What harm does wine do to human body and brain?

Wine is a poison that permeates the intestines. Why discuss its harm? The ancients had such knowledge. Besides, people nowadays have such knowledge. Since it must be harmful, don't drink it. If you can't control it, you can drink a little wine. Whether it is beneficial or harmful to the cardiovascular system is controversial. Some alcoholics drink more and more on the grounds that alcohol can pass through blood vessels, and their addiction to alcohol is growing. There is a qualitative and quantitative problem of not knowing the benefits of alcohol on cardiovascular system, that is, drinking a small amount of low-alcohol is beneficial to the prevention of cardiovascular diseases, while drinking a large amount is harmful to health. Some experts believe that the prevalence and mortality of coronary heart disease in a small number of drinkers are lower than those in non-drinkers, which is related to the fact that a small amount of drinking can increase HDL-C in blood and inhibit platelet aggregation. Among many liquors, red wine is superior to white wine and other liquors in preventing cardiovascular diseases. As for the amount of alcohol consumed, it is best not to exceed 50 ml per day. It is reversible that the systolic function of healthy people can be reduced after drinking alcohol. In addition, drinking alcohol can also accelerate the heart rate and dilate peripheral blood vessels, which is unfavorable to some patients with cardiovascular diseases. Some healthy people may have supraventricular or ventricular arrhythmia after drinking a lot. Because it mostly happens after drinking heavily on holidays, this syndrome is called "holiday heart disease", which is caused by alcohol and sympathetic nerve excitement, and can gradually return to normal after abstinence. Long-term heavy drinking will lead to heart failure, which is characterized by enlarged ventricles and low left ventricular systolic function. The appearance and regression of pathological changes are related to drinking. After stopping drinking, heart failure can be improved or at least not further deteriorated, and it will recur after drinking again. If this happens repeatedly, it will cause irreversible damage to the myocardium, even after abstinence, there will be progressive deterioration of heart function, which will lead to "semen cardiomyopathy". In addition, the incidence of atrial fibrillation in alcoholics is also high. This kind of atrial fibrillation caused by alcoholism can be reversed or stabilized if alcohol can be stopped early. Alcohol is a food with pure heat energy. Long-term heavy drinking will increase weight, affect the process of glucose metabolism in the body and increase the production of triglycerides. Obesity and hyperlipidemia are both risk factors for coronary heart disease. Therefore, long-term heavy drinking will increase the prevalence and mortality of coronary heart disease in heavy drinkers. It is not difficult to see that drinking a small amount of low-alcohol wine has positive significance for preventing cardiovascular diseases; Drinking a lot of hard liquor for a long time is extremely harmful to health. In view of the harm of drinking to digestive system, central nervous system and reproductive system, and a series of traffic and social problems that may be caused by drinking, relevant experts suggest not to take moderate drinking as one of the measures to prevent cardiovascular diseases. Advise you not to drink too much, and middle-aged people with drinking habits should limit and reduce drinking; On holidays or when friends and relatives get together, it is advisable to drink low-alcohol wine. Patients with cardiovascular diseases must abstain from drinking alcohol, and children and adolescents should not drink alcohol. In addition to the immediate impact of one-time excessive drinking (commonly known as drunkenness), repeated heavy drinking will also cause a variety of serious long-term diseases. We summarize the effects of drinking on various organs of the human body as follows. A small amount of alcohol in the brain can make people feel excited, alert and focused, but the actual results show that this is not the case. Drinking a small amount of alcohol has a sedative effect, while drinking more alcohol has serious harm to memory, attention, judgment, function of municipalities directly under the central government and emotional response. Drinking too much can lead to slurred speech, blurred vision and loss of balance. Long-term heavy drinking in the liver will inevitably lead to cirrhosis. The diseased liver can no longer handle nutrients from the digestive tract and drugs ingested by the human body. There are many symptoms of cirrhosis, and they are diffuse. These symptoms include edema (fluid stagnation, bloating) and stomach jaundice (yellow skin and white eyes). Skin alcohol is a vasodilator, which can dilate blood vessels on the body surface. In addition to making you look flushed, it will also make your body tissues radiate heat excessively, which will cause you to feel cold (hypothermia) in cold weather. People who drink heavily in the heart will develop cardiomyopathy, which means that the muscle tissue of the heart becomes weak and damaged. One-time heavy drinking in the stomach will make you feel uncomfortable with acute gastritis, and continuous heavy drinking will lead to more serious chronic gastritis. Alcohol in reproductive organs can lead to male impotence. For pregnant women, even a small amount of alcohol will increase the risk of physical defects of unborn babies. How much is drinking too much? The question should be: how much wine is enough to drink? The influence of alcohol on the body and mind depends on its concentration in the blood. Alcohol enters the blood through the digestive system and stays in the blood until it is decomposed by the liver or excreted with urine. The decline rate of alcohol concentration in blood is quite stable. In any case, no matter how long you are affected, as long as alcohol reaches a peak in your blood, it will be excreted from your body as long as alcohol leaves those affected people slower or faster than you. However, the rising speed of alcohol concentration in blood varies from case to case. Therefore, if you want to prevent the excessive increase of alcohol