1. Sleep time: Sleep in the four seasons. In spring and summer, you should “sleep late and get up early”, in autumn you should “sleep early and get up early”, and in winter you should “sleep early and get up late”. It is best to get up before sunrise, not too late. 2. Sleep direction. Sleep should be head north to south. The human body is affected by the earth’s magnetic field anytime and anywhere, and the brain is also disturbed by the magnetic field during sleep. Therefore, this can reduce interference. 3. Sleeping posture The body sleeps like a bow, and the burden is light when lying on the right side. Since the heart of the human body is mostly on the left side of the body, lying on the right side can reduce the pressure on the heart. In addition, the two feet are facing each other, the legs are like loops, and the hands are stacked or crossed on the head. The palms are on the top of the head, which can not only invigorate the kidney, but also relax. The head has a good therapeutic effect on insomnia and neurasthenia. 4. Normal sleep time during the sleeping time period. Do not exceed 11 o’clock to 1 o’clock at night (big sleep), and 11 o’clock to 1 o’clock noon (nap) at noon. This is the best time to nourish the kidney. Generally, it is controlled at 8 hours a day Around, the frail and sick people should appropriately increase their sleep time. 5. Sleeping environment. Sleep in a quiet environment. Cell phones and other electronic products should be kept at a certain distance to ensure that there is not too much interference during rest.  . . . . . .

Therefore, the simplest and most effective way to nourish the kidney is to sleep at the right time Sleep well.
