Recently, I read the news that smog weather produces a lot of PM2.5, which will reduce people's life span. Is it true?/You don't say. So what can be done to avoid it?

Statistics show that particulate matter will significantly increase the mortality rate. People began to pay attention to PM2.5 relatively late, so I estimate that there are few such long-term studies on life span. I looked it up on SCI for you, and there was only one related article, and the conclusion was that "there is no substantive basis to draw the conclusion that there is a causal relationship between long-term environmental PM2.5 and mortality increase", that is, there is no substantive basis for long-term environmental PM 2.5 and mortality increase.

However, we can basically be sure that high concentration of PM2.5 will endanger human health. There are solutions, but they are not immediate. As an ordinary citizen, I think what we can do is (copy and paste my other reply):

1, smoke less, smoke less secondhand smoke, smoking is much more harmful than pure particulate matter, and it will also produce a lot of particulate matter.

2. Ensure a good indoor air environment, because people spend more time indoors.

3. When the air is polluted, reduce going out, wear a mask when going out, and don't do strenuous exercise (strenuous exercise inhales more particles, and the probability of particles entering the bronchial end is higher).

4. Protect the environment, starting with me. Advocate less private cars and green travel to contribute to PM2.5 emission reduction.

I believe that the present situation of air pollution in China will continue to improve. At the same time, we should also know that the control of particulate pollution is a protracted war, and we can't rush for success.

The above answer is another copy of my answer, saying that you can't believe everything the media says, so you should make your own rational judgment.
