CORTISOL
Additional Information
Diurnal Cortisol Curve Assessment
Thirty minutes after awakening from a good night’s sleep, cortisol levels are at the highest they’ll be all day. Following the morning peak, cortisol levels then fall to less than half that peak level by noon. They continue to drop to very low levels at night where they stay low during the sleep hours. Some individuals have a sharp rise to reach morning levels, others a more gradual incline. Looking at cortisol levels graphed during the day, any abnormal elevation, or depression of levels, or a loss of the expected curve with its characteristic morning peak and swooping decline towards evening may suggest HPA (hypothalamus-pituitary-adrenal) axis dysfunction – which is what we’re most interested in assessing when we’re looking at a diurnal cortisol curve.
