Smoking is really harmful to your health. It is a cliche that smoking is harmful to health. Smoking is an important pathogenic factor of cardiovascular and cerebrovascular diseases, cancer, chronic obstructive pulmonary disease and other diseases. Smoking has become the second largest global killer after hypertension. In particular, smoking is the main risk factor for lung cancer. It is urgent to put an end to smoking! According to statistics, 5 million people worldwide die of smoking-related diseases every year. If not controlled, this number will reach100000 by 2020. At present, there are 350 million smokers in China, and about 1 10,000 people die of smoking-related diseases every year. According to 30,000 physical examination samples taken by Hua Zhao in 2006, at present, nearly 70% of male physical examination participants are smokers; Among female medical examiners, this figure also accounts for 8%. In the face of the international trend that the smoking population in developed countries is generally declining, why does China not fall but rise? The relationship between smoking and diseases. The relationship between smoking and lung cancer Many studies have proved that cigarettes are closely related to lung cancer. From 19 15, at that time, the cigarette consumption in the United States was1800 million cigarettes per year, and to 1984, the cigarette consumption increased to more than 600 billion cigarettes per year; The number of lung cancer deaths rose from 4,300 in 1.935 to 1.2 1.000. The consumption of cigarettes has always been directly proportional to the number of lung cancer deaths, so since 1935, lung cancer has become one of the main causes of death. Investigation shows that more than 80% of patients who died of lung cancer in China were caused by smoking and passive smoking. Second, the impact of smoking on the respiratory tract Because smoking can cause hyperplasia of trachea and bronchial glands, there will be ulcer inflammation in the small respiratory tract at the beginning of smoking, so smokers often cough and have phlegm. With the increase of smoking time, long-term exposure of mucocilia to cigarette smoke will hinder the ability of clearing away mucosal fibers in human respiratory tract and lead to acute bronchitis. Thirdly, the influence of smoking on lung tissue and function has been confirmed, and smoking can lead to emphysema. It is estimated that 80%~90% of the morbidity and mortality of chronic obstructive pulmonary disease are related to smoking. Smoking will reduce people's lung function, especially for heavy smokers. Fourth, the influence of smoking on cardiovascular system 1. Smoking is easy to cause blood vessel blockage, which leads to various diseases. 2. The burning of cigarettes will produce carbon monoxide, which will make people inhale about 400PPM of carbon monoxide, thus affecting the oxygen transmission function of blood. 3. Smoking will increase the total cholesterol and free fatty acids in the blood, which will lead to angiomatosis. Smoking doubles people's chances of suffering from heart disease. Each cigarette can produce more than 4000 compounds after burning, some of which are scattered in the air. Some of them are inhaled into lung tissue. These compounds include nicotine, tar, carbon monoxide, dozens of irritants and more than 40 carcinogens. Among them, nicotine has the function of central nervous system excitement and refreshing, and is the main substance that causes smoking addiction. In order to obtain nicotine, addicts inhale more toxic substances and carcinogens, causing cytopathic effects. In addition, nicotine can accelerate the heart rate, increase blood pressure, and cause peripheral blood vessels to contract. Long-term use can easily lead to cardiovascular diseases. Carbon monoxide will hinder the combination of normal oxygen and heme, leading to hypoxia in the body and even death in severe cases. Tar and irritants are the chief culprits of chronic obstructive pulmonary diseases such as chronic bronchitis and emphysema and various cancers. These substances are not necessary for us, and always endanger the health of drug addicts and second-hand smoke. Smoking or inhaling secondhand smoke during pregnancy can easily lead to stillbirth, increased neonatal mortality, birth weight loss, spontaneous abortion and premature delivery. Because the mother smokes during pregnancy, nicotine and carbon monoxide in the smoke can be transmitted to the fetus through the placenta, and the fetus is also injured, so that the fetus has been in this state, and the development of the fetus will naturally slow down. The harm of smoking to health is by no means alarmist. I hope that the majority of smokers will correctly understand the harm of smoking, and that there will be fewer smokers in China and more and more healthy people in China. For the health of you and your family, please give up smoking!
