In addition, it is best not to look at the mirror and the door, and try to avoid the window. The orientation of the bedside, according to the principle of the earth's magnetic field, is most beneficial to the human body.
Because the magnetic lines in the earth's magnetic field point from the North Pole to the South Pole, the human body is in a parallel state with these magnetic lines, which will be less affected, which is beneficial to human health and helps sleep. If it is in a vertical state, then the magnetic field lines will become the resistance of the human body, which is not conducive to the balance of metabolism, and it is easy to damage health in the long run.
