Dreams and sleep quality

With the development of modern psychology, the study of dreams has become more and more in-depth, and the mystery that has been shrouded in dreams for thousands of years has been gradually lifted. "Dream sleep helps brain health", which is one of the recent research conclusions. .

Dreaming is a normal and essential physical and psychological phenomenon of the human body. After a person falls asleep, a small part of the brain cells are still active, which is the basis of dreams. According to research, people’s sleep alternates between normal phase sleep and paradoxical sleep. 80% of people awakened from paradoxical sleep are dreaming, and 7% of people awakened from normal phase sleep are dreaming. . A person’s dreams can last for about 1.5 hours every night. Because dreams are accompanied by regular sleep cycles, people who wake up in paradoxical sleep feel more dreams, while those who wake up in normal sleep feel less dreamy. In addition, the dreams that people can remember are mostly when they are about to wake up, and the dreams that have just fallen asleep have long disappeared without a trace. This is another reason why people feel more or less dreams.
　　Why do people dream, and how would they respond if they don't dream? Scientists have done some experiments to block people from dreaming. That is, when the sleeper has dreaming brain waves, he is immediately awakened, and the dream is not allowed to continue. Repeatedly, it turns out that the deprivation of dreams will cause a series of physiological abnormalities in the human body, such as blood pressure, pulse, body temperature, and skin disorders. The electrical response ability has a tendency to increase, and the autonomic nervous system function is weakened. At the same time, it can also cause a series of adverse psychological reactions, such as anxiety, nervousness, irritability, perception hallucinations, memory impairment, disorientation, etc. Obviously, normal dream activity is one of the important factors to ensure the normal vitality of the body. Because people dominate the right hemisphere in dreams, and dominate the left hemisphere after awakening, during the 24-hour day and night activities of the body, awakening and dreaming alternately can achieve neuroregulation and mental activity. dynamic equilibrium. Therefore, dreams are a way of coordinating the balance of the human body's psychological world, especially for people's attention, emotions and cognitive activities.
　　Psychologists believe that human intelligence has great potential. Under normal circumstances, only less than one-fourth is used. The other three-fourths are hidden in the unconscious. Dreaming is a typical unconscious activity. Recombine the existing knowledge, rationally integrate the new knowledge with the old knowledge, and finally store it in the warehouse of 100 million yuan, so that the knowledge becomes one's own wisdom and talent. Dreams can help you to think creatively. Many of the fruitful results of famous scientists and writers also benefit from the enlightenment of dreams.
　　Someone conducted a survey of accomplished scholars at the University of Cambridge in the United Kingdom. As a result, 70% of the scholars believed that their achievements had been inspired by dreams. The University of Geneva in Switzerland conducted a similar survey of 60 mathematicians, and 51 admitted that many difficult questions have been answered in their dreams. If people can't dream, it may lead to disorder of mind and personality to some extent, and even affect the exertion of thinking and inspiration.
　　Dreamless sleep is not only of poor quality; it is also a sign of brain damage or disease. Clinicians have found that some patients with headache and dizziness often complain that they no longer have dreams or rarely dream during their sleep. After diagnosis and examination, it is confirmed that these patients have slight hemorrhage or tumors in the brain. Medical observations show that children with dementia sleep significantly less with dreams than normal children of the same age, elderly people with chronic brain syndrome, and sleep with dreams are significantly less than normal elderly children of the same age.
　　Recent research results have also confirmed this view, that is, dreams are the result of the brain's regulation center balancing the various functions of the body, and dreams are required for the healthy development of the brain and the maintenance of normal thinking. If the brain's regulatory center is damaged, dreams will not be formed, or only some fragments of dreams will appear. If you sleep without dreams for a long time, people should be wary of it. Of course, long-term nightmares are often a sign of physical weakness or suffering from certain diseases.
