1. The most comfortable temperature for human body in summer is about 26 ℃. The air conditioner should be turned on 10 minutes after entering the house, and the air conditioner should blow upward. In addition, children's windows should be held every hour to protect the respiratory tract. In summer and autumn, the most comfortable temperature for human body is about 26 ℃. If the temperature is 3 ℃ - 4 ℃ lower, human body will feel a little cold.
2. In addition, due to the different indoor and outdoor environment, the body's regulating ability is out of balance under the relatively extreme temperature for a long time, which will lead to the decrease of immune function and various discomfort symptoms, which is called air conditioning disease in medicine. Therefore, it is suggested that in general, it is best to adjust the air conditioner to about 26 ℃, and the indoor and outdoor temperature difference should not exceed 7 ℃, otherwise, it will increase the burden on the thermoregulation center.
3. Some friends are sweating. When they get home, they turn on the air conditioner and blow hard. This is harmful to their health. Because at this time, the pores are completely open, and it is too late to close, it is easy to make the temperature drop sharply, induce cold and other diseases. Therefore, the air conditioner should be turned on at least 10 minutes after entering the room from the hot outdoor. In addition, when sleeping, the body temperature drops. If the air conditioner is turned on all night long, it is also easy to cause headaches and colds. Before going to bed, the air conditioner must be turned off or set to turn off regularly.
4. When the air conditioner is turned on, the cold air sinks, so the wind is better to blow upward to avoid the direct cold air blowing on the body. People who are close to the air conditioner, it is better to sit in front of the air conditioner, because the cold wind blows on your back and waist from behind, which is more harmful to human body than the face-to-face wind. If you can't move your seat, you'd better prepare a small scarf around your neck. If you sit in office for a long time, such as typing, writing, etc., you can spare parts to wear and take off convenient clothes. When wearing a skirt, you can use a shawl to protect your legs, especially knees. Cold is born from the foot, should stand up from time to time activity, in order to enhance peripheral blood circulation.
5. In addition, turning on the air conditioner will dry the indoor air, and because the air is not circulating, the environment can not be improved, it is easy to make people stuffy nose, dry throat, sneeze, etc. Therefore, we should pay attention to frequent ventilation. It is recommended to open the window once an hour or so for about 15 minutes each time. Especially for some people with respiratory diseases, the air conditioning time should be as short as possible.
