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. You can't rely on the door of the bed. If you accommodate the limited space in the bedroom and put the bed at the gate, you will make a bedroom taboo. It is best to choose the north-south direction of the bed, which is in line with 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 orientation of aorta and great vein, the sleeping direction of the human body and the direction of 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 autobiography of the earth is from east to west. If the head faces west, the blood often goes straight to the top of the head, and the sleep is unstable; If you sleep with your head facing east, you will feel a sense of peace. The bedside should be real, not 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 to prevent the head from hanging. Don't make a bathroom or kitchen behind the head of the bed. Don't point the bed at the door, so as not to be seen by outsiders, which will have no privacy and security and affect the rest. The bed should not be in front of the mirror, because people get up in the middle of the night and are easily frightened by the images in the mirror, which leads to dizziness; Secondly, when people fall asleep, the energy of qi is the weakest, and the mirror is a highly reflective object, which easily reflects the energy of the human body, especially young couples. If the bedroom mirror is facing the bed, it is easy to suffer from infertility in the long run.
