What are the side effects of tea?

As with any food, consuming too much tea can cause some negative effects.

1. Low iron absorption
Tea is a beverage rich in a class of compounds called tannins or tannic acid. Tannins can bind iron in foods and cause iron to be blocked from the digestive system. As a result, iron deficiency may occur in your body.

2. Increased anxiety, stress and restlessness and decreased sleep quality
Tea leaves naturally contain caffeine. Although it is known to many people that excessive caffeine consumption causes insomnia, few people know that stress, anxiety, and restlessness can be caused by caffeine. Tea placed in a 240 ml liquid-receiving cup may contain between 11 and 61 mg of caffeine, depending on the brewing method.

3. Headache
Intermittent caffeine intake can help ease certain types of headaches. However, when used chronically, it may have the opposite effect. Caffeine consumption should be considered in chronic headaches, the cause of which cannot be explained.
