What effect will fog bring to us?

1. Fog is one of the most influential weather for human traffic activities. The deterioration of visibility in foggy days is easy to cause traffic accidents. Among the traffic accidents in expressway, traffic accidents caused by bad weather such as dense fog account for about a quarter of the total, which has caused great losses to the country and people's lives and property.

2, fog will make cardiovascular patients worse, this is because on the one hand, the fog weather pressure is relatively low, people will feel irritable, blood pressure will naturally rise.

In foggy days, the temperature is often very low. Some patients with hypertension and coronary heart disease suddenly go from warm indoor to cold outdoor, and blood vessels expand with heat and contract with cold, which will also increase blood pressure, leading to stroke and myocardial infarction.

4. The air pollution is serious in foggy days, the fog is getting thicker in early winter, the air quality is poor, and the diabetic patients with poor resistance are very likely to have lung and trachea infections, which will aggravate the condition.

Extended data:

The conditions for fog formation are cooling, humidification and condensation to increase water vapor content. Fog mostly occurs at night and early morning when the sun is shining, the breeze is blowing gently, the water vapor near the ground is abundant and stable, or there is inversion.

There is indeed a foggy season in the sense of climatology in China, if the foggy season refers to a relatively foggy period in a year. However, due to the vast territory of China, there is no national fog season.

Because Chongqing is located at the intersection of the Yangtze River and Jialing River, there are many other rivers in the territory. Chongqing is very beautiful, and the average foggy day in the city is more than 170 days a year, so people give Chongqing the name of "Fog Capital".
