According to experts from the Institute of Environmental Health Monitoring of Chinese Academy of Preventive Medicine, there are strict terms and characteristics of "air-conditioned diseases" abroad, and diseases caused by air-conditioned environment are collectively referred to as "air-conditioned diseases" in China. Air-conditioning diseases mainly occur in the central closed air-conditioning environment, and are also common in household air conditioners. This is because in a closed or relatively closed air-conditioned environment, the air mobility is poor, which leads to the continuous reduction of oxygen content in indoor air. At the same time, the toxic gases volatilized from indoor building materials and the smoke produced by smoking are difficult to be released to the outside through air convection, which leads to the continuous decline of indoor air quality. Indoor temperature and humidity are especially suitable for the reproduction and survival of bacteria because of the closed room and insufficient sunshine. The reproduction of indoor bacteria poses a serious threat to human health.
In such an environment, people are easily infected with diseases caused by microorganisms; Second, the temperature setting is too low, the indoor temperature difference is large, and it is easy to catch a cold when entering and leaving. Symptoms are easy to catch cold, dizziness and poor breathing.
In order to prevent air-conditioning diseases, experts remind users of household air conditioners not to turn on the air conditioner 24 hours a day, not to close the windows all day, the difference between the adjusted temperature and the outdoor temperature should not exceed 7 degrees, and carpets, sheets and sofa cover should be cleaned frequently. At the same time, use the air conditioner correctly, as follows:
1. Always open the window for ventilation to ensure the convection exchange of indoor and outdoor air. Open 1? Shut down after 3 hours, and then open the window to exhaust indoor air and let in fresh outdoor air. To make more use of natural wind to reduce indoor temperature, it is best to use negative ion generator.
2. The room temperature should be kept at about 24℃, and the temperature difference between indoor and outdoor should not exceed 7℃, otherwise entering the room after sweating will increase the burden on the thermoregulation center.
3. The air-conditioned rooms should be kept clean and hygienic, so as to reduce the pollution sources of diseases.
The indoor wind speed should be kept at about 20 cm per second, and the desk must not be placed in the place where the cold wind blows directly, because the airflow there will drop by 3? 4℃。
5. If you sit still for a long time, such as typing, writing, wiring, etc. You should appropriately increase the clothes that are convenient to put on and take off, and cover your knees with towels. And pay attention to intermittent standing activities to improve peripheral blood circulation.
6. When you come home from work, take a hot bath and massage yourself first. It's certainly better if you can exercise properly.
7. After installing air conditioning, pay attention to the elderly and babies, because their temperature perception is poor and their body temperature regulation is poor. Don't pay unnecessary price for enjoyment.
