Exercise positively affects the brain's neuroplasticity by promoting the growth of new neurons and enhancing synaptic connections. Physical activity increases the production of neurotrophic factors, such as BDNF (Brain-Derived Neurotrophic Factor), which support learning, memory, and overall cognitive function. Regular exercise can also improve mood and reduce symptoms of anxiety and depression, contributing to mental resilience. Through these mechanisms, exercise fosters a brain environment conducive to adaptation and learning throughout life.
