Hormonal Phase Shifting

Meaning

Hormonal Phase Shifting is the deliberate clinical adjustment of the timing of peak and trough secretion for specific endocrine factors relative to the 24-hour light-dark cycle or an individual’s habitual sleep-wake schedule. This sophisticated intervention is often medically necessary to correct a pathologically delayed or advanced hormonal phase, such as an inappropriately timed nocturnal melatonin release or a severely blunted morning cortisol awakening response. Successful shifting restores critical alignment between the body’s internal timing and the external environmental cues.
