In winter, doors and windows are usually closed at home, which leads to indoor air circulation. Open the window for 20 minutes every morning, noon and evening to keep the indoor air fresh.

2. Go to bed early and get up late

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

3. Exercise properly and sweat.

Exercise muscles properly, sweat and keep fit in winter. Exercise should be combined with exercise, and it is good to run and do exercises as long as you sweat slightly, which is contrary to the way of hiding the sun in winter.

4. Adjust bad mood

The short 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 sunbathing time and go outdoors more.
