Prior research indicates that chronic stress increases allostatic load and alters individuals’ affective response to stress. Recent studies have linked health-related behaviours including poor sleep and physical inactivity with elevated negative affect responses to stress. This study extends prior work to investigate chronic stress experience, sleep, and physical activity as predictors of negative affect and acute stress experience during acute, sustained naturalistic stress.

慢性压力体验、睡眠和身体活动：与负面情绪变化和对自然压力源的急性压力反应的关系

先前的研究表明，慢性压力会增加压力负荷并改变个体对压力的情感反应。最近的研究将包括睡眠不足和缺乏身体活动在内的健康相关行为与对压力的负面影响反应升高联系起来。这项研究扩展了先前的工作，以调查慢性压力体验、睡眠和身体活动作为急性、持续自然压力期间负面影响和急性压力体验的预测因子。
