Nocturnal Gene Expression

Meaning

Nocturnal Gene Expression refers to the specific, time-gated pattern of genetic transcription and translation that occurs predominantly and robustly during the sleep phase, driven by the body’s intrinsic circadian rhythm and the corresponding nocturnal hormonal milieu. This expression profile is fundamentally crucial for initiating and completing restorative processes, including DNA repair, widespread protein synthesis, memory consolidation, and the essential pulsatile release of key anabolic hormones like growth hormone. Disruption of this precise nocturnal genetic code severely impairs systemic repair and accelerates the biological rate of aging.
