As the saying goes, the year is in the spring. The same applies to the prevention and treatment of diseases in the human body, which should start from spring. According to Chinese medicine, man and nature are in harmony, and the changes in nature will affect the human body. Wind is the main qi of spring. If the wind is too much or not enough, it will become the evil qi that causes diseases. The Su Wen – Theory of Wind says: “Wind is the longest of all diseases.” That is to say, cold, damp, dryness, heat and other evils mostly rely on wind to invade the body. This shows that diseases tend to occur and recur in spring, especially respiratory diseases, rheumatism, rash and other wind-related diseases. In addition, there is also internal wind, which is produced by the dysfunction of the internal organs. The production of internal wind is mainly related to the liver, and the liver is in charge in spring. Therefore, diseases related to internal wind and liver, such as vertigo, hypertension, stroke, hepatitis, liver cirrhosis, etc., are often aggravated in spring. People suffering from these diseases have to prevent recurrence and can make adjustments under the guidance of their doctors. When spring comes, we should pay attention to: (1) keep the living environment hygienic; (2) dress appropriately; (3) strengthen exercise.
