"Creative thinking improves while a person is walking and shortly thereafter, according to a study co-authored by Marily Oppezzo, a Stanford doctoral graduate in educational psychology, and Daniel Schwartz, a professor at Stanford Graduate School of Education.

The study found that walking indoors or outdoors similarly boosted creative inspiration. The act of walking itself, and not the environment, was the main factor. Across the board, creativity levels were consistently and significantly higher for those walking compared to those sitting.

The overwhelming majority of the participants in these three experiments were more creative while walking than sitting, the study found. In one of those experiments, participants were tested indoors – first while sitting, then while walking on a treadmill. The creative output increased by an average of 60 percent when the person was walking, according to the study."
