What preventive measures can be taken in foggy days?

First, reduce going out. The elderly and children with weak resistance and people susceptible to respiratory diseases should try to reduce going out or outdoor activities. When they go out, they must wear masks to prevent pollutants from invading their lungs through their mouths and noses. After returning from going out, you should immediately wash your face and expose your skin.

Second, reduce outdoor sports. Haze weather has low air pressure and low visibility, and a large number of toxic particles such as dust are suspended in the air. Patients with chronic respiratory diseases such as bronchial asthma and chronic bronchitis should avoid outdoor exercise as much as possible, so as not to induce the onset or aggravation of chronic diseases.

Third, close the doors and windows. Because the pollutants in the air are difficult to dissipate in foggy days, doors and windows should be closed in foggy days to avoid outdoor fog entering the room to pollute the indoor air and induce acute respiratory and cardiovascular diseases. Choose public transportation to travel. You can choose to travel by bus and subway to reduce the number of cars.

Exhaust emissions, reduce smog, everyone is blue.

Fourth, smoke less. Cigars, cigars and pipes will produce a large number of fine particles belonging to the category of PM2.5 if they are not completely burned. Tobacco smoke contains more than 7000 compounds, including 69 carcinogens and 172 harmful substances, which will seriously harm the health of smokers themselves and those who inhale "second-hand smoke", especially in this smog weather. Therefore, smokers should try to smoke as little as possible whether they go out or stay indoors in recent days.

Fifth, do a good job in personal hygiene. Wash your face, rinse your mouth and clean your nasal cavity in time after going out to prevent the harm of PM2.5 to human body. It is best to use warm water when washing your face, which is beneficial to wash off the particles on your face. When cleaning the nasal cavity, you can repeatedly clean it with a clean cotton swab dipped in water, or repeatedly absorb water with your nose to blow your nose quickly and avoid choking. In addition to face cleaning, bare parts of the body should also be cleaned. Sixth, the diet is light. Eat less irritating food and more fresh vegetables and fruits, which can supplement various vitamins and inorganic salts, moisten the lungs and remove dryness, eliminate phlegm and relieve cough, and strengthen the spleen and kidney. You can also eat more tofu, milk and other foods. In addition, self-made throat moistening tea is also a good choice, which can solve the problems of dry throat and cough and reduce the harm of air pollution to the lungs.

What can we do for the environment?

First of all, we should establish environmental awareness, which guides our behavior. Only with environmental awareness can there be real environmental protection actions!

Do you know that there are many things we can do to reduce environmental pollution in our daily life? Don't turn on the TV too much, don't turn on the air conditioner too low in summer, and you can save clothes to wash together. Have you done all this?

Third, choose energy-saving products (energy-saving light bulbs, energy-saving washing machines, energy-saving refrigerators, etc.). ) when choosing household necessities. These can save energy and electricity, which is a considerable extra income.

Fourth, we can choose household electricity and factory electricity, solar photovoltaic power generation and wind power generation, which are clean energy sources.

Through our hard study and application, and the government's strong support for environmental protection and sustainable development, I believe that with the joint efforts of citizens, the haze weather will eventually become history and our quality of life will be greatly improved.
