OBJECTIVE Experimental evidence suggests that inadequate sleep disrupts next-day affective processing and evokes greater stress reactivity. However, less research has focused on whether sleep predicts next-day affective reactivity to naturally occurring stressors and positive events in daily life, as well as the reversed direction of association (i.e., affective reactivity to daily events as predictors of subsequent sleep). The purpose of this study was to evaluate the within-person, bidirectional associations between nightly sleep duration and day-to-day fluctuations in affect related to stressors and positive events. METHOD Adults ages 33-84 (N = 1,982, 57% female) in the U.S. National Study of Daily Experiences II reported sociodemographics and chronic conditions at baseline, then completed telephone interviews for 8 consecutive days about their sleep duration, daily stressors, positive events, and affect. RESULTS Prior-night sleep duration moderated the link between current-day events and positive affect, but not negative affect. Specifically, nights of shorter-than-usual sleep duration predicted more pronounced decreases in positive affect in response to daily stressors, as well as smaller increases in positive affect in response to daily positive events. Results for the reversed direction of association showed no evidence for affective reactivity to daily events as predictors of subsequent sleep duration. People with more chronic conditions were more reactive to positive events, particularly after nights of longer sleep. CONCLUSION Affective reactivity to daily stressors and positive events vary based upon sleep duration, such that sleep loss may amplify loss of positive affect on days with stressors, as well as reduce positive affective responsiveness to positive events.

睡眠时间和对压力源的情感反应以及日常生活中的积极事件。

目的实验证据表明，睡眠不足会破坏第二天的情感处理，并引起更大的应激反应性。然而，较少的研究集中在睡眠是否能预测对自然发生的压力和日常生活中积极事件的第二天的情感反应，以及联想的相反方向（即对日常生活的情感反应，作为随后睡眠的预测指标）。这项研究的目的是评估夜间睡眠时间与压力源和阳性事件相关影响的日常波动之间的人际双向关联。方法在《美国国家每日经验研究II》中，年龄为33-84岁（N = 1,982，女性为57％）的成年人报告了基线的社会人口统计学和慢性病，然后连续8天完成电话访问，询问他们的睡眠时间，每日压力，积极事件和影响。结果前夜的睡眠时间减轻了当下事件与积极影响之间的联系，但没有消极影响。具体而言，比正常睡眠时间短的夜晚预测，对日常压力源的积极影响将明显降低，而对日常积极事件的积极影响则较小。反向关联的结果没有证据表明对日常事件的情感反应是随后睡眠时间的预测指标。慢性病多的人对阳性事件反应更强，尤其是在长夜睡眠之后。结论对日常应激源和阳性事件的情感反应随睡眠时间的长短而变化，因此睡眠丧失可能会增加应激源在几天内的积极影响，并降低对阳性事件的积极情感反应。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
