Smoking, smoking is harmful to health, but everyone knows it, but there are still so many people smoking? Some people think smoking is a bit handsome, while others do it to relieve their worries. How intoxicated they are when they see others smoking! I'm in a bad mood recently, and I smoke! It seems that smoking can eliminate my sadness and make me less depressed. But I found myself even sadder! Not only did it not eliminate my sadness, but it intensified in a movie! Friend, please don't smoke for your health and for people who care about you! Smoking does a lot of harm. It not only devours the health and life of smokers, but also pollutes the air and harms others. 1. Lung diseases: 38 kinds of toxic chemicals are released when cigarettes are burned, among which tar, carbon monoxide, nicotine, dioxins and irritating smoke are harmful components. Tar is harmful to the mouth, throat, trachea and lungs. Tar in tobacco smoke is deposited on lung villi, which destroys the function of villi, increases phlegm and causes chronic bronchial diseases, such as tracheitis, emphysema, pulmonary heart disease and lung cancer. According to statistics, the proportion of smokers suffering from lung disease after 60 years old is 74%, while the proportion of non-smokers suffering from lung disease after 60 years old is only 4%, which is a shocking figure. Second, cardiovascular diseases: carbon monoxide in cigarettes reduces the oxygen content in the blood, causing hypertension and other related diseases. Smoking will contract coronary artery, reduce or block supply, and lead to myocardial infarction. Smoking can increase adrenaline, make the heart beat faster, 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. Third, smoking causes cancer: The study found that smoking is the fastest and most free radical generation method, and each cigarette will produce at least 654.38 million free radicals, which will lead to cancer and many chronic diseases. Recently, a 50-year study was conducted on 35,000 smokers at Tidcliffe Hospital in Oxford, England. The results show that lung cancer, gastric cancer, pancreatic cancer, bladder cancer, liver cancer, oral cancer and sinus cancer are "significantly related" to smoking. Why smokers catch a cold easily is because the activity of lymphocytes in the human body decreases, leading to cancer. In view of the three major factors leading to smoking and cancer, the sooner you quit smoking, the better. Fourth, smoking can also lead to osteoporosis and early menopause. Smoking can make men lose their sexual and reproductive functions. Smoking in pregnant women will lead to premature delivery and underweight of the fetus, and the probability of miscarriage will increase. Smoking makes teeth yellow, which makes bad breath easy. Smoking harms people, and the harm of passive smokers is five times that of smokers. For the health of you and your family, you should quit smoking as soon as possible. Fifth, the harm of smoking to intelligence. Smoking will affect people's attention. Some people think that smoking can refresh the mind, eliminate fatigue and inspire, which is totally unreasonable. Experiments show that smoking seriously affects people's intelligence and memory, thus reducing the efficiency of work and study. Smoking is harmful to nothing. 53% of children in China smoke passively, which is even more harmful and prone to pneumonia, bronchitis, severe asthma and other diseases. If the current smoking situation continues, children's intellectual development, families and individuals who smoke will pay a huge price.
