Growing evidence suggests that physical warmth and social warmth-feeling socially connected to others-are linked. In particular, thermoregulatory systems that maintain a relatively warm internal body temperature may also support feelings of social connection. However, it is unknown whether and how feelings of physical and social warmth fluctuate together across time in daily life. To this end, the current study examined tympanic temperature, a measure of internal body temperature, and feelings of social connection assessed multiple times a day over 1 week. Consistent with hypotheses, moment-to-moment changes in tympanic temperature covaried with feelings of social connection across assessments. Thus, warmer body temperatures, in the nonfebrile range, were associated with greater feelings of social connection, and cooler body temperatures were associated with lower feelings of social connection. These findings provide further evidence for the link between physical and social warmth and contribute to an understanding of the dynamic fluctuation of affective experience across time.

身体和社交的温暖：每天体温升高与社交联系的感觉增强有关。

越来越多的证据表明，身体上的温暖和社交上与他人之间的社交联系是相互联系的。特别地，维持相对温暖的内部体温的体温调节系统也可以支持社交联系的感觉。然而，未知的是，在日常生活中，身体和社会温暖的感觉是否以及如何随时间一起波动。为此，当前的研究检查了鼓膜温度，一种内部体温的测量方法以及在一周内每天多次评估的社交联系感。与假设一致，鼓室温度的瞬时变化与评估之间的社会联系感相关。因此，在非发烧范围内，体温升高会带来更大的社交联系感，较低的体温与较低的社交联系感相关。这些发现为身体和社会温暖之间的联系提供了进一步的证据，并有助于理解情感体验随时间的动态波动。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
