Do you "wear" masks in winter? The correct way to wear masks in winter

with the rapid development of society, the haze on the road is more and more serious now, and winter is the most important time of the year. Therefore, in winter, everyone generally has the habit of wearing masks when going out! There are three precautions about wearing masks in winter. Let's take a look. Are you right to wear masks in winter?

three precautions for wearing masks in winter: no need to wear professional protective masks

Look at the sky if you wear a mask or not

In real life, some people who are afraid of cold wear big masks all day, thinking that they can prevent cold. In fact, 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. This physiological function of the human body is enhanced through exercise, so as to improve the cold resistance. If you wear a mask, the nasal cavity and the entire respiratory tract mucosa can not be exercised, a little cold, it is easy to catch a cold. Therefore, it's bad for health to keep the mask on your mouth all day in winter.

However, winter is a high incidence period of haze. There are a lot of PM2.5 in haze, which is easy to enter the respiratory tract and stimulate the mucous membrane, even damage the lungs, and easily induce a variety of diseases including respiratory tract infection. At this time, the adverse effect of wearing a mask on human health is lighter than the harm of dirty particles in the air in haze weather.

No need to wear professional protective masks

At present, the state has not issued the standards for civil masks, and the quality of masks on the market is uneven. We must choose masks with large brands and regular product packaging and instructions, such as disposable surgical masks or masks with more than 12 layers of gauze. Don't be greedy for cheap. Buy masks at the stall without a health license.

It is not necessary to wear N95, n99 and other professional protective masks in order to filter PM2.5. Theoretically speaking, the more airtight the protective material of the mask, the better the effect of blocking particles. Conversely, the more airtight the 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.

There is no need to wear masks all day. Once the visibility is better, the haze disappears, or in the car, indoor and other clean air environment, the masks can be removed. 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 mask every day. When cleaning the mask, put the mask into boiling water for a few minutes, clean it and then get it to the sun for drying, 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 glasses at the same time, the trouble will come. The hot breath you exhale will surely penetrate between the lens and the eyes through the gap between the nose corner and the mask on both sides. 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 with better heat dissipation or 'antifogging lens'. It can also be purchased on the market. General antifogging agents have the functions of cleaning, decontamination, frost prevention, fog prevention and vision protection. They have no irritation to the skin, no corrosion to the mirror surface, and are easy to use. They can be used for 1-3 days without fog.

Of course, you can also make 'glasses anti fog water'. First put the fully soluble soap flake into 10ml warm water to make soap liquid, then pour 30ml glycerin, it's better to add a few drops of turpentine oil, and finally mix evenly. Even if 'glasses anti fog water' is made successfully. When using, only apply anti fog water on the lens, and then wipe with glasses cloth. The anti fog can last for 3-4 hours. This method is most suitable for those who often take outdoor activities in winter and wear glasses and masks at the same time, because the glasses can be used for half a day without worry.

Warm tip: in real life, many people will wear masks all day because they are afraid of the cold, which can prevent cold, but it is harmful to breathing. In normal life, you need to take full care of your body so as not to affect your life. In addition, you should pay attention to some matters when wearing masks, which are not professional masks to be effective Cold proof.
