Scientists have evidence behind what many tea drinkers already know - a regular cuppa can help you recover more quickly from everyday life stresses.

The study of black tea - instead of green or herbal varieties - found it helps cut levels of the stress hormone cortisol circulating in the blood.

They found people who drank tea were able to de-stress more quickly than those who drank a tea substitute.
