Cortisol
Cortisol is the body's main stress hormone. Chronically high cortisol can disrupt the cycle and worsen PMS symptoms.
Stress competes with reproductive hormones, so ongoing high cortisol can delay ovulation or intensify luteal symptoms.
Sleep, gentle movement, and not overtraining in the luteal phase help keep it in check.
