As we all know, smoking is harmful to health. The common diseases of smoking include lung cancer, bronchitis, emphysema, cor pulmonale, ischemic heart disease and other vascular diseases, as well as gastric and duodenal ulcers. The mortality rate of smokers is higher than that of non-smokers. 90% of lung cancer deaths are smokers. The more you smoke, the higher the death rate of lung cancer. The prevalence of gastric and duodenal ulcers is twice that of non-smokers. Teenagers are in a period of sudden growth and development, and all kinds of tissues and organs of the body need to be well developed. Their mental system, endocrine function and immune function are unstable, and their resistance and adaptability to external harmful substances are poor, so they are prone to various diseases. When cigarettes burn, many harmful substances (nicotine, cigarette tar, 3,4-benzophenone, carbon monoxide, etc. ) Smoking is more harmful to teenagers. The younger you smoke, the greater the harm. You are not only prone to colds, bronchitis and pneumonia, but also suffer from emphysema, pulmonary heart disease, chronic bronchitis and bronchiectasis like adults. Teenagers smoking is not only prone to various tobacco-related diseases, but also affects their physical and intellectual development. Physical examination shows that the height, chest circumference and vital capacity of smoking students are lower than those of non-smoking students of the same age. According to long-term observation, smokers are worse than non-smokers in flexibility, endurance, sports performance, academic performance and organizational discipline. In recent years, people began to pay attention to the influence of smoking on the learning and memory ability of the central nervous system and brain. In addition, the harm of "passive smoking (referring to non-smokers passively inhaling the prominent smoke of smokers)" has also attracted the attention of medical experts all over the world. Another problem worthy of attention is that many drug addicts mostly start from smoking. Therefore, teenagers should not only refrain from smoking, but also advise others.

I hate cigarettes, and I don't like to see others smoking, which is harmful to my health.

Smoking is an unhealthy living habit, and its harm to human body is as follows:

brain

Smoking can cause various brain diseases, reduce oxygen and blood circulation in the brain, lead to cerebral vascular bleeding and occlusion, and lead to paralysis, mental decline and stroke. The cause of stroke is that smoking leads to cerebral vasospasm, which makes blood coagulation easier. Smokers are twice as likely to have a stroke as nonsmokers.

laryngeal

Smoking can cause laryngeal cancer. Laryngeal cancer patients are mostly male.

Heart and blood vessels

Smoking can cause fat accumulation and vascular occlusion, making smokers prone to coronary heart disease. The death rate of heart disease caused by smoking accounts for 25% of the total. The prevalence of smokers over 50 has doubled. The prevalence rate of smokers under 50 years old increased 9 times, reaching 14 times. Smoking will constrict blood vessels, slow down the circulation of blood and oxygen, and eventually lead to thickening of blood vessel walls, leading to coronary heart disease and stroke. Smoking will completely block the blood circulation of hands and feet, leading to amputation.

lung

Smoking can cause lung cancer. 90% of the total mortality rate is caused by smoking. The prevalence rate of a person who smokes ten cigarettes a day is ten times that of a non-smoker. Damaged cells can't return to normal. The initial symptoms will not be found until the cancer cells spread to blood vessels and other organs. Smoking can also cause emphysema, and toxic substances accumulated in the bronchi of the lungs will hinder the normal exhalation of the air inhaled by the human body, make lung cells expand or rupture, and cause patients to have difficulty breathing.

stomach

People with gastrointestinal diseases, smoking is enough to make gastrointestinal diseases worse. People with gastric ulcer or duodenal ulcer will slow down the healing of ulcer and even become chronic diseases. Smoking can stimulate the nervous system, accelerate the secretion of saliva and gastric juice, make the gastrointestinal tract often tense, and lead to the loss of appetite of smokers. In addition, nicotine can also contract gastrointestinal mucosal blood vessels and reduce appetite.

skeleton

The recovery period of fracture of smokers is longer than that of non-smokers. It may be that nicotine and carbon monoxide contained in cigarettes slow down the process of bone regeneration. Nicotine constricts blood vessels and reduces blood flow to new bones. The carbon monoxide inhaled during smoking also reduces the speed at which oxygen enters the body. Smoking can lead to osteitis and back pain. Smoking more than ten cigarettes a day will double the prevalence of periostitis. Most people with severe back pain are addicted to smoking, because smoking will reduce the blood flow of the articular disc and the articular disc will degenerate early. Smoking can lead to arthritis. Smoking a pack of cigarettes a day will increase the prevalence rate by 50%. Female smokers are more likely to suffer from fractures and arthropathy after menopause. Smoking will lead to faster bone loss. Women smoke a pack of cigarettes every day from adolescence to menopause, and their bones are 5% to 10% less than those of non-smokers. When smokers enter menopause, the bone loss rate is faster. Smoking can interfere with estrogen, which is an important hormone in bone development.

bronchus

Smoking is the main cause of chronic obstructive tracheal disease. Because smoking can cause the cilia of bronchial epithelial cells to become shorter and irregular, cause dyskinesia, reduce local resistance and be susceptible to infection.

liver

Smoking will increase the burden on the liver. Regular smoking will affect the lipid metabolism of the liver, increase blood lipid, decrease benign cholesterol and increase malignant cholesterol. This has caused the burden of detoxification function of the liver to increase.

