- This increased travel distances and intensity, shaping our physiology for high activity levels.
Exercise Benefits
- Exercise increases blood flow to the brain, delivering nutrients and supporting neuron function.
- Muscles produce myokines that travel to the brain, promoting neuron growth and survival.
