Black tea contains 2% to 4% caffeine, which affects thinking and alertness, increases urine output, and may reduce the symptoms of Parkinson's disease. It also contains antioxidants and other substances that might help protect the heart and blood vessels.
The side effects of drinking too much black tea include difficulty sleeping, headaches, nervousness, diarrhea, irritability, irregular heart rate, confusion, heartburn, tremors in your extremities and possibly convulsions. These side effects are all a result of the caffeine content in black tea. If you are used to drinking black tea regularly -- particularly in larger quantities -- you may develop a physical and psychological dependence on the beverage, again, primarily due to the caffeine content.
