Winter is here, and traffic jams in urban areas are becoming increasingly serious. People always like to open their car windows while waiting in line. Some car owners do it for ventilation, while others do it to save fuel. But in fact, it is best not to open the windows during traffic jams in winter. The damage caused by car exhaust to the lungs cannot be ignored, especially in winter when there is a lot of smog. If you encounter a traffic jam during the rush hour, the concentration of exhaust gas around the vehicle will be very high. At this time, Be sure to avoid opening car windows. Car owners are advised to open the windows to ventilate before starting the car. When encountering traffic jams, they should turn on the ventilation device in the car for "internal circulation" to avoid high-concentration exhaust gas from damaging the lungs. Likewise, cyclists or pedestrians are best advised to stay away from queues or pass as quickly as possible. At the same time, parents are advised not to use strollers to push their babies on the road, because the height of the stroller is exactly the height of exhaust emissions, which is quite detrimental to the health of the baby.

Places with severe traffic jams are narrow and crowded, with poor air circulation and high levels of benzopyrene. Benzopyrene is a gas with a special smell that is produced when burning gasoline, coal or smoking. Not only does it irritate the respiratory tract, it is also a carcinogen. In addition, due to incomplete combustion in the engine, other harmful substances will be produced in the air, such as benzene, toluene, xylene, suspended particulate matter, etc. Pollution on main highways and traffic light intersections is very serious. Main roads are prone to form strip-shaped pollution zones. The pollution level is centered on the main road and gradually weakens from the middle to both sides. At traffic light intersections, poisonous gases are released mainly when the engine starts when the light turns green. In fact, many people who encounter traffic jams open their windows to get some air because they are irritated. At this time, you might as well listen to music or chat to relieve your mood. You can also think about dinner recipes or plan your work for the week, so that you won't find the time in traffic jams unbearable.
