There are rules in spring, summer, autumn and winter. Go to bed late and get up early in spring and summer, and go to bed early and get up early in autumn and winter. It is better to get up before sunrise, not too late. Normal people usually sleep about 8 hours a day, and those who are weak and sick should increase their sleep time appropriately.
Head north foot south positioning is accurate. The human body is influenced by the earth's magnetic field anytime and anywhere, and the brain is also disturbed by the magnetic field when sleeping. When people sleep, they take the posture of head north and feet south, so that the magnetic field lines can pass through the human body smoothly, which can minimize the interference of the earth's magnetic field and make sleep more sweet.
Sleep in a relaxed position. Sleeping like a bow is effective, and lying on your side is light. Studies have shown that "sleeping like a bow" can reduce the force of gravity on the human body. Because people's hearts are mostly on the left side of the body, lying to the right side can reduce the pressure on the heart. At the same time, don't put your hands near your heart.
Meridian sleep gets twice the result with half the effort. Whether it is a "late sleeper" or an "early sleeper", people should find their own biological clock to improve the efficiency of sleep. According to the theory of traditional Chinese medicine, the two hours of noon (afternoon 1 1 to the next morning 1) and noon (daytime 1 1 3) are the periods when the daily temperature difference changes the most, so the human body needs proper rest at this time.
Remind you: Chinese medicine "head north and feet south" sleeps more sweetly. This folk prescription comes from the internet. Please follow the doctor's advice before use.
