Exercise has protective effects on brain health, including improved cognitive function, reduced risk of depression, and enhanced mood. Physical activity increases blood flow and oxygen to the brain, promoting the growth of new neurons and connections through a process called neurogenesis. Regular exercise has been linked to better memory, learning, and overall mental clarity. Furthermore, it can reduce the risks of neurodegenerative diseases such as Alzheimer’s. By improving stress management and emotional resilience, exercise makes a substantial contribution to mental well-being.
