"Have a cup of tea. That'll make you feel better."

Granny was right; tea really is good for your health! But who knew it was a legitimate stress buster too? A new study in London suggests that drinking black tea helps reduce stress and promotes relaxation. According to webmd.com, researchers determined that black tea drinkers were able to de-stress more quickly and had lower levels of the stress hormone cortisol after exposure to stress than those who drank a fake tea substitute.

Black tea is rich in catechins, polyphenols, flavonoids and amino acids, which are linked to a number of health benefits. So whether you're having a hard day at the office, studying for midterms or dealing with the pressures of motherhood, have a cup of black tea and feel the stress melt away (well, maybe a little).
