Psychosocial stress is widespread worldwide and particularly affects young adults. There is a close and bidirectional relationship between sleep quality and mental health. Sleep duration, which is an important feature of sleep quality, shows both intra-individual variations and inter-individual differences. Internal clocks control individual sleep timing, which, in turn, defines the chronotype. On workdays, however, the end and duration of sleep are largely limited by external factors, such as alarm clocks, especially in later chronotypes. The aim of this study is to investigate whether there is a relationship between sleep timing and duration on workdays and measures for psychosocial stress, such as anxiety and depression; subjective workload; and the subjective impact of a high workload on sleep. We used a combination of Fitbit wearable actigraphy data and a questionnaire survey of young, healthy medical students and calculated correlations between the respective variables. We found that a shorter sleep duration on workdays is associated with a higher subjective workload and a higher subjective impact of a high workload on sleep, which, in turn, are associated with higher measures of anxiety and depression. Our study contributes to understanding the importance of sleep timing/duration and their regularity on weekdays for subjectively perceived psychosocial stress.
心理社会压力在全球范围内普遍存在，尤其影响年轻人。睡眠质量与心理健康之间存在密切的双向关系。睡眠时间作为睡眠质量的一个重要特征，既存在个体内部差异，也存在个体间差异。生物钟控制个体的睡眠时间，而睡眠时间又反过来定义了生物钟类型。然而，在工作日，睡眠的结束时间和时长在很大程度上受到外部因素的限制，比如闹钟，尤其是对于生物钟类型较晚的人来说。本研究的目的是调查工作日的睡眠时间和时长与心理社会压力指标（如焦虑和抑郁）、主观工作量以及高工作量对睡眠的主观影响之间是否存在关联。我们结合了Fitbit可穿戴设备的活动记录数据以及对年轻健康医学生的问卷调查，并计算了各变量之间的相关性。我们发现，工作日较短的睡眠时间与较高的主观工作量以及高工作量对睡眠的较高主观影响相关，而这又与更高的焦虑和抑郁指标相关。我们的研究有助于理解工作日的睡眠时间/时长及其规律性对于主观感受到的心理社会压力的重要性。
