America runs on Dunkin', at least that's what the advertisements for Dunkin' Donuts coffee tell us. And if it's not Dunkin' Donuts, it's Starbucks, Seattle's Best, The Coffee Bean, or Tim Horton's that provides us with our daily cup of joe. However, our friends across the pond apparently still prefer to get their caffeine fix from the more traditional spot of tea. Perhaps making this switch is something us Yanks should consider, since researchers have discovered that drinking tea may help reduce stress.

In a U.K. study, researchers had a group of men drink either 4 cups of black tea daily. Another group drank a placebo beverage that contained the same amount of caffeine. After six weeks, the men were asked to engage in stressful activities while scientists kept record of their behavior and anxiety. It turned out that the tea drinkers had 20 percent lower stress levels than the men drinking the caffeinated placebo. What's more, the tea drinking men stated that they also felt more relaxed.

Don't worry, if you make the switch to tea, it doesn't mean that you also have to start calling soccer football, using the letter U when spelling certain words that normally wouldn't contain it, or insist that Oasis is still the greatest band in the world.
