The first Affiliated Hospital of Henan College of Traditional Chinese Medicine, Department of Pediatrics, Yan Yongbin (The first Affiliated Hospital of Henan College of Traditional Chinese Medicine, Yan Yongbin) “Sickness begins with overuse” from the “Su Wen – the meridians and veins of the other” view of disease ┄ reading “Su Wen – the meridians and veins of the other” experience. It is a kind of understanding of Chinese medicine about human morbidity, that is, the problem of “degree”. It emphasizes that factors such as the four seasons, yin and yang, the seven emotions, diet, labor and leisure are both pathogenic and non-pathogenic, and the occurrence of disease is the result of the “overuse” of the above factors, which is a manifestation of the imbalance between life activities and the internal and external environment of the organism. The key to the disease or non-disease of the human body is whether it is “overused” in relation to various factors inside and outside the body, that is, whether it is “moderate”. It is an important principle to guide people to prevent and treat diseases, and has important theoretical and clinical significance. First, the changes of yin and yang in the four seasons are closely related to the life activities of the human body, “Ling Shu – the dew of the year”, “people and heaven and earth also, and the sun and moon corresponding also. Lv’s Spring and Autumn Period – The End of Numbers”, “The four seasons and the changes of all things are not only beneficial, but also harmful”. If the changes of yin and yang in the four seasons are orderly, wind, cold, summer and humidity promote the growth and development of all things, which is the “six qi” of “for the benefit”; on the contrary, climate change is out of order, appearing too much, not enough, too rapid or not its On the other hand, when the climate changes abnormally, such as too much, not enough, too fast or not at the right time, the human body cannot adapt to it and it appears as “overuse”, that is “six perversions” that are “harmful”. Therefore, the “overuse” of the six qi and the body’s relationship is out of order, manifesting as a pathogenic factor. Secondly, the seven emotions are a way of communication between the human body and the external environment, as well as the emotional response of the human body to harmonize with external objective things. The seven emotions are born in the five viscera, “Suwen – Yin and Yang Ying Xiang Daxue”, “people have five organs into five qi, to produce happiness, anger, sadness and fear”. At the same time, the normal activities of the seven emotions are conducive to the function of the five organs. Good external stimulation can produce optimism and a relaxed state of mind, which can make the body’s qi and blood peace, the internal organs function in harmony. However, if there is a sudden, strong or long-term persistent emotional stimulation, beyond the normal physiological activities of the body itself, so that the body can not adapt to it, and the performance of “over with”, it can lead to Qi and blood rebellion, visceral damage and become a pathogenic factor. It can be seen that only the seven emotions that exceed a certain “degree” is a pathogenic factor. Third, diet is the basic condition for the survival of the individual. In the Suwen Paralysis, “If you eat and drink, your intestines and stomach will be injured”, it means that there is also a “degree” of diet, and there is also duality. Diet is appropriate in moderation, but hunger and satiety can cause disease. Excessive hunger is no source of Qi and blood biochemistry, and in the long run, the Qi and blood will decline and become sick. On the contrary, excessive intake can lead to dietary obstruction and damage to the spleen and stomach. Finally, labor and leisure is the most accurate response to the idea of “sickness starts from overuse”. Labor and rest are the basic activities of the organism, and the combination of labor and rest is necessary to maintain health, but there is also a “degree”. Overwork can deplete the qi and hurt the yin and damage the internal organs; overwork can also make the qi and blood is not smooth, the spleen and stomach dysfunction. The seven emotions and six desires, the birth of children is not only the physiological mechanism of the human body, but also the physiological needs of the human body. Normal male and female pleasure is not only harmless, but can promote the physical and mental health of people. Indulgence in sexual intercourse can directly kill the kidney essence and lead to old age and short life. As the “Su Wen – Yin and Yang should be the elephant in the room” cloud “can know the seven losses and eight benefits, the two adjustable, do not know to use this, it is early decline of the section also. In conclusion, the disease concept of “sickness starts from overuse” is based on a holistic concept, which dialectically analyzes the causes of disease and recognizes disease from the perspective of the relationship between human beings and the external environment such as nature and society, as well as the internal factors such as human beings and their emotions, diet, living, labor and fatigue. Various factors that are closely related to human life activities are neither indispensable nor excessive.
