New research has found that walking boosts your creativity — 81 percent of people studied were more creative when walking than sitting.

“Walking opens up the free flow of ideas,” the researchers state, “and it is a simple and robust solution to the goals of increasing creativity and increasing physical activity.”

Researchers at Stanford University tested subjects on creative thinking while the subjects were walking and seated as well as after they walked. Scores were higher for the walkers than the sitters, but the post-walkers also showed improved scores, what the researchers called a residual effect. The research was published in the Journal of Experimental Psychology: Learning, Memory, and Cognition.

So: Feeling stumped? Trying to determine how to proceed on a project, a task, a plan? Take a walk, and the light bulb over your head might just illuminate.
