Precautions for children's masks
Some tests have shown that when cold air at minus 7 ° C is drawn into the lungs through the nasal cavity, the airflow has been heated to 28.8 ° C, which is very close to the temperature of the human body.
If you wear a mask for a long time, the nasal mucosa will become fragile and lose the original physiological function of the nasal cavity, so you cannot wear a mask for a long time. Masks can only be worn in special environments, such as places with many people and no air circulation.
Of course, it is necessary to wear a mask to walk in the wild to resist the wind and sand, or to move in an environment with air pollution, but the time should not be too long.
In addition, in the flu season, go to public places where a large number of pathogens may exist, you should also wear a mask. Wearing a mask is only one of the ways to prevent respiratory infectious diseases. The most important thing is to maintain good living habits.
