The problem of smog(雾霾) is becoming more and more serious. But that should not stop you from enjoying your life. Here are some ways for you to keep the smog away.

Pay attention to the weather report.

The weather report will show you information about air pollution. Here is the rule: if the reading(读数) is above 80, remember to wear a face mask and limit your time outside; if it reads below 80, go outside and enjoy the day, open all the windows to get some fresh air, and exercise. But do not exercise outside if the reading is high. I went running once when it was around 120, and I got ill because of that and missed several days of work.

Get some house plants that clean the air.

Not only can plants make your home more beautiful, they can also clean the air. Just choose the plants you like, and those which can make your body feel good. If you still don’t know what plants to get, turn to the cyber world for help. I am sure you will get the answer you want online.

No matter how hot and wet it is inside, close the windows unless it is a nice day. Of course pollution may come in itself, but there is no need to help it get inside. What about the bathroom? I advise you to take short showers so as not to make your home wet, and also keep the windows closed.
