9 Side Effects of Drinking Too Much Tea

Some tea ingredients can make you feel queasy, especially if you drink a lot of it if it's empty.


According to research, coffee may relax the sphincter that keeps your stomach and esophagus apart, making it easier for acidic stomach contents to pass into your esophagus.

Pregnancy complications

When you drink tea or other beverages strong in caffeine during your pregnancy, you run the chance of experiencing problems including low birth weight and miscarriage.


Caffeine consumption on occasion may assist with some headache kinds. On the other hand, if used repeatedly, the opposite outcome may happen.
