Consider a study from Stanford University. Aptly titled “Give Your Ideas Some Legs,” it asked participants to engage in mentally fatiguing tasks. One group took a break during which the participants sat and stared at a wall. Another group went on a six-to fifteen-minute walk during their break. After the break, both groups were tested for their creative insight. The participants who took the short walk demonstrated a 40 percent increase in creative insight over those who didn’t.
