I think yang is nourished in spring and summer, and yin is nourished in autumn and winter. Nourishing Yin in autumn and winter means that you must pay attention to maintaining your important substances and organs such as Yin Meridian, Qi and Blood in autumn and winter, as follows:

First, in daily life, winter health care emphasizes going to bed early and getting up late, and people are advised to go to bed early. It is suggested that they generally fall asleep around 10, and getting up late means that they must do it at sunrise and wait until the sun comes out before going out. Some elderly patients like morning exercises and don't advocate going out early in the cold winter season. They must wait until the sun comes out when they go out for morning exercises, especially for patients with cardiovascular and cerebrovascular diseases. It is forbidden to go out early for morning exercise to prevent sudden contraction of blood vessels and induce cardiovascular and cerebrovascular diseases.

Second, eat more food that nourishes yin, such as food that nourishes yin and nourishes blood, meat, walnuts and kidney, red dates and spleen, and blood can nourish yin and replenish blood, but in winter, you can't blindly nourish yin and injure yang, and some patients who are particularly afraid of cold should nourish yang besides nourishing yin at this time, and eat dog meat and mutton properly, so you should recuperate through diet in winter;

Third, we must maintain emotional stability. Don't get excited or lose your temper. Losing your temper will hurt the vulva due to yin deficiency and internal heat, so try to avoid it.

Fourth, some people with chronic diseases and sub-health are nursed back to health in winter or nursed back to health with cream, which is a good way to keep fit in winter.
