Physical activity benefits cognitive function by enhancing blood flow to the brain, which supports neurogenesis and overall brain health. Regular exercise is associated with improved memory, concentration, and cognitive flexibility. It also increases the production of neurotransmitters like serotonin and dopamine, which help in mood regulation and reduce symptoms of anxiety and depression. Furthermore, engaging in physical activities can lead to better stress management, promoting a healthier and more resilient psychological state, ultimately contributing to improved mental clarity and cognitive performance.
