Drink Hot Tea

f you're a coffee-guzzler, consider going green. Coffee raises levels of the notorious stress hormone, cortisol, while green tea offers health and beauty, says Nicholas Perricone, MD, author of 7 Secrets to Beauty, Health, and Longevity.

Chamomile tea is a traditional favorite for calming the mind and reducing stress. And black tea may be a stress-fighter, too, researchers from University College London report. Participants who drank regular black tea displayed lower levels of cortisol, and reported feeling calmer during six weeks of stressful situations than those who drank a placebo with the same amount of caffeine.
