Constellation suitable for wearing masks in winter

In winter, people always wear masks to keep out the cold, but wearing masks often is not good for their health, because masks themselves have many safety and health risks. If used improperly, they can not only keep warm and protect health, but also bring some diseases to human body.

The first is health risks, which will reduce people's immunity. Because in the cold winter, people wear masks only to resist the dust and smog in the air, but this will reduce their immunity, because there is a layer of mucosa in the nose that can block the dust in the air, and there are very rich blood vessels, and the blood circulation speed is also very fast. Cold air is inhaled into the human body and heated in the nasal cavity at first. The pipeline of the nasal cavity is very tortuous, not straight up and down.

So when the cold air reaches the lungs, it has all been converted into heat, but if you keep wearing a mask, there will be problems. The mask will cause the lower part of your face to exhale by itself. If you suddenly take off the mask, cold air will suddenly invade the nasal cavity, which will easily slow down the blood circulation and lead to dry cough. Be sure to pay attention.

Then there are health risks. Some people always wear the same mask in winter for convenience. In fact, this is very unhealthy, because the mask is covered with dust, and there are some gases and saliva exhaled by our mouths. If you wear it every day, it will also smell, which will not only cause respiratory diseases, but also cause respiratory diseases. If you must wear it, buy more or clean it every few days, so it can be cleaner.
