You should sleep with your head facing north and your feet facing south. Because the earth itself has a geomagnetic field, and the direction of the geomagnetic field is north-south, the magnetic field has the property of attracting iron, cobalt and nickel, and the human body contains these three elements, especially the blood contains a lot of iron. Choosing the direction of head north and feet south to fall asleep can conform to the magnetic field lines, make the magnetic field lines pass through the human body smoothly, and minimize the interference of geomagnetic field to the human body.
No matter men, women and children, lying on the right side, slightly bending is the best sleeping position. This is mainly due to human physiological structure. The human heart is located on the left side of the chest, the openings of the gastrointestinal tract are all on the right side, and the liver is also on the right side. If you lie on your right side, you can reduce the pressure on your heart, which is beneficial to the digestion and absorption of food and the metabolism of your body.
