: Fire service shift workers are at risk of developing mental health difficulties related to sleep loss and emotion dysregulation. We aimed to clarify the relationship between off-shift recovery sleep and emotion regulation on stress, fatigue and irritability. : A total of 61 fire service shift workers (e.g. firefighter, captain, engineer, paramedic) on a "5/6" shift. : Following five 24-hour shifts, participants reported on emotion regulation as well as daily sleep, stress, fatigue and irritability during six consecutive off-shift recovery days. Mediation analyses examined (1) emotion regulation as a predictor and sleep as a mediator of stress, fatigue and irritability outcomes; and (2) sleep as a predictor and emotion regulation as a mediator of stress, fatigue and irritability outcomes. : Greater self-reported total sleep time predicted lower recovery stress, fatigue, and irritability. Greater subjective sleep efficiency predicted lower recovery stress and fatigue, but not irritability. No significant relationships emerged for objective sleep or emotion regulation variables predicting stress, fatigue or irritability. There were no significant findings with either emotion regulation or sleep variables included as mediators. : These findings suggest that stress management programs for fire service shift workers may be most effective when targeting sleep efficiency and quantity rather than emotion regulation strategies in the off-shift recovery period.
: 消防轮班工人由于睡眠不足和情绪失调，存在出现心理健康问题的风险。本研究旨在明确轮班后恢复性睡眠与情绪调节对压力、疲劳和易怒的关系。: 共有 61 名消防轮班工人（如消防员、队长、工程师、护理人员）参加了“5/6”班制。: 在五个 24 小时的轮班后，参与者在六个连续的轮班后恢复日报告了情绪调节以及日常睡眠、压力、疲劳和易怒情况。中介分析检验了（1）情绪调节作为压力、疲劳和易怒结果的预测因素，以及睡眠作为中介因素；（2）睡眠作为压力、疲劳和易怒结果的预测因素，以及情绪调节作为中介因素。: 自我报告的总睡眠时间越长，恢复性压力、疲劳和易怒程度越低。主观睡眠效率越高，恢复性压力和疲劳越低，但对易怒无显著影响。客观睡眠或情绪调节变量对压力、疲劳或易怒的预测均无显著关系。无论是情绪调节还是睡眠变量作为中介变量，均未发现显著结果。: 这些研究结果表明，针对消防轮班工人，在轮班后恢复期间，睡眠效率和睡眠量可能比情绪调节策略更能有效管理压力。
