New research conducted by the UCL Institute of Sport, Exercise and Health (ISEH) has revealed surprising findings about women's cognitive abilities during menstruation. Contrary to common beliefs, the study found that women actually perform better in cognitive tests while on their period. Despite feeling worse than usual during their menstrual cycle, women showed improved mental agility, accuracy, and attention to detail during this time. This challenges existing assumptions about how women perform in sports and other activities while menstruating. The results of the study could potentially change the way female athletes are perceived and supported during their periods. The lead author of the study described the findings as "surprising" and emphasized the importance of reevaluating current beliefs about women's abilities during menstruation.
