PERIOD founder and Harvard College student Nadya Okamoto offers a manifesto on menstruation and why we can no longer silence those who bleed—and how to engage in youth activism.

Throughout history, periods have been hidden from the public. They’re taboo. They’re embarrassing. They’re gross. And due to a crumbling or nonexistent national sex ed program, they are misunderstood. Because of these stigmas, a status quo has been established to exclude people who menstruate from the seat at the decision-making table, creating discriminations like the tampon tax, medicines that favor male biology, and more.

Period Power aims to explain what menstruation is, shed light on the stigmas and resulting biases, and create a strategy to end the silence and prompt conversation about periods.

What reviewers said

"A must-read for anyone who wants to make change at the state and national levels.”
"If you’re looking for a way to turn your anger about gender inequality into action, this book is a must read. You’ll learn a great deal about menstrual inequities and the intersectional impacts created because of our failure to address them. This is a how-to handbook on what you can do to change that."
“[T]ruly intersectional and…a useful guide for activists inspired by this work…A smart, honest, and comprehensive education on movement building and menstrual rights.”
"Okamoto intends to end menstrual stigma and taboo--full stop. This book is a game-changer for anyone who has ever had a period—or knows anyone who has had or will have one."
Alma Gottlieb, co-author of Blood Magic: The Anthropology of Menstruation
"Period Power is a must-read for women and men to educate themselves both on the history and stigma of menstruation, period policy, and its representation in the media -- but also concrete action items for making a difference. Nadya's ability to combine knowledge with action is what makes Period Power so powerful."
Caity Begg, founder of Authentic.Social
"Nadya Okamoto’s Period Power takes a brave, necessary look at menstruation. Filled with both personal narratives and historical context, this book should be required reading for not just young students around puberty age, but adults as well. We must, as a society, reframe and relearn how we discuss and understand bleeding, and Okamoto’s book is a necessary first step."
