There are hundreds of millions of smokers in China, and a large number of people suffer from respiratory diseases and lung diseases every year because of smoking, which is one of the reasons for the high incidence of lung cancer in China. However, some people retort that many long-lived elderly people living in mountainous areas, 90 years old or even 100 years old, still keep the habit of smoking every day. It can be seen that smoking not only does not make people sick, but also has the function of health care and disease prevention. I often meet such people around me. One told him that smoking was not good and advised him to give up smoking as soon as possible. The other party will always come up with such and such reasons and try to prove the theory that smoking is harmless. This view has hurt many people. A large number of clinical data prove that more than 80% of lung cancer is related to long-term smoking. And long-term smokers, the average life expectancy will be reduced by 12 years! There may be an old man with two long lives who have the habit of smoking, but this case is of little reference value. For men over 50 who have smoked for more than 20 years, the probability of lung cancer in these people is more than 10 times higher than that in non-smokers. In addition to being harmful to the lungs, the probability of long-term smokers suffering from cardiovascular diseases, osteoporosis, hypertension and other diseases will also increase. Studies have found that even the vitality of men will be reduced because of smoking, on the contrary, the deformity rate of men who smoke will increase. This is why doctors advise men to quit smoking during pregnancy. In life, the harm of smoking to the body will be doubled in certain characteristic time periods: 1, and the harm of smoking after meals will be doubled: some people say that "a cigarette after a meal is better than a living fairy", but a cigarette after a meal may shorten your life! After meals, the stomach digests and absorbs food, and the blood flow in the body is accelerated. At this time, continuous smoking will accelerate the entry of harmful substances and affect the digestive function of the stomach. 2. Smoking when staying up late is twice as harmful to the body: whether working late or playing games late, many men have the habit of smoking a cigarette to "refresh themselves" when staying up late, often smoking several packs of cigarettes a night. Staying up late for a long time itself increases the probability of cardiovascular disease. At this time, heavy smoking is more harmful to blood vessels. And when staying up late, it is usually in a closed room, and the air is not circulating. At this time, a large number of carcinogens and toxic substances produced by cigarette burning spread in the indoor air. Even if you enter the room the next day, you will still smell this smell, which means that toxic substances will continue to hurt you. Dear friend, do you have the habit of smoking?
