Le résumé fourni par la source

OBJECTIVE: This study seeks to better understand the impact of schedule change on physiological and self-report measures of stress and quality of life among career firefighters. METHODS: This study examined the impact of a schedule change from 24/48 to a 24-hour on/72-hour off, 48-hour on/72-hour off (i.e., 1/3/2/3) shift rotation on markers of stress among career firefighters over a 7-month period. Physiological measures such as salivary biomarkers (cortisol, testosterone, testosterone-to-cortisol ratio, interleukin-6) and blood pressure as well as self-reported survey instruments for occupational stress and job satisfaction were assessed throughout the study. RESULTS: By the end of the study, participants demonstrated significantly lower salivary cortisol concentrations, improved quality of life, and better sleep quality. CONCLUSIONS: These findings suggest that transitioning to a 1/3/2/3 schedule may reduce physiological stress and improve quality of life among career firefighters.
