1, mainly nourishing yin and moistening dryness. As the saying goes, "medicine is better than food." In winter, food supplement is particularly important. Hong Min suggested that the diet should be heavy after winter, and the main ingredients should be nourishing yin. The basic principle of TCM four seasons health preservation is "nourishing yang in spring and summer, nourishing yin in autumn and winter". This is because in autumn and winter, Yang is hidden and Yin essence is hidden. It is better to follow the trend and nourish yin than at other times. Just like a thirsty flower, nourishing yin in spring and summer is like watering flowers at noon, and more than half of the water poured will be evaporated, while nourishing yin in autumn and winter is like watering flowers at night, and the same amount of water will not be evaporated, but will be nourished by morning dew. Water is the source of Yin Qi. Therefore, it is advisable to drink more warm water in winter, while nourishing yin and moistening dryness. In addition, you can also choose nourishing food, such as Radix Adenophorae, Polygonatum odoratum, lily, fig, tremella, Lycium barbarum, soft-shelled turtle, Siraitia grosvenorii, etc., to make soup or stew.

2. Quiet and carefree. From "beginning of winter" to "beginning of spring", it is called "Winter March", which is the coldest season in a year. Although some areas are not cold, we should adapt to natural changes. After winter, daily life should be nursed back to normal. Emotionally, after winter, the mood should be peaceful and quiet, so as to make the air inward and help to raise Tibet. Everything withers in winter, which often makes people emotional and unhappy. The best way to change this bad mood is to take part in more recreational activities, such as dancing, playing chess, drawing, practicing calligraphy and enjoying music. It can eliminate the depression in winter and cheer up the spirit.

3. Go to bed early and get up late, and postpone morning exercises. In daily life, it is recommended to go to bed early and get up late, and do it at sunrise to ensure adequate sleep. You can also sleep in properly, which is conducive to the hiding of yang and the accumulation of yin essence. Young people should avoid rich nightlife and going to bed too late. Old people should avoid getting up too early when doing morning exercises.
