Franzi Ruhnau is a social scientist, systemic coach, and founder of “Zyklus Power.” She makes it clear that knowledge about the menstrual cycle belongs where mental health is discussed on a daily basis—in the workplace. With a clear view of hormonal rhythms, exhaustion, and leadership, she shows how cyclical self-management makes the future of work healthier. Her book “Zyklus Power” will be published in April 2026 by Rowohlt Verlag.

At the PEOPLE & CULTURE FESTIVAL 2025, Franzi Ruhnau will be a speaker on the topic: “PMS as a Guide for the Future of the World of Work.”
