Exercise promotes better brain health by increasing blood flow and oxygen to the brain, stimulating the release of various neurotransmitters, and encouraging the growth of new neurons. Regular physical activity can enhance cognitive function, improve memory, and reduce symptoms of anxiety and depression. Exercise has also been associated with increased levels of BDNF (brain-derived neurotrophic factor), a protein that supports neuron health and helps fend off age-related cognitive decline. This holistic benefit makes exercise a key component of mental wellness.
