The Science of Stress and Menstruation

When you experience acute or chronic stress (exams, job pressure, emotional distress, intense workout regimens), your hypothalamus releases Corticotropin-Releasing Hormone (CRH), which signal your adrenal glands to flood your system with cortisol. High cortisol suppresses GnRH release, telling your ovaries to pause ovulation temporarily.
