It's cold in winter. It's inevitable to wear masks when going out. But do you know how to choose masks in winter? Not everyone is suitable for wearing masks. What are the precautions for wearing masks? Let's take a look at the common problems of wearing masks in winter.
1. Weather decides whether to wear masks
In winter, when the temperature drops, some people who are afraid of cold wear masks all day to keep warm. In fact, wearing masks like this is not scientific. The surface of human respiratory tract, such as nose, throat and trachea, is covered with many mucous membranes, and there are microvessels under the mucous membranes. When the nose inhales cold air, through the crooked pipes into the lungs, it is close to body temperature. Wearing masks for a long time will weaken people's cold resistance and make them more likely to catch cold. Winter is a high incidence period of haze weather. When you go out in haze weather, you must wear a mask.
2. There is no need to wear professional protective masks
On the one hand, there is a large demand for masks in the market. On the other hand, the quality of masks in the market is uneven. Therefore, when choosing to buy masks, we must choose the masks produced by regular manufacturers. Do not buy masks at the stall without a health license. The professional protective mask is not necessarily suitable for all people, and it is not necessary to wear the mask all day long. As long as it is in a relatively clean environment, the mask can be removed. Disposable masks must not be used repeatedly, and non disposable masks must be cleaned and disinfected to achieve better bactericidal effect.
3. Remove the fog on the lens when wearing glasses
For those who are short-sighted and like to wear glasses, wearing a mask in winter is a very troublesome thing, because the hot breath when wearing the mask will make the lens blurred by the fog, and try to use anti fog lenses when wearing glasses. For those who often take part in outdoor activities in winter and wear glasses and masks at the same time, they must pay attention to their own safety.
