Yanjiao 8 17 930 can I go in foggy weather?

Outdoor activities with a certain intensity are generally not recommended in foggy days, because there are a lot of dust or PM2.5 particles in fog in China, that is, smog, which is easy to inhale particles during a lot of exercise, while fine particles with a particle size less than 2.5 microns are equivalent to the size of110 of human hair and are not easy to be blocked. Inhalation into the human body will directly enter the bronchus, interfere with the gas exchange in the lungs, and cause diseases including asthma, bronchitis and cardiovascular diseases. Moreover, once PM2.5 enters human internal organs, it is basically impossible to be excreted, which means that the injury is permanent, so for safety reasons, it is recommended not to go out for a walk or run in foggy days.
