Is living in an air-conditioned room harmful to your health?

Being in an air-conditioned room for a long time will lead to the closure of sweat glands and affect normal metabolism and secretion. Once the cold air breaks through the fragile "defense line" of the respiratory tract, cold symptoms such as cough, sneezing and runny nose appear, that is, upper respiratory diseases. This kind of cold is usually called a cold. On the one hand, because of frequent access to air-conditioned rooms, the body can not adapt to the uneven temperature; Second, because the air-conditioned rooms are closed, there are many people in the room and the air circulation is poor. If a person has cold symptoms, it will soon spread to others. Air conditioning causes serious lower respiratory diseases, especially pneumonia. Especially when working and studying under central air conditioning, central air conditioning is very suitable for the spread of Legionella, and the incubation period is about 2~ 12 days. Although the upper respiratory tract is unresponsive, it has fever, chills, muscle aches, dry cough, no phlegm or less phlegm. If not treated in time, it will continue to have fever, dry cough and chills. In addition, turning on the air conditioner for a long time will lead to such problems: too low humidity is not good for people's eyes and nasal mucosa, and people should be especially careful when their noses and throats are dry; Too "cold" can easily lead to the weakening of gastrointestinal movement, so it is not surprising that people often eat cold drinks, pull and vomit: low temperature can stimulate the sharp contraction of blood vessels and poor blood circulation, leading to joint injury, cold and pain. Try to avoid staying in an air-conditioned room for a long time. If possible, it is best to keep the room temperature around 24℃, and the temperature difference between indoor and outdoor exceeds 7℃. It is best to turn off the air conditioner for a period of time and open the window to breathe fresh air after turning on 1-3 hours. If conditions do not permit, it is best to go to outdoor corridors and other places with windows for air exchange every hour, especially during lunch break. The most important thing is not to blow directly under the air conditioner because of the heat. Always go in and out of the air-conditioned room, there must be a temperature transition, for example, turn up the temperature or turn off the air conditioner first, and be sure to dry the sweat when you enter the door. Stay in an air-conditioned room for a long time, drink as much water as possible, and often mop the floor with a mop filled with water to moisturize. If you have cold symptoms, you should go to the hospital in time to avoid deterioration and cross infection.
