What harm does car exhaust do to men's health? With the improvement of people's living standards, cars have entered thousands of households, but one thing we cannot ignore is the harm of car exhaust to health. Many studies have found that car exhaust can lead to male infertility.
In recent years, the number of urban cars has increased sharply at a rate of about 13% per year, and the pollution of urban car exhaust is becoming increasingly serious. Long-term inhalation of car exhaust can reduce the vitality of men's sperm.
Nowadays, with the increasing social pressure, male infertility is also on the rise. Sperm is the key to male pregnancy, and the poor quality of sperm is certainly one of the reasons for male infertility, but this is only part of the reason. There may be other reasons for male infertility.
Male infertility is an important hidden danger affecting male health, and air pollution is a major environmental risk affecting health. Italian research has shown that long-term exposure to traffic pollution can reduce male sperm motility, which in turn affects their fertility. Exhaust gas can also affect male fertility.
"If a man is exposed to traffic pollution for at least six hours a day, his testosterone and other hormones are not low in secretion, but his sperm's ability to swim can be low, affecting their ability to bind to eggs.". In addition, nitric oxide and lead in automobile exhaust gas are the most likely to damage sperm quality. Heavy metals in exhaust gas, such as lead, mercury, and cadmium, are also major enemies of spermatogenesis.
During traffic jams, many people habitually open their windows to breathe. However, the exhaust pollutants emitted by automobiles generally gather in a zone 40 to 50 centimeters above the ground. This height means that if a person in a car opens a window, they will inhale high concentrations of exhaust gas emitted by the vehicle, and if they open a window, even a sunroof, the impact on the person in the car will be the same.
Although automobile exhaust pollution is serious, it is also possible to open the windows for ventilation when the air is humid, such as in rainy and snowy weather. However, during commuting hours, traffic jams are most severe, and you should avoid opening any windows at this time. When encountering weather with poor air circulation, such as overcast and foggy weather, the impact of air pollution is also serious after opening the window
