Don't smoke, drink less and drink more tea.
Tobacco, alcohol and tea seem to be closely related to people's lives. For many people, if there is no tobacco, alcohol and tea, something is wrong. Especially for some decent banquets, there must be good cigarettes, good wine and high-grade tea, otherwise there will be no banquet. Banquet is like this, even if guests come at home, they can't do without cigarettes, wine and tea. Usually, even if we don't have guests, people seem to be inseparable from cigarettes, wine and tea, which are really important contents in life. Because tobacco, wine and tea are closely related to people's health, it is necessary to study tobacco, wine and tea when it comes to health preservation.
-No smoking.
-Drink less.
-Drink more tea
First of all, it's best not to smoke.
Smoking is harmful to human health. However, in recent years, there are more and more smokers in China, not only middle-aged people, but also young people. Some eight or nine-year-old children are also learning to smoke, and female smokers are also developing rapidly. Although life is the most precious thing for people, smoking is equal to chronic suicide, but for smokers, it seems to be deaf, and you can't live without smoking. So, be sure to drink loudly: for your health and the prosperity of the country, it is best not to smoke! So, how can we not smoke?
(1) It is necessary to realize the harmfulness of smoking.
Some people have done some statistics: 90% of lung cancer, 75% of emphysema and 25% of coronary heart disease are all caused by smoking. About 2.5 million people worldwide die of various diseases caused by smoking every year, with an average of 1 person dying every 13 seconds. The number of deaths caused by passive smoking is 4000 ~ 5000 in the United States, 1000 in Britain and 500 in Canada each year.
1 cigarette contains nicotine that can kill 1 mouse, and 20 cigarettes contain nicotine that can kill people.
The countries with the highest male smoking rate in the world are all developing countries, such as Bangladesh, China, Indonesia, Morocco, Nepal and Thailand. More than 70% of men in these countries smoke. The countries with the lowest male smoking rate are all developed countries, such as Austria, Germany, Finland, New Zealand, Norway, Sweden and the United States. Less than 40% of men in these countries smoke.
If a smoker smokes a pack of low-grade cigarettes at 70 cents a day, the annual living cost is 255 yuan. If you smoke between the ages of 20 and 60, 10220 yuan will become a cigarette. If you deposit 2 1 yuan with interest in the bank, you will eventually become a million-dollar account.
All the above statistics show that people must not be insensitive to quitting smoking, and must make up their minds to quit smoking. But for many people, why can't they make up their minds? There are naturally many reasons for this. Smoke does have an irreplaceable role. A cigarette shop has a couplet that says, "I'm drunk, so I have to turn off the wine, and the guest can serve tea instead." Explain that cigarettes are convenient and pleasant. Smoking can also relax people's nerves, and conversation can ease the atmosphere. In movies, TV plays and literary works, most great men, celebrities and protagonists smoke, and there are many smokers in their lives, which undoubtedly gives psychological support and influence to smokers who want to learn. In fact, as long as people really understand the harm of smoking, or are forced by health reasons, smoking can also be quit. Many celebrities in history and real life can make up their minds to quit smoking. Here are just a few examples.
Gan Long likes smoking very much. He smokes almost whenever he has time. Later, I often coughed and sought medical advice too much. Cure too much: "The emperor coughs, because smoking hurts his lungs. If you want to cure it, you must give up smoking first. " Gan Long followed the doctor's advice, gave up smoking and cured his cough.
Marx used to be a heavy smoker and often smoked while working. He once said that the manuscript fee of Das Kapital was not enough to pay for the cigars I needed to write. Later, he got bronchitis, and the doctor forbade him to smoke, so he made up his mind to give up smoking.
In the past, former US President Ronald Reagan smoked a pipe. Because of 1985, he thought smoking was very dangerous to his health and decided to give up smoking. 1988, he signed a bill stipulating that cigarette box advertisements should contain more warnings about the dangers of smoking. The United States is striving to establish a "smoke-free" society by the year 2000.
