What is The Cortisol Awakening Response?
Cortisol provides the boost we require in the morning which prepares us for the day ahead. The Cortisol Awakening Response is the rise in cortisol levels observed at 30 minutes post-awakening (approximately 35-60% above the waking value) followed by an expected decline one hour after waking. The behaviour of cortisol is an important physiological response to anticipation of the day ahead and is a key indicator of central stress response system health. The waking, 30 minute, and 60 minute cortisol results comprise what has been referred to as a mini stress test*.

Why Test the Anticipated Morning Cortisol Behaviour?
Checking the precise dynamics of morning cortisol secretion is important if you suspect that the cortisol awakening response (CAR) is not occurring properly.
Slight cortisol irregularity can often be corrected by changes to lifestyle and diet. A re-balanced cortisol output, synchronised with the day / night cycle, will allow for other hormones to flourish as the body’s hormonal balance is restored.
More serious cortisol irregularity should be followed up with your GP or other suitably qualified health practitioner.
