Nighttime Urban Noise May Disturb Body Clocks and Hormone Health in Shift Workers

AI simplified

Abstract

Nighttime noise and rotating night duties shifted melatonin timing and reduced sleep continuity.

  • Exposure to nighttime noise is associated with altered circadian rhythms and disrupted sleep patterns.
  • Groups exposed to nighttime work exhibited increased fasting glucose and decreased insulin sensitivity.
  • Unfavorable lipid profiles were noted among individuals working rotating night shifts.
  • Long-term night-duty workers may experience an increase in cardiometabolic load.
  • A conceptual model suggests that repeated exposure to these conditions could lead to cumulative circadian and metabolic changes.
