Abstract

Night-shift nurses exhibited the lowest values of circadian rhythm amplitude, acrophase, autocorrelation, and mean of the circadian relative power.

  • Shift work is associated with adverse health outcomes.
  • Night-shift nurses displayed less robust circadian activity rhythms compared to those on day or evening shifts.
  • Evening-shift nurses showed greater variations in circadian activity rhythms than their day-shift counterparts.
  • Objective and subjective sleep quality may be affected by differing patterns of circadian activity rhythms in nurses.
