But tea can't be drunk every time, especially female friends should pay special attention to avoid getting worse! The periods when female friends are not suitable for drinking tea are divided into:
1, every month when the physiological period comes. Because menstrual blood will consume a lot of iron in the body at this time, female friends should add more vegetables and fruits rich in iron, such as spinach, grapes and apples. However, if you are used to drinking tea when you are full, this kind of tea contains as much as 50% tannic acid, which will hinder the absorption of iron by our intestinal mucosa and greatly reduce the absorption of iron, so it is easy to precipitate iron in the intestine and chyme or iron stone in blood-enriching drugs.
2. Pregnant women are not suitable for drinking tea during pregnancy. Generally, the concentration of caffeine contained in strong tea is as high as 10%, which will increase the times and frequency of urination and heartbeat of pregnant women, increase the load on their hearts and kidneys, and more easily lead to pregnancy poisoning, so it is better to drink less tea.
Pregnant women should not drink too much tea before giving birth. If you drink too much strong tea before giving birth, the caffeine in the tea will have an exciting effect and lead to insomnia. If pregnant women don't get enough sleep before delivery, it may lead to exhaustion and even dystocia during delivery. This is a big rule!
Mothers who want to breastfeed themselves just after giving birth should not drink too much tea. Because if you drink a lot of tea during this period, the high concentration of tannic acid in tea will be absorbed by mucosa, which will affect the blood circulation of breast and inhibit milk secretion, resulting in insufficient milk secretion.
5. After the mother drinks the tea, the caffeine in the tea will penetrate into the milk, which will indirectly affect the baby and be harmful to the baby's health.
6. In addition to dizziness and fatigue, menopausal women sometimes have an accelerated heartbeat, which leads to bad temper and poor sleep quality. If they drink too much tea, these symptoms will get worse. Therefore, if people who like drinking tea are at these special stages, it is best to stop so as not to spoil their health.
