Is it useful to wear a mask? Remember to choose a mask at four to take effect

Nowadays, haze weather is “prevalent”, especially in big cities. Since the beginning of winter, many office workers have bought a thicker cotton mask, which they wear every day to and from work to prevent cold wind from blowing their noses and soothing the nasal cavity. However, the small mask blocked the cold and could not stop the "cold" of rhinitis.

Case: Things will start from ten days ago. "Itchy nose and stuffy nose, uncomfortable, I don't know where to catch it now." A female white-collar worker used to have allergic rhinitis only in the spring, but she could use some medicine to control her symptoms. God will do the same. The son stained her mask the night before. As a result, the lady did not use a mask early in the morning yesterday, and went directly out of the silk scarf. Unexpectedly, it was more useful than a mask. "I feel the symptoms are obviously not that serious. Is there something wrong with the mask?" The lady was surprised.

Cotton masks are not suitable for cotton allergies

It turns out that the rhinitis of the lady is a typical allergic rhinitis, and she is more sensitive to cotton wool.

Ladies go out when the temperature is relatively low, and cold air irritation causes rhinitis attacks, which is more common. "But the lady chose to wear cotton masks in order to prevent breathing more cold air, and her allergy to cotton wool aggravated the symptoms of rhinitis."

In clinical practice, many patients are in the early stage of treatment, and do not insist on treatment if they feel that their symptoms have improved. This way, without standard treatment, rhinitis can easily be ambush all year round. When external conditions change, it is easy to induce rhinitis.

Choose to wear learned masks

1. When choosing a mask, you should first consider whether it meets sanitary standards. Gauze masks are better, other fabrics are not breathable, too thin does not work, too thick and affects breathing. There are differences in the number of layers of gauze masks. Masks with too few layers do not provide protection. It is best to choose 9 to 12 layers.

2. When buying a mask, you must pay attention to whether there is a product registration certificate number on the product packaging bag. Some regular manufacturers will also indicate the product implementation standards, production license numbers and other information on the packaging bag. Although the ordinary medical masks are simple in style, they are cheap and meet hygienic standards. They also have a certain warming function and can be used with confidence.

3. Wash your hands before wearing the mask and before and after taking it off. The mask should completely cover your nose, nose and chin. If it is damaged or soiled, it should be replaced immediately.

4. Masks should not be worn for more than 6 hours. They should be changed and washed once a day. They should be scalded with boiling water for 5 minutes before being washed with soap.
