The way menstruation is experienced depends not only on physical symptoms, but also on the social context in which it occurs. A study conducted in Spain with more than 4,000 participants analyses how menstrual stigma influences daily life, social participation and well-being.

This study, led by the INGENIO Institute, a joint centre of the Universitat Politècnica de València (UPV) and the Spanish National Research Council (CSIC), has been published in the journal BMC Women's Health. It is the fourth publication of a research project that provides one of the first insights into menstrual health in Spain — after addressing menstrual education, stigma and access to healthcare — and now focuses on the social impact of menstruation on everyday life.

The results show that menstruation continues to influence everyday activities. Only 15.4% of participants say they maintain their routine without change on those days, while many adapt their behaviour to avoid potential discomfort or exposure. Among the most common strategies are avoiding certain types of clothing (36%), avoiding white garments (48%), reducing sports activities (21%) or limiting activities such as swimming or going to the beach (22%).
