This research paper investigates the significant but often underestimated impact of stress on women's menstrual cycles. It highlights how stress, particularly chronic stress, can disrupt hormonal mechanisms, leading to irregularities in the menstrual cycle. The study emphasizes the role of cortisol release from the adrenal glands in influencing key hormones like follicle-stimulating hormone, estrogen, and progesterone. The paper also explores the broader impact of environmental factors, such as global events like wars and pandemics, on women's menstrual health. To address irregular periods caused by stress, the paper discusses a variety of medical treatments, including birth control pills and hormone replacement therapy, as well as non-medical alternatives like adaptogenic herbs and mind-body therapies. The research methods include case studies, a comprehensive review of experimental studies, and a multifaceted data analysis to understand the intricate relationship between chronic stress and menstrual irregularities and to evaluate the effectiveness of various interventions.
