What are the hazards of secondhand smoke to the lungs

Everyone knows the harm of smoking to the body. Long-term smoking will have a direct impact on the body's respiratory tract and lungs. It may also cause serious physical dysfunction such as infertility. Therefore, quitting smoking is very necessary, and it is even more important for health. Secondhand smoke is also extremely harmful to the body. So what are the hazards of secondhand smoke to the lungs? Let us introduce it below.

According to experimental research results, the impact of secondhand smoke on the body is similar to that of smoking. For example: the incidence of lung cancer for a person who does not smoke but whose spouse smokes increases by 20% to 50%. For an innocent person living in an environment filled with environmental smoke, the risk of developing the disease is 20% to 30%.

Researchers recently published a research report pointing out that passive smoking, commonly known as "second-hand smoke", is more dangerous than the outside world originally knew. Some women who live with smokers have a 6 times higher chance of developing lung cancer than ordinary people.

The study, which examined tissues from 106 women in Missouri who lived with smokers, found that women whose gene, called GSTMI, was mutated or missing, were 2.6 to 6 times more likely to develop lung cancer than the general population. The GSTMI gene is currently believed to inactivate carcinogens in tobacco.

The harm of "second-hand smoke" is greater than imagined. Researchers said that this study is currently a small-scale experiment and needs further confirmation and expansion. However, if this study is correct, environmental smoking is a far more dangerous problem than previously thought.

The above introduces the harm of secondhand smoke to the lungs. After knowing the harm of secondhand smoke to the lungs, we should try to avoid smoking environments in the future, so as to reduce the harm of secondhand smoke to the body. It is very beneficial for maintaining good health. In addition, we should actively prevent the occurrence of lung disease symptoms in normal times.
