The direction of the head of a bed is feng shui towards the head of a bed.

1, the direction of the bed is north-south, and it is best for people to sleep with their heads north and feet south. According to the principle of the earth's magnetic field, it is best to spread the bed in the north-south direction at home, and people's sleeping heads face north and feet face south, which is beneficial to their health.

2. The earth is a huge magnetic field, and its magnetic field lines come out from the North Pole and cross the surface of the earth into the South Pole. The biological current channel of human body is perpendicular to the direction of the earth's magnetic field line, and the magnetic force of the earth's magnetic field becomes a resistance of human body's biological current. To restore normal operation and reach a new equilibrium state, it is necessary to consume a lot of calories and improve metabolic capacity. In the long run, when the body can't get enough energy from the outside, the blood circulation will be abnormal and morbid. At the same time, in order to achieve a new equilibrium state, the consumed energy surrounds the bed in the form of heat, which makes the temperature rise when sleeping and makes it difficult to fall asleep.
