Precautions for drinking tea:
1: Pregnant women should not drink tea.
Pregnant expectant mothers usually pay great attention to their diet. They can't eat this and that, but they don't pay attention to tea, a very common drink. Because theophylline contained in tea has an exciting effect, it has a certain influence on the formation and development of the fetus. Moreover, most of the tea leaves are cold, which is also very unfavorable to the development of the fetus, so special attention should be paid.
2. Don't drink tea during menstruation.
It is very cold in winter, and some women like to drink tea to keep warm. However, if they lose too much blood during menstruation, if they drink tea again, it will cause the loss of iron in the body and form iron deficiency anemia. At the same time, medical experts found that compared with people who don't drink tea, people who have tea habits are 2.4 times more likely to have menstrual tension, and those who drink more than 4 cups of tea a day are 3 times higher.
Old people drink less tea in winter.
Because tea itself is cold, the elderly's resistance drops in winter, and their hands and feet are prone to chills. If you drink a cup of tea at this time, it will only get colder and lead to the invasion of diseases. Therefore, it is better for the elderly to drink less tea in winter.

Black tea can warm the stomach, wake up, help digestion, but also relatively mild, you can use black tea instead of green tea. Also, if you must drink green tea, it is necessary to add some red dates. Because red dates are also warmer, they can help remove the cold of green tea.