The above shows that smoking can be quit as long as you make up your mind.
(2) Take measures to quit smoking according to different situations.
Tobacco is not addiction and morbid dependence, but a habit or conditioned reflex formed in long-term life, which is a mental and psychological reaction. Some people, when they first quit smoking, may have a sense of loss, a little fidgety, some slightly depressed, and increased saliva, which is mainly a manifestation of conditioned reflex, and it will pass in a few days.
Nowadays, more and more teenagers have developed the habit of smoking. According to statistics, at least 1/3 15 ~ 25-year-old young people in large and medium-sized cities smoke, and even some young women have started smoking. How to persuade them to quit smoking? The key is to persuade them patiently according to their state of mind. Some people smoke out of curiosity, mostly middle school students. They have a strong sense of adulthood and long for adulthood, which is one of them. The second is vanity, which is common in young workers around the age of 20. They think they don't smoke and are afraid of being laughed at as unsociable. In order to be "rich", they have to use "peony" and "Hilton" to put on a facade. The third is fashion sense, mostly young women. They think it seems fashionable to put a thin and long cigarette under their red nails. Young people who don't smoke for a long time are easier to give up. As long as you persuade patiently and guide correctly, most people will quit.
For the average person, to quit smoking, you should be prepared to go through five stages:
First, hard work and fatigue, that is, when you feel tired or use your brain to write materials, never forgive yourself, and take smoking as a comfort or stimulant in an attempt to relieve fatigue through smoking.
Second, on holidays, or to participate in festive activities, or to entertain long-lost friends and distant guests, smoking is no exception to celebrate.
The third is the relationship between emotions. Whenever there is a wedding, funeral or celebration, or you are depressed and worried, or you see any good cigarettes, you should not have an accidental psychology. Have another cigarette.
The fourth is self-esteem. Friends often regard quitting smoking as a joke. Some people say that quitting smoking is to save money, while others say that quitting smoking is because of "tracheitis" (henpecked wife). Often after a friend's "will", "self-esteem" rises in anger, so all previous efforts are in vain.
The fifth is the "final" level. People who quit smoking often comfort themselves, this is the last time, and there will be no more. Finally, there is the last one, one after another. As long as you can't pass one of the above levels, it will revive, and all previous efforts will be in vain, so you must not give up smoking lightly.
There are several situations that need special attention for smokers. Quitting smoking might as well start from these situations.
Avoid smoking immediately after meals. Many people often say: "A cigarette after a meal is better than a living fairy", which is all wet. Due to the vigorous metabolism of the human body after meals, many organs are in the best state of absorbing substances. If you smoke a cigarette immediately after a meal, the toxic dose is even greater than the usual 10 cigarette.
Second, avoid smoking after taking medicine. Because smoking will reduce the efficacy of drugs, this is because drugs in the human body are metabolized by the liver by oral administration or injection, and smoking will increase the activity of drug metabolizing enzymes in the liver and reduce the concentration of drugs. A hospital in new york, USA, also found that after taking some drugs for half an hour, the active ingredient in the blood is only 1.2% ~ 1.8%, while that of non-smokers is 2 1% ~ 24%, which is about 20 times of the former.
Third, avoid drinking and smoking. Because the carcinogens contained in the smoke at the inhalation port are deposited in the mouth, nose, throat, lungs and other parts of the smoker, when drinking is accompanied by smoking, the smoke oil attached to the mouth and throat will be inhaled with the wine, then quickly dissolved and absorbed by the blood. Because alcohol is metabolized by the liver, and the liver decomposes alcohol, it is impossible to eliminate tobacco poison in time, which makes the harm of tobacco poison to human health double.
Fourth, avoid smoking when going to the toilet. The ammonia concentration in the toilet is high and the oxygen content is insufficient. However, under the condition of hypoxia, tobacco will produce more sulfur dioxide and carbon monoxide due to incomplete combustion, so more harmful gases will be inhaled into the body, which is easy to induce angina pectoris in patients with coronary heart disease and acute attack in patients with tracheitis.
