Women and girls need proper sanitation and hygiene facilities to maintain health and dignity. In this study we show how schoolgirls from a peri-urban community of Ghana, experience severe multidimensional 'hygiene poverty' when attending schools. Hygiene poverty was characterized by poor water and sanitation infrastructures and serious social and emotional challenges, including shaming and disciplining of their sanitation and menstrual practices, which forces girls to apply secretive coping strategies. We discuss the importance of changing the negative MHM discourses at schools and fostering supportive teaching methods in adolescent female health.
