In winter, doors and windows are usually closed at home, resulting in indoor air circulation. Windows should be opened for 20 minutes every morning, noon and evening to keep indoor air fresh.

2. Go to bed early and get up late

After beginning of winter, the aftercare of daily life should focus on "keeping yang". People should go to bed early and should not get up too early in the morning, so as to ensure adequate sleep time.

3. Exercise properly and sweat.

In winter, you should properly exercise your muscles and sweat, so as to strengthen your body. Exercise should be combined with movement, and running and doing exercises should only be slightly like sweating, which is contrary to the way of hiding yang in winter.

4. Regulate bad emotions

Shorter sunshine time in winter is also easy to make people feel depressed. When night comes, melatonin secretion in the pineal gland of human brain increases, which will affect people's mood. During the day, you can appropriately increase the time of sunbathing and go outdoors more.
