Drinking black tea might be the easiest way to beat stress, say English researchers.
According to a University College London study of 75 adults, drinking four cups of plain black tea a day appears to cut levels of the hormone cortisol by a remarkable 20 per cent. (Cortisol is a potentially dangerous ‘stress hormone’, which ramps up blood pressure and may even make your body more vulnerable to disease).
The tea-drinkers also claimed to feel calmer and better able to deal with stressful events than a control group who drank other caffeinated beverages.
