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. Before and after menstruation, girls are irritable, 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. 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.
