Car exhaust is also very harmful to the lungs Most people understand that smoking is the main culprit of lung cancer, but in fact, dust and air pollution in living and working environments, chronic lung diseases and genetic factors can also lead to lung cancer. Just as many men can develop lung cancer from smoking, fumes can cause lung cancer in women who cook a lot. With cars entering homes in large numbers rapidly, the damage to the lungs from car exhaust cannot be underestimated. Especially in winter, when there is a lot of hazy weather and traffic jams during the peak hours of commuting, the concentration of exhaust gas in the surrounding “local area” is very high, so be careful not to open the windows. Car people are best to start the car before opening the windows to change the air, when encountering traffic jams, should be the car ventilation device for “internal circulation” to avoid the high concentration of exhaust gas on the lungs. Likewise, cyclists or pedestrians are best to stay away from the “long line of cars” and should pass quickly when they can’t avoid it. Parents had better not use the stroller to push the baby on the road, because the height of the stroller is the height of exhaust emissions, which is quite detrimental to the baby’s lung health.
