How about doing morning exercises in foggy weather?

It is not good to do morning exercises in foggy weather. ?

In the case of continuous smog weather, people should appropriately reduce outdoor sports, especially morning exercises and mountain climbing. When the fog is heavy in the morning, harmful gases in the air will easily form small particles when encountering water vapor, which will pile up and sink together, resulting in suspended particles floating lower in the fog. During exercise, these inhalable particles are more likely to enter the respiratory tract, stimulate mucous membranes, and even damage the lungs, leading to respiratory diseases. For the elderly who already suffer from respiratory diseases such as asthma and chronic bronchitis, they are more likely to have discomfort symptoms such as shortness of breath, chest tightness and wheezing.
