Hello, after drinking, you will be anesthetized and drunk because alcohol invades the cerebral cortex. The chief culprit of vomiting and headache is acetaldehyde. Acetaldehyde formed by alcohol decomposition can stimulate autonomic nerves, dilate blood vessels or atrophy muscles, thus causing headaches. At the same time, the trace fusel oil contained in wine is also a factor that can lead to dizziness after drinking. How to avoid 1, don't drink on an empty stomach, because alcohol on an empty stomach absorbs quickly and people get drunk easily; Moreover, drinking on an empty stomach is harmful to the gastrointestinal tract, and it is easy to cause gastric bleeding and gastric ulcer. The best preventive method is to use edible food, such as fat and hoof, or drink milk, and protect the stomach by using the indigestible characteristics of fat in food to prevent alcohol from permeating the stomach wall. Don't drink on an empty stomach, this is the main trick not to get drunk. Because it can prolong the absorption time of ethanol in the body. 2. Don't drink with carbonated drinks such as cola and soda. The ingredients in this kind of drinks can accelerate the absorption of alcohol by the human body. As for drinking hot soup after drinking, especially fish soup stewed with shredded ginger, it has a special hangover effect. Because alcohol is harmful to the liver, you should eat more green leafy vegetables when drinking, in which antioxidants and vitamins can protect the liver. You can also eat some soy products, of which lecithin has the function of protecting the liver. There is no scientific basis for the popular saying of drinking strong tea to relieve alcoholism. Tea polyphenols in tea have a certain protective effect on the liver, but theophylline in strong tea can make blood vessels contract, raise blood pressure and aggravate headaches. Therefore, you can drink light tea after drunkenness, and it is best not to drink strong tea. If someone drinks too much involuntarily, they can eat some fruit or drink some juice afterwards, because the acidic components in fruit and juice can neutralize alcohol. Many people often don't eat after drinking, which is more harmful. They should eat some digestible food, such as a bowl of noodles. 6, should be slow rather than fast. Alcohol can enter the blood five minutes after drinking, and the alcohol concentration in the blood can reach the peak at 30- 120 minutes. If you drink fast, the concentration of ethanol in your blood will increase rapidly and you will get drunk soon. If you drink it slowly, your body can have enough time warp ethanol, and the amount of ethanol produced is less, so it is not easy to get drunk. 7. Combination of food and drink. When drinking, the best thing to eat is pork liver. This is not only because of its rich nutrition, but also because pig liver can improve the detoxification ability of human body to ethanol. People who drink regularly will lose vitamin B in their bodies, and pig liver is the most abundant food of vitamin B, so it is an ideal match to eat boiled pig liver or fried pig liver. 8. Fruit dessert. Eating dessert and fruit immediately after drinking can prevent getting drunk. As the saying goes, "If you eat sweet persimmons after drinking, the smell of wine will disappear", which is true. Sweet persimmon and other fruits contain a lot of fructose, which can oxidize ethanol and accelerate the decomposition and metabolism of ethanol. Dessert has a similar effect. 9. To prevent gastritis and dehydration after drinking, you can drink milk with sugar or honey, which can promote the decomposition of ethanol and protect the gastric mucosa. Because dehydration will cause salt loss, you can drink some light salt water or rehydration salt. 10, hangover countermeasures. The so-called hangover refers to excessive drinking, which leads to headache and stomach upset the next morning. This is because after drinking a lot of alcohol, liver cells can't handle all the harmful substances acetaldehyde, which causes acute poisoning symptoms. When you have a hangover, the liver will accumulate fat, and the gastrointestinal tract is prone to alcoholic acute gastritis. The imbalance of autonomic nerve leads to the acceleration of heartbeat, and the imbalance of water and electrolyte in blood affects the whole body. It is best to use "sleep rest" to solve this problem. Adequate rest can help you recover quickly. Taking a hot bath after drinking can promote blood circulation, help metabolism and make alcohol excreted with sweat. However, patients with hypertension and cardiovascular diseases should be careful of stroke after drinking and taking a bath, and should take a short rest first. Alcohol dehydrates cells in the body. Replenish a lot of water before going to bed and then after waking up, which will help alleviate the discomfort caused by dehydration. Drink more fruit juice or honey lemon juice, which not only supplements water, but also contains fructose, which can accelerate alcohol metabolism and slow down nausea. Eating a balanced dinner can supplement all kinds of lost essential nutrients; But the diet should be light, and don't eat fried or high-fat food. 1 1.
