Sleep disorders happen more often in shift workers than day workers

Abstract

A total of 2198 nurses participated in the study, revealing that confusional arousal and nightmares are more common among those with rotational shift work schedules.

  • Nurses working two shift (day and evening) and three shift (day, evening, and night) schedules had an increased risk of confusional arousal compared to those working daytime only.
  • The odds ratios for confusional arousal were 2.10 for two shifts and 1.71 for three shifts.
  • Nurses on two and three shift schedules also faced an increased risk of nightmares, with odds ratios of 1.64 and 1.57, respectively.
  • No significant associations were found between other types of parasomnias and work schedules.
  • Working only night shifts was not linked to any of the parasomnias.
