Exercise has been linked to improved cognitive function through various mechanisms. Physical activity increases blood flow to the brain, promoting the delivery of oxygen and nutrients essential for brain health. Additionally, exercise stimulates the production of neurotrophic factors, which support neurogenesis and synaptic plasticity, crucial for learning and memory. It has also been shown to improve mood and reduce anxiety, enhancing overall cognitive performance. Engaging in regular exercise, whether through aerobic activity, strength training, or even recreational sports, can significantly benefit brain health, particularly in older adults.
