Exercise enhances cognitive functions in older adults by improving blood flow to the brain and promoting neurogenesis, the creation of new neurons. Regular physical activity has been linked to better memory, attention, and executive function capabilities. Aerobic exercises, such as walking, swimming, and cycling, are particularly effective in stimulating brain health. Additionally, exercise may reduce the risk of cognitive decline and diseases such as Alzheimer's by decreasing inflammation and promoting mental clarity. Finally, engaging in social activities during exercise can also support emotional and psychological well-being, further contributing to cognitive health in older adults.
