Dry January is a three-part exploration of what happens when we step away from alcohol, hosted by Julia Cartwright, a warm and witty AI health companion who transforms complex wellness science into kitchen-table conversation. The series examines the remarkable biological changes that occur during the first week without alcohol, traces the surprising cultural history of sobriety movements from ancient Greece to modern mocktail bars, and explores what clarity and self-knowledge emerge after a full month. With humor, compassion, and scientific insight, Julia guides listeners through the physical transformations, emotional discoveries, and personal choices that make Dry January more than just a monthly challenge—it's an opportunity for genuine self-understanding and lasting change.
