1. Wear masks when going out
According to the literature, medical masks can block 95% of 0.3 micron particles. Choose a mask to buy a formal and qualified one, and wear it at the same time. Buy a model that matches the size of your face. It should be close to your skin to the greatest extent so that contaminated particles can not enter. The mask cannot be washed. After it is removed, it should be folded in half after it is dry, so as not to breed bacteria by breathing moisture. The elderly and people with cardiovascular diseases should avoid wearing it, because it is a professional anti-virus aerosol mask with good tightness. It is easy to have difficulty breathing and feel dizzy due to lack of oxygen.
2. Try not to ride a bike when you go out
There are many chemical components in automobile exhaust that are not completely burned through, which will float with small particles in the air. When you ride a bicycle or electric car, your body needs oxygen, and your lungs will breathe in a lot of air. Try to reduce the haze when you go out in the morning. At the same time, drink more water, smoke less and stay away from "second-hand smoke" to reduce the burden on lungs, liver and other organs. People who are used to riding bicycles or electric vehicles to work or go out to do business should try to avoid the peak hours of traffic congestion in the morning and evening, and try to take the bus instead.
1. Wash your face
It is best to wash your face with warm water, which can effectively clean the haze particles attached to your skin;
2. Gargle
The purpose of gargling is to remove the dirt attached to the mouth;
3. Clean the nasal cavity
Cleaning the nasal cavity is the key. When cleaning the nasal cavity, be sure to absorb water gently to avoid choking. When cleaning the nasal cavity of children, parents can dip a clean cotton swab in water and wash it repeatedly.
1. Don't go out
In this weather, reducing going out is the most effective way to protect yourself, especially for people with cardiovascular, cerebrovascular and respiratory diseases. According to the study, after excluding the influencing factors such as age, gender, time effect and meteorological factors, when the fog concentration increases by 103 μ g / m3, the excess death risk of all causes of death of residents will increase by 2.29%, and the lag time is 1-2 days. The increased risk of excess death from cardiovascular and cerebrovascular diseases was higher, which was 3.08%.
2. Try not to open the window
Try not to open the window in the case of fog weather escalation; If you really need to open the window for ventilation, you should try to avoid the peak period of haze in the morning and evening when opening the window. You can open a slit in the window for ventilation and prevent the wind from blowing in directly. 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 particular attention to opening windows for ventilation to ensure sufficient indoor oxygen.
Haze weather is a hotbed of diseases. In haze days, travel should be minimized and personal hygiene and other protection work should be done.
