Under air pollution, there are two kinds of people who are facing higher health risks: First, people with congenital or acquired physical susceptibility, such as pre-existing diseases or health conditions, are more responsive to air pollution exposure. Secondly, people with higher air pollution exposure levels are also more vulnerable.
The following people usually have higher health risks:
1, people with existing diseases
2. Children and pregnant women
3, the elderly
4. Outdoor workers
It should be noted that pregnant women, children and the elderly, as well as patients with cardiovascular and cerebrovascular diseases or respiratory diseases, should minimize short-term air pollution exposure. Reducing long-term exposure to air pollution is very important for everyone.
Should people stay indoors during the period of serious air pollution?
Staying indoors may be beneficial to avoid air pollution, but its effect depends largely on indoor air quality. Air pollutants may seep into the room from the outside, and there are many potential air pollution sources in the room itself, such as cooking, smoking, second-hand smoke, burning incense and so on. At the same time, factors such as indoor ventilation type and architectural characteristics also participate in the influence of indoor air quality.
3. During the period of air pollution, are the groups with health risks advised to reduce physical activity?
Generally speaking, even if the air quality in a certain place is poor, regular physical activities should be advocated. When possible, people should adjust the time and place of sports activities to reduce air pollution exposure. Patients who are taking medicine should follow the doctor's advice.
According to the precautionary principle, people who are exposed to specific risks due to health or occupational reasons should be informed of the best time and place for sports activities or outdoor work. In the case of serious air pollution, moderate-intensity physical activity or outdoor work should be reduced.
4. How to use a mask in the case of air pollution?
Filter mask is mainly made of filter material, which is the most common air particle purification mask. The mask should cover the nose and mouth, closely fit the face, and can filter PM2.5 particles and smoke.
According to the relevant suggestions and regulations on occupational protection, to ensure the effectiveness of masks, the following five conditions need to be met:
1, worn correctly
Step 2 make sure it's appropriate
3. Always wear it when exposed.
4, timely replacement
5. Confirm whether the mask can filter 95% air particles.
Proper selection and use of masks can reduce the inhalation of pollutants. However, people with respiratory diseases should be cautious, because wearing masks may aggravate the existing diseases.
