Sleepwalking, Insomnia, Circadian Rhythms: The Incredible Science of Sleep — Dr. Guy Leschziner

In this episode, I speak with Professor Guy Leschziner, a consultant neurologist and leading sleep specialist who has spent over a decade as the clinical lead at one of Europe's largest sleep disorder centers. Drawing on insights from neuroscience, clinical practice, and evolutionary biology, Guy explores the fascinating world of sleep—from its biological functions to its profound impact on our physical and mental health. Expect to learn: — Why studying the extremes of human behavior helps us understand normal brain function — How sleep affects everything from immune function to cognitive performance — The surprising way our brain's "glymphatic system" cleans toxins during deep sleep — Why insomnia treatments like CBT-I are so effective and how they work.
