Scientists Identify Daily Step Count Linked to Better Cognitive Performance
Key Points:
- A study by Baylor College of Medicine involving over 3,000 U.S. adults found that walking more steps daily is linked to better cognitive performance, particularly in sustained attention, cognitive control, and decision-making.
- Participants were grouped by average daily steps—around 5,000, 9,000, and 14,000—and each additional 1,000 steps correlated with modest improvements in brain function, highlighting the benefits of consistent long-term physical activity.
- Higher blood pressure was associated with poorer cognitive scores, but those with greater physical activity tended to have lower blood pressure, suggesting cardiovascular health partly mediates the relationship between walking and cognition.
- The study is observational and measured cognition only once after 14 years, so causation cannot be confirmed; however, experts emphasize that regular walking supports brain health through improved vascular function, reduced inflammation, and enhanced neurotrophic factors.
- Health guidelines recommend adults aim for 150 to 300 minutes of moderate-to-vigorous physical activity weekly, achievable by incorporating more walking into daily routines, such as taking stairs or parking farther away.
