There is a strong correlation between fitness and brain health. Regular physical activity enhances cognitive function, supports memory, and may reduce the risk of cognitive decline as one ages. Exercise increases blood flow and oxygen supply to the brain, promoting the growth of new neurons and facilitating neuroplasticity. Furthermore, engaging in physical activities can improve mood and reduce stress levels, both of which contribute to better cognitive performance. Maintaining an active lifestyle is crucial for preserving brain health and enhancing mental agility across the lifespan.
