The haze season is back. How much do you know about haze? Haze can also be called “Smog”. The word “smog” is from the words “smoke” and “fog”. It is a kind of air pollution(污染) mostly because of cars and factories.
Smog will do great harm(伤害) to your health. It can make you cough and have skin and eye problems. It seems that we can do nothing to stop it, but only wait until the wind blows all the smog away. However, there are some easy ways to stop it hurting you. Here are some of them.
1. Don’t do exercise in the open.
Exercising in the open makes you breathe(呼吸) deeply, and you will take in the particles(颗粒物) deep into your lungs.
2. Stay indoors and keep the air clean.
If you can, just stay in your room and keep the doors and windows closed. Remember to air your room twice a day, you can open the window at noon or at night for half an hour.
3. Wear a mask.
Paper and cotton masks can not help you in the haze weather. Some special masks, such as N95 masks, can keep you from breathing in the particles in the air.
4. Change your diet.
Scientists find that vitamin A, C and E can greatly help protect your eyes, nose and lungs. So eat more green vegetables and fresh fruit every day. What’s more, do not eat food with too much fat.
