The alternation of day and night in nature is a natural law – circadian rhythm, human beings in the long evolutionary process, gradually formed a “sunrise and work, sunset and rest; into the night is sleep, into the day is awake” a physiological law – the law of sleep, which is also known as the human biological clock It is also known as the human biological clock. The human body’s sleep pattern is one of the basic physiological laws that human beings harmonize with the laws of nature and rely on to survive and ensure their own health. If the body’s sleep pattern is disturbed for some reasons, sleep disorders will occur, of which insomnia is the most common sleep disorder. In recent years, the incidence of insomnia as a modern disease is very high, the reasons for this are many, in addition to the current pace of social life and competition, people’s poor lifestyle is also one of the main reasons. Therefore, it is very important to understand the triggering factors and clinical characteristics of modern insomnia, to follow the circadian rhythm of nature and the body’s own sleep pattern, and to advocate a scientific way of life and rest to prevent the occurrence of insomnia. Insomnia is a “blunt knife cut”, patients are very painful, in addition to the torture of the disease itself, they will suffer a lot of surrounding people’s lack of understanding and greater psychological pressure, seriously affecting the quality of life and work efficiency. Modern scientific research has confirmed that nearly 90 diseases have a greater correlation with long-term insomnia, and insomnia will not only cause great suffering to the patients themselves, but will also bring negative problems to the whole society, such as increased consumption of medical resources and increased incidence of accidents. After years of clinical practice in insomnia specialties, I deeply appreciate that Chinese medicine has unique advantages in helping insomnia patients to eliminate discomfort, quit dependence on sedative-hypnotics (sleeping pills) and restore normal sleep function. I was born in a family of TCM doctors, and I have inherited the training of my father, Shi Wenji, a veteran TCM doctor, since 1988, I have been engaged in clinical medical research on insomnia, and I am good at using TCM to treat insomnia, depression and anxiety caused by various reasons and to quit the dependence on sedative-hypnotic western drugs (sleeping pills). It is known as “If you have insomnia, look for Shiming”. In order to draw people away from insomnia and effectively reduce the incidence of insomnia, the author combines his many years of clinical practice experience in insomnia specialties and opens the column “Shi Ming talks about insomnia” from today, which is in the form of popular science and says some popular topics about insomnia. If these popular science readings can be slightly beneficial to the general readers, it will be in line with the author’s original intention.
