Which hormonal outcome occurs when disrupted sleep chronically elevates cortisol?

💡 Explanation

Disrupted sleep raises cortisol chronically, disturbing normal diurnal patterns, because the hypothalamic-pituitary-adrenal (HPA) axis drives hypercortisolism. An increased cortisol concentration desensitizes receptors, therefore feedback inhibition is stunted, rather than normal regulation of the ACTH hormone output.
