Does The Harm Of Second-hand Smoke Really So Serious? Answer: Yes.
Oct 26, 2018

Smoking is harmful to human's health. Although more and more people are aware of the dangers of smoking, they still can't resist the fatal attraction of swallowing clouds, and the innocent people between them who are forced to inhale second-hand smoke.

Secondhand smoke, also known as passive smoking, refers to people who do not smoke to absorb the smoke of other smokers, also known as forced smoking. As the lyrics say, when smokers hurt their health, they also hurt the health of passive smokers. Studies have shown that more than 3/4 Chinese people have not fully understood the health hazards of secondhand smoke.

China is the country with the largest tobacco production and consumption in the world. The smoking rate of males is as high as 53% and that of females is 2.4%. But this does not mean that women are less harmed by tobacco. The Global Adult Tobacco Survey released in 2010 shows: China's second-hand smoke exposure is very serious, 72.4% of non-smokers are exposed to second-hand smoke, and nearly 740 million people are exposed to second-hand smoke, including a large number of pregnant women and children.


First, there is no doubt that a large number of studies have shown that smoking affects the quality of male sperm, whether it is direct smoking or second-hand smoke. In a study of 2016, male smokers were found to have more severe DNA damage than non-smokers, and smokers had lower sperm quality, resulting in lower pregnancy rates or increased fetal malformations.

Some scholars have done animal models of male mice, put the mice in a confined environment, smoke 2 cigarettes a day for 6 weeks, equivalent to one person taking 20 cigarettes a day, and found cigarette smoke on passive smoking mice. Fertility has a significant effect,  and the average survival and survival rate of the offspring mice are significantly lower than those of the non-smokers.

In a study conducted in Sweden in 2015, the researchers reviewed 44,853 records and found that even if the mother had no history of smoking,  grandmother smoking during pregnancy was still a risk factor for asthma  in children. Compared with the average child, the risk of asthma in children with a history of smoking exposure during pregnancy increased from 10% to 22%. In other words, the dangers of smoking and secondhand smoke can even affect grandparents.


When people talk about the harm of tobacco to the human body, they pay more attention to men because the male is the main group that is harmed by tobacco in people's minds. However, as the times progress and lifestyle changes, women are increasingly affected by tobacco hazards, especially second-hand smoke. The study found that secondhand smoke is one of the major risk factors for increased  respiratory morbidity and mortality, especially for women and children.

Husband smoking increases the risk of spouse's illness, and second-hand smoke is as high as 0.54 in women's lung cancer scores. In addition, domestic and foreign literature supports secondhand smoke as one of the dangers of female atherosclerosis.

What we not only need to do is to stay away from second-hand smoke, but what we need to do is to quit smoking.
