After winter, the yang in nature is gradually hidden and the yin is gradually flourishing. At this time, health care should conform to nature, and attention should be paid to maintaining yin in the body in daily life. First of all, we must ensure adequate sleep. For adults, it is best to ensure 8 hours of sleep every day. If you don't get enough sleep at night, you can make up for half an hour to an hour at noon. Adequate sleep can effectively restore energy, nourish yin and cultivate yuan, which is conducive to latent yang in winter and recharge your batteries. In addition, go to bed early and get up late. It is recommended to go to bed no later than 1 1 every night.
