Can wearing a mask in foggy days really prevent smog from entering the lungs?

Ordinary cotton masks can't prevent smog, but people's psychological effects. If you want to prevent smog, you must use professional doctors' masks or anti-smog masks, which can isolate smog to a certain extent, but there is no way to completely prevent smog from entering the lungs.

1, the essence of smog

To prevent smog from entering the lungs, we must understand what the essence of smog is. Smog is mainly what we usually call PM2.5, and its impact on human health is not only the concentration, but also the time people spend in smog. Even if the smog is particularly heavy, our time outdoors is very short, and it will not have much impact on our health. Most of the smog is caused by some industrial wastes, automobile exhaust and thermal power plants. Ordinary gauze has no effect on it at all.

2. How to prevent smog

Although wearing a mask can play a certain protective role, it can't completely prevent smog from entering the lungs. Ordinary masks basically play the role of keeping warm and preventing colds in winter, but they have no isolation effect on PM2.5 At present, there are special anti-fog masks that can isolate smog, but the masks are ventilated and cannot be completely avoided. The best way is to go out less in foggy days and do less outdoor activities to avoid the harm of smog to the body.

3. How to keep yourself healthy?

If you want to stay healthy in a city with severe smog, you must pay attention to your exercise and living habits. Pay more attention to exercise at ordinary times, cancel morning exercise if possible, and choose a gym or gym for exercise. What we should pay attention to in life is diet. Try to eat some light food to relieve the stress on our bodies. It is best to give up smoking and drinking. These two things are particularly harmful, no less than smog.

I hope people can pay attention to environmental protection, maintain our ecological environment, reduce waste emissions and fundamentally avoid smog.
