As we all know, smoking is harmful to our health. Smoking bears the brunt of the damage to the human lungs, which is more likely to increase the risk of lung cancer and even affect the life cycle of a person.
People who smoke will live longer? After 50 years of investigation, British experts announce the truth or subvert cognition
Fifty years ago, almost no one believed that cigarettes and lung cancer were related, and that the high incidence of lung cancer was caused by air pollution, until a British scientist named “Richard Dole” turned his attention to tobacco.
In 1951, Richard Dole conducted a 5-year experiment among British male doctors. The experiment included 34,439 doctors and was published in the British Medical Journal. It was the first time that there was a clear relationship between smoking and lung cancer. The more you smoke, the higher your risk of lung cancer.
The study was carried out until 2004, and the statistical results are released every 10 years. Results released in 2004 showed that 11% of non-smoking 70-year-olds among the subjects lived to the age of 90.
In the 1990s, this proportion rose to 32%, but these effects will be offset by smoking. Studies have pointed out that smoking will shorten a person’s life expectancy by an average of 10 years. Richard Dole also emphasized that quitting smoking at any age is meaningful.
Richard Dole was originally a smoker. After he came to the conclusion that smoking causes cancer, he made up his mind to quit smoking. Later, he lived until he was 93 years old. He was called the “Godfather” of the anti-tobacco campaign.
Tobacco is an important factor in inducing lung cancer; a long, long-term backlog is more likely to cause irreparable damage to various organs, so the sooner you quit smoking, the better the recovery of the disease.
The dangers of long-term smoking, it is recommended to know early!
1. Lung disease: When cigarettes burn, they release 38 kinds of toxic chemicals, among which the main harmful ingredients are tar, carbon monoxide, nicotine, dioxin and irritating smoke. Tar can damage the mouth, throat, trachea, and lungs. The tar in tobacco smoke is deposited on the villi of the lungs, destroying the function of the villi, increasing sputum, causing chronic bronchial lesions, bronchitis, emphysema, pulmonary heart disease and lung cancer.
According to statistics , the proportion of smokers who suffer from lung diseases after the age of 60 is 74%. while the proportion of non-smokers who suffer from lung diseases after the age of 60 is only 4%, which is a shocking figure.
2. Cardiovascular diseases: The carbon monoxide in cigarettes reduces the oxygen content in the blood, causing related diseases such as high blood pressure. Smoking constricts the coronary arteries, reduces or blocks the supply, and causes myocardial infarction.
Smoking can increase adrenaline, cause rapid heartbeat, increase heart load, affect blood circulation and lead to cardiovascular and cerebrovascular diseases, diabetes, sudden death syndrome , decreased respiratory function, stroke and more than 20 kinds of diseases.
3. Smoking causes cancer: Studies have found that smoking is the fastest way to generate free radicals, and each puff of a cigarette will produce at least 100,000 free radicals, which can lead to cancer and many chronic diseases. A 50-year study of 35,000 smokers by the Ti dcliff Hospital in Oxford, UK, concluded that:
Lung cancer, gastric cancer, pancreatic cancer, bladder cancer, liver cancer, oral cancer, sinus cancer, etc. 11 cancers are “significantly correlated” with smoking. The reason why smokers are prone to colds is that the activity of lymphocytes in the human body is reduced, which leads to cancer.
4. Smoking can also lead to osteoporosis and early menopause. Smoking can make men lose sexual and reproductive function. Smoking in pregnant women can lead to premature birth and underweight fetuses, increasing the chance of miscarriage. Smoking turns teeth yellow and makes bad breath easy. Smoking harms others, and passive smokers are five times as harmful as smokers.
5. The harm of smoking to intelligence. Smoking can affect one’s concentration. Some people think that smoking can refresh you, eliminate fatigue, and trigger inspiration, which is completely unscientific. Experiments have proved that smoking seriously affects people’s intelligence and memory, thereby reducing the efficiency of work and study.
Smoking has 100 harms but no benefits. 53% of children in China are passive smokers, which is more harmful and prone to pneumonia, bronchitis, severe asthma and other diseases. If the smoking situation continues, children’s mental development, smoking families, and individuals will pay a great price.
The term “second-hand smoke” first appeared in 1996, but unfortunately it has not attracted enough attention. “Secondhand smoke” refers to exposure to environmental tobacco smoke for more than 15 minutes at least once a week. Studies have found that if a person inhales secondhand smoke for more than 15 minutes a day, his risk of developing lung cancer is the same as that of a smoker.
“Third-hand smoke” refers to tobacco smoke residues on surfaces such as clothes, walls, carpets, furniture, and even hair and skin. These substances can react with common air pollutants like nitrous acid to form powerful carcinogens.
Statistics show that some people who live with smokers are 6 times more likely to develop lung cancer than ordinary people. “If the husband smokes, the wife’s risk of developing lung cancer will increase by 30%;
Children inhaling second-hand smoke not only affects their development, but also easily induces a series of diseases such as bronchitis, pneumonia, and even tumors. It can really be said that “one person smokes, and the whole family suffers.”
