What inconvenience does smog bring to people's travel?

Haze weather has an impact on human respiratory tract, which may cause acute upper respiratory tract infection (cold), acute tracheobronchitis, pneumonia and asthma attacks, and induce or aggravate chronic bronchitis. In particular, children's respiratory mucosa of nose, trachea and bronchus is tender, and the number of alveoli is small, the development of elastic fibers is poor, and the interstitial development is vigorous, which makes them more susceptible to respiratory viruses. Being in foggy weather for a long time will cause tracheitis, laryngitis, pneumonia, asthma, rhinitis, conjunctivitis, allergic diseases, etc., which will have a certain impact on the growth and physique of children and adolescents.

In East China and Central North China, the haze weather is high. When smog is seriously polluted, highways around the country will even be closed, which will easily lead to frequent traffic accidents on national highways and provincial highways and traffic jams everywhere. Drivers must pay attention to safety when driving, turn on fog lights and emergency lights, and drive carefully. Don't drive too fast or take the retrograde road.