content in blood, you should think of the following factors when drinking. People with big bodies have more blood than people with small bodies. In the case of drinking the same amount, the alcohol concentration in the blood of people with large bodies rises slowly, and its total concentration is relatively low. Eating food in the stomach while drinking will slow down the speed at which alcohol is inhaled into the blood. If you eat while drinking (or eat some food before attending a social gathering), you can temporarily slow down the speed of alcohol absorption. Of course, you also eat more calories. Types and drinking speed of alcohol The slower you drink, the less intense the influence of alcohol. If you drink whiskey, a lot of alcohol will increase the alcohol concentration in your blood, which is much faster than drinking beer. If you take a swig of whisky, its alcohol will be quickly absorbed by your system. If you sip a glass of beer slowly, the alcohol in the beer may have dissipated by the time you finish it. The body's tolerance for frequent drinking will make you gradually "adapt" to the situation that there is a lot of alcohol in your blood, and your brain will "get used to" soaking in alcohol all day. As a result, if you have been drinking for many years, you may be able to drink normally and behave normally, but if you let someone who drinks less than you drink your blood, he will definitely show drunkenness. The appearance is unreliable. Alcoholics may speak neatly and clearly, but their driving ability will still be impaired and their brains and bodies will continue to suffer. The unfortunate consequence of increasing tolerance is that you must maintain the alcohol concentration in your blood. Moreover, you will gradually need more alcohol to achieve the effect of drinking. It is precisely because of this dependence that some people gradually degenerate into alcoholics (drinking addiction). Another thing to remember is that the alcohol content in the blood is accumulated over a period of time. Eating while drinking, eating food while drinking, and even eating snacks when attending social gatherings can slow down the speed of alcohol absorption, so that the amount of alcohol in the blood gradually increases, and its peak value is lower than that when drinking on an empty stomach. Excessive drinking has not only led to countless tragic events, but also seriously affected the image of individuals and even countries. Former Russian President Yeltsin is one of them. It is said that one day in September, 1994, Yeltsin, then Russian President, flew back to Moscow from Washington and was scheduled to have a 40-minute meeting with Irish Prime Minister Reynolds. The day before he left Washington, US President Bill Clinton hosted a banquet for him. Although there is no wine on the table, there is everything in it. Yeltsin only ate a small piece of meat, but raised his glasses frequently, and the cups bottomed out. After the wine reached the top, Yeltsin talked a lot, saying a lot of rude words and "three-level jokes." The translator racked his brains to "purify" the dirty words he said. When the plane approached the Shannon airport, Yeltsin woke up, and his wife handed him a shirt, but his buttoned hand never listened. The accompanying officials saw something bad. After some discussion, they decided to let the Deputy Prime Minister have a brief meeting with Reynolds on behalf of the President. When the Vice Premier got off the plane, Yeltsin said to the accompanying officials in tears, "What you did made me lose face in front of the whole world." . Minimize the harm of alcohol. "This wine looks like water. Eat spicy food in your mouth, be haunted in your stomach, walk stumbling, get up in the middle of the night to find water to drink, and wake up in the morning to regret it! " This is the truest portrayal of excessive drinking. However, when drinking is inevitable, how can people minimize the harm of alcohol to their health? You can't ignore the preparation before drinking. Professor Qu Yao believes that there are two aspects to the preparation before drinking: "First, choose the best drink. Second, eat something before drinking. What are the countermeasures for the only son to be lucky enough to drink? It's no use trying to persuade him or criticize him. Parents say that "wine can promote blood circulation", "keep out cold and strengthen bones" and "nothing can be done without wine", which is really irritating. On one occasion, he even got drunk and was taken to the hospital. However, he is only 15 years old! What should I do? A: Like the problem of adolescent smoking mentioned by the last parent, adolescent alcoholism is also a worrying social problem. The harm of smoking has long been publicized, so parents and teachers forbid students to smoke. But people's understanding of alcohol is one-sided. Many people only see the benefits of drinking, but ignore the harm of drinking. Therefore, the consumption of alcohol is increasing, and the phenomenon of teenagers drinking alcohol is also increasing. Statistics show that adolescent alcoholism has become a serious social problem. A survey on the mental health of college and middle school students in Shaanxi Province shows that 82% of the students have a history of drinking, including 89% boys and 75% girls. Moreover, among these students who drink alcohol, 23% drink liquor with high alcohol content. So are other countries in the world. According to the US Census Bureau, in the United States, about 1/3 or more teenagers aged 12 to 17 often drink alcohol, while in a certain area of the former Soviet Union, 90% to 95% of teenagers under 18 are addicted to alcohol. There is no doubt that a small amount of drinking is harmless to the body, which can relax muscles and promote blood circulation, keep out the cold and strengthen bones. However, excessive or addictive drinking will seriously affect people's physical and mental health. Excessive drinking for a long time can easily lead to vitamin deficiency and malnutrition, accelerate the formation of atherosclerosis and hypertension, induce myocardial infarction and cerebral hemorrhage, and may also increase the incidence of cancers such as throat, mouth and esophagus. Excessive drinking without restraint will also lead to acute alcoholism and even endanger people's lives.
