Sleep is an important process that can influence and be influenced by daily events and emotions. We examined the bidirectional relationships between sleep, daily events, and emotions with a daily diary method completed by 181 mothers ( = 41.91, = 5.06). They answered morning and evening questionnaires for 1 week at three different points in time separated by nine months each, 21 days in total. Measures of sleep quality and emotional experiences each morning were assessed, and they reported on their best and worst experience of the day, peak emotional responses to these events, and affect in the evening. Sleep behavior, including total sleep time and sleep efficiency, was objectively quantified using wrist actigraphy. Multilevel modeling analyses showed that longer sleep duration and better subjective quality predicted greater positive emotions and lower negative emotions upon waking, and lower levels of peak perceived stressfulness, but not peak positivity ratings. Daily experiences did not predict sleep duration. Conversely, negative affect in the evening and greater peak perceived stressfulness during the day predicted worse sleep quality that night, whereas positive affect and positive events were not related to sleep. Although correlational, these findings suggest that good sleep can improve waking affect and help mitigate the impact of stressful experiences but does not amplify responses to the positive events of the day. In turn, daily perceived stress reactivity impairs sleep quality. These novel findings show stronger bidirectional relationships between sleep with daily stress, than sleep with daily positivity.

睡眠是一个重要的过程，它会受到日常事件和情绪的影响，同时也会对其产生影响。我们采用每日日记法，对181名母亲（平均年龄 = 41.91岁，标准差 = 5.06）进行了研究，以探讨睡眠、日常事件和情绪之间的双向关系。她们在三个不同时间点，每隔九个月，连续一周每天早晚填写问卷，共21天。每天早晨评估睡眠质量和情绪体验，并报告当天最好和最糟的经历、对这些事件的峰值情绪反应以及晚上的情绪状态。使用手腕活动记录仪客观量化睡眠行为，包括总睡眠时间和睡眠效率。多层次建模分析表明，较长的睡眠时间和较好的主观睡眠质量预示着醒来时会有更积极的情绪、更低的消极情绪，以及更低水平的峰值感知压力，但与峰值积极评价无关。日常经历并不能预测睡眠时间。相反，晚上的消极情绪和白天更高的峰值感知压力预示着当晚睡眠质量更差，而积极情绪和积极事件与睡眠无关。尽管这些结果是相关性的，但表明良好的睡眠可以改善清醒时的情绪，有助于减轻压力经历的影响，但不会增强对当天积极事件的反应。反过来，日常感知的压力反应性会损害睡眠质量。这些新发现表明，睡眠与日常压力之间的双向关系比睡眠与日常积极情绪之间的双向关系更强。
