    < p > fog and haze is a mixture of fog and haze. Haze can cause some harm to human health, especially the respiratory system and cardiovascular system. For patients with chronic respiratory diseases such as bronchial asthma, chronic bronchitis, obstructive pulmonary emphysema and chronic obstructive pulmonary disease, haze weather can cause acute or acute exacerbation of the disease. If you are in this environment for a long time, you will also induce lung cancer. Haze weather also has a serious impact on human cardiovascular and cerebrovascular diseases. It will hinder normal blood circulation and lead to cardiovascular disease, hypertension, coronary heart disease and cerebral hemorrhage, which may lead to angina pectoris, myocardial infarction, heart failure and so on. < /p >
    < p > because winter fog is called "winter killer", it is generally believed that fog and haze occur in cold winter and early spring. In fact, haze will also happen at high temperatures. For example, the highest temperature in Beijing is 30 degrees on the summer day. The Beijing Meteorological Observatory has issued a haze yellow warning signal. In fact, in addition to climate factors, pollutants such as industrial waste gas, automobile exhaust, dust in the air, bacteria and viruses in the air are also the "culprits" causing haze. < /p >
    < p >, how to resist the harm of haze to human health? Many people think of < a href= "http://fz.sjfzxm.com/" > mask "/a". You can't see, even at high temperatures above 30 C, there are people wearing masks. However, medical experts believe that wearing masks can prevent some dust from entering the nasal cavity and play a protective role. But for PM2.5, even professional medical masks are limited in their ability to resist. Because the professional mask is mainly targeted at more than PM3 of the absorbable particulate matter, the ability to resist human particles under PM2.5 is not strong. < /p >
    < p > PM2.5 refers to particulate matter whose diameter is less than or equal to 2.5 microns in diameter, also known as particulate matter. Its diameter is less than 1/20 of human hair. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with the coarser atmospheric particles, PM2.5 has a small particle size, rich in toxic and harmful substances, and has a long residence time and a long distance in the atmosphere. Therefore, it has a greater impact on human health and atmospheric environmental quality. < /p >
    < p > experts point out that if masks can block PM2.5, it must be very delicate. It will be difficult for people to breathe. Most of the respirators used by the public can not be sure that they are completely closed to the face. There is a little gap between them and PM2.5 can go in. So most of the masks on the market now do not achieve the effect of blocking PM2.5. As for the adsorption of activated carbon, it is even nonsense, because the main function of activated carbon is to separate the taste, and the filtration capacity of suspended particles is almost zero. < /p >
    < p > however, many businesses now have all kinds of respirators with fog and haze, PM2.5 and dust prevention functions. Products include imports, joint ventures, and domestic products. There are numerous varieties. The price ranges from several yuan to 100 yuan. < /p >
    < p > then, does the sales of the functional mask on the market really have the function of fog prevention and haze? The Chinese Consumers Association has conducted a comparative test on the protective performance of the 37 masks sold on the market. The results showed that only 9 anti haze effects were good and the comfort was less than 30%. At the same time, under the same testing standards, the mask haze prevention effect of more than 100 yuan is not necessarily better than the product within 10 yuan. < /p >
    Not long ago, "P", the Zhejiang Provincial Consumer Protection Commission made a comparative test on all kinds of masks sold on the major business websites such as a href= "http://fz.sjfzxm.com/" > Tmall < /a >, Jingdong, Amazon and No.1 store. 29 batches of respirators were sampled and 25 batches were detected (4 batches were not included in the test area for lack of any commodity information). No batch of masks had reached the national standard requirements, the lowest filtration effect was only 5%, and the highest was only 82.2%. < /p >
    In view of this, industry experts point out: do not blindly believe in the so-called functional mask, and do not believe in the mask bought by the shop, because some functional masks bought from the shop are not as reliable as the similar products in the small commodity market. P < /p >
    < p > most consumers say that in the face of such an intricate market, how to choose the appropriate respirator is really difficult, and most of the time it is only recommended by businesses. However, the consumers have such a "trick" for consumers: there are many kinds of masks, such as professional a href= "http://fz.sjfzxm.com/", dust mask, /a, medical mask, thermal respirator, and so on. Different masks are divided into different types. Therefore, when buying masks, consumers should buy different masks in regular channels according to specific circumstances. At present, the mask with better anti fog and haze effect is a disposable cup mask and a disposable folding mask made of non-woven material with filtering effect. Note that these two kinds of masks are not washable and can not be reused. They should be discarded when they feel bad smell or breathe suffocation and replace the new respirators. At the same time, when choosing masks, do not only pay attention to the types of masks, but pay attention to the appropriate wear. Choose the mask that can be tightly attached to the face and choose the mask that matches their nose and face. Otherwise, there will be gaps and the dirty air will not be protected. < /p >
    < p > for the respiratory system, cardiovascular disease patients and the elderly and children, we should avoid the harm caused by haze and not regard the mask as a magic weapon. The best way is to reduce outdoors and close doors and windows at home. When going out, you should wash the face and naked skin immediately. Conditioned families can install air purifiers, but be careful when you use them. < /p >
    < p > many elderly people have the habit of exercising in the morning. It is best not to take outdoor exercise. Sports can speed up blood circulation, and it is easier for people to absorb germs in fog. From 6 to 11 in the morning, the time of pollution is more serious. The air at night is relatively clean. < /p >
