This study aimed to investigate the role of sleep physiology in recovery from burnout, in particular the relation between sleep and changes in fatigue and whether those changes would be related to return to work. 23 white-collar workers on long-term sick leave (>3 months) due to a burnout related diagnosis and 16 healthy controls were subjected to polysomnographic recordings at baseline and after 6-12 months' rehabilitation. Occupational status, subjective sleep quality, fatigue, anxiety and depression were assessed. Recovery from burnout was accompanied by improved sleep continuity. Significant interaction effects were seen for number of arousals, sleep fragmentation, sleep latency, sleep efficiency and time of rising. The burnout group improved significantly on all symptom variables although the post-treatment levels did not reach the levels of the controls. Recovery from fatigue was related to a reduction of the arousal from sleep and was the best predictor of return to work.
本研究旨在调查睡眠生理在倦怠恢复中的作用，特别是睡眠与疲劳变化之间的关系，以及这些变化是否与重返工作岗位有关。23名因倦怠相关诊断而长期病假（超过3个月）的白领工人和16名健康对照者在基线时以及6至12个月康复后接受了多导睡眠图记录。评估了职业状况、主观睡眠质量、疲劳、焦虑和抑郁情况。倦怠的恢复伴随着睡眠连续性的改善。在觉醒次数、睡眠碎片化、睡眠潜伏期、睡眠效率和起床时间方面观察到显著的交互作用。尽管治疗后的水平未达到对照组的水平，但倦怠组在所有症状变量上均有显著改善。疲劳的恢复与睡眠觉醒的减少有关，并且是重返工作岗位的最佳预测指标。
