What harm does drinking strong tea do to human body?
First of all, drinking strong tea will damage our stomach. The strong tea in our life contains a lot of caffeine and theophylline. If these contents are too high, the nerve center will be too excited. Today, gastrointestinal peristalsis will accelerate, gastric wall cells will secrete hyperfunction, and gastric acid will increase, causing gastric ulcer. These factors in strong tea sometimes endanger people's lives, so we must try to drink less or not to drink strong tea.
Secondly, strong tea affects sleep and damages heart health. Strong tea contains a lot of caffeine, which has a stimulating effect on people. Excessive drinking of strong tea will make a lot of caffeine stimulate people's nerve center, so people will be too excited and lose sleep. Drinking strong tea can also cause the heart to beat too fast, which is not good for patients with coronary heart disease with tachycardia, premature beats and atrial fibrillation.
Thirdly, drinking strong tea affects the absorption of nutrients in food. There are many tannins in strong tea, which can combine with protein, vitamin B 1 and iron ions in food, so that these nutrients can not be absorbed normally, which is easy to cause nutritional deficiency and produce corresponding symptoms, such as anemia and constipation.
Finally, some women in pregnancy, childbirth and lactation can't drink strong tea. Drinking strong tea will affect the healthy growth of the fetus. Women in menstrual period can't drink strong tea, because it is cool, and drinking strong tea will lead to dysmenorrhea.
Here, we would like to remind that women can't drink strong tea under some special circumstances, that is, pregnant women, women in labor and menstruation, and lactating women. Drinking strong tea in pregnant women will lead to increased fetal movement and fetal dysplasia, and drinking strong tea during childbirth will lead to delivery room failure and dystocia. Drinking strong tea during menstruation leads to excessive blood loss, which affects the absorption of iron, causes dysmenorrhea and prolongs menstruation. Drinking strong tea during lactation causes the baby to be excited and make the baby cry.
Strong tea is harmful, but you can drink less. Although strong tea has many hazards, we can also drink some strong tea in moderation. In some cases, drinking strong tea can clear away heat and detoxify, moisten the lungs and resolve phlegm, strengthen the heart and diuresis, sober up and help digestion. Some people in our life have damp-heat syndrome, drinking strong tea can alleviate it, and some people who drink too much can help sober up. People generally feel very greasy after a big fish and big meat dinner. Drinking strong tea at this time can relieve greasy and help digestion.
