People associate movement with progress and stillness with a lack thereof, explains study author Dolores Albarracín, Ph.D., professor of psychology at the University of Illinois at Urbana-Champaign. In other words, physical activity (as light as walking) can jumpstart brain activity while sitting can put your mind in a more dormant state.
Albarracín says movement can encourage you to finish any task, whether it’s an errand or a work project.
The bottom line:
If you find yourself procrastinating, a three-minute walk is enough to kick your brain into gear, Albarracín says. The more time and intensity you can dedicate to exercise, the stronger the effect.
