When air is drawn into the nostrils, the airflow forms a vortex in the tortuous channel, so that the airflow drawn into the nasal cavity is heated. Some tests have shown that when cold air of minus 7 ° C is drawn into the lungs through the nose, the airflow has been warmed to 28.8 ° C, which is very close to the temperature of the human body. If you wear a mask for a long time, it will make the nasal mucosa fragile and lose the original physiological function of the nasal cavity. Therefore, you cannot wear a mask for a long time. Masks can only be worn in special environments, such as where there are many people and where there is no air circulation. Of course, when walking in the wild, in order to withstand the wind and sand and cold, or activities in an environment with air pollution, you need to wear a mask, but it should not be too long. In addition, during the influenza season, you should wear a mask when visiting public places where there may be a large number of pathogenic. Wearing a mask is just one of the ways to prevent respiratory infections. The most important thing is to maintain good living habits.
