How to prevent the harm of haze weather

The elderly, children and people susceptible to respiratory diseases with weak resistance should try to reduce going out or outdoor activities, and wear masks to protect their bodies when going out to prevent pollutants from invading the lungs through the nose and mouth. After returning from going out, you should immediately wash your face and expose your skin.

2. Wear a mask and go out less.

Wear a mask when going out, but it is best not to wear it for more than 4 hours. Cloth masks should be cleaned and disinfected with boiling water every day. Some personalized masks and cartoon masks are only one or two layers thick, so it is difficult to filter viruses and dust in the air. Common masks such as N95 and KN90 have a good protective effect on PM2.5, but they are not suitable for children. Disposable masks should not be used repeatedly to avoid secondary pollution.

3. Close the doors and windows to purify the air

Try to close the doors and windows in foggy days, and you can open the window for a short time when there is plenty of sunshine and less pollutants at noon. The installation and use of air purifiers can improve indoor air quality to some extent, and products that do not produce by-products such as ozone should be selected.

Step 4 put green plants indoors

Planting some green plants indoors can absorb carbon dioxide in the air and produce oxygen.

5, pay attention to diet

Patients with chronic respiratory diseases, especially the elderly, should keep scientific life rules, avoid overwork and drink plenty of water. Pay attention to a light diet, eat less irritating food, eat more tofu, milk and other foods, and supplement vitamin D when necessary.

6. Be careful when driving and walking.

Moderate and severe haze weather, low visibility and poor line of sight. People who drive, ride and walk should be more careful, especially when passing through intersections and unguarded railway crossings, to slow down and obey traffic rules to avoid traffic accidents.
