Expanding knowledge: the harm of tobacco
The smoke produced by tobacco combustion is a complex mixture of more than 7,000 compounds, of which gas accounts for 95%, such as carbon monoxide, cyanogen hydride and volatile nitrosamines, and particulate matter accounts for 5%, including semi-volatile and non-volatile substances, such as tobacco tar and nicotine. Most of these compounds are harmful to human body, of which at least 69 are known carcinogens, such as polycyclic aromatic hydrocarbons and nitrosamines, and nicotine is an addictive substance.
Secondhand smoke refers to the smoke emitted from the burning end of cigarettes or other tobacco products, which is usually mixed with the smoke emitted by smokers. Secondhand smoke contains hundreds of known toxic or carcinogenic substances, including formaldehyde, benzene, vinyl chloride, arsenic, ammonia and hydrocyanic acid. Secondhand smoke has been identified as a class A carcinogen by the US Environmental Protection Agency and the International Agency for Research on Cancer. Compared with the smoke inhaled by smokers themselves, the concentration of many carcinogenic and toxic chemicals in second-hand smoke is higher.
Smoking disease
Everyone knows that smoking is harmful to health, but most people don't know where it is harmful. In fact, smoking is not only harmful to the lungs, but also to the heart, bones and cells. And these injuries are gradually formed, unconsciously changed, and finally irreversible. Let's see what injuries we don't know about.
1, osteoporosis
A study of 465,438+0 pairs of twin sisters by doctors at the University of Melbourne in Australia confirmed that women who smoke have more fragile bones and are more prone to fracture in their later years. 4 1 Twin sisters, smokers and non-smokers, aged between 23 and 73, were paired, and the bone mineral density of their lumbar vertebrae, femoral neck and femoral shaft was measured. For women who continue to smoke as adults, the average bone mass index of smokers is 5% ~ 10% lower than that of non-smokers. Bone mineral density was measured every 10 year. Compared with non-smokers, the bone mineral density of lumbar spine is 2% lower, the femoral neck is 2% lower and the femoral shaft is 1.4% lower. Research shows that for every 65438 00% decrease in bone density, the bone strength decreases by 30%. Within 10 years, as long as the bone mineral density decreases 10%, the incidence of femoral neck fracture will increase by 44%. It is estimated in the United States that about 250,000 people are hospitalized every year for femoral neck fractures caused by osteoporosis, and the number of women is 6-8 times that of men. About 50,000 people die every year, which is the same as that of breast cancer. A study by Harvard Medical School in the United States shows that if women still smoke after menopause, the protective effect of estrogen therapy may be reduced. He said: "Women who smoke take estrogen and women who don't take estrogen have the same risk of hip fracture."
Step 2 promote aging
As early as 1928, Dr. Bohr of Hopkins Medical College put forward the theory that hypoxia can accelerate aging for the first time when studying cell biology. Smoking leads to long-term hypoxia in the body and decreased estrogen secretion, leading to premature aging. American scholars divide some smoking women of similar age into four groups according to the length of smoking time and the amount of smoking. The results show that long-term smoking leads to premature wrinkles in lips and corners of eyes, yellowing of teeth, rough skin, loss of elasticity and rich appearance, and premature signs of aging.
The age of smoking is gradually decreasing.
In China, the number of smokers is increasing and the smoking age is decreasing. Smoking is the most common among students. Smoking occurs from time to time in junior high school, and is the most serious in senior high school. It has become a habit in college.
The Report on China's Tobacco Control in 20 10 released by the China Center for Disease Control and Prevention last year showed that the smoking rate of teenagers in China was 6.3%, and the smoking attempt rate was 23. 1%. Peking University Institute of Child and Adolescent Health conducted a survey on 1 1957 junior high school students in Tianjin, Chongqing, Shandong and Guangdong provinces. The results show that among junior high school students aged 13~ 15, 32.5% boys and 13.0% girls have tried smoking. The average age of starting smoking is only 10.7 years old.
Therefore, we should always attach importance to anti-smoking propaganda, and we should not ignore the harm of smoking to teenagers.
What are the health hazards of smoking?
The eye-catching slogan "Smoking is harmful, please don't smoke for the health of you and others" can be seen everywhere in public places. Its function is obvious. It is to remind smokers to pay attention to public civilization and never smoke in public places, but many smokers turn a blind eye. Take the news as an example, stealing cigarettes in the train station toilet and ignoring the warning signs. This kind of behavior is not only harmful.
Smoking is a very common phenomenon in our life. There are always a few smokers around everyone. Indeed, smoking is not a big deal, and we can all understand it. However, smoking in public places and ignoring smoking signs still have a very bad influence. For non-smokers, they often smoke second-hand smoke in some public places, which is more harmful to human body. Sometimes we are also very upset, but we can't change the smoking phenomenon in public places.
