编辑同志:近期,本地区常常出现大雾天气,我们很担心这是否会影响健康。有人说阴霾天气不但可能会对心脏、呼吸道有影响,还可能伤肺。那么请问,在这样的大雾天气中,我们的生活起居该注意什么?又该从哪些方面来保护呼吸系统呢?四川巴中读者年力 Editor’s Comrade: In the near future, there is often heavy fog in the region. We are very worried whether this will affect health. Some people say that haze weather may not only affect the heart and respiratory tract, but also may cause lung injury. So, I ask, in such a foggy weather, our daily life should pay attention to what? And from what aspects to protect the respiratory system?
