One third of people's life is spent in sleep, and the direction of sleeping will affect their health, because the earth is a huge magnetic field, and its magnetic lines pass through the earth's surface from the North Pole to the South Pole.
If the bioelectric current channel during human sleep is perpendicular to the direction of the earth's magnetic field, then the magnetic force of the earth's magnetic field becomes a strong resistance to human bioelectric current. At this time, in order to restore normal operation and reach a new equilibrium state, human beings have to consume a lot of heat energy to improve their metabolic ability.
If the sleeping direction is east-west, the human body can't get enough energy from the outside, the magnetic force of the magnetic field can't be eliminated in time, and the consumed heat causes the body temperature to rise, then the blood circulation will be abnormal, and symptoms such as insomnia and dizziness will appear.
On the contrary, if you sleep in the north-south direction, the direction of cell current in the human body will be parallel to the direction of the earth's magnetic field lines. At this time, qi and blood run smoothly, sleep deepens and quality improves, which will be beneficial to health.
In order to make you pay attention to your health when you sleep, let's see if you are sleeping in the right direction. People had better sleep with their heads facing north and their feet facing south.
