What are the harms of smoking to the human body

Smoking is a very bad lifestyle habit, and this lifestyle habit is an important cause of major diseases in the body. So in normal times, if you want to keep your body healthy. Then we need to maintain relatively good living habits. Quitting the smoking habit can also be a great help to others. So what are the harms of smoking to the human body? Today we will tell you about it in detail.

1. Lung disease: When cigarettes burn, they release 38 toxic chemicals, among which the main harmful ingredients are tar, carbon monoxide, nicotine, dioxins and irritating smoke. Tar is harmful to the mouth, throat, trachea and lungs. The tar in tobacco smoke is deposited on the villi of the lungs, destroying their function, increasing sputum, and causing chronic bronchial lesions, leading to tracheitis, emphysema, cor pulmonale, and lung cancer. According to statistics, 74% of smokers suffer from lung diseases after the age of 60, while the proportion of non-smokers suffering from lung diseases after the age of 60 is only 4%. This is a shocking number.

2. Cardiovascular disease: Carbon monoxide in cigarettes reduces the oxygen content in the blood, causing related diseases such as high blood pressure. Smoking causes coronary artery vasoconstriction, reducing or blocking the supply and causing myocardial infarction. Smoking can increase adrenaline, causing the heart rate to accelerate, increase the heart load, affect blood circulation and lead to more than 20 diseases such as cardiovascular and cerebrovascular diseases, diabetes, sudden death syndrome, decreased respiratory function and stroke.

3. Smoking causes cancer: Studies have found that smoking is the fastest and most effective way to produce free radicals. Every puff of cigarette produces at least 100,000 free radicals, which can lead to cancer and many chronic diseases. A 50-year study of 35,000 smokers at the Tidcliffe Hospital in Oxford, UK, concluded that 11 types of cancer, including lung cancer, stomach cancer, pancreatic cancer, bladder cancer, liver cancer, oral cancer, and sinus cancer, are "significantly correlated" with smoking. The reason why smokers are more likely to catch colds is because the activity of lymphocytes in the human body is reduced, which leads to cancer. Given the three major factors that cause smoking and cancer, the sooner you quit smoking, the better.

4. Smoking can also cause osteoporosis and early onset of menopause. Smoking can cause men to lose their sexual and reproductive functions. Smoking during pregnancy can lead to premature birth and low birth weight of the fetus, and increase the chance of miscarriage. Smoking yellows teeth and causes bad breath. Smoking harms both yourself and others, and people who are exposed to passive smoking suffer five times more harm than smokers. For the health of you and your family, do not let yourself become a slave to smoking and quit smoking as soon as possible.

5. The harm of smoking to intelligence. Smoking can affect a person's concentration. Some people believe that smoking can refresh people, eliminate fatigue and trigger inspiration, which is completely unscientific. Experiments have shown that smoking seriously affects people's intelligence and memory, thereby reducing work and study efficiency.

The above are the harms of smoking to the human body. Now that we know so much about the harmful effects of smoking on the body, we should actively quit the smoking habit. This is the only way to keep the body in a healthier state. Reduce the incidence of diseases. Quitting smoking also plays a very important role in the health of others, so I hope everyone can actively quit smoking.
