1. Do not wear a mask for a long time
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 poor air circulation. Of course, walking in the wild, in order to resist wind, sand and cold, or activities in an environment with air pollution, it is necessary to wear a mask, but the time should not be too long. In addition, during the flu season, you should wear a mask when you go to public places where there may be a large number of pathogens. Wearing a mask is only one of the ways to prevent respiratory infectious diseases, and the most important thing is to maintain good living habits.
2. Cleaning and maintenance of masks
The outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt on the outer layer will be directly attached to it. It becomes a source of infection by inhaling the body when it is face. When you are not wearing the mask, you should fold it and put it in a clean envelope, fold the side close to your nose and mouth, and don't just stuff it in your pocket or hang it around your neck.
Third, the disinfection of masks
1. Cleaning. First rub the gauze mask gently with warm water and soap. The bowl-shaped mask can be gently cleaned with a soft brush dipped in detergent, and then rinsed with clean water. Please be careful not to rub it hard, because if the warp and weft gap of the gauze is too large, it will lose its anti-dropping effect.
2. Disinfection. Soak the cleaned mask in 2% peracetic acid solution for 30 minutes or boil it in boiling water for 20 minutes or steam it in a steamer for 15 minutes, and then dry it for later use. This method is suitable for gauze masks and bowl-shaped masks.
3. Check. Before using again, you should carefully check whether the masks and face shields are still intact. For gauze masks and face shields, you can take the light transmission method, that is, take a look in front of the lamp to see if there are obvious light spots. The middle part and the edge part are transparent. Is the rate consistent? If in doubt, replace it with a new one.
