(1) respiratory 1) Smoking can damage lung function, sputum and toxic substances can not be ruled out, bacteria reproduced. Long-term stimulation, the formation of chronic bronchitis and chronic obstructive airway, and further to the development of emphysema, coronary heart disease. 2) large quantities of tar smoke carcinogens attached to the respiratory tract, long-term stimulation can cause various parts of the respiratory tract cancer, lung cancer mainly Other oral cancer, lip cancer, larynx and so on. (2) the impact of smoking on the circulatory system 1) the nicotine content in cigarettes will enable faster heart rate, while systolic blood vessels, is high blood pressure; 2) blood vessels in the long-term contraction, leading to hardening of the arteries, luminal narrowing, reducing the transmission of blood; 3) nutrition myocardium after coronary artery, so that myocardial oxygen supply has been reduced, myocardial cell degeneration and necrosis, resulting in coronary heart disease; 4) Nutrition brain cells of artery hardening of the arteries, weakening of the vascular wall elasticity can be induced by cerebrovascular bleeding, luminal narrowing, and even cerebral thrombosis and cerebral embolism, resulting in "stroke"; 5) continued, a large number of inhaled carbon monoxide to make the body hypoxia, can increase the above diseases . U.S. scientists in recent years, according to research findings, from a health perspective, people once again to put forward a reason to quit smoking, with a view to arouse the people of the world attention. (1)Smoking not only endanger their own health, but also pollute the environment, endanger the surrounding non-smokers, especially women and children. Many people know that smoking damages health, but he did not know the seriousness of the health hazards of smoking. You quit smoking! (2)Smoking easily lead to insomnia, compared with non-smokers, smokers fall asleep and sleep more difficult. Nicotine in cigarettes can interfere with REM sleep, resulting in a decline in the quality of sleep. Smokers also more prone to snoring, daytime fatigue easy to doze off. (3)Smokers susceptible to diabetes, heart disease, a man's 42,000 study found that with the non-smokers compared to smokers occurred in non-insulin-dependent diabetes mellitus the possibility of higher than 1 percent. 30 ~ 40-year-old author of smokers suffered a heart attack than non-smokers of the same age 5 times high. United Kingdom A 46 000 cases of smokers in the survey found for the first time, young smokers the risk of heart attack increased significantly, while the volume of smoke containing medium tar cigarettes than those who smoke low-tar cigarette volume of the heart attack rate by 10 %. (4)Quitting smoking can reduce the risk of stroke, British scientists 7 264 middle-aged men study confirmed that a large number of smokers (more than 1 pack per day), 5 years to quit smoking can halve the risk of stroke. And smoking less than 1 pack per day, and 5 years to quit smoking can reduce the risk of stroke is not the level of smokers. (5)Long-term smoking can cause breast cancer studies have shown that women who smoke 30 years than any other woman to have a high risk of breast cancer 60 percent, which occurred in breast cancer, the average age is 59 years old, rather than for the 67-year-old smokers . (6)Smoking women with mild thyroid disease may increase the smoking would be a clear increase indigenous women suffer from mild thyroid disease may lead to thyroid failure. The study also found that women smokers, the average serum HDL (good cholesterol) lower than non-smokers, the former heart attack was significantly higher than the latter. (7)Smoking wrinkles caused by a 1 000 40 ~ 49-year-old population study found that female smokers noticeable wrinkles for female non-smokers 3 times is because smoking will damage those essential to maintain skin elasticity vascular connective tissue. (8)High incidence of lung cancer caused by smoking has been that men die of lung cancer and smoking is closely related to the recent study found that women die from lung cancer due to smoking also increased significantly. After a number of years to quit smoking is a safe point of view is wrong. Smokers to quit smoking has occurred in the duration of the risk of lung cancer than previously thought much longer. One study found that half of patients with lung cancer for people who have quit smoking. This is not to say no role to quit smoking, but warned that only the sooner the more security to kick the habit. (9)The best reason to quit smoking is to set a good example. As the 50-year-old who died of a heart attack 80% caused by smoking, so parents have to quit smoking as role models for the next generation. Family and community to deal with young people to carry out publicity and education on the hazards of smoking, research has proved that if the 19-year-old former non-infected with this nasty habit, then after a very small possibility of becoming habitual smokers.!
