Although meeting close friends through video calls has become common, less is known about its stress-buffering effect. This study aims to examine whether cardiovascular responses to stress are decreased when the presence of a friend on a monitor compared to the presence of a friend in person or alone. Forty-six undergraduate students completed a stress task while in the room with a friend (1) in person (in-person condition), (2) on Zoom (online condition), or (3) alone (alone condition). Blood pressure and heart rate were monitored throughout the experiment. Analyses revealed that diastolic blood pressure after the stress was recovered closer to the pre-stress state under in-person and online conditions than alone condition. However, the study observed no differences across groups regarding self-reported affect. In summary, this result suggests that even the online presence of a friend, as well as in-person friends, may help recover blood pressure to the original state without one's awareness.
尽管通过视频通话结识亲密朋友已变得很常见，但人们对其压力缓冲作用却知之甚少。本研究旨在探讨与朋友亲自在场或独自一人相比，当朋友出现在屏幕上时，对应激的心血管反应是否会降低。46名本科生在与朋友共处一室的情况下完成了一项应激任务：（1）朋友亲自在场（面对面条件），（2）通过Zoom视频通话（在线条件），或（3）独自一人（单独条件）。在整个实验过程中监测血压和心率。分析表明，与单独条件相比，在面对面和在线条件下，应激后的舒张压恢复到更接近应激前状态。然而，该研究在自我报告的情感方面未观察到组间差异。总之，这一结果表明，即使朋友只是在线出现，以及朋友亲自在场，都可能在人们未意识到的情况下帮助血压恢复到原始状态。