Fifth, avoid smoking in pregnant women and in the presence. After a woman is pregnant, if she smells smoke for a long time, she will have a miscarriage or premature birth; Children living in passive smoking environment for a long time will cause lung function decline and respiratory diseases.
Second, how to drink?
For thousands of years, people have forged a profound friendship with wine, which is a symbol of friendship and victory. Emotions and sorrows all need wine, so, "wine meets a thousand cups of friends" and "leisure is like snow, and it melts when you enter the wine", all over the world. Until today, wine is still a "friend" that people can't live without. As the saying goes: "No wine, no table." When entertaining friends and relatives during the Chinese New Year, selling wine and chatting happily can increase the atmosphere of friendship and joy.
Liquor is a beverage made of various grains, distillers' yeast or fruits, which can be divided into distilled liquor (soju, white wine) and non-distilled liquor (yellow wine, wine), both of which contain alcohol (ethanol).
Liquor: The main components are alcohol and water. Alcohol is not only a condiment and stimulant, but also a nutrient. Animal experiments show that 70% of the chemical energy of alcohol (ethanol) can be used by human body, that is, 1 g of ethanol can supply 5 kilocalories of heat energy.
Wine: Besides alcohol and water (about 89% ~ 90%), it also contains a lot of sugar, glycerol, protein, organic acids, organic salts and minerals. Wine is slightly sour, close to the acidity of human gastric juice (pH 2 ~ 2.5), and it is the best table drink for eggs. Wine is rich in vitamin B, but lacks vitamin C; Potassium and magnesium salts are also rich, but phosphoric acid and calcium are less.
Beer: It is a low-alcohol fermented wine, which can supply 400 kilocalories per liter of beer, half of which comes from alcohol and the other half from various sugars. Beer can stimulate insulin secretion and carbohydrate metabolism, and contains a lot of B vitamins, especially vitamin B 12.
Yellow rice wine: It is the most common low-alcohol beverage in China. It can not only remove fishy smell, but also be used as medicine to introduce menstruation, so it is deeply loved by people. Yellow rice wine can remove the fishy smell and smell of fish and shrimp. The odor of fish and shrimp is trimethylamine, which can be dissolved in the alcohol of yellow rice wine. When cooking, the fishy smell will evaporate with alcohol. Compendium of Materia Medica says: All kinds of wines are different, but rice wine is used as medicine. The so-called medicinal use refers to the use as a drug primer in Chinese medicine.
Medicinal liquor: This refers to the liquor made by adding a certain amount of certain foods and drugs into the liquor, which is used for disease prevention and fitness. Such as ginseng wine, can cure neurasthenia, fatigue, palpitation, shortness of breath, impotence and other symptoms; Hawthorn wine, treating overwork, physical fatigue and women's dysmenorrhea; Chinese wolfberry wine can treat eye diseases such as blurred vision, decreased vision and tears in the wind caused by liver and kidney deficiency, and can grow muscles and benefit complexion; Carthamus tinctorius wine for treating women's blood deficiency and blood stasis dysmenorrhea; Atractylodes macrocephala wine can strengthen teeth, make face shiny and prolong life.
People have different opinions about wine, and this phenomenon has probably not changed much since ancient times. In fact, wine can be a success or a bad thing. "Li Bai was drunk and wrote a pretty book" in Ancient and Modern Wonders tells that Li Bai concentrated his passion on the pen after drinking a lot, and wrote a book with great enthusiasm, which greatly boosted the prestige of the country. Li Bai is an alcoholic. Only by drinking can poetry flourish, so there is a much-told story of "One Hundred Poems of Li Bai Fighting for Wine". In the Water Margin, Song Wu was drunk and beat the tiger, and he was brave. Cao Cao and Liu Bei's "Heroes in Cooking Wine in Childhood" and Zhao Kuangyin's "Drinking to Relieve Soldiers" have all written articles on wine. But wine can also fail, for example, the collapse of Yin is related to the "wine pool meat forest"; The wailing of Emperor Yang Di was also related to "debauchery". Zhang Fei, a fierce man who shouted when the bridge broke and the water flowed backwards, was also drunk and hit people at random, and his head was cut off in a daze. Even in the 1990s, there were many tragedies of drinking to death.
