Exercise promotes neuroplasticity in the brain by facilitating the growth and development of new neural connections. Physical activity increases blood flow and oxygen to the brain, enhancing the production of brain-derived neurotrophic factor (BDNF), which supports learning and memory. Engaging in regular aerobic exercise can also boost cognitive function and protect against age-related decline, making it vital for maintaining mental sharpness. Through consistent movement, individuals can enhance their brain health and cognitive capabilities over time.
