Despite extensive ties between sleep disruption, anger, and aggression, it is unclear whether sleep loss plays a causal role in shaping anger. On one hand, negative affect and distress frequently follow curtailed sleep, suggesting increased anger responses. On the other hand, fatigue and withdrawal also follow, potentially muting anger. To examine these competing possibilities, 142 community residents were randomly assigned to either maintain or restrict their sleep over 2 days. Before and after, these participants rated their anger and affect throughout a product-rating task alongside aversive noise. Sleep restriction universally intensified anger, reversing adaptation trends in which anger diminished with repeated exposure to noise. Negative affect followed similar patterns, and subjective sleepiness mediated most of the experimental effects on anger. These findings highlight important consequences of everyday sleep loss on anger and implicate sleepiness in dysregulation of anger and hedonic adaptation.

尽管睡眠障碍、愤怒和攻击之间存在广泛联系，但睡眠不足是否对愤怒的形成起着因果作用仍不清楚。一方面，负面情绪和痛苦经常伴随着睡眠不足，这表明愤怒反应增加了。另一方面，疲劳和退缩也随之而来，可能会抑制愤怒。为了检验这些相互竞争的可能性，142 名社区居民被随机分配在两天内保持或限制他们的睡眠。在此之前和之后，这些参与者在进行产品评价任务的同时，对他们的愤怒和情绪进行了评价，并伴随着不愉快的噪音。睡眠限制普遍加剧了愤怒，扭转了愤怒随着反复接触噪音而减弱的适应趋势。负面情绪也呈现出类似的模式，主观的困倦感介导了睡眠对愤怒的大部分实验影响。这些发现突出了日常睡眠不足对愤怒的重要影响，并暗示了困倦感在愤怒和享乐适应失调中的作用。（APA 心理学数据库记录（c），保留所有权利）。
