In addition to the parts directly stimulated by smoke, other parts can also suffer from cancer. According to research, 3,4-benzopyrene in smoke is very sensitive. After benzopyrene enters the ovary, the enzymes secreted by its tissues and cells can transform it into carcinogens, destroy oocytes, reduce mature eggs, and easily lead to ovarian cancer.
Among men who smoke, the risk of testicular cancer is much higher than that of men who do not smoke. The incidence of gastric cancer in smokers is 1.5 times higher than that in non-smokers.
In addition, some radionuclides in smoke, such as 2 10 polonium, 14 carbon and 40 potassium, are also seriously harmful to human body. Excessive deposition of polonium in renal tissue will cause renal cancer, and deposition in pancreatic tissue will also cause pancreatic cancer. Ethylenediamine in flue gas has a strong stimulating effect on bladder after entering the urinary system, which easily leads to bladder cancer.
In fact, cigarettes are not limited to carcinogens that cause cancer. According to medical experts, a cigarette contains hundreds of toxic substances harmful to human health, among which tar, nicotine, carbon monoxide and sulfur oxide are the most harmful to human health. Tar can cause lung cancer; Nicotine can excite nerves to contract blood vessels, increase blood pressure and reduce blood supply to tissues, and increase oxygen consumption of the heart by increasing heart rate, which is addictive. Carbon monoxide combines with hemoglobin in blood to form carboxyhemoglobin, which reduces the ability of blood to transport oxygen, makes smokers often in a state of hypoxemia, stimulates cell proliferation to increase oxygen carrying capacity, but the increase of red blood cells will increase the viscosity of blood at the same time, thus increasing blood flow resistance, reducing blood flow in heart and brain tissues, leading to cardiac hypoxia and cerebral ischemia. Long-term exposure to carbon monoxide and sulfur monoxide can also cause hypertension. They and nicotine-induced pulmonary artery wall thickening, coronary artery and cerebral atherosclerosis are the basis of pulmonary hypertension, coronary heart disease and cerebral ischemia in smokers.
For middle-aged and elderly people, accelerating the formation of arteriosclerosis and aggravating the pathological changes of arteriosclerosis vessels is undoubtedly a very important cause of coronary heart disease and cerebral ischemia. Hypoxemia, hypertension, decreased tissue oxygen supply and increased oxygen consumption in heart and brain caused by smoking are one of the main inducing factors for myocardial infarction and stroke in patients with arteriosclerosis.
Smoking not only causes hypertension, cardiovascular diseases, cor pulmonale and various lung cancers, but also has a great influence on fertility. There are more women who suck stillbirth during pregnancy, and the infant mortality rate is also high. Smoking in pregnant women can also affect children's intelligence. It is also common for men who smoke to suffer from impotence, because smoking will promote penile arteriosclerosis, reduce the number of sperm, reduce mobility and lead to infertility. Besides, passive smoking is also very harmful to people's health. It can be said that smoking is harmful to smokers and inhalers, so we should make up our minds to give up smoking resolutely.
Wine and cigarettes are slightly different. China has a long history of winemaking, and its wines are of high quality. Drinking has become a major hobby in people's lives, but a small amount of drinking at the right time is good for health. Such as yellow wine, glucose, fruit wine, beer, etc. These wines are low in alcohol content and rich in nutrition, and have the functions of refreshing the brain, helping digestion, warming the stomach, keeping out cold, promoting blood circulation and dredging collaterals, and can also reduce the occurrence of coronary heart disease and reduce the chance of vascular obstruction caused by fat deposition. This is in terms of a small amount of drinking. If you drink too much or drink too much for a long time, it will cause acute and chronic alcoholism and have a serious impact on human health.
Drinking alcohol can damage the nervous system, causing alcoholic psychosis and alcoholic hallucinations. The former is mainly manifested as memory loss and thinking disorder, mental trance, dull expression and slurred speech, which leads to mental disorder. The latter is mainly manifested in seeing and hearing hallucinations, nonexistent scenes in eyes, nonexistent sounds "heard" by ears, even horrible scenes, and impulsive behaviors such as hurting people and destroying things. The reason is that alcohol damages the brain parenchyma, and the brain can be regenerated after completely abstaining from alcohol.
The damage of drinking to the digestive system is mainly manifested in the damage to the liver and stomach. Alcohol is mainly oxidized and decomposed in the liver. Excessive drinking for a long time will reduce the oxidative decomposition ability of the liver, leading to the accumulation of alcohol in the liver and damage to liver cells. Leading to alcoholic hepatitis, alcoholic fatty liver and alcoholic cirrhosis. These are the most common diseases among alcoholics and the mortality rate is extremely high. A small amount of alcohol can stimulate gastric acid secretion and help digestion, while excessive alcohol can inhibit pepsin secretion, make people lose appetite and affect digestion. At the same time, the strong stimulation of gastric mucosa is easy to cause acute and chronic gastritis and gastric ulcer. Therefore, anyone with liver disease or stomach trouble should be forbidden to drink alcohol, otherwise it will aggravate the condition.
Drinking alcohol can also damage the circulatory system. Moderate dose of alcohol will cause vasodilation, rapid heartbeat, increase the oxygen consumption and burden of the heart, further myocardial ischemia with coronary atherosclerosis, and easily lead to angina pectoris, myocardial infarction, arrhythmia and heart failure. Long-term alcoholism or excessive drinking can increase myocardial adipose tissue, decrease cardiac function and increase the heart; Drinking a lot of beer for a long time will cause this kind of heart disease, which is called "beer heart". Blood lipids are deposited on the wall of blood vessels, the lumen of blood vessels becomes smaller, and blood pressure rises, which is prone to "drunken cerebral hemorrhage".
Alcohol is a gonadal toxin. Excessive drinking for a long time will destroy reproductive function, and men may have symptoms such as functional decline, impotence and infertility. Women can cause loss of libido, menstrual disorder, abortion, premature delivery, stillbirth and so on.
Excessive drinking for a long time can lead to the decline of respiratory defense function, which often leads to respiratory infectious diseases, such as laryngitis, acute and chronic bronchitis, bronchiectasis, bronchial asthma, tuberculosis, pulmonary infection and so on. Alcohol can also destroy the human immune mechanism, weaken the activity and phagocytosis of white blood cells, and is prone to various diseases. In addition, alcohol can also cause liver cancer, oral cancer, rectal cancer, breast cancer and so on. Even drinking low-alcohol drinks can lead to cell canceration, and the carcinogenic rate is 2 ~ 3 times that of not drinking.
Smoking and alcoholism are harmful to human health, and smoking and alcoholism are even more harmful to human health. This is because the smoke inhaled by smokers contains many chemicals, some of which are carcinogens. These chemicals are deposited in the mouth, nose, throat, lungs and other parts of smokers and become potential carcinogens. Alcohol can dissolve the tobacco poison that enters the human body, so that carcinogens can easily enter cells through mucous membranes, so people who are addicted to alcohol and tobacco are prone to cancer.
Alcohol and tobacco addiction not only consumes vitamin C and B 12 in the body, but also consumes vitamin B family, which affects the detoxification ability of the liver.
Heavy smokers drink too much, which is easy to cause alcoholism, thus causing malnutrition; In addition, the whole nervous system will be threatened and the death of brain cells will increase.
In addition, tobacco and alcohol addiction will increase the risk of hypertension and heart disease.
