Prevention and control of haze weather

You can wear a mask when you go out, which can effectively prevent dust particles from entering the body. Cotton masks are the best because some people are allergic to non-woven fabrics, while cotton masks are generally not allergic and easy to clean. In addition, if you choose a suitable mask, ordinary masks have little effect on 2.5 micron airborne particles. To block PM2.5, a medical N95 mask is needed, which can block 95% of 0.3 micron particles and also play a certain role in PM2.5 weather off the charts. To buy a formal and qualified N95 mask that matches your face size, you should wait until it is dry and fold it in half to prevent the breathing moisture from breeding bacteria on the mask. It should not be worn for too long, and the elderly and patients with cardiovascular diseases should avoid wearing it to avoid dizziness caused by dyspnea.

2. Avoid doing morning exercises in foggy weather.

The amount of oxygen needed by the human body increases during morning exercise. With the deepening of breathing, harmful substances in the fog will be inhaled into the respiratory tract, thus endangering health. You can do morning exercises after the sun comes out. You can also switch to indoor sports. Judging from the time when the sun comes out, the better time for outdoor sports in winter is 9 am.

3. Open the window less in foggy days

Experts say that in foggy weather, try not to open the window. If you really need to open the window for ventilation, you should try to avoid the morning and evening smog peak hours, and open the window for ventilation for half an hour to one hour at a time. At the same time, residents who use air conditioning for heating should pay attention to opening windows to ensure adequate indoor oxygen. You can plant a variety of green plants on your balcony, terrace and indoors, such as green crown-leaf plants such as green radish, evergreen and tiger orchid, because of their large leaves and strong adsorption capacity. You can also use an air purifier. 80% of air purifiers in the market mainly purify fine particles in the air, which has a good adsorption effect on PM2.5, but you should pay attention to changing the filter element frequently when using it.

How to prevent smog weather: Eat a light diet and eat more vegetables.

4. Eat a light diet and eat more vegetables

The diet in haze weather should choose foods that are easy to digest and rich in vitamins, and eat more fresh vegetables and fruits, which can not only supplement various vitamins and inorganic salts, but also play the role of moistening lung, resolving phlegm, relieving cough, strengthening spleen and tonifying kidney. Eat less irritating foods and eat more foods that nourish yin and moisten the lungs, such as pears, oranges, lilies, black fungus and pig blood.

5. Drink more arhat fruit tea

Arhat fruit tea can prevent and treat throat itching caused by inhaling dirty air in foggy days, and has a good lung moistening effect. Especially in the afternoon, 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.

6. Clean skin

The skin on the surface of human body is in direct contact with the outside air, which is very vulnerable to smog weather. Going out for a long time is easy to form blackheads in the pores of the skin, causing skin problems such as pore blockage, keratin accumulation and skin peeling. Therefore, the primary measure of self-protection is to deeply clean the skin surface and clean pores.
