When cold air is sucked in by the nose, it passes through the tortuous duct and enters the lungs, it is close to body temperature. This physiological function of the human body can be enhanced through exercise, thereby improving cold tolerance. If you wear a mask all day and the mucous membranes of the nasal cavity and the entire respiratory tract are not exercised, you will be more likely to catch a cold if you catch a cold.

This can prevent respiratory diseases such as colds and coughs.
