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 richest way to produce free radicals. Each cigarette will produce at least 654.38+10,000 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.
A small amount of drinking is good for health.
A small amount of drinking can improve IQ. A study by the National Life Science Association in Aichi, Japan, found that the average IQ of men who drink less than 540 ml of Japanese sake or wine every day is 3.3% higher than that of men who don't drink. The IQ of female drinkers is 2.5% higher than that of teetotalers.
Drinking a small amount of alcohol can reduce the risk of heart disease. Dr ian wright from the London School of Hygiene and Tropical Medicine said: Drinking a glass of wine every day can reduce the risk of heart disease in men over 40 and postmenopausal women. In addition, alcohol can also increase the protective cholesterol in the body. At the age when drinking a small amount of alcohol is good for health, men will start at 35 and women will reach 55. This latest research shows that alcohol can only help the health of elderly men and women.
Drinking a small amount of alcohol can reduce the risk of dementia. Researchers from Eiras Morse University in Rotterdam, the Netherlands, conducted a six-year follow-up survey on 5395 elderly people over 55 years old (including 55 years old) who had no signs of dementia. The results show that people who drink 65,438+0 ~ 3 glasses of wine a day have lower risk of dementia than those who don't drink.
Even a small amount of drinking is harmful to health.
A small amount of drinking will increase the incidence of 60 diseases. Epidemiological evidence shows that studies carried out around the world since 1970 have proved that a small amount of drinking (65438+ 0 ~ 2 cups a day) can reduce the risk of coronary heart disease in elderly men and women by about 20% ~ 30%, but even a small amount of drinking will increase the chance of injury and contribute to about 60 diseases, such as various tumors, cirrhosis and nerves.
A small amount of drinking will have a bad effect on the brain. A study published by American scientists also shows that whether it is light or moderate drinking, it will inevitably have a negative impact on these people's brains. People who drink between 1 ~ 6 glasses a week are considered as light drinkers, while moderate drinkers drink more than 7 glasses a week. According to the results of magnetic resonance imaging, light and moderate drinkers do cause brain atrophy after drinking. The study also found that this situation does not distinguish between men and women, nor between races.
No matter how much asthma attack it can induce, some data show that it is harmful to asthma patients, no matter how much alcohol they drink or how high or low their alcohol level is. This is because alcohol can not only cause allergic diseases, but also induce asthma attacks.