intestines

Smoking can lead to colon cancer. The risk of this kind of cancer is directly proportional to the amount of smoking. Research shows that although quitting smoking can reduce the risk of heart disease, lung cancer and other diseases, the risk of colon cancer is still high.

ocular region

Smoking can lead to cataracts and affect vision. Research shows that there are twice as many cataract patients who smoke more than one pack a day as those who never smoke.

genital system

Smoking inhibits the nerve center of the spinal cord, making men's sexual desire weak, and because smoking can make blood vessels contract and spasm, it causes peripheral blood circulation disorder. Therefore, smoking is the main cause of impotence. Australia and Canada have printed this information directly on cigarette packs. In addition, smoking will affect sperm motility and increase abnormal sperm, and it will take three to six months to return to normal after quitting smoking. If you want a smart and healthy child, baby experts advocate that you must give up smoking for three to six months.

Secondhand smoke

Secondhand smoke is a kind of mixed smoke that is burned or exhaled by cigarettes, pipes or cigars when smokers smoke. Secondhand smoke is the most common pollutant in many smoking places. Smoke emitted during smoking can release more than 4,000 kinds of gases and particles, most of which are very strong irritants, and at least 40 of them can cause cancer in humans or animals. After smokers quit smoking, these particles can still stay in the air for several hours, can be inhaled by other non-smokers, and may be mixed with the decay products of radon gas, causing great harm to human health.

When smoking harms smokers' own health, second-hand smoke will also affect non-smokers. In addition to irritating eyes, nose and throat, it will significantly increase the risk of lung cancer and heart disease in non-smokers. If children live with some smokers, their respiratory system will be more susceptible to infection. Other symptoms include increased cough, asthma, excessive phlegm, impaired lung function and slow lung development.

If you smoke, I hope you can quit smoking as soon as possible and stay healthy forever!

Drink moderately. Beer contains only 4% alcohol, which is less irritating and well received by doctors. Since ancient times, the right amount of wine has been regarded as "the length of a hundred medicines." As long as you drink it properly, but don't overdo it, alcohol is really good for your health, it can play a role in strengthening your body and preventing cardiovascular diseases. But if there is more than one glass of white wine every day, a bottle of beer will go bad and the health care effect will be zero. Moreover, daily overdose, regardless of the burden of the liver, will increase the incidence of heart disease. Therefore, scientists suggest that a glass of white wine and a bottle of beer every day, no more or less, are most beneficial to health. Drinking red wine or beer can reduce the occurrence of cardiovascular diseases, but drinking red wine has the best protective effect. Drinking red wine containing 22-32g alcohol every day can reduce the incidence of cardiovascular diseases and cancer by about 33%, while drinking red wine or beer, or both, is helpful to heart health as long as it is drunk in moderation every day. In a study, experts from King's College and St. Thomas Hospital pointed out that one of the best ways for young men and women to keep strong bones is to drink a glass of beer every day. Drinking beer every day can provide a lot of natural silicon, which is very helpful for bone health. In addition, hops, which make beer bitter, contain a female hormone, which has the functions of beautifying and relieving stress.

But what happens if you overdo it? Anything that you eat and drink too much will be harmful, and wine is no exception. Excessive drinking will make you susceptible to many other diseases, and drinkers are more likely to suffer from kidney disease and liver disease than ordinary people. Excessive drinking can cause alcoholism, damage the central nervous system and even paralysis of the medulla oblongata; Inhibit gastric juice secretion, weaken pepsin activity, stimulate gastric mucosa, make people suffer from chronic gastritis, and bring great harm to human body. Alcohol can also reduce the testosterone level of the main male, affecting male fertility and the health of future generations. For male teenagers, it can delay the maturity of sexual function. Excessive drinking by pregnant women may make the baby deformed, mentally retarded or even stillborn. For patients with liver disease, the stimulation of alcohol will increase the burden on the liver and aggravate the condition. For hypertensive patients who are taking antihypertensive drugs, alcohol will not only reduce the efficacy of drugs, but also dissolve the shell of slow-acting drugs, making drugs suddenly powerful and life-threatening. Generally speaking, every time people drink alcohol, when the alcohol concentration in the liquid reaches 0.05-0.2%, the inhibitory function of the brain is weakened, the memory is reduced, and the discrimination, concentration and understanding are obviously reduced. At this time, drinkers often lose their usual manners, become rude, talkative, boastful and even fight and make trouble. When the alcohol concentration in human blood reaches 0.4%, drinkers will fall into lethargy, coma, pallor, slow breathing, hypothermia and even lose their lives. Long-term heavy drinking can also cause chronic alcoholism, mental retardation, chronic gastritis, liver, heart, kidney degeneration, liver cirrhosis, polyneuritis and other diseases. People who often drink often don't pay attention to the nutrition of food. In addition, alcohol will consume thiamine (vitamin B 1) and nicotinic acid (anti-pellagra vitamin) in the body, leading to mental and organ disorders. Don't be careless People who drink too much are often malnourished. The experimental results show that even a small amount of alcohol will affect the short-term memory ability of normal people. Long-term alcoholics will suffer from severe amnesia due to vitamin B 1 deficiency.

So to sum up, you should try to control the number of 2-3 bottles within 1 bottle now, so as not to achieve a bad situation and put health first.
