How to reduce the harm of smog? How to reduce the harm of smog?
1. Reduce outdoor activities
When the smog weather is severe, the elderly and children should try to reduce the time and intensity of outdoor activities and wear masks when traveling. Wash your face and rinse your mouth before going home, and take off your coat to reduce pollution.
2. Wear a mask before going out
In order to prevent fog, you should wear a mask before going out in foggy days to prevent toxic fog from invading your lungs through your nose and mouth. People who have the habit of doing morning exercises should stop outdoor activities. Because 6: to 11: every day is a period of serious pollution, the air at night is relatively clean, so citizens with morning exercise habits may wish to put their exercise at night.
3. Close the windows
During the smog, try to close the windows and reduce indoor activities, especially those such as cooking and smoking, which lead to the decline of indoor air quality. If there is an air purifier at home, it should be turned on during the smog period, which is conducive to reducing the concentration of indoor harmful particles.
4. Open the window for ventilation after smog
When the smog in the outdoor atmosphere disappears, open the window for ventilation, so that the fine particles in the indoor air can be released as soon as possible to improve the indoor air quality.
5. Pay attention to personal hygiene
Due to the high concentration and small diameter of PM2.5 in the air in foggy days, it is easy to go straight into alveoli and carry bacteria and viruses into the respiratory system. When people's resistance drops, it will do harm to human health. In order to avoid influenza infection, it is suggested that sensitive people with basic diseases should be less in crowded places with dirty air, and pay attention to personal hygiene, wash their hands frequently, and increase or decrease clothes at any time to maintain good physical condition.
6. Pay attention to indoor hygiene
In foggy weather, we should pay special attention to indoor hygiene. Remember to open the window for air every day to ensure the air is fresh. Clean the room in time, clean up the sanitary corner, and don't give germs a breeding ground.
7. Regulate the mood. Diet is light
Due to the lack of sunshine, weak light and low air pressure in foggy days, some people will feel lazy and depressed in foggy days. I suggest you keep a scientific life rule, avoid overwork, drink more water, pay attention to a light diet, eat less irritating food, and eat more tofu, milk and other foods.
8. Take preventive measures
In order to prevent the harm of smog and increase the body's resistance, people can also make their own ginger and jujube soup (5-6 grams of ginger, 1 grams of jujube, and two bowls of water with brown sugar) to drink. This can enhance the human body's resistance to prevent fog damage.
9. Be more careful when driving and walking
In moderate and severe smog weather, visibility is low and vision is poor. People who drive, ride and walk should be more careful, especially when passing through intersections and unattended railway crossings, slow down and obey traffic rules to avoid traffic accidents.
1. Related knowledge of smog
1. What is smog
Fog: an aerosol system consisting of a large number of tiny water droplets or ice crystals suspended in the air near the ground, which is the product of water vapor condensation (or sublimation) in the air near the ground. The existence of fog will reduce air transparency and worsen visibility.
Haze: It is composed of dust in the air, smog weather graphic symbols, smog weather graphic symbols, sulfuric acid, nitric acid, organic hydrocarbons and other particles. It can also make the atmosphere turbid, blur the vision and worsen the visibility.
smog: it is a state of air pollution, and smog is a general expression of the excessive content of various suspended particles in the atmosphere. In many areas of China, haze weather phenomena are combined with fog as a warning and forecast of disastrous weather. Collectively referred to as "haze weather".
2. Causes of smog
Human factors: human activities will produce a large number of harmful gases and particles, which is a major cause of haze. Common factors that can cause haze are: automobile exhaust, substandard industrial gas emissions, coal burning in winter in northern China, dust from construction sites, etc.
natural factors: many factors in nature can also cause smog, such as the increase of static wind in the horizontal direction, inversion in the vertical direction and the increase of suspended particles and organic pollutants in the air.
3. Haze hazards
Fog: Fog seems mild, but it contains various fine particles and more than 2 kinds of toxic substances, including acid, alkali, salt, amine, phenol, dust, pollen, mites, influenza virus, tuberculosis, pneumococcus and so on.
Haze: The diameter of fine and powdery floating particles in haze is generally below .1 micron, which can directly enter bronchi and even lungs through respiratory system. Therefore, the biggest impact of haze is the human respiratory system, and the diseases caused are mainly concentrated in respiratory diseases, cerebrovascular diseases, nasal inflammation and so on.
