Sleepiness and sleep problems in Italian police officers working shifts

Circadian Biology Weekly Brief ↗PubMed ↗

Updated Mar 31, 2026

Abstract

The occurrence of sleep-related accidents was significantly increased in shift workers, with 35.7% of them exhibiting sleep disorders.

Sleep disorders were present in 35.7% of shift workers and 26.3% of non-shift workers.
Shift-work conditions and seniority may contribute to an increased likelihood of sleep disorders.
No significant difference was found in sleepiness scores between shift workers and non-shift workers.
Indicators of sleep disorders were related to the increased occurrence of sleep-related accidents in shift workers.
Stressful work conditions could lead to an underestimation of sleepiness or may counteract sleepiness.
