Small tea ceremony university asked.
When talking about drinking tea after drinking, Lingqian Kong, an expert in health care of traditional Chinese medicine, also said: Some people like to drink a large cup of strong tea to sober up when they are drunk, which does have a certain sober-up effect, but drinking tea after drinking is also very harmful.
Because drinking stimulates the heart, the heart beats faster and the brain is excited, strong tea also has the same effect. Drinking drunk tea is simply adding fuel to the fire.
After drinking, alcohol directly enters the blood after entering the stomach, then enters the liver and is converted into acetaldehyde, then into acetic acid, and finally into carbon dioxide and water, which is excreted through the kidney. Carbon dioxide and water are normal metabolites and have no harm to the kidneys, while drinking strong tea to sober up skips this step. Theophylline in tea has diuretic effect, which can make acetaldehyde in human body excrete directly through the kidney, thus playing a role in quickly sobering up. Acetaldehyde is harmful to the kidneys, and drinking strong tea often after drinking will cause renal insufficiency.
Therefore, it is best to drink some hangover soup. Of course, not drinking too much is the fundamental solution.

If you drink the right tea, you will stay healthy. If you drink the wrong tea, it will hurt your health and get wet.
Tea is a national drink. In the world, when it comes to China, one thing that must be mentioned is tea. Tea is not only a drink, but also a means of health preservation. Legend has it that Shennong tasted all kinds of poisons every day, and the poison broke out on the ground. At this time, there happened to be a small tree beside him, and the leaves were fragrant. He ate a few leaves and the toxicity was reduced. This little tree is a tea tree. Therefore, since ancient times, there has been a saying that "tea can cure all poisons".
I have a friend who likes drinking tea very much. After retirement, he has time, especially after he has read many books about how to keep tea healthy. However, after drinking for a period of time, not only do other tea lovers feel healthy and refreshed, but they often feel uncomfortable. What is the reason? Is it because your constitution is not suitable for drinking tea? It turns out that his favorite teas are Longjing and Tieguanyin, and they are very heavy and strong. Longjing is green tea and Tieguanyin is oolong tea, both of which are cool. If you drink these two kinds of strong tea often, especially the elderly, it will hurt your spleen and it will naturally get wet.
So, how to drink tea is healthy?
One is divided into seasons:
You can drink a little green tea and oolong tea in spring and summer, which can clear away heat and relieve summer heat. It is suitable to drink a little black tea or Pu 'er tea in autumn and winter, which is warm and can drive away the cold.
The second is to divide the time:
Drink a cup of light green tea in the morning to refresh your mind;
Drinking jasmine tea in the morning has a pleasant fragrance and can improve work efficiency;
Drink a cup of black tea in the afternoon to get rid of difficulties and refresh yourself;
Getting together with friends or family at night and making a pot of oolong or Pu 'er will not affect sleep.
We might as well try this arrangement of drinking tea some day.
Third, by age:
Especially for the elderly, you can drink more black tea and Pu 'er tea and less green tea and oolong tea, especially oolong tea, because its tea soup is strong, so you should pay attention to drinking less.
The fourth is proper brewing:
The longest time for washing tea is 15 seconds. "Now everyone likes to wash tea when drinking tea, but I don't approve of excessive washing tea." Han Chi said that we found in the experiment that the leaching rate of effective components in green tea was over 70% and that in black tea was over 60%. In other words, washing tea too much will lose a lot of nutrients.
Jiang Heyuan reminded that if tea leaves must be washed, the washing time should not exceed 15 seconds. Green tea and white tea, it is best not to wash. "But there is one exception. People who are sensitive to caffeine can wash it before drinking tea, because the caffeine in it is leached faster than tea polyphenols, and quick washing can remove some caffeine. "
It is best to brew according to the proportion recommended by books or tea artists, and the elderly can be slightly lighter, especially the new tea is colder, because the storage time of tea is too short, and there are more polyphenols, alcohols and aldehydes. Therefore, although new tea is fragrant, it should be light and not drinkable.
After choosing the right tea, how to make it play its greatest role is also a science. Han Chi said: "Different teas have different methods of preservation, brewing and drinking."
V. Preservation method:
Tea is most afraid of moisture and odor. Tin bottles, porcelain jars and colored glass bottles are the best containers for preservation. Secondly, we should use tin cans, wooden boxes and bamboo boxes. Plastic bags and cartons are the worst. The container should be dry, clean and free of peculiar smell. Well-preserved tea should be placed in a dry and ventilated place, not in a damp, high temperature, unclean or exposed place. There must be no irritating articles such as camphor, medicines, cosmetics, cigarettes and washing products in these places. The new green tea of that year can also be sealed and put into the freezer, which can be kept for 3-6 months.