Since wine has duality to human body, how to drink it is good for health?
First of all, drink less, not more. Because a small amount of drinking can make people refreshed, happy and relieve negative emotions. After a cold or at the beginning of a cold, a small amount of drinking can also prevent the occurrence and development of a cold. "Great cold congeals the sea, wine is not ice", which shows that wine is hot, can warm blood vessels, dispel wind and overcome cold. It has become a habit to drink two sips of white wine before breaking the ice into the water in winter. Lin Chong guarded the forage field on a snowy night, so he went to buy wine to drink when it was too cold. Drinking yellow wine and brown sugar after delivery can promote blood circulation, remove blood stasis and remove lochia. Therefore, wine is a medicine with a long history, which can not only relax muscles and promote blood circulation, dispel cold and dispel wind, but also make people excited and unrestrained. "Grape wine luminous cup, want to drink pipa immediately rush. Drunk in the battlefield, you don't laugh, and you have fought several wars in ancient times. " How magnificent! The above shows that drinking less is good for people. But it is not advisable to drink too much, because drinking too much often leads to acute poisoning. According to research, the amount of alcohol causing poisoning symptoms is about 75 ~ 80 grams, which is closely related to the alcohol concentration in human blood. Because the cerebral cortex of the higher nervous system is suppressed, the lower nervous center is out of control, which is characterized by being cheerful, eloquent and endless, and its discrimination, attention, memory and insight become dull, and the efficiency of doing things is greatly reduced. In severe cases, it further develops into depression and paralysis of the central nervous system, which often leads to deep sleep, lethargy and other symptoms, even life-threatening. According to clinical observation, people who are unconscious for more than 12 hours due to excessive drinking have the greatest risk of death. So, how much wine to drink is the right amount? If you drink less, you will get drunk when you touch alcohol; A heavy drinker won't drink three bowls in disorder. Everyone should decide according to their own actual situation, so as to feel warm and refreshed. Or just drink 1/5 of your capacity. If you have more than you can chew, you will be in a daze and your tongue will be weak, which is actually harmful to your health.
Secondly, drink slowly while drinking, and talk while drinking; Don't "drink it all at once", or even drink hard liquor. You can drink some strong tea at any time in the middle of drinking, which has the effect of hangover. Yokoyama Taikan, a famous Japanese painter in his 90s, reported that eating bean products such as tofu and bean sprouts while drinking is a good way to drink without affecting health. The report said: legumes are rich in vitamin B 1 and cysteine, and are the best anti-alcoholism drugs in the world.
Also, drink at the right time. As the saying goes, "wine is easy to get drunk when hungry", which means that people can't drink on an empty stomach, because "alcohol is absorbed quickly in the intestine, especially on an empty stomach before meals, and the blood drug concentration can reach a peak after 10 ~ 30 minutes" (see Wang's Science of Traditional Chinese Medicine). So, when will it be ready? Usually, when eating, drink slowly, just right.
And pay attention to the taboo after drinking. It is forbidden to "enter the house drunk". This means that after drinking too much wine, sexual intercourse is forbidden. Because it is difficult to control sexual behavior after drinking, we must try our best to be quick, which will seriously consume the most precious substance in the human body-yang essence, and sexual intercourse after drinking will affect the health of the next generation, "making children epileptic." It is forbidden to drink and drive. Although it mainly refers to drivers, with the improvement of people's living standards, all kinds of motor vehicles will enter thousands of households, so this article is also very important. Three prohibitions: "Don't make a hullabaloo about and get angry, don't trespass, … make people's internal organs upside down, don't cut them off, and don't kill people". It means don't get emotional after drinking, don't shout, don't get angry, and don't engage in strenuous sports such as running cars and walking horses. If you are excited again, it will easily lead to liver floating and gallbladder crossing, liver wind moving internally and a stroke.
