The best choice of bed is north-south orientation, smoothness 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 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, 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 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.
Don't leave the bedside empty, against the wall, not by the window, and don't make a bathroom or kitchen behind the bedside.
The bed can't face the door, there can't be a beam press, there can't be a beam press on the bedroom door, the indoor unit of split air-conditioned bedroom can't be hung above the pillow, and the chandelier can't be hung directly above the bedroom. These all belong to the category of beam press.
The bed shouldn't be in front of the mirror. Mirror is a highly reflective object, which easily reflects the energy of human body, especially young couples. If the bedroom mirror is in front of the bed, it is easy to suffer from infertility in the long run.
From bathroom to bed, beware of evil diseases.
