Nocturnal Hormone Cycling

Meaning

Nocturnal Hormone Cycling describes the essential, programmed fluctuations in the secretion of various endocrine hormones that occur during the sleep period, primarily governed by the circadian rhythm and sleep architecture. This cycling includes the low point, or nadir, of cortisol, the pulsatile surge of Growth Hormone, and the rhythmic secretion of melatonin and prolactin. The integrity of this nightly hormonal symphony is absolutely critical for metabolic regulation, cellular repair, immune system consolidation, and overall physical and mental restoration. Disruptions to this cycle severely impair recovery.
