Sleep is not just a luxury—it’s a foundational pillar of health that influences nearly every aspect of our well-being. Sleep deprivation doesn’t just cause fatigue; it disrupts hormones, drives inflammation, damages metabolism, and accelerates aging. From the gut microbiome to stress hormones like cortisol, sleep is deeply intertwined with brain, immune, and metabolic health. Yet our modern world—filled with late-night screens, ultra-processed foods, and chronic stress—works against quality rest.

In this episode, I discuss, along with Dr. Matt Walker and Shawn Stevenson, why we need to address sleep as a core health priority to unlock healing, prevention of chronic disease, and renewed vitality.
