Is second-hand smoke harmful to smoking?

I usually start coughing when I smell cigarettes. Are secondhand smoke harmful? My husband has never stopped smoking since I became pregnant. When our children were young, we knew that secondhand smoke is bad, and we were afraid that it would affect their health. Every time we smoked, we would go outdoors to avoid them from breathing in secondhand smoke. Usually, I only know that secondhand smoke is very harmful, but I can't tell you what the specific harms are. In order to increase my knowledge, I read some books and then I understood some of the harms in this regard.

Compared with men, women are more harmed by tobacco. Some women who live with smokers have a 6 times higher risk of developing lung cancer than normal people. It should be noted that the risk of lung cancer for female smokers is more serious, which is 1.9 times that of male smokers. The harm of secondhand smoke to passive smokers is no less than that to active smokers, and it is especially serious for pregnant women and children. Studies have shown that if a person spends more than 15 minutes with a smoker every day, the harm caused by second-hand smoke is equivalent to that of a smoker. 75% of lung cancer patients can be traced back to smoking.

Nicotine and other harmful substances in smoke can stimulate the brain and cause hardening of cerebral blood vessels, thus affecting brain function. The intellectual development of children who are exposed to passive smoking for a long time is significantly worse than that of children who grow up in a non-smoky environment.

Non-smokers who were regularly exposed to secondhand smoke scored 20 percent lower on memory tests than another group of non-smokers. Smokers performed even worse, scoring 30 percent lower than non-smokers who were not frequently exposed to secondhand smoke.

Children are the biggest victims of environmental pollution, and the harm of smoking is most harmful to children. Children generally experience higher environmental exposures than adults because they breathe more air and, therefore, inhale more pollutants than adults. In addition, children are active, have poor self-protection abilities, and have incomplete immune functions, making them most vulnerable to harm from pollutants. If the father smokes at home, the children will not object at all, nor will they take any measures to protect themselves. They can only be forced to inhale secondhand smoke. However, the main hazards of secondhand smoke to children's health include: causing baby asthma, sudden infant death syndrome, bronchitis, pneumonia and ear inflammation.

Above, I told my friends some of the content I read in books about the harmful effects of secondhand smoke. Smoking is really harmful to the body, especially secondhand smoke. When you smoke, your family is also harmed. Some friends want to use smoking to relieve stress and fatigue from work and life, but for the health of your family and yourself, it is better to smoke less.
