Physical activity shows a strong link to improved cognitive function in older adults. Regular exercise is associated with increased blood flow to the brain, which supports the growth of new neurons and enhances memory and learning. Additionally, physical activity can help reduce the risk of cognitive decline and conditions like Alzheimer's disease by promoting the release of neuroprotective factors. Engaging in exercise not only boosts overall health but also maintains mental agility, allowing older adults to enjoy a higher quality of life.
