A long-acting adrenal hormone which regulates energy production, the immune system, brain chemistry, bone formation, muscle tone and libido.

A high cortisol to DHEA ratio has been linked to increased inflammation, suppressed immune function, hyperglycaemia, as well as impaired detoxification, skeletal health and cognitive function.

The cortisol awakening response (CAR) is a period of increased cortisol secretory activity initiated by morning awakening and typically peaking between 30 and 45min post awakening

A significant burst of cortisol in the immediate awakening period (within 20 min) followed by a steep decline in levels has been shown to be a better measure of CAR and health status.
