Drink less caffeinated drinks, such as coffee, tea and cola drinks, and drink more fruit and vegetable juices. Milk, a kind of food to help sleep, is nutritious and contains two hypnotic substances. One of them is the raw material for making S- hydroxytryptamine, which can promote the synthesis of sleep serotonin. Tryptophan, because L- tryptophan, often only needs a glass of milk to make people fall asleep. The other is peptides that can regulate the function of the body, among which there are several "opioid peptides", which can make the whole body feel comfortable, help to fall asleep, relieve fatigue and are not addictive. The hypnotic effect of milk on neurasthenia caused by physical weakness is particularly obvious. Therefore, you can drink a glass of warm milk before going to bed. Honey honey has the functions of invigorating the middle energizer, invigorating qi, calming the five internal organs, and harmonizing various medicines, and has a significant effect on insomnia. Take 1-3 teaspoons of honey, add jujube and sugar to the water, and have a drink before going to bed. Walnut Walnut can be used to treat neurasthenia, amnesia, insomnia and dreaminess. Use walnut kernel with 50g of black sesame seeds and 50g of mulberry leaves to mash, and take 15g each time. Sunflower seed Sunflower seed contains linoleic acid, various amino acids and vitamins, which can regulate the normal metabolism of human brain cells and improve the function of nerve center. Eating a handful of melon seeds every night can help you sleep. Xiaomi Xiaomi has the effect of "strengthening the stomach, harmonizing the spleen and sleeping peacefully". Studies have found that millet is rich in tryptophan, which can temporarily inhibit brain thinking activities and make people feel sleepy. Drinking a bowl of millet porridge before going to bed can make people sleep well. Jujube Jujube has a significant effect on dreaminess and mental trance. The quality of sleep can be improved by boiling jujube in water and simmering donkey-hide gelatin into paste. Small fish and pumpkin have certain effects on insomnia. In addition, celery soup has a good effect, so you can eat more at ordinary times. In addition, proper relaxation exercise can help blood circulation and promote sleep. Taking a hot bath before going to bed and then going to bed will also help you sleep. ^^

When is the best time for a person to sleep? The sleep time of ordinary people should be distinguished according to their age. Newborns need to sleep at least 20 hours a day, infants need 14 ~ 15 hours, preschool children need 12 hours, primary school students need 10 hours, middle school students need 9 hours, college students need 8 hours, and the elderly need 6 ~ 7 hours because of their slow metabolism. People who fall asleep quickly and deeply generally don't dream or dream less, and they can regain their energy after sleeping for 5 to 6 hours or less; Those who fall asleep slowly and have a light sleep often have nightmares. Even if they sleep for 10 hours, they still don't feel refreshed. Therefore, we should pay attention to improving the quality of sleep, and we can't just make up for it by extending the time. Sleep quality is closely related to sleep environment. Generally speaking, you can have a good sleep at 15 to 24 degrees Celsius. Too cold or too hot often leads to sleep disorders. Sleeping too long at night is not good for life. At present, the average sleep time of men at night is 7.58 hours, and that of women is 7. 12 hours. People who sleep between 6.5 and 7.5 hours a night live the longest. According to the human biological clock, it is more beneficial to sleep around 1 1 o'clock, because brain activity and metabolism need to be fully rested between 10 and 2 o'clock.
Adults usually sleep for 2 hours, and children usually sleep 1 hour to one and a half hours.
What is a nightmare? Why does a person always wake up when sleeping? Haha, I have had this situation. When it was a little brighter, I felt as if I saw something, but I wasn't sure whether I was dreaming or waking up. I can't move my body, or I feel that my hands and feet can't move when I sleep at night. It's so painful. It is said that this is because my body has entered a state of fatigue when I sleep, but my brain is still awake, indicating that the two of them do not cooperate well. Mainly to develop a healthy lifestyle and ensure adequate sleep. Also, drink less water before going to bed and don't force yourself when you don't want to sleep. Because you may have nightmares when you fall asleep, but the probability of hallucinations is relatively low. The correct sleeping position is also very important. Generally, people who have nightmares like to sleep upside down, that is, with their chests down and their heads covered. Lying on your back, being covered with a thick quilt or putting your hands on your chest, being too nervous during the day and overeating at dinner are all the reasons for nightmares. Sleep on your side and avoid the above reasons, so you won't have nightmares. There are several ways to wake yourself up when you have nightmares. It is almost impossible to do things with your hands and feet in a nightmare, but you can try shaking your head. Also, don't sleep there motionless after waking up, you may have nightmares again. It's best to turn on the light and get up immediately, drink some water, sit down and go back to sleep when your mind is clear. The diagnosis of nightmares in traditional Chinese medicine refers to screaming or hallucinating that there is a heavy object pressing on the body during sleep, unable to move, unable to exhale, panic and holding breath in the chest, which are common clinical symptoms. Its occurrence is related to physical weakness, fatigue, anemia, hypotension and emotional factors such as depression, anger and anger. Because people's blood pressure is further reduced during sleep, it leads to cardiac and cerebral ischemia and reduced oxygen supply, and the motor center of cerebral cortex enters the inhibitory state before the sensory center; Or it is because peripheral nerves enter a state of inhibition faster than central nerves, resulting in nightmares of wakefulness and motor paralysis. Traditional Chinese medicine believes that nightmares are caused by deficiency of both qi and blood, poor circulation of qi and blood, qi stagnation and blood stasis, and obstruction of meridians. Therefore, for the prevention and treatment of nightmares, we should first pay attention to strengthening nutrition, enhancing physical fitness, preventing excessive fatigue, treating anemia, and avoiding negative emotions such as depression, anger and anger. For patients with hypotension, 20 grams of Radix Astragali, Radix Codonopsis, Radix Angelicae Sinensis and Radix Glycyrrhizae can be decocted in water for half a month. Most patients can recover their blood pressure within a course of treatment. In addition, the prevention and treatment of nightmares can still be guided. The specific method is to bend your thumb and hold it with the other four fingers. Especially when you fall asleep, you should form a habit and make unremitting efforts to gradually reduce the onset of nightmares. But now I'm used to it, but I think having strange dreams can help me relieve stress. This is a strange trip. Don't worry too much, think too much and care too much. But try to make things worse and learn to appreciate them when dreaming.
