Exercise Grows New Brain Cells
Aerobic exercise stimulates neurogenesis — the growth of new neurons — in the hippocampus, the brain region responsible for memory and learning. This isn't metaphorical; exercise literally makes your brain bigger and more capable.
The Mood Effect
A single 30-minute exercise session improves mood for up to 12 hours. Regular exercise is as effective as antidepressants for mild to moderate depression, with better long-term outcomes and no side effects.
The Lifespan Connection
Regular exercisers live 3-7 years longer than sedentary people, with the biggest gains coming from the transition from inactive to moderately active. The dose-response curve means even small amounts of exercise produce significant longevity benefits.
