Presumably there are many people living under the influence of secondhand smoke. Do not underestimate secondhand smoke, but the harm is great. So, in the end how much harm does secondhand smoke have? How much harm is there? How can we reduce the risk of secondhand smoke? Now we will witness it together.
Second-hand smoke causes many health hazards, including increasing the risk of cardiovascular disease, cancer, and respiratory diseases in adults, increasing asthma in children, and triggering pneumonia, otitis media, and even behavior problems in children. Especially for pregnant women and teenagers, you have more harm than expected.
1, lung cancer
Second-hand smoke contains more harmful substances than mainstream smoke. For example, it has twice as much nicotine, three times as much tar, five times as much carbon monoxide, and about 50 times as many carcinogens. According to calculations, the amount of smoke inhaled by non-smokers within one hour is equivalent to the average amount of inhaled cigarettes in places with poor ventilation. According to the survey, smokers have a significantly higher chance of developing lung cancer than non-smokers. Through analysis of the smoke inhaled by smokers, smoke was found to contain dozens of carcinogens. The risk of lung cancer is related to the length of smoking. The earlier you start smoking, the greater the risk. The longer the smoking time, the higher the incidence and mortality of lung cancer.
Women suffer more from tobacco than men. Some women living with smokers are six times more likely to develop lung cancer than normal people. What needs to be reminded is that the risk of lung cancer among females is even more serious, which is 1,9 times that of male smokers suffering from lung cancer. Secondhand smoke is no less harmful to passive smokers than active smokers, especially to pregnant women and children. The study pointed out that daily and smokers stay together for more than 15 minutes, the harm of those who smoke “secondhand smoke†is equivalent to smokers. Seventy-five percent of lung cancer patients are ultimately responsible for smoking.
2, the harm to memory
Harmful substances such as nicotine in the smoke stimulate the brain to harden the cerebral vasculature, and brain function can be affected. Children who have long-term passive smoking develop significantly less mental development than children who grew up in non-smoky environments.
Non-smokers who are often exposed to second-hand smoke are 20% less likely to score in memory tests than non-smokers in another group. Smokers performed worse and scored 30% lower than non-smokers who were not exposed to second-hand smoke.
3, trigger children asthma, pneumonia, ear inflammation
Children are the biggest victims of environmental pollution. Children often experience higher environmental exposure than adults, who breathe more air than adults and inhale more pollutants. Coupled with children's agility, poor self-protection, and inadequate immune function, they are most vulnerable to contaminants. If Daddy smokes at home, the child will not do anything against it at all, nor will he do something to protect himself. He will only be forced to use secondhand smoke. However, the harms of secondhand smoke to children's health mainly include baby asthma, Sudden Infant Death Syndrome, bronchitis, pneumonia and ear inflammation.
4, coronary heart disease
Smoking causes heart disease. This applies not only to those who actually smoke, but also to non-smokers exposed to secondhand smoke. Exposure to second-hand smoke can cause acute coronary heart disease. Even a short-term exposure to second-hand smoke can increase the risk of coronary heart disease. This is biologically certain.
Smoking increases the risk of coronary heart disease in men by 4 to 6 times, compared with 6 to 9 times in women. Exposure to environmental tobacco smoke increases the risk of heart disease death in non-smoking women. Secondhand smoke causes coronary heart disease and ischemic stroke in women. The incidence of peripheral vascular disease increased significantly. The cause of coronary heart disease caused by passive smoking is that chemical substances inhaled by passive smoking can cause dyslipidemia, thick blood, destruction of myocardial tissue, decrease blood vessel regulation of blood pressure and blood flow, and increase the risk of myocardial infarction.
5. Harm to pregnant women and babies
Ninetine and other harmful substances can be detected in 95% of pregnant women's uterine amniotic fluid that passively smokes secondhand smoke, indicating that tobacco smoke directly pollutes the womb's growing intrauterine environment. Exposure to secondhand smoke is an important risk factor for pregnant women with pregnancy-induced hypertension and pregnancy complications. At the same time, second-hand smoke exposure has a serious impact on the body's health from the beginning of the fetal period. Exposure to secondhand smoke also affects the proliferation and differentiation of embryonic cells, leading to abnormal embryonic development, manifesting in developmental disorders of the nervous system and intrauterine growth retardation.
If mothers inhale secondhand smoke for a long period of time during pregnancy, most of the harmful chemical substances released when the tobacco burns can pass through the placenta to “harass†innocent babies. Especially toxic gases such as carbon monoxide will reduce the oxygen concentration in the mother's body, which in turn will lead to fetal hypoxia. Nicotine, an addictive drug in tobacco, will cause narrowing of blood vessels and slow blood flow, which means that the blood supply to the fetus The nutrients and oxygen will be reduced, and it is easy to cause premature infants. However, premature babies are prone to dysfunctions such as breathing, digestion, and body temperature regulation, and even die soon after birth.
6, pharyngitis
Long-term secondhand smoke is a common cause of chronic pharyngitis. The tar, nicotine, nicotine and other harmful substances in the smoke can inhibit the activity of respiratory cilia, weaken the purification ability of the respiratory tract, cause hyperemia and edema in the bronchial mucosa, and cause external pathogens to enter the bronchi and cause repeated infections at the site, leading to Chronic pharyngitis.
Second-hand smoke is more harmful than smoking, because smoke contains more harmful substances than smokers absorb into the body. Long-term smoking of secondhand smoke contains more carbon monoxide and nicotine than smokers. I am more likely to suffer from chronic pharyngitis than others.
7, leading to female infertility
From a clinical point of view, smoking can adversely affect female reproductive functions, sexual function, and endocrinology, and increase the risk of infertility. Clinical investigations have shown that direct smokers and secondhand smokers are 2.7 times more likely to suffer from infertility than nonsmokers. At the same time, smoking can also seriously impair women's reproductive function, leading to a lower chance of women becoming pregnant. If both men and women smoke at the same time, the pregnancy rate of women will be lower.
8, leading to leukemia and tumors
A study in the United States showed that husband smoking can increase the odds of a non-smoking wife suffering from leukemia by 7 times. Women who are passively smoking at home from 6 to 45 years old are 3-4 times more likely to have breast and cervical cancer than women in non-smoking families.
Due to the carcinogenic substances of tobacco, adults and children suffer from blood diseases, especially the proportion of leukemia. According to statistics, smokers inhaled benzene is 10 times higher than non-smokers, and therefore smokers are 6-7 times more likely to suffer from leukemia than non-smokers; Xinhua Hospital children's leukemia statistics show that more than 60% of leukemia patients Children have secondhand smoke pollution. This shows that smoking plays an important role in the pathogenesis of leukemia.