Finally, pay attention to how to sober up after getting drunk. For those who are slightly drunk, vague in speech and rude, they should be advised to give up drinking immediately and let them drink strong tea or white radish juice to sober up. On the one hand, let the moderate drunkard with unstable gait and moody rest quietly, on the other hand, use vinegar and sugar to sober him up. The method is: add 15g white sugar and a little boiled water into 30 ml vinegar, dissolve the white sugar and take it once; 60 grams of black beans or 30 grams of lentils can also be decocted in water; You can also drink light salt water soup often. If a drunken person vomits repeatedly, you can put a piece of ginger under his tongue to stop vomiting. Those who are unconscious and seriously drunk should be sent to the hospital for emergency treatment immediately.
Third, we must insist on drinking tea.
Tea has always been regarded as a product to prolong life and has the effect of "panacea". Su Dongpo, a famous poet in the Song Dynasty, argued that people who have minor illnesses only need to drink tea instead of taking medicine. A poem said, "Why did Di Wei take a pill and drink seven bowls of tea?" Lu Tong was a famous scholar in Tang Dynasty, who was famous for drinking tea in history. In his poem "Xie Meng Suggests Sending New Tea", he vividly described the beauty of drinking tea: "One bowl moistens the throat, two bowls are lonely and boring, and three bowls are poor, but there are only 5,000 volumes of words; Four bowls of light sweat, uneven life, all pores scattered; Five bowls of bones and muscles are clear, six bowls of fairy gas pass, and seven bowls can't be eaten, but I feel gently blowing on both sides. " This is the world-famous "Seven Bowls of Tea in Lu Tong".
China is the country with the most premature tea in the world and the hometown of tea. In Tang Dynasty, Lu Yu wrote the world's first tea masterpiece "Tea Classic", and discussed the origin, varieties, planting techniques, processing methods, cooking methods, drinking methods and various utensils related to cooking and drinking. This monograph on tea science and technology has spread the knowledge of tea, which is not only a great contribution to the development of tea in China, but also has a far-reaching impact on the development of tea in the world. The export of tea in China has gradually promoted the development of tea drinking in the world, making tea one of the three major drinks in the world. Why is tea so popular? This is mainly due to the health care function of tea.
Tea not only has good curative effect, but also has many functions, which can prevent and treat many diseases. As early as the Tang Dynasty, the medical scientist Chen Zangqi saw this point and put forward that "all kinds of medicines are the medicine for all diseases, and tea is the medicine for all diseases", and spoke highly of the health care function of tea. Specifically, he said, the main functions of tea are:
(1) refresh your mind. "The north window snores like thunder, who will send the grass for a dream?" This is an elegant sentence in Lu You's poem "Try Tea", which shows that tea has refreshing effect. Even Bai Juyi, a great poet in the Tang Dynasty, praised the refreshing effect of tea with the poem "See tea after sleeping". Tea is refreshing because it contains caffeine that can excite the central nervous system.
(2) diuresis strengthens the heart. As the saying goes, "tea is too thick to pee." After three drinks, one is easy. "This refers to the diuretic effect of tea, so drinking tea can treat a variety of urinary system diseases, such as edema, cystitis, urethritis, etc.; For urinary calculi, tea also has a certain stone-discharging effect. Fujian Medical University conducted a survey of 1080 people in Anxi tea area, and found that drinking tea is closely related to reducing the occurrence of coronary heart disease. The incidence of coronary heart disease was 3. 1% in people who didn't drink tea, 2.3% in people who drank tea occasionally and 1.4% in people who drank tea frequently. It can be seen that drinking tea often is really good for preventing coronary heart disease. This is because caffeine and theophylline contained in tea can directly excite the heart, dilate the coronary artery, make blood fully input into the heart, and improve the function of the heart itself.
