How to Get Smarter, One Breath at a Time

Many people who meditate claim the practice restores their energy, allowing them to perform better at tasks that require attention and concentration. If so, wouldn't a midday nap work just as well? No, says Bruce O'Hara, associate professor of biology at the University of Kentucky. In a study to be published this year, he had college students either meditate, sleep or watch TV. Then he tested them for what psychologists call psychomotor vigilance, asking them to hit a button when a light flashed on a screen. Those who had been taught to meditate performed 10% better—"a huge jump, statistically speaking," says O'Hara. Those who snoozed did significantly worse. "What it means," O'Hara theorizes, "is that meditation may restore synapses, much like sleep but without the initial grogginess."

Not surprisingly, given those results, a growing number of corporations—including Deutsche Bank, Google and Hughes Aircraft—offer meditation classes to their workers. Jeffrey Abramson, CEO of Tower Co., a Washington-based development firm, says 75% of his staff attend free classes in transcendental meditation. Making employees sharper is only one benefit; studies say meditation also improves productivity, in large part by preventing stress-related illness and reducing absenteeism.

Another benefit for employers: meditation seems to help regulate emotions, which in turn helps people get along. "One of the most important domains meditation acts upon is emotional intelligence—a set of skills far more consequential for life success than cognitive intelligence," says Davidson. So, for a New Year's resolution that can pay big dividends at home and at the office, try this: just breathe.
