The relationship between physical fitness and cognitive function is well established, as regular exercise promotes brain health. Physical activity increases blood flow to the brain, enhancing oxygen and nutrient delivery, which can improve memory, concentration, and overall mental performance. Exercise is also associated with the release of neurotransmitters like dopamine and serotonin, which support mood regulation and cognitive processing. This connection highlights the importance of maintaining an active lifestyle not just for physical health but also for enhancing mental acuity.
