WHOOP Podcast

Welcome Back to the WHOOP Podcast's Science of Human Performance Series! This week, WHOOP Global Head of Human Performance and Principal Scientist Dr. Kristen Holmes sits down with WHOOP SVP of Research, Algorithms, and Data Emily Capodilupo for a deep dive into the science behind the WHOOP Sleep Score and the habits that have the biggest impact on restorative sleep.
Emily explains why sleep consistency is one of the strongest predictors of performance, recovery, and long-term health, and walks through the four metrics that make up your WHOOP Sleep Score: sleep duration, consistency, efficiency, and sleep stress. Together, Dr. Holmes and Emily unpack how nutrition, exercise, alcohol, stress, and your daily routines influence sleep quality, share practical strategies for falling asleep and staying asleep, and discuss how poor sleep can sometimes be an early signal of underlying health issues.
