Meditation is often credited with helping people feel more focused and energetic, but are the benefits measurable?

A new study suggests that they are. When researchers tested the alertness of volunteers, they found that the practice proved more effective than naps, exercise or caffeine. The results were presented at a recent conference of the Society for Neuroscience.

The researchers, led by Prashant Kaul of the University of Kentucky, took 12 students who did not meditate and taught them the basics in two short sessions.

Then, over a series of weeks, the students were asked to come in and take a test devised to measure skills like reaction time. The tests involved a series of visual cues on a display screen that the volunteers had to react to by pushing the correct button.
