Walking Boosts Brain Health: Study Finds 2% Increase in Senior Hippocampus Size
June 23, 2025
A recent study published in the Proceedings of the National Academy of Sciences reveals that walking can significantly increase the size of the hippocampus, a brain region essential for memory.
Walking stands out as a low-impact, accessible, and cost-free exercise option, eliminating the need for gym memberships or special equipment.
These findings challenge the notion that memory loss is an inevitable part of aging, suggesting that even mild exercise can lead to improvements in brain health.
The study underscores the importance of integrating brisk walking into daily routines for enhanced brain health, highlighting that it's never too early or too late to begin.
Participants who engaged in walking demonstrated better memory function and faster processing speeds compared to those in the control group.
Walking not only increases blood flow to the brain but also stimulates growth hormone production and promotes the formation of new synapses, thereby enhancing cognitive function.
The research focused on seniors aged 55 to 80, comparing the effects of stretching exercises with those of walking for 40 minutes three times a week.
MRI scans indicated that the hippocampus of participants in the walking group increased in size by an average of 2%, counteracting the typical shrinkage associated with aging.
