Episode description
Story at-a-glance
- The brain and muscles maintain constant two-way communication — muscles release biochemical signals that travel to the brain, while the brain coordinates movement and balance
- Regular physical activity enhances your brain function through multiple mechanisms, such as boosting neurogenesis, increasing cerebral blood flow, reducing inflammation and building cognitive reserve
- A 2024 study revealed that both biochemical signals (myokines) and mechanical forces from muscle contractions during exercise independently contribute to motor neuron growth and development
- Moderate-intensity exercise for at least 30 minutes is optimal for brain health, while excessive high-intensity workouts elevate cortisol and negate longevity benefits
- Tips to tailor your routine for maximum cognitive gains are included below, such as elevating your heart rate, allowing time for results, diversifying workouts and incorporating social activities
