How should we prevent haze weather?

Wear a mask

Literature records that medical masks can block 95\% of 0.3 micron particles. When choosing a mask, you must buy a regular and qualified one, wear it at the same time, and buy a model that matches your face shape and fit as tightly as possible to the skin to prevent pollution particles from entering. The mask cannot be washed. After taking it off, wait until the inside is dry before folding it in half to prevent the moisture from breathing in the mask from breeding bacteria. The elderly and people with cardiovascular disease should avoid wearing it because it is a professional anti-viral aerosol mask with good airtightness. After wearing it, it is easy to have difficulty breathing and feel dizzy due to lack of oxygen.

Try not to ride a bicycle when going out

Haze can temporarily reduce morning exercise. Try to go out between 10-14:00. At the same time, drink more water, smoke less and stay away from "second-hand smoke" to reduce the burden on the lungs, liver and other organs. People who are used to riding bicycles or electric vehicles to work or going out to do errands should try to avoid the morning and evening traffic congestion peak hours and try to take buses instead. This is because there are many chemical components in car exhaust that have not been completely burned and will float along with the fine particles in the air. When you ride a bicycle or electric bike, your body needs oxygen and your lungs take in a lot of air.

Three things you must do when entering indoors

The method of cleaning is very simple. Do three things: wash your face, rinse your mouth, and clean your nasal cavity.

It is best to wash your face with warm water, which can effectively clean the haze particles attached to the skin; the purpose of gargling is to remove the dirt attached to the mouth; the most important thing is to clean the nasal cavity. When cleaning the nasal cavity, be sure to gently sip water to avoid choking. When cleaning children's nasal cavities, parents can use a clean cotton swab dipped in water and wash repeatedly.

Patients should go out less often

In this kind of weather, going out less is the most effective way to protect yourself, especially people with cardiovascular, cerebrovascular and respiratory diseases, they should go out as little as possible Go out.

According to the study, after excluding factors such as age, gender, time effect and meteorological factors, when the fog concentration increases by 103 micrograms/cubic meter, the excess mortality risk of residents from all causes of death will increase by 2.29 \%, the lag time is 1-2 days. The excess risk of death increased by cardiovascular and cerebrovascular diseases is even higher, at 3.08\%.

Try not to open windows on hazy days

Try not to open windows when foggy weather escalates; if you really need to open windows for ventilation, try to avoid morning and evening fog when opening windows During the peak hours of haze, you can open the windows a little for ventilation to prevent the wind from blowing in directly. The ventilation time is preferably half an hour to an hour at a time. Residents whose homes are heated by air conditioners should especially pay attention to opening windows for ventilation to ensure sufficient indoor oxygen.