Sixth, drink in moderation:
12g per day is the most suitable. Jiang Heyuan suggested that for ordinary people, it is appropriate to drink about 12 grams of tea every day and brew it three or four times.
People who eat more greasy food and have a large amount of alcohol and tobacco can appropriately increase the amount of tea.
Pregnant women and children, neurasthenia, tachycardia, should be appropriate to reduce the amount of tea.
Seventh, hot and cold should be appropriate:
Han Chi reminded that with the popularity of Kung Fu tea, people drink tea "more and more hot", which is very wrong. "People drink tea for health care, but drinking hot tea will increase the incidence of cancer such as esophageal cancer, which is not worth the candle.
The best temperature for drinking tea should be about 60 degrees, not more than 70 degrees. "
Drinking tea in life pays attention to light tea for health. Strong tea is harmful to health, and drinkers should pay great attention to it.
Tea has the functions of refreshing, promoting digestion and benefiting health, which is closely related to people's lives. However, if you drink too much tea, it will be harmful to your health. For the elderly, it is particularly important to pay attention to the concentration of tea to protect their health.
Old people should not drink more strong tea.
Generally speaking, the elderly who often drink a lot of strong tea are prone to a lot of physical discomfort, such as easy dilution of gastric juice and inability to digest normally. The normal gastric juice secreted by a person every day is 1.5-2.5 liters, which can reasonably digest the food that a person takes in every day. When drinking a lot of strong tea, it will dilute the gastric juice, reduce the concentration of gastric juice, make the gastric juice unable to digest food normally, and cause indigestion, abdominal distension, abdominal pain and other symptoms, and some even cause duodenal ulcer.
In addition, tea hinders the body's absorption of iron. Tea contains tannic acid, black tea contains about 5%, and green tea contains about 10%. When people drink a lot of strong tea, the combination of tannic acid and iron will be more active, which will bring obstacles and influence to the absorption of iron and cause iron deficiency anemia.
And drinking strong tea is easy to cause constipation. Tannic acid in tea can not only combine with iron, but also with protein in food, forming a large amount of tannic acid protein, which is difficult to digest and absorb, leading to constipation. For the elderly with constipation, constipation will be more serious.
Finally, strong tea can lead to high blood pressure and heart failure. Caffeine in strong tea can make the human heart beat faster, thus raising blood pressure; At the same time, a large amount of strong tea liquid enters the blood vessels, which can increase the burden on the heart, produce discomfort symptoms such as chest tightness and palpitation, and aggravate the degree of heart failure.
Everything is measured. Drinking light tea can keep you healthy, while drinking strong tea is harmful to your health. In order to prolong life and spend the rest of life safely, it is very important for the elderly to abandon "strong" and choose "light" when drinking tea.
Leftover tea can also exert residual heat.
It is no exaggeration to say that tea is full of treasures. As long as we make good use of it, "expired" tea can also exert its residual heat.
One is overnight tea.
Jiang Heyuan said that there is no harm in drinking overnight tea, but tea leaves are easily oxidized, so there are often refreshments on the cups of overnight tea. In addition, the temperature is high in summer, and tea leaves are easily contaminated by bacteria, moldy and rancid, leading to diarrhea, so it is best not to drink overnight tea in summer. If you don't want to pour it out, you can also use it for the following purposes: 1 Overnight tea is rich in acid and fluorine, which can not only prevent capillary bleeding, but also play a role in sterilization and anti-inflammation, such as oral bleeding and skin bleeding, and can be used for bathing and gargling; 2. Wash your hair with overnight tea to treat scalp itching; Bad breath annoys many people. If you gargle with overnight tea three times a day, you can eliminate the trouble of bad breath.
The second is old tea and tea residue.
Longjing and other green tea people pay attention to drinking the new tea of that year. If they don't finish it, these teas can also play a role:
1. Cook.
When stewing meat or cooking other greasy and fishy dishes, you can put some tea leaves, which can remove oil and greasy;
2. Tea dregs can be dried and put away, and made into tea pillows with old tea, especially suitable for summer use. If the amount of tea is not enough, you can also make a small tea bag and apply it to your eyes, which can alleviate visual fatigue;
3. After the soaked tea leaves are dried, they can be scattered in damp places at home, such as under the bed, which can absorb moisture.
