Smoking is hazardous to health, smoking secondhand smoke is also extremely harmful to the body. Especially at home with children, if parents smoke for a long time, in addition to children may suffer from acute and chronic rhinitis, hyperplasia, upper whistle infection secondary to otitis media, but also make the child “dumb” Oh! Second-hand smoke in the end how terrible 1, the child “become stupid”: long-term passive smoking will affect the child’s intellectual development. According to the latest scientific research, children who smoke passively for a long time, the IQ value drops by two points. Cotinine is a substance produced during the decomposition of nicotine, once the cotinine content in the child’s blood increases, their reading, math and reasoning ability will decline. If a child lives in a house with a smoker who smokes less than one pack a day, the cotinine level in his or her body will also reduce reading ability. 2, sudden death: secondhand smoke exposure can lead to sudden infant death syndrome in children, acute asthma attacks, whistling system disease, slowed lung function, middle ear disease, low birth weight babies, etc. 3, anorexia: American scholars have found that if a parent smokes while the child is eating food, it can make him or her nauseous and uncomfortable. When a child associates the feeling of nausea with certain foods to form a conditioned reflex, it will refuse to eat certain foods. 4, crying: German doctors found that parents smoking in the baby’s room, will significantly increase the number of babies crying. A scholar had surveyed 253 parents of children, where the father smoked less than 10 cigarettes a day, the child night crying accounted for 45%. 5, affect the height: scientists had 9273 children for 36 years of observation. According to statistics, children in families whose parents smoked more than 10 cigarettes a day were on average 0.65 cm shorter than children in non-smoking families; while children in families whose parents smoked less than 10 cigarettes a day were on average 0.45 cm shorter than children in non-smoking families. Data on the harmful effects of secondhand smoke on children 1. Secondhand smoke contains more than 40 carcinogens: Secondhand smoke is also known as environmental tobacco smoke (ETS). Secondhand smoke includes both mainstream smoke exhaled by smokers and tributary smoke that comes directly from paper cigarettes, cigars, or pipes. Secondhand smoke contains more than 4,000 substances, including more than 40 toxic substances that have been linked to cancer. Secondhand smoke is no less harmful to passive smokers than to active smokers. 2. Children’s cancer-causing levels are 1.6-8 times higher than those of adults: Because children’s detoxification capacity is much lower than that of adults, they are more vulnerable to the hazards of secondhand smoke. In the case of the same level of secondhand smoke exposure, children’s blood levels of cotinine (nicotine metabolites) are more than 1 times that of adults, and the level of carcinogens contained in tobacco in children’s urine samples is 1.6-8 times that of adults. 3, 180 million suffer from secondhand smoke: 180 million adolescents in China are exposed to secondhand smoke. Half of all children in the world (700 million) inhale tobacco-polluted air, resulting in more than 150,000 deaths per year from secondhand smoke exposure. 4, away from secondhand smoke, and return children to a healthy body: since we already know the dangers of secondhand smoke, for the sake of the next generation, to return the family, children a smoke-free environment, away from secondhand smoke, we can not wait. So, what can we do 1. at home: implement a family smoke-free plan (1) as parents, for the sake of their children’s health, they should consciously quit smoking and not swallow smoke at home.

Because even if the smoke dissipates, but the residual particles of cigarettes will cling to the cushions, sofa cushions, clothes, so clean in time to avoid excessive exposure to children. 2, in public places: choose a smoke-free area In many cities, has begun to implement the indoor smoking ban, there are also some places have a special smoke-free area. If you take your child out, parents may want to avoid places where smokers gather, and insist on choosing “no smoking areas” no matter where you are. If you are in a bus and someone is smoking next to you, try to open the doors and windows and circulate the air to reduce the concentration of smoke and harm to your child. When eating out, choose a restaurant that is smoke-free or has a smoke-free area. If the restaurant is not zoned, have your child sit in a well-ventilated area, far away from smokers. Mothers should also educate their children to build self-protection and stay away from people who smoke.
