Introduction of face masks
The correct way to use a face mask:
First, wash your hands and open the package of the face mask, and judge the inner and outer layers of the face mask. Generally, the inner layer is the inner layer and the outer layer is outside the folded layer. Secondly, pick up the fece mask with both hands and spread it over the ears. Press the metal strip at the upper nose of the face mask with both hands to make the upper end of the mask close to the bridge of the nose. Pull the mask downwards so that the mask does not leave wrinkles, so as to maintain the tightness of the mask. Finally, after using the face mask, be sure to wash your hands when you take it off, and store the face mask in a cool, ventilated, and dry environment.
The benefits of wearing a face mask:
1. Prevent the spread of respiratory infectious diseases, including common cold, influenza, pneumonia, tuberculosis, etc. The main way of transmission of these diseases is through droplets. For example, when talking loudly, sneezing, coughing or spitting, some pathogens will run into the air and spread to other people through droplets. The current new type of coronavirus is a highly contagious pathogen. Of course, other viruses and bacteria should not be ignored. Wearing masks can play a good role in respiratory prevention and isolate the bacteria.
2. Prevent allergic diseases, including allergic rhinitis, allergic dermatitis, allergic asthma, etc. In our lives, we often come into contact with some allergens, such as pollen, dust, animal fur and so on. After these substances come into contact with the mucosa of the face and nasal cavity, it can cause hyperemia, congestion and swelling of the mucosa, and then symptoms such as nasal congestion, sneezing, runny nose, skin itching, etc., and even anaphylactic shock in severe cases. If we wear a face mask, we can effectively reduce our exposure to allergens, thereby preventing allergic diseases.
3. Anti-smog. There are many toxic substances in the haze that can cause great harm to the human body, and have an impact on the respiratory system, cardiovascular system, and nervous system. Wearing a mask correctly can effectively prevent pollutants from entering the respiratory tract and isolate toxic and harmful substances. Therefore, it is necessary to wear a face mask when going out in a haze day.
4. Prevent "second-hand smoke". We may encounter the harassment of “second-hand smoke” on some occasions, and wearing face masks can prevent “second-hand smoke” to a certain extent, especially good-quality activated carbon masks. This kind of mask can absorb and filter part of the smoke, nicotine, tar and other harmful substances, which can reduce the harm to the body to a certain extent.
