Abstract：
In shift work disorder (SWD), disturbed sleep acutely impairs employees\' recovery, but little attention has been paid to sleep during longer recovery periods. We examined how holidays affect self-estimated sleep length, sleep debt, and recovery in cases of SWD. Twenty-one shift workers with questionnaire-based SWD and nine reference cases without SWD symptoms completed a questionnaire on recovery and sleep need. They also reported sleep length on two separate occasions: during a work period and after ≥ 2 weeks of holidays. Sleep debt was calculated by subtracting sleep length from sleep need. We used parametric tests to compare the groups and the periods. The groups reported shorter sleep on workdays than during holidays (median difference: SWD group 1.7 h, p<0.001; reference group 1.5 h; p<0.05). The SWD group\'s self-estimated sleep during holidays increased less above the sleep need (median 0.0 h) than the reference group\'s sleep (1.0 h, p<0.05). In addition, the SWD group reported good recovery from irregular working hours less often (14%) than the reference group (100%, p<0.001). Although holidays were generally associated with longer sleep estimates than workdays, employees with SWD experienced consistently less efficient recovery than those without SWD.
摘要：
在轮班工作障碍(SWD)中，睡眠受到干扰严重损害员工的康复，但是在较长的恢复期中很少注意睡眠。我们研究了假期如何影响自我估计的睡眠时间，睡眠债务，并在SWD的情况下恢复。21名具有基于问卷的SWD的轮班工人和9名没有SWD症状的参考案例完成了关于恢复和睡眠需求的问卷。他们还报告了两种不同情况下的睡眠时间：在工作期间和假期≥2周之后。睡眠债务是通过从睡眠需要中减去睡眠时间来计算的。我们使用参数检验来比较组和时期。各组报告工作日睡眠时间短于假期（中位数差异：SWD组1.7小时，p<0.001；参照组1.5h；p<0.05）。与参考组的睡眠(1.0h,p<0.05)。此外,社署组较参照组(100%,p<0.001)。尽管假期通常与比工作日更长的睡眠估计相关，社署雇员的恢复效率一直低于没有社署的雇员。
