Dr. Matthew Walker is a world-renowned neuroscientist, sleep expert, and the bestselling author of “Why We Sleep.” In this conversation, we explore sleep not as a passive state, but as the biological foundation of life itself—the platform from which wakefulness emerges. We dive into the architecture of sleep, its vital role in immune function, disease prevention, memory, mood, and performance. We also touch on dreams, sleepwalking, and the hidden costs of even modest sleep disruption. I share my own long, complicated relationship with sleep—and what I’ve learned in the process. Matthew is brilliant. His insights are profound. And this re-released conversation just might change your life. Enjoy!
