Night Shift Hormones

Meaning

Night shift hormones is a clinical and conceptual term referring to the suite of endocrine messengers whose synthesis and secretion are predominantly upregulated during the nocturnal period of rest and darkness, orchestrating crucial repair, regeneration, and metabolic processes. These hormones, notably melatonin, growth hormone (GH), and prolactin, play vital roles in cellular cleanup, tissue repair, fat metabolism, and immune modulation. The proper, rhythmic secretion of these hormones is essential for maintaining circadian rhythm, metabolic health, and long-term longevity. Disruption of this nocturnal hormonal pattern compromises systemic recovery.
