The so-called daily life is the daily activities such as sleeping, walking, getting dressed and covering the quilt. Because these activities are to adapt to the weather and environment, but also have the function of self-repair, so it is also of great significance to health care.

Human activities can be simply divided into two parts: daily activities such as sleeping, talking and walking. The former belongs to yin and the latter belongs to yang. When people go to sleep, the yang gradually drops, the yin gradually becomes stronger, and the function of viscera is weakened. Blood belongs to the liver, yang invades, and essence is hidden in it, so that yin can be nourished for a long time. When people wake up from sleep, the yin will gradually decline, the yang will gradually flourish, the function of viscera will be strengthened, the blood circulation will be accelerated, and the yang will appear, showing various vitality and completing various activities. Sleep is also of great significance to human beings.
