Fog refers to the weather phenomenon that there are countless small water droplets or small ice crystals suspended in the air near the ground, resulting in horizontal visibility less than 500 meters. A large number of small water droplets or ice crystal particles are suspended in the air near the lower level, which makes people's vision blurred. When the horizontal energy distance of relevant personnel drops below 1000 meters, it is called fog.

Now scientists believe that fog is caused by the existence of "inversion layer", the atmosphere is stable, convection is weakened, and pollutants such as water vapor and dust in the air are not easy to spread to the sky and can only stay near the ground. When the fog drops dissipate, all pollutants will enter the air, causing serious pollution and directly endangering human health.

According to scientists' determination, the proportion of various harmful substances such as acid, alkali, salt, amine, phenol, dust and pathogenic microorganisms in fog drops is several times higher than that in ordinary atmospheric water drops. The harm of this pollutant to human body is most obvious in the respiratory tract. Therefore, people should not walk in the fog, let alone exercise in it.
