The simple habit that improves memory and concentration at any age

A new study published in Scientific Reports found a direct link between daily walking and improvement in cognitive functions. Researchers tracked 3,093 participants aged 18–93 and found that those who walked more steps performed better in tests of attention, memory, and decision-making. The effect remained even after accounting for blood pressure.

A new study published today (Wednesday) in the scientific journal Scientific Reports reveals a direct link between simple daily physical activity and improvement in cognitive functions. Researchers tracked data from 3,093 participants aged 18 to 93, using step data from Fitbit activity trackers and cognitive tests. Participants were divided into three groups based on their average daily steps: about 5,100, about 8,900, and about 14,200 steps. The results consistently showed that groups that walked more steps performed better in tasks requiring sustained attention, cognitive control, and decision-making. The researchers also examined the link between blood pressure and brain function. Higher systolic blood pressure was found to be associated with poorer performance in decision-making tasks. However, the positive relationship between step count and cognitive performance remained even after accounting for the effect of blood pressure, suggesting that walking has an independent and unique benefit for brain health, beyond its positive effect on the cardiovascular system. The researchers emphasize that this is an observational study that does not prove cause and effect, and that people with better cognitive function may tend to be more active to begin with. Further studies are needed to confirm the findings.
