The current study asked a sample (N = 20) of healthy young adults to report their daily hugging behaviors over a 14-day period and to collect their saliva at the beginning and end of the study. Based on affection exchange theory, we hypothesized that the frequency of hugging would be inversely related to proinflammatory cytokines, including interleukins (IL) 1-β, 6, and 8, and tumor necrosis factor-alpha (TNF-α). Controlling for baseline levels, hugging was significantly and inversely related to IL1-β and TNF-α after the 14-day period. Associations with IL-6 and IL-8, although nonsignificant, were also in the hypothesized direction.

每日拥抱预测两种促炎细胞因子的水平较低

当前的研究要求健康的年轻人样本 ( N = 20) 报告他们在 14 天内的日常拥抱行为，并在研究开始和结束时收集他们的唾液。基于情感交换理论，我们假设拥抱的频率与促炎细胞因子呈负相关，包括白细胞介素 (IL) 1-β、6 和 8，以及肿瘤坏死因子-α (TNF-α)。控制基线水平，14 天后拥抱与 IL1-β 和 TNF-α 显着负相关。与 IL-6 和 IL-8 的关联虽然不显着，但也在假设的方向上。
