Objective

This study examined whether recalling a social stress that evoked lonely feelings produces greater affective and blood pressure responses than recalling non-social stress or a relaxing event.

Methods

Young adults (n = 114) underwent one of three inductions: recalling a social stressor in which one felt lonely, recalling a non-social non-lonely stressor, and relaxation. Negative affect was assessed during baseline, induction, and recovery. Blood pressure was assessed continuously using a finger cuff.

Results

Both the lonely and non-lonely stress conditions reported increased negative affect following the induction, with neither condition having fully recovered to baseline levels by the end of the study. For blood pressure, during recovery, blood pressure increased linearly for the lonely stress condition, but remained steady for the other conditions.

Conclusions

Recalling a social stress evoking lonely feelings may be more harmful for cardiovascular health than recalling non-social stressors. Results extend work demonstrating that in vivo stressors involving social evaluation elicit larger stress responses compared to stressors without this component.

所有孤独的人：比较孤独作为社交压力源与非孤独压力对血压恢复的影响

客观的

这项研究检验了回忆引起孤独感的社会压力是否比回忆非社会压力或放松的事件会产生更大的情感和血压反应。

方法

年轻人（n  = 114）经历了以下三种诱导之一：回忆一种感到孤独的社交压力源，回忆一种非社交的非孤独压力源，以及放松。在基线、诱导和恢复期间评估负面影响。使用指套连续评估血压。

结果

在诱导后，孤独和非孤独的压力条件都报告了增加的负面影响，到研究结束时，这两种条件都没有完全恢复到基线水平。对于血压，在恢复期间，孤独压力条件下的血压线性增加，但其他条件下保持稳定。

结论

回忆起引发孤独感的社会压力可能比回忆非社会压力更有害于心血管健康。结果扩展了工作，证明与没有该成分的压力源相比，涉及社会评价的体内压力源会引起更大的压力反应。
