One of tea's greatest benefits come from its natural ability to hydrate our bodies - as opposed to coffee, which promotes the opposite because it's a diuretic. That's why you may find yourself constantly running to the bathroom after several cups of coffee. Tea also contains polyphenols, which are molecules that bear strong anti-aging qualities. And if you have acne, you're in luck: tea also naturally lowers stress levels and is a cortisol antagonist. Drinking tea will help to prevent future breakouts.
