What are the harms of secondhand smoke? Smoking is harmful not only to smokers themselves, but also to people around them. That is why smoking is now banned in public places for everyone's health. Below, China E-Cigarette News explains in detail the harms of secondhand smoke.
What are the harms of secondhand smoke?
"I don't smoke, but I'm exposed to smoking every day." While examining the health of smokers, we certainly cannot ignore the group of "passive smokers." Research shows that the health threats faced by passive smokers may be several times greater than those faced by smokers themselves. To understand this hazard, we need to start with "secondhand smoke."
What is secondhand smoke? Put simply, it refers to the smoke exhaled by smokers while smoking, or the smoke released when other tobacco products burn. It is also one of the most widespread and serious forms of indoor air pollution.
Professor Zhong Nanshan of the Department of Respiratory Medicine at The First Affiliated Hospital of Guangzhou Medical University stated that, to a certain extent, secondhand smoke may be even more harmful than firsthand smoke. The main reason is that after smoke is inhaled and then exhaled by the human body, what remains are tiny particles of about 1-2 microns. These particles can enter the alveoli directly, and because they are so small, the human respiratory tract cannot completely clear or block them. In addition, many of the residual components of secondhand smoke remain distributed indoors, leading to repeated inhalation by family members nearby. In other words, when men smoke, their families may unknowingly inhale secondhand smoke and become victims.
Data show that the number of women who do not smoke but develop lung cancer, as well as the likelihood of children developing congenital cardiovascular malformations, is gradually increasing. Much of this is linked to excessive exposure to secondhand smoke. Professor Zhong Nanshan recommends that smokers should first consider whether the smoking location is appropriate. Of course, the best option is to quit smoking altogether and create a healthy indoor environment for the family.
