Can You Drink Too Much Tea?
Yes, you can drink too much tea. While moderate tea consumption offers many health benefits, excessive intake can lead to several negative side effects.
Drinking too much tea can cause various problems, depending on factors like the type of tea, individual sensitivity, and the quantity consumed. These side effects range from mild to more serious:
- Anxiety and poor sleep: High caffeine content in many teas can disrupt sleep and increase anxiety levels. This effect varies between individuals, with some experiencing sensitivity at lower doses than others. [Source: Healthline, New Scientist, Reddit]

- Digestive issues: Excessive tannins in tea, particularly black tea, may irritate the stomach lining and cause issues such as upset stomach or heartburn. [Source: Teavivre]
- Iron deficiency: High tannin levels hinder iron absorption. Consuming large quantities of tea throughout the day could contribute to iron deficiency if not balanced with iron-rich foods. [Source: Reddit]

How Much Tea is Too Much?

The type of tea and its caffeine concentration also play significant roles.
Individual Sensitivity
It's crucial to understand that individual responses to tea vary significantly. Some individuals are more sensitive to caffeine and tannins than others. If you experience any of the aforementioned negative effects after drinking tea, reduce your intake.
