Exams, breakups, moving house, a hectic job: stress is part of life. Your body handles it with a cascade of hormones, including cortisol, and your cycle can feel the ripple.
Cortisol 101
Cortisol is made by your adrenal glands. It keeps you alert, releases sugar for quick energy, dampens inflammation and helps control your sleep-wake cycle. It is helpful in short bursts; the trouble comes when stress is relentless.
Stress and periods
The NHS lists stress as a common cause of late or missed periods. Many people also find PMS feels harder to handle in stressful weeks. But a missed period is not always stress, so rule out the other causes the NHS lists, such as pregnancy.
Stress signs to notice

Ways to lower the load
- Break big problems into small steps

Very high cortisol is usually a medical condition diagnosed by a doctor. For everyday stress, simple habits like sleep, movement and connection are what the NHS recommends.
