Tell you how to choose a mask

On November 1st, China's first national standard for protective face masks - the "Technical Specification for Daily Protective Masks" (hereinafter referred to as "the Code") will be formally implemented. The standard will protect the fine particles (PM2.5) and wear it. Safety performance has been clearly defined.

According to the standard, the protection level of the mask is divided into four levels from low to high: D level, C level, B level, and A level, which correspond to different air quality conditions. For example, class A corresponds to "severe pollution" and is used when the concentration of PM2.5 reaches 500 micrograms per cubic meter; class D corresponds to "moderate or less pollution" and applies to situations where the concentration of PM2.5 is less than or equal to 150 micrograms per cubic meter. .

How to choose a mask? Filter layer is the key

With daily protective mask-related regulations, many people want to know how to choose a mask. Every person should wear a mask with appropriate protective effect according to the weather and their own situation, and do a proper protection.

In addition to specialized anti-fog masks, there are cotton masks and disposable medical masks on the market. Pure cotton cloth and gauze masks have little effect on the filtering of PM2.5. It is the filter layer formed by the non-woven cloth or other corresponding filter material in the mask that can really play the role of filtration. Now there are special anti-fog and smog masks on the market, and some breathing masks are also installed on the masks. Breathing valves have a certain effect on relieving respiratory resistance. Of course, whether or not there is a breathing valve on the mask, as long as it complies with the "Code", it is all right.

What is good for preventing smog?

Although food cannot completely remove haze hazards, a scientific diet can mitigate the negative consequences of smog. The following are recommended beneficial foods:

Rich in antioxidants

Various polyphenols and carotenoids in fruits and vegetables have antioxidant effects and can reduce the degree of oxidative stress in the body. If you eat less fruits and vegetables, try eating a pound of vegetables and half a catty of fruit every day. Try to pick more dense varieties, strong antioxidant, such as strawberries, mulberry and other anthocyanin-rich purple fruit, the effect is stronger than peaches, pears, yellow peach than white peach, purple sweet potato than sweet potato.

Rich in Omega-3 fatty acids

Omega-3 fatty acids have the effect of reducing inflammation. For those who are not anaemic, the proportion of fish and meat can be adjusted appropriately, red meat (especially beef and mutton) that increase inflammation can be reduced, and smoked barbecued meat can be reduced (higher oxidation and carcinogens). ), increase the proportion of fish fisheries.

Rich in carotene and chlorophyll

Carrots, pumpkins, mangoes, papayas and other fruits and vegetables are rich in carotene, and spinach, leeks, canola, kale and other dark green leafy vegetables are rich in chlorophyll and carotene. Among them, chlorophyll helps to reduce the mutagenic effects of certain chemical poisons, while carotene favors the resistance and repair ability of epithelial tissues (including the digestive tract, respiratory tract, reproductive tract, mucous membranes of the eye, and skin, etc.). If vitamin A is lacking, the body's respiratory mucosa resistance decreases. According to the recommendations of our dietary guidelines, we should eat about half a catty of green leafy vegetables every day. Carrots should also be eaten regularly.

Rich in vitamins

Vitamin B, vitamin B, folic acid, vitamin C and vitamin E and other nutrients can weaken the health damage caused by atmospheric pollution. For example, asthma children suffering from atmospheric pollution will have decreased ventilation after increasing VC and VE intake. Lighter.

Bad days must go out, it is best to wear a hat

As the fog goes out, anti-snoring masks are indispensable. In fact, not only does inhalation of smears from the nose and mouth impair human health, but exposure of the head to the fog will increase hair loss. As a result, hazy days go out and hats should become essential items.

A study at the University of London, UK, showed that researchers collected bald head hair follicles from men. They found in the laboratory that the chemical poisonous substances in the air mixed with scalp oils and oxigenates could cause clogged pores and damage to the hair, directly affecting hair health and easily inducing hair loss. The strong adsorption of hair itself, exposed to the air in the hazy days, will attach a lot of pollutants.

When the fog is out of the sky, besides the hair and the nose and mouth, other parts of the body are exposed as little as possible. It is best to wear a scarf or a long coat.
