And when choosing a mask, you must choose qualified products and use thicker materials. Masks are easy to be contaminated when worn for a long time, so they should be cleaned and disinfected in time to ensure hygiene.

It's not too late to exercise until the sun comes out.

4. Drink plenty of water and eat lung-clearing food.

However, you still can't forget to wash your face and nose after going home to reduce the invasion of harmful substances and viruses into the human body through your skin and nose.

6. Don't open the window for ventilation in foggy days.

Drink at least 500ml more water every day than in other seasons. You can also pour hot water into the cup and inhale it through your nose at the mouth of the cup, every time 10 minute, 2 ~ 3 times a day, and directly "shoot" the water into the respiratory tract to maintain the normal humidity of the lungs and respiratory tract.
