1, the best choice of bed is the north-south direction, which is in harmony with geomagnetic attraction. When people sleep with their heads facing south or north, aorta and great veins are the most important in human blood circulation system, and their directions are consistent with those of human head and feet, which is beneficial to health. When the human body is in the north-south sleeping direction, the direction of aorta and great vein, the direction of human sleeping direction and the direction of magnetic field lines in the north and south of the earth are the same, so people are the easiest to fall asleep and have the highest sleep quality. The bedside should not face west, because the earth rotates from east to west. If the head is facing west, the blood tends to go straight to the top of the head and sleep is unstable. If you sleep with your head facing east, you will feel a sense of peace.
2, the bedside can not rely on the door, if you accommodate the limited space of the bedroom, put the bed on the edge of the gate, it will make the bedroom taboo.
3. The orientation of the bedside should be suitable for receiving direct light, preferably facing south or south. Generally speaking, sunlight can penetrate for 2-3 hours a day, which is beneficial to eliminate indoor moisture, kill bacteria, adjust indoor temperature and accelerate air flow.
4. Beds should not be crossed, and lighting should not be placed on the ceiling above, otherwise it will lead to problems caused by diseases such as stress and headache.
