    Tea has a significant positive impact on human health, and can also help to treat and prevent a variety of diseases But there are also some taboos to be paid attention to when drinking tea Here are some situations that are not suitable for drinking tea Don't drink tea overnight: tea that has been soaked for a day not only doesn't taste good, but also may be harmful to health When tea is brewed with hot water, a large amount of protein and tannin will remain in the leaves After several hours or overnight, the tea leaves may decay or oxidize to produce strong irritants These stimulants stimulate the stomach and small intestine, which may cause inflammation of these organs Drinking tea when hungry: according to Chinese medicine, drinking tea on an empty stomach can cause "cold" in the lungs and stomach Therefore, it is not good to drink a lot of tea on an empty stomach Drinking tea when you are hungry may temporarily relieve your hunger, but it will not last Because of the conflict between the alkalinity of tea and the acidity of stomach, it is possible for people with sensitive stomach to drink tea when eating Drinking a lot of strong tea on an empty stomach will lead to a large amount of tannic acid entering the digestive organs, inhibit the secretion of gastric juice, and easily cause gastritis Tea reduces the absorption of iron, which will cause trouble for people with iron deficiency anemia In addition, it also reduces the absorption of vitamin B1 Tea before going to bed: tea contains a lot of caffeine Drinking too much tea after dinner can leave caffeine in the system for hours Caffeine can stimulate the central nervous system and cause insomnia Therefore, it is advisable to avoid drinking tea within 2 hours before going to bed Tea during pregnancy: if you plan or are already pregnant, you may be told to include enough folic acid in your diet Folic acid reduces the risk of neural tube defects in infants Green tea contains a chemical called catechin One of its functions is to inactivate the enzyme dihydrofolate reductase The role of dihydrofolate reductase is to help absorb folate Therefore, drinking tea while taking folic acid nutrition may cause folic acid to lose its beneficial effect Tea with medicine or fever: green tea can interfere with or interact with medicine Therefore, for safety reasons, avoid drinking tea for at least 2 hours after taking any medicine In addition, drinking tea has no cooling effect As a mild stimulant, green tea may further increase body temperature The body cools by sweating, but the tannins of tea actually inhibit this effect Drink too much tea: as with anything, too much is not good Many people think that tea can solve the problem of dehydration better than coffee But not more than six cups a day Why? Drinking too much tea can lead to excessive caffeine and minerals For most people, 3-6 cups is the most appropriate In addition to the above situation, drinking tea has a great positive impact on health in general I now drink 3-4 cups of green tea every day, which feels so good and energetic.
