Hormonal fluctuations across the menstrual cycle are increasingly recognized as meaningful contributors to variations in cognition, emotional regulation, and daily functioning. However, empirical evidence remains fragmented across disciplines, with studies differing widely in methodological rigor, outcome measures, and approaches to menstrual phase classification. This lack of integration limits the field’s ability to draw coherent conclusions about how cycle-related changes influence cognitive load and work productivity—domains of growing significance for women’s health and occupational wellbeing. This narrative review addresses this gap by synthesizing findings from nineteen empirical studies spanning neuroscience, psychology, occupational health, and digital menstrual tracking. A structured search of PubMed, Scopus, and Web of Science was used to identify eligible studies. Data were then extracted using a standardized analytical protocol. The findings reveal domain-specific patterns of cognitive variation, with the most consistent differences observed in reaction time, attentional stability, and temporal anticipation. Cognitive-emotional processes—including rumination, stress reactivity, and negative attentional bias—showed particularly pronounced fluctuations during the luteal and premenstrual phases, especially among individuals with PMS or PMDD, and were associated with reduced efficiency, motivation, and routine management. Digital tracking tools provided additional insight into menstrual variability but demonstrated methodological limitations that affect their reliability for studying cognitive and functional outcomes. Overall, the evidence indicates that menstrual-cycle-related changes in cognition and emotional processing interact with symptom burden to shape cognitive load and everyday productivity. Strengthening methodological rigor, incorporating validated measures, and improving menstrual health literacy may enhance both research precision and practical strategies for supporting individuals across menstrual cycle phases.
