Exercise positively impacts brain health, particularly in aging adults, by enhancing cognitive function and reducing the risk of neurodegenerative diseases. Regular physical activity increases blood flow to the brain, promoting neurogenesis and improving mood and mental well-being. Exercise also helps alleviate symptoms of anxiety and depression, which are common among older populations. Furthermore, engaging in physical activity is linked to improved memory and attention, leading to better quality of life. Overall, exercise serves as a vital component of healthy aging.
