Don't drink green tea during menstruation. Drinking scented tea depends on personal physique medical guidance: It is the habit of many women to drink a cup of tea to refresh themselves after work, which is the vice director of Chen Xiaoping, Gynecology Department of Guangdong Second Hospital of Traditional Chinese Medicine. But if you are having your period, you should pay attention to the taboos. Dr. Chen Xiaoping reminded that women are in a special physiological state during menstruation. If they insist on drinking tea every day as always, it will lead to excessive loss of iron in the body, which will easily lead to anemia and aggravate constipation during menstruation. Therefore, it is suggested that women should try not to drink green tea during menstruation, and drink less black tea. Scented tea should also be carefully selected according to personal physique. Don't drink green tea and black tea during menstruation. Iron is an important substance for synthesizing hemoglobin. Under normal circumstances, iron in the human body is lost every day, and the loss of iron is more serious when women lose a lot of blood during menstruation. If you drink green tea at this time, it will aggravate the loss of iron and easily cause anemia. "Green tea contains more tannic acid, which combines with iron molecules in food to form a large number of precipitates, which hinders the body's absorption of iron molecules and aggravates the loss of iron." Dr Chen Xiaoping said. In addition, tannic acid in tea will aggravate menstrual constipation. "Women are prone to constipation during menstruation, and tannic acid will slow down intestinal peristalsis and make the stool stay in the intestine, thus aggravating constipation." Black tea has the functions of anti-inflammation, sterilization and detoxification, which can strengthen the stomach and help digestion. Compared with green tea, there is less tannic acid, so drinking it in moderation during menstruation will not have much impact on menstruation. However, because any tea contains tannic acid, although black tea does not contain as much as green tea, it will still increase the loss of iron. In addition, there is caffeine in all tea leaves. "It is easy to sleep when drinking tea at ordinary times. People who are sensitive to caffeine should never drink tea again during menstruation. Caffeine can stimulate nerve excitement and aggravate menstrual syndrome such as dysmenorrhea, headache, backache, breast pain and mental stress that are prone to occur in women's physiological period. " Dr Chen Xiaoping said. Don't drink rose tea for women with a large amount of menstruation. In recent years, scented tea has become more and more popular among women, such as rose tea, chrysanthemum tea and jasmine tea. "Because there are many kinds of scented tea, if you don't understand the characteristics and physical fitness of scented tea, drinking a certain scented tea for a long time or drinking scented tea during menstruation will also have certain side effects on your body." Dr Chen Xiaoping said. For example, rose tea, which many people like, can promote blood circulation, remove blood stasis and promote qi circulation, and has a certain effect on dysmenorrhea symptoms caused by abnormal blood circulation and blood stasis in uterus, but it is particularly inappropriate for people with a lot of menstrual blood. Chrysanthemum tea can clear away heat and detoxify, but it is not suitable for people with yang deficiency constitution to drink for a long time. Dr. Chen Xiaoping also reminded women who are prone to nervousness, insomnia, excessive menstruation or too little menstruation to eat out during menstruation and try not to drink too much soup. "
