If it is about 3℃-4℃ lower, the human body will feel a little cold. In addition, due to the different indoor and outdoor environments, long-term exposure to relatively extreme temperatures, the body's adjustment ability is unbalanced, which will lead to the decline of immune function and various discomfort symptoms over time, which is called air conditioning disease in medicine. Therefore, it is suggested that under normal circumstances, it is best to adjust the air conditioner to about 26℃, and the temperature difference between indoor and outdoor should not exceed 7℃, otherwise it will increase the burden on the thermoregulation center. Some friends broke out in a sweat and turned on the air conditioner immediately when they got home, which was harmful to their health. Because the pores have been completely opened at this time, it is too late to close them, which is easy to cause a sharp drop in body temperature and induce diseases such as colds. So it takes at least 10 minutes to turn on the air conditioner when you enter the room from the hot outdoor. In addition, when sleeping, the body temperature drops. If the air conditioner is turned on all night, it is easy to cause headaches and colds. Be sure to turn off the air conditioner before going to bed, or set it to turn off regularly. When the air conditioner is turned on, the cold air sinks, and the wind is best blown upward to avoid the cold air blowing directly on the body. People close to the air conditioner, it is best to sit facing the air conditioner, because the cold wind blows your back and waist from behind, which is more harmful to the human body than the oncoming wind. Friends who sit in the office, if their seats can't move, had better prepare a small silk scarf around their necks. If you sit in the office for a long time, such as typing and writing. You might as well wear spare parts and convenient clothes. When wearing a skirt, you can use a shawl to protect your legs, especially your knees. Cold comes from the feet, so stand up and exercise from time to time to improve peripheral blood circulation. In addition, turning on the air conditioner will make the indoor air dry. Because the air is not circulating, the environment will not be improved, which is easy to make people stuffy, dry throat and sneeze. So pay attention to frequent ventilation. It is recommended to open the window once every 1 hour, and each time is about 15 minutes. Especially for some people with respiratory diseases, the shorter the time to turn on the air conditioner, the better.
