In this episode, Maggie McDaris, CEO and Co-Founder of Phase, breaks down the science and practical application of cycle syncing, explaining how each phase of the menstrual cycle influences energy, cognition, productivity, and overall performance. She walks listeners through the follicular, ovulatory, luteal, and menstrual phases, highlighting the unique strengths and challenges of each stage, including the often-overlooked immune and recovery considerations during the luteal phase. Maggie also explores the role of dopamine, healthy ways to pursue motivation and achievement, and how understanding your biology can help prevent burnout in a culture that often expects women to perform the same way every day. The conversation addresses the stigma surrounding menstrual cycles, the importance of involving men in the discussion, and how cycle awareness impacts sleep, circadian rhythms, and workplace success. Maggie concludes by sharing actionable tips for getting started with cycle syncing and explains how the Phase app helps women align their schedules with their biology to optimize health, productivity, and sustainable performance.
