Chemical Fiber Masks Will Aggravate Asthma And Cause Skin Allergy.

Influenced by snowfall and fog and haze, masks have become the essential products for many people to keep warm and dustproof. However, they are worn by people.

"Buying ordinary respirators should be tasteless and pure cotton. The ordinary gauze mask should be the first choice of ordinary citizens in daily life."

Yang Wenyu said that the low price printing and dyeing masks contain chemical fibers, and all kinds of cartoon designs are printed on the front, which affect the air permeability.

Masks should be chosen to cover most of the areas below the nose, mouth and orbit.

Experts advise not to spray perfume and other pungent substances on the respirator, because aromatic substances can stimulate the respiratory system and induce respiratory diseases.

Wearing a mask for a long time will make the nasal mucosa vulnerable. Yang Wenyu said that in order to avoid prolonged cold fresh air, resulting in a decrease in nasal mucosal resistance, masks should not be worn for more than six hours.

The outer layer of the mask often accumulates dust, bacteria and other pollutants in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, in view of the cleanliness of the mask, the experts point out that the two sides should be avoided alternately, so as to avoid inhaling the contaminants on the outer layer when they are directly attached to the face and become the source of infection.

Meanwhile, the masks worn should be cleaned daily and exposed to sunlight or irradiated with purple light.

In addition, some people believe that wearing ordinary masks can prevent germs. In fact, only medical masks can prevent bacteria from being inhaled, because medical masks are made of at least 12 layers of sterile gauze, and there are strict requirements for the size and disinfection of respirators.

Ordinary masks are not strictly sterilized themselves, and chemical fiber masks are more difficult to effectively filter viruses and dust in the air.

People wearing masks usually need to wash their masks every day, preferably in hot water, regularly replace masks, and be careful not to wear masks for a long time, otherwise the nasal mucosa will become fragile.
