What are the feng shui taboos of headboard?

Bedroom feng shui taboo should pay attention to the following points; 1. No matter where the bed is placed, the key is to let the sleeper see the doors and windows of the bedroom from the bed, and at dawn, the sun will shine on the bed, which will help absorb the energy of nature. 2, the bed can not face the door, so as not to be seen at a glance, no privacy and security, but also affect the rest. If the door collides, you can block the door with a screen, which not only blocks the collision of the bed door, but also maintains the privacy of the bedroom. 3. The best choice of the bed is the north-south direction and geomagnetic attraction. Sleeping with your head facing south or north is good for your health, because the aorta and great veins are the most important in the human blood circulation system, and their directions are consistent with the direction of your head and feet. When the human body is in the north-south sleeping direction, the directions of aorta and vein, the sleeping direction of human body and the north-south magnetic field lines of the earth are the same. At this time, people are the easiest to fall asleep and the quality of sleep is the highest, so the north-south sleeping direction has certain disease prevention and health care functions. The bedside should not face west, because the earth rotates from west to east. 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. 4. The bedside should not be empty. The bedside should be against the wall, not by the window. If the bed is not against the wall, there must be a headboard at the head of the bed, so that the head will not be suspended. Moreover, the back of the bed is not a bathroom or a kitchen. 5. Don't use the beam to press the bed, so as not to cause depression. It is also harmful to people's physical and mental health. This situation also includes that the bedroom door can't be pressed by the beam, the indoor unit of the split air-conditioned bedroom can't be hung above the pillow position, and the chandelier can't be hung directly above the bedroom, all of which belong to the category of beam press.
