The hypothalamus, a key brain region that regulates menstruation, is influenced by factors such as exercise, sleep, and stress. When functioning properly, it triggers hormone release to ensure regular periods. However, stress raises cortisol levels, which can interfere with the hypothalamus, pituitary gland, and ovaries, potentially causing delayed or lighter periods. #MenstrualHealth #StressAndPeriods #Cortisol #HormonalBalance #PeriodProblems #WomenHealth
