The Bright side of Coffee

Coffee helps you see the bright side - The Body Odd: "For some people, it’s somewhere between the third or fourth cup of coffee when they begin feeling human. While people commonly guzzle a cup of joe to perk up, it turns out caffeine can do more than simply wake people. Researchers found that caffeine helps the brain process positive words faster.
Caffeine indirectly boosts dopamine transmission—a neurotransmitter that aids in reward-based learning—and Lars Kuchinke, a junior professor at Germany's Ruhr University, suspected this might lead to better acumen with word recognition by enhancing activity in the brain’s left hemisphere, which controls language. Researchers already know that people who consume normal levels of caffeine perform better at basic cognitive tasks. "
