Period health is shaped by more than biology and comfort can swing wildly from one place to the next. Globally, only 41% of schools have menstrual hygiene facilities, while 75% of women experience painful periods. The same cycle that lasts about 28 days also connects to education gaps, product costs, and even infection risk, and the details vary sharply across countries and communities.
