1, to prevent the recurrence of the old disease, the old saying goes: "A hundred herbs germinate back, and the old disease germinates." It can be seen that beginning of spring is a season with frequent diseases. The frequently-occurring diseases in spring include pneumonia, hepatitis, meningitis, measles, mumps, allergic asthma, myocardial infarction and psychosis. Therefore, patients with hepatitis, allergic asthma and myocardial infarction should pay special attention to aftercare prevention.

2, don't cut clothes too early, "don't cut clothes in spring, don't wear a hat in autumn." The temperature in early spring hasn't warmed up yet, so don't throw away your winter clothes too early. After wearing cotton-padded clothes for several months in winter, the regulation of body heat production and radiation is in a relatively balanced state with the environmental temperature in winter. From winter to early spring, it is warm and cold, and the temperature changes greatly. If you take off your winter clothes too early, it will be difficult to adapt once the temperature drops, which will reduce your body's resistance. Bacteria attack the body, which is easy to cause various respiratory diseases and infectious diseases in winter and spring.

3. Comb your hair one hundred times a day. The Theory of Health Preservation says, "In spring and March, comb your hair one or two hundred times a week." Combing your hair every day in spring is a good health care method. Because spring is the season when the natural yang rises, at this time, the yang of the human body also conforms to nature and has the characteristics of rising upward and outward, which is manifested in the gradual expansion of pores, vigorous metabolism and rapid growth. Therefore, combing hair in spring just meets the requirements of health preservation in this spring, and plays an important role in promoting qi circulation, relieving depression, dredging qi and blood, and invigorating yang.
