The direction of human sleep is perpendicular to the direction of the earth's magnetic field lines, and the earth's magnetic field will affect the body's bioelectric current. In order to achieve a new equilibrium state, the human body must consume a lot of heat energy to improve its metabolic ability, and sleep is naturally disturbed. Most of the rooms in China are laid with beds in the east-west direction, that is to say, when people sleep, their heads face east or west, perpendicular to the direction of the earth's magnetic field lines. People think that the earth's magnetic field will affect the bioelectric current of human body. In order to achieve a new balance, the human body must consume a lot of heat energy to improve its metabolic ability, and sleep is disturbed, so it is not good to sleep with your head facing east and your feet facing west. But some people say things are better, because the earth often produces instantaneous magnetic field disturbance, which will obviously change the normal behavior of human brain current. If you sleep with your head facing north, your brain will be more seriously affected, and it may even affect the biochemical flowing substances in your body. Scholars believe that the slight pulsation of the earth's magnetic field will inhibit brain current activity, making people dizzy and emotionally unstable. When people sleep with their heads facing east and feet facing west, they will feel calm. Therefore, it is good to sleep with your head facing east and your feet facing west.
Chinese medicine says that the human body should "stand pulse" and "stand qi" during sleep. This "standing" actually means that the direction of qi pulse in the body is consistent with nature, so that blood vessels will be unobstructed. We know that the terrain of our country is high in the west and low in the east. Along the mountain and water potential, the direction of airflow is northwest to southeast. Therefore, I suggest that people sleep with their heads facing northwest and their feet facing southeast, so that the qi pulse of the human body is consistent with nature. The second direction is that the head faces west and the feet face east, or the head faces north and the feet face south.
Sleeping is a very important thing for people. One third of a person's life needs to be spent in sleep. Poor sleep will directly affect your health, but whether this kind of sleep is healthy or not seems to have little to do with the orientation of your head during sleep. What kind of sleeping direction we choose mainly depends on our personal habits, as well as the structure of the house and the direction of the sun, which need to be considered comprehensively.
Actually, it comes down to one thing. If we believe all these statements, we really don't know how to sleep. A good sleeping environment and a good sleeping attitude are more important than anything else.
