Three precautions for wearing masks in winter
In daily life, because winter is cold, people often choose masks, which can avoid wind and cold, and is also conducive to regulating their respiratory system, avoiding haze and causing decreased respiratory function. You need to understand the choice of masks as soon as possible. What are the precautions for wearing masks in winter? Everyone should pay attention to a comprehensive understanding.
Three precautions for wearing masks in winter: There is no need to wear professional protective masks
Whether to wear masks or not, please look at the sky and see the weather ”
In real life, some people who are afraid of the cold wear large masks all day long and think that they can protect against cold. In fact, this is not scientific. The human respiratory tract, such as the nasal cavity, throat, and trachea, are covered with many mucosa, and there are microvascular vessels under the mucosa. When the nose sucks cold air and enters the lungs through the curved pipes, it is close to body temperature. This physiological function of the human body is enhanced through exercise, thereby improving cold resistance. If you wear a mask, the mucosa of the nasal cavity and the entire respiratory tract will not be exercised, and you will easily catch a cold when you get a little cold. Therefore, "masks are not left on your mouth" all day in winter, which is not good for your health.
However, winter is a high incidence of smog weather. The haze contains a large amount of PM2.5, which can easily enter the human respiratory tract and stimulate the mucosa, and even damage the lungs, making it very easy to induce a variety of diseases including respiratory tract infections. At this time, the adverse effects of wearing a mask on human health are relatively lighter than the harm of dirty particles in the air in haze weather to the human body.
No need to wear professional protective masks
At present, the country has not issued standards for civilian masks. The quality of masks on the market is of varying quality. You must choose masks with large brands, regular product packaging and instructions, such as disposable medical surgical masks or gauze masks above 12 layers. Don’t be greedy for cheapness and buy masks on street stalls without a sanitary license.
There is no need to choose to wear professional protective masks such as N95 and N99 in order to filter PM2.5. Theoretically speaking, the more airtight the protective material of the mask is, the better the effect of blocking particulate matter. Conversely, the more closed the mask is, the more obvious the respiratory resistance increases, and the more difficult it is to breathe. Wearing professional protective masks such as N95 and N99 requires training, otherwise it is easy to cause breathing difficulties and dizziness due to lack of oxygen.
There is no need to wear masks all the time. Once the visibility improves, the smog weather disappears, or in a cleaner environment such as cars and indoors, you can take off the masks. In addition, when using masks, avoid using both sides alternately and should be replaced at least once a day; the masks you have worn should be cleaned and disinfected every day. When cleaning the masks, you should first put the masks in boiling water and scald for a few minutes, clean them clean and then dry them in the sun, so that they can be sterilized and disinfected.
People wearing glasses should pay attention to removing the fog on the lenses
In winter, if you wear a mask and glasses at the same time, then the trouble will come: —— The hot air you exhales will definitely penetrate through the gap between the nose corners of both sides and the mask, and penetrate between the lenses and eyes. After a little longer, the fog will be blurred by the lenses, which will greatly affect the safety of people's vision and activities. There are still ways to remove fog from the lens. It is best to choose resin lenses with better heat dissipation or &ldquo "anti-fog lenses" &rdquo." You can also buy &ldquoise anti-fog agent on the market. Generally, anti-fog agents have the effects of cleaning, decontamination, anti-frost, anti-fog, and vision protection. They are not irritating to the skin, corrosion to the mirror, and are easy to use. They can keep fog for 1-3 days without fog.
Of course, you can also make your own “ "Glasses Anti-fog Water ” first put the completely dissolved soap slices into 10 ml of warm water to make soap liquid, then pour in 30 ml of glycerin, it is best to drip a few drops of turpentine oil, and finally stir evenly, "Glasses Anti-fog Water ” even if the production is successful. When using it, just apply anti-fog water on the lens and wipe it with a glasses cloth. The anti-fog can last for 3-4 hours. This method is most suitable for those who often move outdoors in winter and wear glasses and masks at the same time, because once using anti-fog, glasses and lenses can be worry-free for a long time.
Warm reminder, in real life, many people wear masks all day because they are afraid of the cold, so they can prevent cold, but they are harmful and are not conducive to breathing. In daily life, everyone needs to take comprehensive care of their bodies to avoid affecting their lives. Some things should be paid attention to when wearing masks. It is not a professional mask to effectively prevent cold.
