Night Work

Meaning

Night Work, within the specific domain of hormonal health, refers to employment that requires individuals to be active predominantly during the conventional hours of darkness, a schedule that profoundly disrupts the natural circadian rhythm and the body’s essential sleep-wake cycle. This chronic misalignment between the internal biological clock and external environmental cues is a well-recognized, potent endocrine disruptor, severely impacting the necessary nocturnal secretion patterns of critical hormones like melatonin and cortisol. Clinically, this occupational exposure is strongly associated with a significantly increased risk of metabolic dysfunction, cardiovascular disease, and other chronic health issues.
