There is a significant connection between walking and creativity:

Oppezzo designed an elegant experiment. A group of Stanford students were asked to list as many creative uses for common objects as they could. A Frisbee, for example, can be used as a dog toy, but it can also be used as a hat, a plate, a bird bath, or a small shovel. The more novel uses a student listed, the higher the creativity score. Half the students sat for an hour before they were given their test. The others walked on a treadmill.

The results were staggering. Creativity scores improved by 60 percent after a walk.

A few years earlier, Michelle Voss, a University of Iowa psychology professor, studied the effects of walking on brain connectivity. She recruited 65 couch-potato volunteers aged 55 to 80 and imaged their brains in an MRI machine. For the next year, half of her volunteers took 40-minute walks three times a week. The other participants kept spending their days watching Golden Girls reruns (no judgment here; I love Dorothy and Blanche) and only participated in stretching exercises as a control. After a year, Voss put everyone back in the MRI machine and imaged their brains again. Not much had happened to the control group, but the walkers had significantly improved connectivity in regions of the brain understood to play an important role in our ability to think creatively.

Walking changes our brains, and it impacts not only creativity, but also memory."
