Walking May Improve Your Attention Span

A 14-year analysis of over 3,000 adults' daily step counts and cognitive assessments found that people who walked more steps per day performed better on tests of sustained attention, cognitive control, and delay discounting; each additional 1,000 steps correlated with incremental improvements.

Only one cognitive assessment was performed per person over the study period, so the research cannot show how increasing or decreasing steps changes individual performance over time.
