There will be foggy days in Shanghai for nearly a month. How can we prevent it?

In view of how to realize self-protection and health care in haze weather, doctors put forward the following precautions:

First, try to reduce going out. Try to wear a mask when going out. Commonly used masks are generally made by folding several layers of absorbent cotton gauze. In order not to be too bored after wearing the mask, it is generally appropriate to choose 6-8 layers.

Second, do personal hygiene well. Fog seems mild, but it contains various harmful substances such as acid, alkali, salt, amine, phenol, dust and pathogenic microorganisms. Therefore, you should wash your face and expose your skin immediately when you go out in foggy days.

Third, exercise to avoid dense fog. Exercise itself will increase the amount of breathing, leading to inhalation of more harmful substances. People who have the habit of doing morning exercises should change outdoor exercise into indoor exercise. Generally, there is plenty of sunshine at noon, so they can go out properly. Old people should also keep scientific life rules and avoid overwork.

Fourth, adjust diet and improve immunity. Drink plenty of water at ordinary times, pay attention to a light diet, eat less irritating food, eat more foods such as tofu and milk, or eat more yellow croaker (and other marine fish), animal liver, egg yolk, lean meat, cheese and nuts. These foods are rich in vitamin D, which is very beneficial to calcium supplementation.

Fifth, because smog weather has the greatest impact on the respiratory system, it is most likely to cause acute upper respiratory tract infections, pneumonia and other diseases. You should eat more foods that moisten your lungs, such as Sydney, oranges, lilies, lotus roots and Siraitia grosvenorii.

Sixth, drink more tung platycodon grandiflorum tea, tung ginseng tea, tung platycodon grandiflorum granules and tung orange stem soup.

These herbal teas can prevent and treat throat itching caused by inhaling dirty air in foggy days, and have a good lung moistening effect. Moreover, it is known as the nemesis of PM2.5, especially in the afternoon, and the effect is better. Because the fog is thickest in the morning and almost disappears at noon, people inhale more dust and impurities in the morning, so they can clear their lungs in time when drinking in the afternoon.
