Poor sleep patterns have been strongly linked to disrupted emotional experiences. Emotion regulation, defined as the capacity to manage one's own emotional responses, comprises strategies to increase, maintain, or decrease the intensity, duration, and trajectory of positive and negative emotions. Poor sleep has been identified as a risk factor for emotional dysregulation, but most of the focus has been on negative emotion regulation. We therefore asked whether natural variations in sleep are associated with the experience and regulation of both positive and negative emotion. Young adults, aged between 18-24 years (N = 101), completed 7 days of ecological momentary assessments using a smartphone application. Duration and quality of the previous night's sleep was reported each morning. Levels of positive and negative emotions, and strategies used to regulate emotions, were measured at pseudorandom timepoints four times a day. Multilevel modelling indicated that higher self-reported sleep quality was significantly associated with increased intensity and duration of positive emotion, and decreased intensity of negative emotion. There were no statistically significant associations between sleep duration and emotion intensity or duration. Sleep quality, and not sleep duration, was also associated with the reported use of positive emotion regulation strategies. For negative emotion regulation strategy use, we found no associations with sleep quality or duration. Naturally occurring fluctuations in daily sleep quality may be important for the experience and regulation of positive emotion in young adults. These findings emphasise the need to examine both positive and negative emotion, and emotion regulation to understand the links between sleep and mood.
睡眠质量差与情绪体验紊乱密切相关。情绪调节是指管理自身情绪反应的能力，包括增强、维持或降低积极和消极情绪的强度、持续时间和轨迹的策略。睡眠质量差已被确定为情绪失调的一个风险因素，但大多数研究都集中在消极情绪调节上。因此，我们想知道睡眠的自然变化是否与积极和消极情绪的体验和调节有关。年龄在 18-24 岁之间的年轻人（N=101）使用智能手机应用程序完成了 7 天的生态瞬间评估。每天早上报告前一晚的睡眠时间和质量。在每天四个随机时间点测量积极和消极情绪的水平以及用于调节情绪的策略。多层次模型表明，自我报告的睡眠质量越高，积极情绪的强度和持续时间增加，消极情绪的强度降低。睡眠时间与情绪强度或持续时间之间没有统计学上的显著关联。睡眠质量，而不是睡眠时间，与报告的积极情绪调节策略的使用有关。对于消极情绪调节策略的使用，我们没有发现睡眠质量或睡眠时间与它们之间存在关联。日常睡眠质量的自然波动可能对年轻人积极情绪的体验和调节很重要。这些发现强调了需要同时检查积极和消极情绪以及情绪调节，以了解睡眠和情绪之间的联系。
