From the point of view of human physiology, blood circulation in the nasal mucosa is very strong, the channels in the nasal cavity are very tortuous, and the nasal hairs constitute a filtering "barrier". When air is sucked into the nostrils, the airflow forms a vortex in the tortuous channel, which heats the airflow sucked into the nasal cavity. Some tests have shown that when cold air at minus 7掳C is drawn into the lungs through the nasal cavity, the airflow has been heated to 28.8掳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 the original physiological function of the nasal cavity will be lost, 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 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 there may be a large number of pathogens, you should also wear a mask. Wearing a mask is just one of the ways to prevent respiratory infectious diseases. The most important thing is to maintain good living habits.Buy Disposable Protective Face Masks
