In this eye-opening episode, Dr. Gabrielle Lyon is joined by renowned sleep scientist Dr. Rebecca Robbins to uncover the real science behind sleep—and why it may be the most underestimated pillar of health and longevity. Together, they break down how sleep actually works, from the homeostatic sleep drive to the critical role of circadian rhythm, and explain why sleep is far from a passive state for the brain.

Dr. Robbins reveals how sleep deprivation impacts cognitive health, emotional regulation, blood pressure, appetite, and long-term disease risk, including Alzheimer’s. They also tackle modern sleep disruptors like social jet lag, excessive snoozing, travel, and poor routines, while separating fact from fiction around sleep medication, naps, and wearable sleep tech. Packed with practical, evidence-based strategies, this conversation will change how you think about rest—and empower you to optimize sleep for better performance, resilience, and long-term health.
