In this Huberman Lab Essentials episode, my guest is Dr. Gina Poe, PhD, a Professor of Integrative Biology and Physiology at the University of California, Los Angeles (UCLA). We discuss the architecture of sleep and how each stage supports distinct functions, including memory consolidation, creativity, brain restoration, and emotional processing. We also explain science-supported tools to improve sleep quality, support cognitive performance, and hormone balance.
