The Doctor's Farmacy With Mark Hyman, M.d.

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.

He is currently a Professor of Neuroscience and Psychology at the University of California, Berkeley, and director of the Center for Human Sleep Scien
