803. Work with Your Cycle: Boost Energy, Mood and Fertility
Almost 30
Progesterone’s Role Across the Cycle
Sarah explains why women have both estrogen and progesterone and how progesterone shapes the second half of the cycle.
In this episode, Lindsey sits down with Dr. Sarah Hill, award-winning researcher + author of This Is Your Brain on Birth Control + her new book The Period Brain. Sarah shares what’s really happening in your brain and body throughout the cycle—and why so much advice leaves women guessing.
Ahead, Sarah reveals why PMS hits so hard, how progesterone impacts mood + energy, and the surprising ways hormones shape relationships, creativity, and decision-making. Learn what your body needs in each phase—and how ignoring those needs affects fertility, mental health + more.
You’ll also hear science most doctors skip, why women often feel “off” in modern life, and the simple shifts that make work, love, and wellness easier. This conversation is practical, myth-busting, and designed to help you start working with your cycle right away.
