Welcome back to the WHOOP Advanced Labs series! This week on the WHOOP Podcast, Dr. Hazel Wallace, medical doctor, registered nutritionist, and member of the WHOOP Medical Advisory Board, joins WHOOP SVP of Research Algorithms and Data Emily Capodilupo for a powerful conversation about women’s health, nutrition, and the hormonal milestones that shape our lives.

From the reality that most medical research is based on male bodies to the overlooked nutritional needs of women across the menstrual cycle, perimenopause, and beyond, Dr. Wallace breaks down what women actually need to thrive. Emily and Dr. Wallace explore common symptoms of hormonal fluctuations, which supplements could be useful in your diet, postpartum nutrient depletion, and why many women are dismissed when addressing symptoms like fatigue, brain fog, and hair loss. Dr. Wallace shares her experience with PCOS, and the difficulties she faced trying to get a diagnosis despite being a medical doctor herself. Whether you struggle with underlying symptoms of hormone imbalance or are just looking to improve your nutrition, Dr. Wallace shares her top tips for feeling you best and advocating for your health.

Welcome to the WHOOP Research Series, where we breakdown into the extensive, scientific research conducted by the WHOOP Performance Science team. On this week’s episode, WHOOP Global Head of Human Performance, Principal Scientist, Dr. Kristen Holmes sits down with WHOOP Senior Research Scientist Dr. Greg Grosicki to unpack the latest WHOOP Research Study on Heart Rate Variability Coefficient of Variation or HRV-CV. Using data from 21,000+ WHOOP members and 2 million nights of sleep, Dr. Holmes and Dr. Grosicki reveal why day-to-day stability in your HRV may matter more than the number itself. HRV-CV proves to outperform traditional metrics in detecting the real impact of alcohol, sleep consistency, and metabolic health, making it a great measure of healthspan. By looking deeper into the study, Dr. Holmes and Dr. Grosicki explains how HRV-CV can help you program your training smarter, improve your healthspan and build autonomic resilience. This episode unpacks how measuring HRV-CV isn’t just about performance, but risk stratification and understanding your physiology over-time, not just day-to-day.

On this months edition of The WHOOP Podcast, WHOOP SVP of Research, Algorithms, and Data Emily Capodilupo sits down with longevity researcher, bioethicist, Scholar in Residence at the American Federation for Aging Research, Dr. Raiany Romanni-Klein to explore how society should be handling aging.
