Precautions for the use of masks

1. The wearing time should not be too long. 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 poor ventilation. Of course, when walking in the wild, masks can also resist wind, sand and cold, or when moving in an environment with air pollution, you need to wear masks, but the time should not be too long.
2. The outer layer of the mask often accumulates dust, bacteria and other substances harmful to the human body in the outside air, while the inner layer is responsible for blocking exhaled bacteria, saliva, etc., so the two sides cannot be used alternately, otherwise the outer layer will be contaminated. The object is directly close to the face, so as to be inhaled into the human body and become a source of infection.
3. Disinfection method of masks. Some washable masks can be washed and soaked in water containing toilet water for about 15 minutes, so that the sterilizing ingredients in toilet water, such as borneol, mint, cork, and medical alcohol, can remove the dust on the mask, bacteria, etc.
