The present study investigated whether the presence of a romantic partner in daily life is associated with attenuated sympathetic nervous system responses. Additionally, romantic attachment style was tested as a moderator. For one day, 106 heterosexual young adult dating couples wore ambulatory sensors that monitored electrodermal activity (EDA) – an index of sympathetic arousal. Couples reported whether they were together or apart for every hour of the data collection day. Men and women exhibited lower EDA during hours in which their partner was present compared to hours in which they were absent. Additionally, romantic attachment style moderated this association; those who had low anxious attachment showed a stronger attenuating effect of partner presence compared to those with higher anxious attachment. Similarly, those who had low avoidant attachment showed heightened effects of partner presence compared to those with higher avoidant attachment. Romantic partner presence may facilitate everyday health-promoting physiological processes.

本研究调查了日常生活中浪漫伴侣的存在是否与交感神经系统反应减弱有关。此外，浪漫依恋风格作为主持人进行了测试。一天，106 对异性恋年轻成人约会夫妇佩戴动态传感器监测皮肤电活动 (EDA)——一种交感神经唤醒指数。夫妻报告他们在数据收集日的每个小时是在一起还是分开。与伴侣不在场的时间相比，男性和女性在伴侣在场的时间里表现出较低的 EDA。此外，浪漫的依恋风格缓和了这种联系；与那些焦虑依恋程度较高的人相比，那些焦虑依恋程度较低的人表现出更强的伴侣在场衰减效应。相似地，与回避依恋较高的人相比，回避依恋较低的人表现出伴侣在场的影响更大。浪漫伴侣的存在可能会促进日常促进健康的生理过程。
