Traditional doors are only used as isolation facilities for ingress and egress, and do not have the function of air exchange. However, in modern living environments, indoor air quality is often poor due to closed doors and windows, and the release of harmful gases from furniture and decoration materials. Long-term living in such an environment will have adverse effects on human health.

[0003] According to existing research, the carbon dioxide concentration and the human body's physiological reactions are as follows: 350-1000ppm: the air is fresh and breathing is smooth; 1000-2000ppm: the air feels turbid and you begin to feel drowsy; 2000-5000ppm: you feel headache, drowsiness, dullness, inability to concentrate, accelerated heartbeat, and mild nausea; and after sleeping in a closed room for a night, the carbon dioxide concentration will reach a maximum of about 2000ppm in the morning, so aerobic sleep is particularly important for a person's physical and mental health.

[0004] Since the bedroom space of urban families is generally small, the air exchange rate between the bedroom and the outside world is low. The carbon dioxide concentration in the room will become higher and higher during sleep. When sleeping with the windows closed at night, the carbon dioxide concentration in the air will gradually increase from evening to morning. This will cause many people with high blood pressure, cardiovascular disease, heart disease and other diseases to have difficulty breathing in the second half of the night.
