Environment refers to the natural and social environment that is closely related to human survival, mainly including climate change, geographical factors, living and working environment, etc. People are closely related to the natural and social environment, and if this relationship between “heaven and man” is disrupted, pathological reflections will occur. 1, climate factors The abnormal change of climate in four seasons is an important condition for breeding and spreading evil, leading to the occurrence of diseases, so it is easy to form seasonal diseases. For example, it is easy to catch wind in spring, heat stroke in summer, dryness in autumn and cold in winter. In particular, abnormal weather, such as prolonged drought, waterlogging, hot and cold storms, can not only hurt the body’s vital energy, but also contribute to the spread of tropical diseases and the formation of epidemics. For example, measles, chicken pox, scarlet fever (rotten throat and cholera), etc. occur and are prevalent in winter and spring. In addition, with the different seasons, the body’s yin and yang energy also varies. 2, regional factors Different regions, their climatic characteristics, the nature of soil and water, living customs are different, can affect the physiological characteristics of the population and the occurrence of disease, prone to regional multi-morbidity and common diseases. Such as the northern cold disease, the south more heat or damp heat disease. In some mountainous areas, the population is prone to endemic goiter, etc. In addition, some people live in other places, or foreign travel, each resulting in the body’s resistance to decline, prone to disease, the initial stage often “unconvincing” performance. 3, living and working environment The poor living and working environment has become a common factor in the occurrence of diseases. Such as the work environment of exhaust gas, waste liquid, waste residue, noise, especially water pollution and air pollution, has become a direct pathogenic factors, causing some serious diseases, or acute and chronic poisoning. Poor living conditions, dark and humid, dirty air, mosquito and fly breeding, etc., is also a condition leading to the occurrence and prevalence of disease. 4, social environment People cannot live without society, so people’s political status, economic status, education, family situation, changes in circumstances and interpersonal relationships, etc., also have certain links with the occurrence of disease. These social factors are bound to affect the emotional and spiritual activities of people, and if they cannot adjust to them on their own, they can lead to diseases or become the triggering factors of certain diseases. The “Suwen – sparing five over the theory” said “taste expensive after cheap, although not in the evil, disease from within”, “violent bitter and violent happy, after the first happy bitter, all hurt the essence”.
