Although we all wish we could go on a springtime stroll with our pets in the middle of the day, it turns out that the act of walking, not necessarily the environment, is what matters when it comes to creativity. In a study conducted at Stanford, researchers found that creativity levels were higher when a person was walking, and continued to be high even when they sat back down after a walk. Being indoors, outdoors, on a treadmill, or on a sidewalk didn’t make much difference to the participants — all that mattered was that they were up and moving around, rather than sitting.
