Night‑shift work harms health through circadian disruption, labor policies, and socioeconomic inequality

Extensive chronobiology research links disrupted melatonin secretion, altered cortisol rhythms, and impaired glucose metabolism to night‑shift exposure, increasing risks of obesity, diabetes, and cancer. Meta‑analyses confirm that rotating schedules exacerbate these effects compared with permanent night shifts. Scientific consensus also supports interventions like timed bright‑light exposure and strategic napping to mitigate harm.
Night‑shift work is not merely a personal health hazard but a symptom of entrenched economic structures that prioritize continuous production over human circadian integrity.
Historical precedents show that the current model was deliberately fashioned to allocate the most disruptive hours to low‑paid, marginalised workers, a pattern reinforced by neoliberal labour policies. Scientific evidence, Indigenous chronobiology, and cross‑cultural case studies converge on the need for regulated, circadian‑aligned scheduling, universal health safeguards, and a strategic shift toward automation. By amplifying marginalised voices and employing trickster insight to expose the absurdity of profit‑driven fatigue, policymakers can craft equitable solutions that protect health while reconfiguring the 24‑hour economy.
