2. When sleeping, you can sleep in the east-west direction or in the north-south direction, but you should sleep in the east-west direction with your head facing east; Sleep with your head facing south.
3. Sleep direction: head facing south and feet facing north. Because the direction of the earth's magnetic field is from south to north. Therefore, 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, their heads face south and their feet face north, so that the magnetic lines of force can pass through the human body smoothly and the interference of the earth's magnetic field to the human body can be minimized.
4, sleeping position: sleeping position is as good as a bow, lying on your side is light. Studies have shown that "sleeping like a bow" can just reduce the force of the center of the earth 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.
