Everyone recommends a thickened mask for me to wear in winter, which has the function of keeping war

Using Hui's mask handle, it not only keeps warm and thickened, but also prevents haze and dust.

The nasal mucosa is rich in blood vessels and cavernous blood vessels, and the blood circulation is very vigorous, and when cold air is inhaled into the lungs through the nasal cavity, it is generally close to body temperature. The body's ability to withstand cold should be enhanced through exercise, and if you rely on wearing a mask to prevent cold, it will make the human body squeamish and more likely to catch a cold.

Winter begins at the beginning of winter, passes through light snow and heavy snow, and the winter solstice reaches the day before the beginning of spring. "Winter, heaven and earth are closed, water and ice are shut. "From the perspective of the growth law of all things in nature, winter is the season when everything is closed, and the natural world is yin and yang are declining, and everything has hidden yang energy to wait for the coming spring.

The winter wind is northerly, and its nature is cold. "Cold"It is the main feature of climate change in winter. Therefore, winter health care is even more important.

In winter, there are many unhealthy lifestyle habits that are often mistaken for correctness by some people. 

Wear a mask to protect against the cold. The nasal mucosa is rich in blood vessels and cavernous blood vessels, and the blood circulation is very vigorous, and when cold air is inhaled into the lungs through the nasal cavity, it is generally close to body temperature. The body's ability to withstand cold should be enhanced through exercise, and if you rely on wearing a mask to prevent cold, it will make the human body squeamish and more likely to catch a cold.

Sleep with your head covered. Putting your head under the covers will make you feel warmer, but the oxygen in the covers will become less and less, and carbon dioxide and unclean gases will accumulate more and more, so people who sleep with their heads covered will feel drowsy and tired when they wake up.

Wash your face with hot water. In winter, the sweat glands and capillaries of the human face are constricted under the cold air**. When hot water is present, it expands rapidly, but when the heat is dissipated, it returns to its low-temperature state. The capillaries shrink in such a way that it is easy to cause wrinkles on the face.

Drink alcohol to keep out the cold. The feeling of heat all over the body after drinking alcohol is the result of alcohol causing the body to emit its original heat energy. After drinking, a large amount of heat is dissipated from the body, which makes people have goosebumps all over their bodies, resulting in chills after drinking. 

Hands and feet are frozen and grilled over a fire. In winter, the hands and feet are exposed for a long time, and the blood vessels constrict and blood flow decreases. At this time, if it is immediately baked with fire, the blood vessels will be paralyzed and lose their contractility, and arterial blood stasis will occur, telangiectasia permeability will be enhanced, and local blood stasis will occur.

Mild ones form chilblains, and severe ones cause tissue necrosis. Therefore, the frozen hands and feet can only be gently rubbed to slowly return to the normal temperature.

** Itchy scratching with your hands. In winter, when you feel itchy due to dryness, you must not scratch it with your hands, otherwise it is easy to scratch** and cause secondary infection.

The prevention and control method is to drink more water, eat more fresh vegetables and fruits, eat less sour and spicy foods, and drink less strong alcohol. Bathe and change your underwear frequently. If the itching is severe, you can take drugs such as chlorphenirafinagen, or you can apply some calamine lotion or apply skin liniment ointment**.

Many people don't wear masks, so it's best to wear them.

It's bad to wear a mask to sleep

1: Wearing a DU mask to sleep and breathing unevenly

Evenly, I feel that the breathing is very undao

Comfortable, serious can make people stop breathing, although it is cold in winter, you can add a little more quilt, wearing a mask to sleep is not a wise choice.

2: Wearing a mask is easy to catch a cold, because there are abundant capillaries in the nasal mucosa, which have a heating and humidifying effect on the air entering the nasal cavity. If you wear a mask while sleeping, it is easy for the mucous membranes of the nasal cavity and the entire respiratory tract to not be exercised, resulting in a decline in function, easy to be infected by bacteria, and easy to catch a cold.

3: Wear a mask to sleep and multiply bacteria, after the mask is used for a period of time, it will attach a large number of bacteria, viruses and various particles in the atmosphere, coupled with the hot and humid air flow exhaled by people, bacteria and viruses will accelerate the reproduction and are more likely to harm health. Sleeping for a long time and wearing a mask can multiply bacteria and affect health.

Not good....If you have a cold face, the hot breath exhaled by wearing a mask can cause chilblains on your face...This is the same as roasting the fire immediately with cold hands, and you will get chilblains! However, it is still necessary to wear it in public places such as hospitals.

In winter, due to the lack of air mobility, it is easy to produce serious haze pollution. So wear a mask in winter, and the version can be pre-primed.

the right to prevent air pollution; second, it can keep warm; Thirdly, if you wear activated charcoal, you can also prevent minor toxic gas and ozone pollution. According to the test of Lanhe mask laboratory, more than 90% of cotton masks on the market contain carcinogenic fluorescent agents, even the big-brand 3M Naishikang is not immune, and it is recommended to use professional-based Lanhe cotton masks and Lanhe disposable masks and other series of masks.

Prevent inhalation and there is a windproof dry lips

Wear a mask, smog, allergic rhinitis, respiratory diseases, flu, cough, tuberculosis, infectious diseases, health.

If it is dust-proof, it is recommended to wear a silicone dust mask to prevent allergies and dermatitis caused by sweat and secreted oil from reacting with the main body of the mask.

The way to clean dust: Now dust masks must implement the GB2626-2006 standard. Dust masks are divided into three grades: KN100, KN95 and KN90.

Among them, KN100 can achieve nearly 100% (more) protection effect against ultrafine dust. If the granularity is large, KN95 grade can be selected. The effectiveness of protection depends on 2 aspects.

One is the filtration efficiency of the filter cotton. The second is the air leakage rate after the mask is mated to the face.

Therefore, masks must be divided into large and small sizes, and the air leakage rate between masks and faces varies from person to person.

The way to clean dust: the scientific selection of dust masks certified by GB2626-2006 standards can help prevent lung damage.

1. Choose a duplex half mask type. Disposable masks are not suitable for long-term or occupational protection due to their high air leakage rate.

2. Select KN100 level. A high dust environment with a low protection rate will lead to physical injury.

3. Choose a silicone mask, which has a relatively long service life, soft and comfortable. Wear it for a long time and it is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation.

4. Masks are divided into large and small sizes, which is extremely important. It is not recommended to buy those so-called universal models of masks, which are prone to air leakage.

5. There are two types of masks covering the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable.

6. It is recommended to choose a breathing mask. Some masks are designed with double filter cotton + double filter surface, which is relatively smooth to breathe and has a long service life. In particular, the breathing resistance, the transparent mask is effective in relieving the stuffiness caused by the weather.

It is recommended to evaluate occupational protection from the above quality, grade, comfort and economy, and choose a good mask that can effectively prevent pneumoconiosis.

There is no doubt that of course cotton is good!

I've bought a lot of anti-smog masks before, but sometimes I really don't want to wear them, it's too ugly, and it's uncomfortable to wear. Some time ago, I went to New Zealand to play, and I saw a mask that would heat up in the pharmacy, and the protective effect was also good, and the appearance was very high, so I bought several boxes in one go.

Generally, masks are fine, and those sold by pharmaceutical companies or online say that they can be prevented, which is pseudoscience, and they are all looking for selling points
