2. if the bed is placed in the east-west direction, it is best to have the head of the bed in the east, the head in the east and the feet in the west. Because the earth turns from west to east, the flow direction of human blood is consistent with the rotation direction of the earth, and people are easy to fall asleep, especially those with cerebral thrombosis. Blood flows to the brain, which helps the brain to supply oxygen.
Whether it is a bed in the south or a kang in the north, it should be placed or built in the north-south direction, so that the body will not be disturbed by geomagnetic field.
As we know, the earth where human beings live is a huge magnetic field, and its magnetic lines pass through the earth's surface from the North Pole to the South Pole. When the human body is sleeping, the biological current channel is perpendicular to the direction of the earth's magnetic field lines, so the magnetic force of the earth's magnetic field becomes a strong resistance to the human body's biological current. In order to restore normal operation and reach a new equilibrium state, the human body has to consume a lot of heat energy to improve its metabolic capacity. ?
When the sleeping direction is "east-west", the 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 haunts the whole body in the form of heat, which leads to the increase of body temperature, so the qi and blood operation will be abnormal and morbid, usually manifested as dizziness, irritability, insomnia, cervical pain and other symptoms.
If the "north-south" sleeping direction is adopted, the direction of cell current in the human body can be parallel to the direction of the earth's magnetic field lines, and the arrangement of biological macromolecules in the human body has directionality. In this way, qi and blood run smoothly, metabolism is reduced, energy consumption is sharply reduced, and slow waves and fast waves are coordinated during sleep, which can deepen sleep depth, thus improving sleep quality and benefiting physical and mental health. " ?
The favorable reason for sleeping with your head facing south or north is that there is a large and weak magnetic field between the south pole and the north pole of the earth. If the human body follows the geomagnetic north-south direction for a long time, it can make human organ cells orderly, adjust and improve organ functions.