(3) promoting fluid production to quench thirst. Compendium of Materia Medica says: "Tea tastes bitter and cold, and ... can reduce fire best. Fire is a hundred diseases, and fire must be clear. " The Compendium of Materia Medica of the Tang Dynasty also said: "It is expensive to quench thirst and eliminate epidemic diseases." Especially in summer, tea is a good drink for heatstroke prevention and cooling.
(4) Xiaoshi Jiejiu. Drinking tea can get rid of greasy and help digestion. Eating meat with vegetables on holidays and making a cup of strong tea is easy to indigestion. This is because tea contains some aromatic compounds, which can dissolve fat and help digest meat. Some meat-based ethnic minorities in the border areas of China are well aware of this. They said, "A day without oil and salt is better than a day without tea." The reason why tea can relieve alcoholism is that caffeine in tea can improve the metabolism of substances in the liver, enhance blood circulation, help the alcohol in the blood to be excreted, and reduce and eliminate the stimulation caused by alcohol. Therefore, a good cup of tea after drinking will help sober up and relieve alcoholism.
(5) sterilization and anti-inflammation. Experiments show that tea can inhibit Escherichia coli, staphylococcus and virus, because polyphenols such as catechin and theaflavin in tea can bind with virus protein, thus reducing the activity of virus. Tea extract or decoction has antibacterial effect on all kinds of Shigella dysenteriae, and its antibacterial effect is equivalent to that of Coptis chinensis.
(6) Lowering blood pressure and resisting aging. Tea polyphenols, vitamin C and vitamin PP are all effective components in tea, which can reduce blood fat, blood pressure and improve vascular function. According to "Foreign Tea Trends", there are 80 hypertensive patients, and 50 patients can return to normal blood pressure within 5 days after drinking tea. It is generally believed that green tea is better than black tea in lowering blood pressure. The anti-aging effect of tea is the result of the comprehensive action of vitamin E and various amino acids contained in tea. In Japan, it is said that "tea ceremony" people live long, have good complexion and moist skin, which has a lot to do with their frequent drinking of tea. Therefore, some people in Japan call "tea is a fairy medicine".
In addition to the above functions, tea has many health care and medical functions. Therefore, drinking tea often is good for health. But we must also pay attention to methods and know how to drink tea scientifically. The specific method is as follows:
First of all, we should choose different kinds of tea and drink it in different ways according to different physique, age, work nature and living environment. Physically, healthy adults can drink red and green tea; For the elderly, it is advisable to drink black tea. You can drink a cup of green tea or scented tea indirectly, but the tea soup should not be too strong. For women and children, light green tea is generally suitable, and children can also advocate gargling with tea in the morning. Girls are irritable before and after menstruation, and drinking scented tea can soothe the liver and relieve depression, regulate qi and regulate menstruation; For menopausal women, drinking scented tea is also desirable. Drinking green tea properly during pregnancy is beneficial, because green tea contains more trace element zinc; Women should drink black tea before delivery, such as adding brown sugar. Patients with gastropathy or duodenal ulcer should drink black tea instead of strong tea. People with habitual constipation should drink light black tea. People with poor sleep should drink light tea at ordinary times, and be careful not to drink tea before going to bed. For patients with coronary heart disease with bradycardia or sinus block, drink more red and green tea to increase heart rate. People with enlarged prostate should drink scented tea. Patients should drink high-grade green tea after operation to facilitate wound healing. From the nature of work, manual workers, soldiers, geological prospectors, and people who are often exposed to radiation and toxic substances should drink some strong tea; Mental workers should also drink some advanced green tea to help them think.
