November 30, 2022

This week, we're talking all things circadian rhythms. For those who work shift work, travel frequently and experience jet lag, or have otherwise atypical schedules, Dr. Greg Potter, sleep expert, is here to shed light on how best to optimize your sleep, nutrition, and eating schedules.

Dr. Greg Potter joins the WHOOP Podcast this week to cover a topic that many of our WHOOP members are curious about: the impacts of shift work and jet lag on your circadian health. Dr. Potter has a PhD from the University of Leeds focused on sleep, circadian rhythms, nutrition, and metabolism – in addition to being a qualified personal trainer and sports massage therapist. His work has been published in Time, BBC, Reuters, and the Washington Post. He sits down with VP of Performance Kristen Holmes to discuss how to navigate working difficult hours, how to think about nutrition, sleep, and exercise on an abnormal schedule, and how caffeine can even be a beneficial tool.
