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. What is secondhand smoke Secondhand smoke (SHS) is commonly known as passive smoking. It is the act of involuntarily drawing smoke from other smokers. It is also known as "forced smoking" or "indirect smoking." Second-hand smoke actually consists of two kinds of smoke, one is the smoke that the smoker exhales, which is called mainstream smoke; the other is the smoke produced when the cigarette burns, which is called sidestream smoke. Non-smokers are second-hand smoke regardless of the type of smoke inhaled. How secondhand smoke harms the human body According to research, cigarette smoke contains more than 4,000 harmful substances in the smoke, which can be divided into four categories from the medical point of view: First, carbon monoxide, which is about four-tenths of the concentration in cigarette smoke, binds red blood cells by about 210 times the binding force of oxygen and red blood cells. Therefore, after carbon monoxide is inhaled into the human body, the ability of red blood cells to transport oxygen is reduced, and the body's ability Hypoxia. 2. Nicotine, which enters the body, has the following effects: contraction of peripheral blood vessels in the extremities, rapid heartbeat, increased blood pressure, rapid breathing, changes in mental status (becomes emotionally stable or emotional), and promotion of platelet aggregation. Cardiovascular obstruction, hypertension, stroke and other cardiovascular diseases are the main accomplice. Third, irritating substances, these substances will not only stimulate the eyes, nose and throat, but also stimulate the secretion of bronchial submucosal glands, leading to acute bronchial inflammation and chronic bronchitis. Fourth, carcinogenic substances, in addition to the recognized carcinogen nicotine, the smoke contains more radioactive elements, such as wolfberry, they volatilize when smoking, and as the smoke is absorbed by the body, accumulate in the body, and continuously release α rays, It damages the body's cells and destroys human immunity, creating an environment for the growth of cancer cells. Needless to say, the above four categories of harmful substances are also harmful to smokers and secondhand smoke inhalers. What is even more noteworthy is that some of the harmful substances in the shunting smoke are higher than mainstream smoke, such as carbon monoxide, and the shunting smoke is five times that of mainstream tobacco; tar and nicotine are three times; ammonia is 46 times; and nitrosamines (strongly Carcinogens) is 50 times. The results of the study also show that secondhand smoke has similar physical effects on smokers, because urine tests on secondhand smokers found that their urine also contained metabolites such as nicotine. Family is the worst hit area for secondhand smoke exposure Family is the harbor for everyone. It is the most solid line of defense for children and families. However, the “2015 China Adult Tobacco Survey Report†showed that 57.1% of the respondents saw smoking in their homes, second only to restaurants (76.3%). In addition, 54.3% of the respondents had seen workplace smoking during the past 30 days. Women of childbearing age passive smoking On November 6, 2012, the World Health Organization released data showing that more than one-half of women of childbearing age in China are often passively second-hand smokers. The "Global Adult Tobacco Survey" conducted by WHO and China and the United States Centers for Disease Control and Prevention shows that the number of women of childbearing age in China who regularly smoke secondhand in the workplace is more than half. At home, the exposure of second-hand smoke in rural Chinese women is even more serious. Nearly three-quarters of rural women are exposed to secondhand smoke at home, and more than half of urban women are exposed to secondhand smoke at home. The data also shows that in 14 developing countries including China, Brazil, and India, the exposure of second-hand smoke in women aged 15 to 49 is highest in China. According to Lan Ruiming, WHO Representative in China, "passive smoking in women of childbearing age can damage reproductive health, such as pregnancy complications, fetal premature birth and infant death." How to prevent secondhand smoke damage From the macro level, legislation is the ultimate means of effectively preventing the harm of secondhand smoke. However, from the perspective of the world, countries have made slow progress in this regard and the effect is not satisfactory. The "2007 China Controlled Smoking Report" also mentioned that compared with the results of the 1996 survey, the proportion of Chinese people exposed to secondhand smoke in public places has increased. Therefore, people who do not smoke should use their own means to prevent secondhand smoke harm. (1) In a regular smoking environment such as a home or office, a conference room, etc., it is best to actively take measures to eliminate or reduce air pollution, such as the use of air purification equipment, placing some green plants such as spider plants, ivy and so on. (2) In terms of diet, eat more fresh fruits and vegetables (especially rich in carotene and vitamin C) because vitamins have antioxidant properties and can fight cancer. Some vitamin E-rich foods can reduce the incidence of lung cancer by 20%, such foods include whole wheat bread, nuts, beans and grains. (3) drink plenty of water, more urination, more exercise, more perspiration, this can speed up the elimination of nicotine and other harmful substances in the body. (4) Tell the smoker friends and colleagues around you in a proper way that you don't like smelling smoke. The hazards of secondhand smoke are attracting more and more people's attention in the world. May 31 last year was the 20th World No Tobacco Day. The theme was “Creating a smoke-free environment†and expressed the determination of people to reject second-hand smoke. On World Cancer Day on February 4 this year, the World Health Organization confirmed the theme. For the purpose of creating a smoke-free environment for children, it is to make the public concerned about the health problems of 700 million children worldwide suffering from second-hand smoke. For the sake of the children's growth, for the health of those non-smokers who have never met, and for the smokers themselves, we advise smokers to smoke less or not to smoke cigarettes.
