Walk your way to a sharper mind: How 40 minutes of walking boosts brain size

A recent study reveals that regular walking can increase the size of the hippocampus, a brain region crucial for memory, in older adults. Participants who walked 40 minutes three times a week experienced a 2% growth in hippocampal volume, defying age-related shrinkage. This simple exercise also improved cognitive function, offering a cost-effective way to combat cognitive decline.
