This week on the WHOOP Podcast, WHOOP Global Head of Human Performance, Principal Scientist, Dr. Kristen Holmes sits down with Dr. Gina Poe, neurobiologist and expert in REM sleep and memory consolidation. Together, Dr. Holmes and Dr. Poe unpack what actually happens when you’re asleep and why sleep is essential not just for memory, but emotional resilience, longevity, and high performance.

This episode breaks down the different stages of sleep and how they reshape the brain, regulate the nervous system, and actually clean the brain. Dr. Holmes and Dr. Poe provide insight on daily habits to optimize sleep quality, including timing, exercise, and stress regulation.
