Cortisol, Stress & Perimenopause
Sara Gottfried's case for steadying cortisol first, especially in perimenopause, through sleep, light, stress and training, with an honest line on what the science does and does not support.
Gottfried argues that for many women, especially heading into perimenopause, the stress-hormone system is the place to start. Chronic stress shifts cortisol's normal rhythm (it should peak in the morning and fall at night), and the menopause transition itself nudges cortisol upward as estrogen declines, which can feed the classic 'wired and tired' pattern of daytime fatigue and 3am wakefulness. The fixes are largely behavioural: anchor your circadian rhythm, protect sleep, manage stress, train without overdoing it, and go easy on stimulants. A few supplements play a minor, caveated role.
Why it works▼
Morning light and a consistent wake time
Light and routine reinforce a healthy daily cortisol curve.
Tackle the 'wired and tired' pattern
Cortisol and sleep are a feedback loop; fixing the evening helps both.
Practise daily stress down-regulation
Reducing chronic stress is the most direct lever on cortisol.
Strength and walking over constant high intensity
Chronic over-training can keep cortisol elevated rather than help.
Reduce late caffeine and alcohol
Both disrupt the cortisol rhythm and the sleep that regulates it.
Cover magnesium and basics from food
These support stress physiology modestly; food comes first.
Address perimenopause with a clinician
The transition is medical territory; estrogen loss changes the whole picture.
- Women in or approaching perimenopause
- Anyone with the 'wired and tired' pattern
- People with high chronic stress
- Those wanting behaviour-first cortisol support
- 'Adrenal fatigue' is not a recognised medical diagnosis, and saliva or DUTCH cortisol panels are not validated to diagnose it; be cautious of protocols built on that framing, the behavioural steps here stand on their own
- Persistent fatigue, low mood, sleep or cycle changes deserve a doctor to check for thyroid problems, anaemia, depression and genuine adrenal disease (such as Addison's or Cushing's), which are real and treatable
- Adaptogens like ashwagandha and rhodiola have limited evidence and real cautions (ashwagandha has liver-injury reports and thyroid effects); they are optional, not core
- Perimenopause care, including whether hormone therapy is right for you, should be decided with a knowledgeable clinician
