1, the advantage of the head of a bed facing north is that it can conform to geomagnetic attraction. Sleeping with your head facing south or north is good for your physical and mental health. In the human blood circulation system, the direction of aorta and vein is consistent with the direction of human head and feet.
2. When sleeping in the north-south direction, the aorta and the great golden vein are in the same direction as the human statue and the magnetic field lines in the north and south of the earth, so it is easy to fall asleep, and the quality of sleep is very high. Moreover, sleeping in the north-south direction also has certain disease prevention and fitness effects. For example, it can prevent headaches, insomnia, dreaminess and other diseases.
3, the bedside facing north can ensure that the yang of the human body will not be lost during sleep, which is conducive to enhancing physical fitness and resistance. At the same time, it can also prevent the head from being stimulated by western sunshine, which leads to blood rushing straight to the top of the head and affects the stability of sleep.
I hope the above answers can help you.
