Fog and haze are the most serious in the second half of the year. How did the fog and haze come from?

Every year in the deep winter, there will be serious smog problems in many areas of China, mainly in North China. Many people are curious about how smog is produced, and what is the difference from fog?

First of all, smog is a mixture, which contains inhalable particles, which will cause harm to the human body. Many people will confuse it with fog, which is made up of water droplets, so there is a big difference between the two.

How is the smog produced? First of all, with the improvement of people's living standards, it is more and more convenient to travel by car, but it leads to a lot of automobile exhaust and makes the air quality worse and worse. This is the culprit. It is concentrated in North China because of the local terrain restrictions, and some particulate matter can not be dispersed in time and accumulated, which will lead to smog. High-rise buildings will also hinder the diffusion of particulate matter, so smog weather will occur in many cities, and it is precisely because of the inversion phenomenon that the combination of the two will lead to the current situation.

Is smog harmful to human body? The answer is yes. Inhalation of a large amount of particulate matter will have an impact on human immune function, making people vulnerable to virus infection, affecting lung function and even leading to cardiovascular and cerebrovascular diseases.

In order to avoid being hurt by smog, you must wear a mask when you travel, and don't go out for activities in foggy days, especially in the morning when the smog is serious, and morning exercise can't achieve its due effect. On the contrary, it will cause harm to the body by inhaling a lot of air during exercise, because it must be noted that many people are bored at home in foggy days and want to open the window for ventilation, which is impossible. In addition, drink more hot water and eat fruits to supplement vitamins in foggy days.

Now the country is already controlling smog. First, limit coal burning and reduce pollutants. At the same time, we will restrict cars, vigorously develop new energy vehicles, and at the same time give preferential treatment to new energy vehicles. But this is not enough. It is a long-term task and needs our joint efforts.
