As compared to negative affect, only a small number of studies have examined influences of positive affect on cardiovascular stress responses, of which only a few were concerned with cardiovascular recovery. In this study, heart rate, low- and high-frequency heart rate variability, blood pressure, and levels of subjectively experienced stress were obtained in 65 students before, during and after exposure to academic stress in an ecologically valid setting. Higher trait positive affect was associated with more complete cardiovascular and subjective post-stress recovery. This effect was independent of negative affect and of affective state during anticipation of the stressor. In contrast, a more positive affective state during anticipation of the challenge was related to poor post-stress recovery. The findings suggest that a temporally stable positive affect disposition may be related to adaptive responses, whereas positive emotional states in the context of stressful events can also contribute to prolonged post-stress recovery.
与负性情绪相比，仅有少数研究探讨了正性情绪对心血管应激反应的影响，其中只有少数研究关注心血管恢复。在这项研究中，我们在生态有效的环境中，在 65 名学生暴露于学业压力之前、期间和之后，获取了心率、低频和高频心率变异性、血压和个体经历的压力水平。较高的特质正性情绪与更完全的心血管和主观应激后恢复相关。这种效应独立于负性情绪和应激源预期时的情感状态。相反，在应激源预期时更积极的情感状态与应激后恢复不良相关。这些发现表明，暂时稳定的正性情绪倾向可能与适应性反应有关，而在应激事件背景下的积极情绪状态也可能促进应激后恢复的延长。
