What should I pay attention to when wearing face mask in winter?

As we all know, haze is a period of high incidence in winter. There is a large amount of PM2.5 in haze, which is easy to be inhaled into people's respiratory tract and stimulate the mucous membrane. At the same time, it will damage the lungs, and it is easy to have many diseases of respiratory tract infection. After wearing Face Mask, it can well prevent the harm of dust in the air to human body. So in daily life, when people wear masks, they often have some mistakes, or ignore some details. What should we pay attention to when wearing masks? Here is a brief introduction.

No need to wear professional protective face mask. At present, there is no civil face mask standard in China, and the quality of face mask in the market is mixed. We must choose masks with big brands and regular product packaging and instructions, such as disposable Medical Mask. Don't be greedy for cheap. Buy a face mask at a stall without a health license.

It is not necessary to wear professional protective face masks such as N95 and n99 in order to filter PM2.5. Theoretically, the more airtight the face mask's protective material is, the better the effect of blocking particles is. Conversely, the more airtight the face mask is, the more obvious the respiratory resistance increases, and the harder it takes to breathe. Wearing N95, n99 and Other professional protective masks is to be trained, otherwise it is easy to cause breathing difficulties and dizziness due to lack of oxygen.

It's not necessary to wear a face mask all day. Once the visibility gets better, the haze disappears, or in the car, indoor and other clean air environment, you can remove the face mask. In addition, when using the mask, avoid alternating use of both sides, and replace it at least once a day; clean and disinfect the worn face mask every day. When cleaning the mask, put the mask in boiling water for a few minutes, clean it and then dry it in the sun, so as to play the role of sterilization and disinfection.

The wearer should pay attention to clear the fog on the lens

In winter, if you wear a mask and a face mask at the same time, the trouble will come - the hot breath you exhale will surely pass through the gap between the nose corners and the regenerator mask on both sides, and then it will penetrate between the lens and the eyes. For a little longer time, the lens will be blurred by the fog, which greatly affects the safety of people's vision and activities.

There are still ways to clear the fog on the lens. It is better to choose resin lens or "antifogging lens" with better heat dissipation. You can also buy "anti fogging agent for glasses" on the market. General anti fogging agents have the functions of "cleaning, decontamination, anti frost, anti fogging, and protecting vision". They have no stimulation to the skin, no corrosion to the mirror surface, and are easy to use. They can be used for 1-3 days without fogging at a time.
