What harm does secondhand smoke do to the body every day?

Secondhand smoke is more harmful. American medical researchers recently published a research report that passive smoking, commonly known as second-hand smoke, is more dangerous than previously known. Some women who live with smokers are six times more likely to develop lung cancer than ordinary people. After examining the tissues of 65,438+006 women living with smokers in Missouri, this study found that women with a gene mutation called "GSTMI" or lacking this gene are 2.6 to 6 times more likely to develop lung cancer than the general population. At present, the gene "GSTMI" is considered to inactivate carcinogens in tobacco. "Secondhand smoke" is more harmful than imagined. The researchers said that this study is a small-scale experiment and needs further confirmation and expansion. However, if this study is correct, the problem of environmental smoking is far more dangerous than previously known. Lung cancer is considered as a civilized disease by the medical community, because its severity is constantly emerging with the progress of society. Since the 20th century, the incidence of lung cancer has greatly increased, and the growth rate is faster than other cancers. In the 1920s, there were only over 370 cases of lung cancer reported in the world, but by the 1950s, the number of people suffering from lung cancer in the United States alone was as high as 1830. Preventing lung cancer is better than treating lung cancer. The most common symptoms include long-term cough, even bloodshot sputum, chest discomfort, chest tightness, persistent cold symptoms or bronchitis, and even difficulty breathing. Lung cancer metastasizes quickly, and the cure rate is worse than other cancers such as nasopharyngeal carcinoma. The treatment of lung cancer includes surgical resection, radiotherapy and chemotherapy. Regarding the prevention of lung cancer, it is wisest to stay away from cigarettes and cigarettes. At the same time, not only try not to smoke, but also don't let yourself get second-hand smoke. Even in public places, try to avoid smokers and avoid the harm of second-hand smoke. Regarding the prevention of lung cancer, the National Cancer Institute recently published a report that some foods rich in vitamin E can reduce the chance of smokers suffering from lung cancer by 20%. The researchers said that the study found that people with the highest vitamin E content in their blood had a lower risk of lung cancer. People who smoke for the shortest time and have high levels of vitamin E in their blood have the best preventive effect. But experts also pointed out that vitamin E, which has the function of preventing lung cancer, mainly comes from food and whole wheat bread, rather than vitamin E supplements. Foods rich in vitamin E include hard fruits, green vegetables, beans and cereals. Tobacco harm is one of the most serious public health problems in the world today. At present, there are 1 1 100 million smokers in the world, and the annual death caused by tobacco is estimated to be1100,000. Every 10 second, one person dies from the harm of "cigarettes". How to reduce the harm of second-hand smoke is related to the health of smokers themselves and the sustainable and healthy development of social environment. Smoke emitted by smoking can be divided into mainstream smoke (that is, smoke inhaled by smokers) and tributary smoke (that is, smoke emitted when tobacco is lit). Cigarettes contain more tobacco burning components than mainstream cigarettes. Among them, carbon monoxide and tributary flue gas are five times that of mainstream flue gas; Tar and nicotine are three times; Ammonia is 46 times; Nitramide is 50 times. According to calculation, in places with poor ventilation, the amount of cigarettes inhaled by non-smokers within 1 hour is equivalent to the average dose of 1 cigarette. Non-smokers who smoke passively for more than 15 minutes every day are defined as passive smoking, also known as "forced smoking" or "indirect smoking". In daily life, most people can't completely avoid contact with smoke, so they become passive smokers. According to the results of the national smoking sampling survey, 39.75% of the 343,563 non-smokers were harmed by passive smoking. Passive smoking accounts for 67. 1% at home, 14.4% at work or other public places, and 18.96% at home and public places every day. The main places of passive smoking are family (7 1.2%) and public places (32.5%). Passive smoking is especially harmful to infants, teenagers and women. For children, passive smoking can cause respiratory symptoms and diseases, affecting normal growth and development; For pregnant women, passive smoking can lead to stillbirth, miscarriage and low birth weight infants; Passive smoking also increases the risk of respiratory diseases, lung cancer and cardiovascular diseases in adults. In addition, the problem of second-hand smoke may produce a series of "relationship crises". Smoking in the family environment and smoking in the office environment is likely to affect the harmony between people. In order to let us all have a fresh living space. On the one hand, smokers should try to smoke fewer cigarettes with high tar content and try to control the quantity of cigarettes. Smokers and "second-hand smoke" should strengthen health care, such as taking more vitamin E supplements and doing more physical exercise. On the other hand, we should pay attention to smoking less in public places, especially in indoor spaces with poor ventilation conditions, so as to reduce the pollution to the breathing environment of ourselves and others. It is best to take active measures to eliminate or reduce air pollution in the environment where people smoke frequently, such as homes, offices and conference rooms. For example, put some green plants such as chlorophytum and ivy, or use air purification equipment. In addition, passive smokers should strengthen their awareness of rights and interests, make full use of the rights conferred by laws and regulations, and discourage smokers in indoor environments such as offices and families.
