What do you mean by foggy days? What is the reason for the formation? How to protect yourself?

The first question: the smog weather caused a large area of low visibility in the city. When the relative humidity is high in the morning or at night, fog forms; During the day, the temperature rises, the humidity drops, and it gradually turns into smog. This phenomenon has both meteorological reasons and pollution discharge reasons.

Second question: There are many factors, such as 1. When the atmospheric pressure is low and the air does not flow, it is the main factor. Because the air does not flow, the tiny particles in the air gather together and float in the air. 2. The ground is dusty and the air humidity is low. People and vehicles on the ground stir up dust. 3. Automobile exhaust is the main pollutant emission. In recent years, there are more and more cars in cities, and automobile exhaust is a factor of smog. 4. Secondary pollution produced by factories. 5. CO2 and other pollutants emitted by heating in winter.

The third question: 1. Have a happy outlook. 2. Under such foggy conditions, we can choose the amount of activity and the time to go out according to our own physique (such as reducing outdoor sports, etc.). Everyone has to go to work, so in this case, we should strengthen self-protection. First of all, smog weather has the greatest impact on our respiratory tract and should be protected. There is also changing clothes and washing hands frequently. We should pay more attention to our diet. Smog weather not only affects our respiratory tract, but also affects our skin to some extent. In this way, we should drink more water and eat more fruits and vegetables, which will not only help our respiratory tract, but also whiten and protect our skin. 5. Raise some plants. Generally, green plants have the function of purifying air. Choose some air purifiers to purify indoor air quality.

Hope to adopt, thank you!
