BACKGROUND
Although past longitudinal research demonstrates that romantic partners affect one another's health outcomes, considerably less is known about how romantic experiences "get under the skin" in everyday life.
PURPOSE
The current study investigated whether young couples' naturally occurring feelings of closeness to and annoyance with each other during waking hours were associated with their overnight cardiovascular activity.
METHODS
Participants were 63 heterosexual young adult dating couples (Mage = 23.07). Using ecological momentary assessments, couples reported their hourly feelings of closeness to and annoyance with their partners across 1 day; subsequent overnight heart rate was captured through wearable electrocardiogram biosensors. Actor-partner interdependence models tested whether individuals' overnight heart rate varied as a function of (a) their own daytime feelings of closeness and annoyance (actor effects) and (b) their partner's daytime feelings of closeness and annoyance (partner effects) while controlling for daytime heart rate.
RESULTS
Although young adults' feelings of romantic closeness and annoyance were unrelated to their own overnight heart rate (i.e., no actor effects), gender-specific partner effects emerged. Young men's nocturnal heart rate was uniquely predicted by their female partner's daytime relationship feelings. When women felt closer to their partners during the day, men exhibited lower overnight heart rate. When women felt more annoyed with their partners during the day, men exhibited heightened overnight heart rate.
CONCLUSIONS
The findings illustrate gender-specific links between couple functioning and physiological arousal in the everyday lives of young dating couples, implicating physiological sensitivity to partner experiences as one potential pathway through which relationships affect health.
背景
尽管过去的纵向研究表明，恋爱伴侣会影响彼此的健康结果，但人们对恋爱经历如何在日常生活中“影响身体”知之甚少。
目的
本研究旨在探讨年轻夫妻在清醒时对彼此的亲近感和烦恼程度是否与他们的夜间心血管活动有关。
方法
参与者为 63 对异性年轻成年约会情侣（平均年龄=23.07 岁）。通过生态瞬时评估，情侣们在一天中每小时报告他们对伴侣的亲近感和烦恼程度；随后通过可穿戴心电图生物传感器记录他们夜间的心率。演员-伴侣相互依存模型检验了个体的夜间心率是否会随着（a）他们自己白天的亲近感和烦恼程度（演员效应）以及（b）他们伴侣白天的亲近感和烦恼程度（伴侣效应）而变化，同时控制了白天的心率。
结果
尽管年轻成年人的浪漫亲近感和烦恼感与他们自己的夜间心率无关（即没有演员效应），但出现了性别特定的伴侣效应。年轻男性的夜间心率仅由他们女性伴侣白天的关系感受预测。当女性白天对伴侣感觉更亲近时，男性的夜间心率就会降低。当女性白天对伴侣感到更烦恼时，男性的夜间心率就会升高。
结论
这些发现说明了年轻约会情侣日常生活中夫妻关系功能和生理唤醒之间的性别特定联系，表明对伴侣经历的生理敏感性可能是关系影响健康的途径之一。
