Franzi Ruhnau is a social scientist, systemic coach, and founder of “Zyklus Power.” She makes one thing clear: cycle awareness belongs where mental health is negotiated every day – in the workplace. With a sharp focus on hormonal rhythms, exhaustion, and leadership, she shows how cyclical self-leadership can make the future of work healthier. Her book “Zyklus Power” will be published in April 2026 by Rowohlt Verlag.

At the PEOPLE & CULTURE FESTIVAL 2025, she will speak on the topic “Mental health is not a sprint: How cyclical work prevents burnout.”
