Recent studies suggest that walking stimulates our creative mind is at its most creative at three miles per hour, the speed of a moderately paced stroll. Stanford University researchers divided participants into two groups: walkers and sitters. They then administered a test designed to measure creativity. They found that creative thinking was “consistently and significantly” higher for the walkers than the sitters. It didn’t take a lot of walking to boost creativity, either—anywhere from 5 to 16 minutes.
