Summary
Night shift work in police officers disrupts both central and peripheral circadian clocks, impairing hormonal rhythms and metabolic homeostasis including glucose and lipid regulation. These findings underscore the importance of lighting interventions and schedule design that minimize circadian misalignment in shift-working populations to reduce risks of obesity, diabetes, and hormonal imbalance.
Key Findings
- Circadian disruption from shift work is associated with reversed melatonin and cortisol rhythms, loss of clock gene rhythmicity, and impaired glucose and lipid homeostasis.
- Sleep disturbance linked to shift work is associated with obesity, insulin insensitivity, diabetes, hormonal imbalance, and appetite dysregulation.
- Hormones including growth hormone, melatonin, cortisol, leptin, and ghrelin are highly correlated with both sleep timing and intrinsic circadian rhythmicity, making them sensitive biomarkers of circadian disruption.
