What about tea’s caffeine?

Your brain is stimulated by caffeine. It’s possible that you want to start your day feeling more alert in the morning. However, taking in too much caffeine can cause anxiety and jitters. Additionally, consuming caffeine late in the day can make it difficult to fall asleep.

You can select your tea according to how much caffeine you want to take in. Black tea typically contains the most caffeine and has approximately one third to one half the caffeine of coffee. Black tea contains more caffeine than green tea. Herbal teas do not contain caffeine, and decaffeinated tea contains little or no caffeine.
Is drinking tea bad for you?

When you drink tea, there are a few things to watch out for. First, drinking too much tea could cause kidney stones. This is due to the presence of oxalate in tea, which when combined with calcium can cause kidney stones.

Second, the herbs in some kinds of tea are not regulated by the government. Additionally, herbs may interact with any medications you may be taking. Always check with your doctor and read the ingredient label, Florek said.