Secondly, we should pay attention to the water used for making tea. Spring water is sweet and delicious, so spring water is the best water for drinking tea. Spring water is the best way to make tea, so the river is not beautiful. Bai Juyi, a great poet, once wrote a poem praising Jiang Shui for cooking tea. The poem says, "Shu tea is wonderful, Wei water is fried and precious." However, river water is easy to be polluted near towns and industrial and mining areas, so it is best to draw clean water from places far away from towns and industrial and mining areas. In addition, well water can also be used to make tea, and the water quality of some well water is also very good. However, well water is generally hard water, because there are more dissolved substances and higher hardness in the laminar flow. Moreover, the well water is dark in color, less in contact with air, less in dissolved oxygen and carbon dioxide gas, and the tea is not fresh enough. Therefore, Cha Sheng Lu Yu said that making tea from well water is the next step. Pond water, which is small but not flowing, is difficult to purify itself after pollution, and the water quality is often poor, so it is the most unsuitable for making tea.
Also, choose a good tea set. There are many kinds of tea sets in common use, each with its own characteristics, but the best is the purple sand teapot in Yixing, Jiangsu, and the white porcelain or porcelain teacup in Jingdezhen, Jiangxi. In different tea sets, even if the same quality of tea leaves and water are put in, the brewed tea will have different colors, smells and tastes.
And pay attention to scientific brewing methods. It is best to make tea in a teapot, and then pour the tea soup into a teacup, which is not only conducive to the preservation of tea fragrance, but also saves tea. Making tea directly with a teacup is easy to make the tea fragrance disappear, and the tea soup is bitter first and then weak, which affects the effect of drinking tea. Drink ordinary red green tea, each cup of about 3 grams of tea, 200 ml of boiling water for three to five minutes, you can drink. But some famous teas have specific brewing methods, such as Fujian oolong tea. After the first brewing, you should continue to drink. The second brewing time is a little longer, about one minute, and then it will be extended with the brewing times, but not too long.
Although tea is extremely beneficial to the human body, it is not "without any harm". If you drink tea too much or improperly, it will often bring many bad consequences. For example, theophylline and tannic acid in tea can stimulate gastrointestinal tract. Drinking strong tea, especially on an empty stomach, can cause stomach discomfort and stomachache, and induce and aggravate gastric or duodenal ulcer. Tannic acid in tea has astringent effect, and studies have found that many young people's serious constipation is related to drinking too much tea. In addition, drinking too much tea can lead to anemia. Tea is a common drink for infants in Israel, where the incidence of iron deficiency anemia is as high as 26% ~ 68%. This is because tannic acid in tea can form insoluble ferric citrate with iron in intestine, which cannot be absorbed and utilized by human body. Because the absorption of iron is affected, the storage of iron is reduced, and anemia occurs over time. Some people like to drink tea and take medicine, which is also wrong. Tea can't be drunk with baking soda, sleeping pills, quinine, iron and other drugs at the same time, because tea contains a lot of tannic acid, which can react with protein, alkaloids, metal salts and so on in drugs, resulting in precipitation, which affects the curative effect of drugs and even fails. It should also be pointed out that not drinking a lot of strong tea before going to bed will cause insomnia, even taking sedatives will not help.
Tea has a long history as a drink for people to eat, but it is a recent thing to use it as a tea bath. Tea bath is actually a kind of medicinal bath. The effective components of various tea leaves dissolved in bath water enter the body through the absorption of skin capillaries, and some effective components of tea leaves can evaporate with steam, enter the body through respiratory tract, and play a synergistic role in tea bath. Modern medical research believes that taking a bath with tea is good for health. Because tea contains tannic acid, caffeine and aromatic oil, it helps to remove dirt and body odor, make people feel refreshed after bathing and eliminate fatigue. Tea also contains tannic acid and lipopolysaccharide. People who often watch TV or work in the scorching sun for a long time often take a bath with tea, which helps to prevent the damage of light radiation to the skin.
