Haze is a combination of fog and haze. Smog is very common in cities. In many areas of China, fog and haze are combined as disastrous weather phenomena for early warning and forecasting, which are collectively called "haze weather".

Haze is the result of interaction between specific climatic conditions and human activities.

Hazy weather is easy to induce cardiovascular diseases. Hazy weather, low air pressure, high humidity, the human body can not sweat, the probability of inducing heart disease will be higher and higher.

Induced respiratory diseases, smog contains a lot of particulate matter, which includes harmful substances such as heavy metals. Once it enters respiratory diseases and sticks to alveoli, it will cause nasal diseases such as rhinitis, pulmonary sclerosis and even lung cancer.

In foggy days, the light is seriously insufficient, the ultraviolet rays near the bottom are obviously weakened, and the bacteria in the air are difficult to kill, thus greatly increasing the probability of infectious diseases.

Due to poor air quality and low visibility in foggy days, rear-end collision accidents are prone to occur, which will affect the normal traffic order and bring inconvenience to everyone. We should observe the road conditions more during daily driving to avoid danger.

Haze weather has an important impact on roads, railways, aviation, shipping, power supply systems and crop growth. Fog and haze will cause air quality decline, affect the ecological environment and bring great harm to human health.
