有限的研究已经解决了宠物形式的社会支持如何影响交感神经和下丘脑-垂体-肾上腺对心理挑战的反应。本研究考察了社会支持对唾液皮质醇和心率（HR）的影响。48名参与者被随机分配到三种不同的情况下（人类朋友、新狗或对照组）。所有参与者都完成了特里尔社会压力测试，并提供了皮质醇、人力资源和状态-特质焦虑量表测量。对于与狗配对的参与者，总体皮质醇水平在整个实验过程中减弱，HR在特里尔社会压力测试中减弱。对于所有组来说，在特里尔社会压力测试后，状态焦虑增加，而在特里尔社会压力测试期间的HR是皮质醇的预测因子。这些结果表明，在不熟悉的环境中短期接触一只陌生的狗可能是有益的。他们还提出了与宠物有关的有益作用的可能机制。
Limited research has addressed how social support in the form of a pet can affect both sympathetic and hypothalamic-pituitary-adrenal reactivity in response to a psychological challenge. The present study examined the effects of social support on salivary cortisol and heart rate (HR). Forty-eight participants were randomly assigned to three different conditions (human friend, novel dog, or control). All participants completed the Trier Social Stress Test and provided cortisol, HR, and State-Trait Anxiety Inventory measures. For participants paired with a dog, overall cortisol levels were attenuated throughout the experimental procedure, and HR was attenuated during the Trier Social Stress Test. For all groups, state anxiety increased after the Trier Social Stress Test, and HR during the Trier Social Stress Test was a predictor of cortisol. These results suggest that short-term exposure to a novel dog in an unfamiliar setting can be beneficial. They also suggest a possible mechanism for the beneficial effect associated with affiliation with pets.
