Abstract
Abstract
Introduction
Healthy sleep is vital for firefighter safety, health, wellness, and for public well-being. However, professional firefighters experience disturbed sleep at disproportionately high rates. The current study investigated whether firefighters can obtain healthy sleep by identifying (1) differences in sleep while “on-duty” and “off-duty” and (2) risk factors for poor sleep.
Methods
Professional firefighters in Richmond, Virginia’s Department of Fire and Emergency Services (N=268), reported their sleep using the Pittsburgh Sleep Quality Index (PSQI) both on- and off-duty. Good and poor sleepers were identified using the PSQI global score cutoff of 5. Demographic and STOP-BANG questionnaires were also completed.
Results
Using a repeated measures MANOVA, on-duty sleep was significantly worse compared to off-duty sleep across PSQI component and global scores F(7, 253)=45.24 p<.001, η²=.56. On-duty, 76.1% of firefighters were classified as poor sleepers compared to 42.9% off-duty. 34.7% were reclassified as good sleepers or stayed good sleepers (22.4%) when off-duty. A sizeable minority experienced consistently poor sleep while on- and off-duty (41.4%), and a small number reported worse sleep when off-duty (1.5%). More night calls and poorer self-rated mental health predicted worse on-duty sleep (p<.001) and poorer self-rated mental health predicted worse off-duty sleep (p<.001).
Conclusion
Healthy sleep is possible for professional firefighters. Almost a quarter of the sample was classified as “good sleepers” on-duty and over half were classified as “good sleepers” off-duty. Nonetheless, sleep on-duty was significantly worse overall, with over a third of the sample experiencing consistently poor sleep. When working a 24-hour variable shift schedule, it appears that poor sleep may “carryover” from on-duty to off-duty. Poorer self-rated mental health and more night calls were identified as risk factors. Further research is needed to probe risk and protective factors within this population.
