How to defend against smog weather

It is documented that medical masks can block 95% of 0.3 micron particles. Choose a regular and qualified mask, wear it at the same time, buy a model that matches the size of the face, and stick it on the skin to the maximum extent, so that contaminated particles cannot enter. The mask cannot be washed. After you take it off, you should wait until it is dry before folding it, so as to prevent the breathing moisture from breeding bacteria on the mask. The elderly and patients with cardiovascular diseases should avoid wearing it, because it is a professional anti-virus aerosol mask with good sealing performance, and it is easy to breathe and feel dizzy after wearing it.

2. Try not to ride a bike when going out.

Smog can temporarily reduce morning exercises and try to 10- 14 go out. At the same time, drink more water, smoke less, stay away from "second-hand smoke" and reduce the burden on organs such as lungs and liver. People who are used to riding bicycles and electric cars to work or going out for business should try to avoid the morning and evening rush hours of traffic jams and try to transfer to buses. This is because many chemical components in automobile exhaust are not completely burned and will float with fine particles in the air. When you ride a bike or an electric car, your body needs oxygen, and your lungs will inhale a lot of air.

When you enter the room, there are three things you must do.

The cleaning method is simple. Do three things well: wash your face, rinse your mouth and clear your nose.

It is best to wash your face with warm water, which can effectively clean the smog particles attached to the skin; The purpose of gargling is to remove dirt attached to the mouth; The key is to clean the nasal cavity. When cleaning the nasal cavity, be sure to absorb water gently to avoid choking. When cleaning the child's nasal cavity, parents can repeatedly wash the clean cotton swab with water.

4. Patients should go out less.

In this weather, reducing going out is the most effective way to protect yourself, especially for people with cardiovascular and cerebrovascular diseases and respiratory diseases.

Try not to open the window in foggy days.

Try not to open the window when the foggy weather escalates; If you really need to open the window for ventilation, try to avoid the morning and evening smog peak hours when opening the window. You can open a crack in the window to prevent the wind from blowing in directly, and the ventilation time should be half an hour to one hour at a time. Residents who use air conditioning for heating at home should pay special attention to window ventilation to ensure adequate indoor oxygen.
