1, to prevent the recurrence of old diseases:

There is an old saying: "A hundred herbs germinate, and old diseases germinate." 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;

"No clothes in spring, no hats 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.
