Smog and cigarettes are more toxic.

Zhong Nanshan: Cloudy weather is more likely to cause cancer than cigarettes

"Cloudy weather is more likely to cause cancer than cigarettes." Zhong Nanshan, academician of China Academy of Engineering and director of Guangzhou Institute of Respiratory Diseases, once pointed out that in the past 30 years, the smoking rate of the public in China has been declining, but the prevalence of lung cancer has increased by more than four times. This may be related to the increase in haze days.

Zhong Nanshan emphasized that foggy weather with very low visibility will have an impact on human health. The composition of smog is very complex, including hundreds of atmospheric particles. Among them, aerosol particles with a diameter less than 10 micron are the main hazards to human health, which can directly enter and adhere to the upper and lower respiratory tract and lung lobes of human body, causing rhinitis, bronchitis and other diseases, and can also induce lung cancer in this environment for a long time.

Foggy weather is a hotbed of disease.

Smog weather can easily lead to upper respiratory tract infection, with cough, sneezing and runny nose as the main symptoms; Inhalable particulate matter, sulfur dioxide and other pollutants in foggy days are the main factors inducing asthma and chronic bronchitis. At the same time, it is cold and foggy in winter, and the air pressure is low, which is prone to hypoxia and ischemia, causing coronary vasospasm, thus inducing cardiovascular and cerebrovascular diseases.

Many harmful substances in smog do great harm to human skin and should be paid enough attention to. Especially after the harmful substances in the smog are attached to the facial skin with acne, it often causes various symptoms, such as facial itching, redness and inflammation.
