Unda Cycle

Unda Cycle is a Danish brand founded by Thilde Irene, dedicated to sharing knowledge about the menstrual cycle and helping women understand their bodies’ rhythms. Its name means “wave” in Latin, reflecting the changing hormonal phases and experiences of the cycle. Through cycle education, teaching and events, Unda Cycle encourages a more positive, attentive relationship with the body, emphasizing that its natural rhythms are unique and do not mean it is broken.

The brand offers educational programs for schools and institutions, as well as private events with different formats and concepts. Its Cyklus Logbog is an analogue journal designed as a quiet space to record thoughts, sensations and experiences throughout the cycle, helping users tune in without digital distractions. Unda Cycle also sells cycle-inspired products, including a necklace, posters, and stickers featuring its logo and spiral design. Founded by Thilde Irene, who draws inspiration from the rhythms of nature around her home near the North Sea, the brand brings together education, reflection and creative products to make cycle awareness accessible in everyday life.
