The Firefighter (FF) occupation leads to poor sleep quality and architecture. Disturbed sleep in these occupations can lead to poor outcomes including a series of chronic diseases and illnesses such as CVD. Purpose: The aims were 1) to quantify the sleep of this occupation and 2) compare it to age-matched normative data. Methods: 10 male FF completed3 nights of polysomnography recordings (Sleep ProfilerTM) in their own bed or barracks. A rmAnova was used to determine differences in sleep values and a Bonferroni correction with significance set at p<0.05. Results: Three important variables; deep sleep (FF: 2.7 +/-1.4 vs. 3.0 +/- 1.0 hrs), rapid eye movement (FF: 1.1 +/- 0.7 vs 1.1 +/- 0.5 hrs), and spindle duration (FF: 6.0 +/- 10.3 vs. 7.6 +/- 7.8 Hz.) for FF was statistically and/or clinically significant between sleep at home or in the barracks and between night and day shifts. All sleep results were significantly more deleterious when compared to normative data. Conclusions: These data demonstrate that firefighters show poor sleep quality and architecture. A firefighters’ decreased sleep quality and architecture may be due to their effects of sleep shift. These results, when compared to age-matched normative data show clinical manifestations of disturbed sleep in the FF populations.
