Nocturnal Command

Meaning

Nocturnal Command is a conceptual term representing the coordinated, neuroendocrine signaling cascade that is endogenously activated during the period of darkness and sleep to orchestrate critical recovery, repair, and anabolic processes. This command system is governed by the circadian master clock and is characterized by the peak secretion of restorative hormones, notably melatonin and growth hormone, and the nadir of the catabolic stress hormone cortisol. It dictates the physiological priority shift from daytime energy expenditure to nighttime regeneration and tissue maintenance.
