First of all, let's understand what wind, cold, heat, humidity and dryness are. Wind, cold, summer heat, dampness and dryness of fire refer to the "six evils" in Chinese medicine, also known as "six qi", which is a general term for exogenous diseases in Chinese medicine. The so-called climate change in spring, summer, autumn and winter has certain rules and limits. Generally speaking, wind, cold, summer, humidity, dryness and fire are six kinds of climate changes in nature, which are called "six qi". The normal operation of "Six Qi" is beneficial to human metabolism, but if it is too much or too little, the climate is abnormal and the human body's resistance is low, it will become a pathogenic factor, which is called "Six Yin".
Wind, cold, summer, dampness, dryness and fire all cause diseases from the outside, which are mostly related to the seasonal climate, such as windy diseases in the Spring Festival, frequent diseases in summer, frequent diseases in autumn and frequent cold diseases in winter. "Six evils" can cause diseases by acting on the human body alone, or two or three pathogens can invade the human body at the same time, such as damp-heat jaundice, wind-cold-dampness arthralgia, wind-heat cold and so on. And pathogens can be transformed into each other. For example, if the cold is not solved for a long time, it will go deep into the body and turn into heat; If the heat pathogen persists for a long time, it may consume body fluid and turn dry; Or hot weather and so on.
In addition, "six evils" usually enter the body in three ways. In the first case, the skin and muscles are abscessed, that is, the evil is from the outside to the inside; In the second case, from the nose and mouth, that is, from top to bottom; In the third case, both the outside and the top are affected by evil.
As the saying goes, it is easy to hurt the liver in spring, sad in summer, lung in autumn and kidney in winter. Wind, cold, heat, humidity, dryness and fire in climate change have a direct impact on our health. It is the key to avoid the invasion of "six evils" and improve our physique.
