Cortisol and burnout
Can't get up in the morning, can't fall asleep at night — when the stress axis fails
Morning fatigue and evening wired-ness aren't "laziness." They are signs of a disrupted cortisol rhythm — a burned-out stress axis that can be objectively measured from saliva.
In the morning you need coffee just to get up. Energy fluctuates through the day. In the evening you're physically exhausted, but your mind won't shut off. This has gone on for years. Maybe you've heard of "adrenal fatigue" or "chronic stress" — but no one has actually run a specific test. Yet one exists — a salivary cortisol test, which takes samples four times a day and shows the exact curve of your stress axis.
Does this sound familiar?
If this sounds like you, keep reading.
- you can't get going in the morning without caffeine or sugar
- you're tired in the evening, but your mind won't switch off
- energy fluctuates throughout the day
- it takes you days or weeks to recover from stress
- everything got worse after a major stressful event or loss.
What a healthy cortisol curve should look like
Cortisol is the main stress hormone produced by the adrenal glands. Its level should follow a clear daily curve:
Morning (about 30 minutes after waking): high — this is the so-called cortisol awakening response, which switches you on and helps you get up.
During the day: gradually declines.
Evening (around 10 pm): low — allowing the body to shift into night mode and fall asleep.
When the rhythm is disrupted, the curve is inverted — cortisol is low in the morning (which is why you feel a morning slump) and paradoxically rises in the evening (which is why you can't fall asleep).
The test that captures this objectively
The salivary cortisol test measures free cortisol across 4 samples during the day: on waking, mid-morning, afternoon, and evening. These points plot a curve that shows the exact state of your stress axis.
The test is done at home — samples are collected using test swabs sent to you by mail. The result is more objective than a standard blood cortisol measurement, which only captures a single moment in time.
What to do after getting your results
With a disrupted curve, the main strategy is restoring your daily rhythm — sleep hygiene, morning light exposure, avoiding blue light in the evening. Alongside this, targeted adrenal support (adaptogens, or possibly adrenal cortex extract) can be added, set individually depending on whether morning fatigue or evening insomnia dominates.
Specific products and dosing are handled in the Consultation with a Doctor / Therapist (€149) — with a disrupted stress axis, individualization is key: some people need morning stimulation, others evening calming support.
In pyroluria, the cortisol rhythm is often disrupted secondarily — in that case it makes sense to test for pyroluria first and add cortisol as a supplementary test.
