Is it harmful to your health to go out and play badminton in the open air at twelve o'clock every morning in winter?

The answer is yes. Playing badminton must be hot and easy to sweat. However, it is cold in the middle of the night. If you don't put on clothes in time after sweating, it will easily lead to cold invasion, ranging from a cold to a cold, leading to cold invasion of joints and rheumatism.

In addition, night is actually the time when the air is the most unclean, especially outdoors. The dust flying around all day is in the air, and long-term exercise at night will also have an impact on the respiratory tract.
