1, the shape of the bedroom should not be oblique. The shape of the bedroom is suitable for square, not for hypotenuse or polygon. The oblique side is easy to cause the illusion of seeing things, and multiple angles are easy to cause oppression, thus increasing people's mental burden, and in the long run, they are easy to suffer from diseases and accidents. 2. The bedroom should be bright during the day and dark at night. There should be windows in the bedroom. In addition to air circulation, it can also be lit during the day, which makes people feel refreshed. Curtains should be installed in the windows at night to block the outdoor night light, which makes people fall asleep easily. 3. Don't change the bathroom into a bedroom. The pipes of modern buildings are constructed as a whole, so the bathrooms of the whole building are in the same place. If the bathroom is changed into a bedroom, it is equivalent to sleeping in the bathroom upstairs and downstairs, and the bathroom is a wet and unclean place, which will inevitably have an impact on environmental sanitation. In addition, the start of upstairs toilets and water pipes will definitely affect the peace of the owners, so it is harmful to people's physical and mental health. 4, the door can't be facing the bathroom, the bathroom is a place where people excrete, which is easy to produce dirty gas and moisture, so facing the door will have an impact on the air in the bedroom and be harmful to people's health. 5. The door should not be facing the kitchen or the stove fire adjacent to the kitchen, which will easily affect the opposite door, endanger human health and make the work performance unstable. The kitchen is a place to make a fire, which is very hot and dry, and it is not suitable to be adjacent to the bedroom, especially the wall of the bed near the stove. 6. the door can't reflect the mirror, and the mirror will shine the night light into the bedroom when facing the door. If the host has too many noctilucent reflections when sleeping at night, it will affect the quality of sleep and thus affect his health. 7. Mirrors and floor-to-ceiling doors and windows should not be imaged on the bed mirror, so they should not be imaged on the bed. Especially when people wake up from sleep and are not conscious, they are easily frightened by themselves reflected in the mirror or French window. 8. Don't face the door on the bed or bedside. When sleeping, safety, quietness and stability are the most important. The door is the only place to get in and out of the room, so don't face the bed or the head of the bed. Otherwise, people who sleep in bed are prone to insecurity and are harmful to their health. 9, the head of a bed should not be under the beam, the ceiling should be flat, avoid the beam. The beam is easy to feel heavy psychologically, especially when people sleep under the beam, they will feel great pressure, which will cause mental oppression and affect their health and career. 10, too many plants should not be placed in the bedroom. Too many flowers and plants are easy to gather shade, and plants absorb oxygen and release carbon dioxide at night, which is easy to affect people's health.
