Increase anxiety, stress, and restlessness

Caffeine is found naturally in tea leaves. Caffeine from tea, or any other source, in excess, may add to sensations of worry, tension, and restlessness. Depending on the variety and brewing technique, an average cup (240 ml) of tea contains 11-61 mg of caffeine. Black teas have more caffeine than green and white teas, and the longer you steep your tea, the more caffeine it contains.

Caffeine dosages of less than 200 mg per day, according to research, are unlikely to induce considerable anxiety in most people. However, some people are more susceptible to caffeine's effects than others and may need to reduce their intake even more. If you realize that your tea habit is making you restless or uneasy, it might be a sign that you have had too much and should cut back to alleviate symptoms. You might alternatively choose caffeine-free herbal teas. Because they are not sourced from the Camellia sinensis plant, herbal teas are not considered real teas. Instead, they're prepared using caffeine-free components like flowers, herbs, and fruit.
