Masks used improperly to prevent damage to health
Masks are not good for heat prevention and disease prevention
In the cold winter, the only role that many people wear when wearing masks is to warm up. In fact, the effectiveness of masks is not only poor, they will not achieve the effect of preventing diseases, and may also reduce the body's immunity. This is because people's nasal mucosa has a rich network of blood vessels and cavernous blood vessels, and the blood circulation is very active. It has a natural warming effect on the inhaled cold air, and the human nasal tube is very tortuous, which greatly increases the number of nasal mucosa. Area, so that the heating effect is further enhanced. In this way, when the human body inhales cold air into the lungs through the nasal canal, it is close to the human body temperature due to the warming effect. However, when a person wears a mask, the air exhaled from the body will become cold on the mask and become cold. On the one hand, it will make the face feel colder. On the other hand, the damp and relatively unsanitary environment is not conducive to the person's mouth and nose. The health of the site.
In addition, the body's ability to resist cold should also be improved through gradual exercise. If a mask is worn all day long, the nasal cavity and the entire respiratory tract are not exposed to cold air, they will not be able to exercise, and the immunity will gradually decline, and they will be more susceptible to catching a cold.
Wearing a mask still has some hidden dangers
Some people wear the same mask for several days in a row. Sometimes it is even more convenient for the user to turn the mask over to wear it. This is not good for human health. Because, after wearing a mask for a period of time, both inside and outside will become unhygienic, in which the outside will carry a lot of dust, bacteria and other pollutants in the outside air; the inside of the mask will be stained with the gas and saliva they exhale, etc. There will be some bacteria, viruses, etc. If you wear the same mask for a long time or turn it over, it will cause the mask to inhale the body, causing illness.
If it is necessary to wear masks, usually several more should be prepared, it is best to change every day; when cleaning masks, the mask should be put into the boiling water for a few minutes, cleaned and then get dried in the sun to dry, so that Play sterilization and disinfection.
