发表于《美国科学院学刊》的研究报告指出，人际关系对身体健康的影响不容小视，特别是在心脏病、高血压、癌症的发病率上，其作用甚至不亚于饮食和休息。
美国加州大学洛杉矶分校医学院科学家进行的这项新研究发现，人际关系处不好可能导致身体炎症恶化，进而引发一系列疾病，如心脏病、高血压、癌症等。研究人员通过对122名健康的年轻人进行跟踪观察研究，并根据他们的日记来判断其心情状态和周边人际关系后发现，保持积极向上的心态，周围人能跟自己相处良好且没有竞争关系的状态，更容易让人保持身体健康，避免生病。
Negative and competitive social interactions are related to heightened proinflammatory cytokine activity

Research has consistently documented that social relationships influence physical health, a link that may implicate systemic inflammation. We examined whether daily social interactions predict levels of proinflammatory cytokines IL-6 and the soluble receptor for tumor necrosis factor-α (sTNFαRII) and their reactivity to a social stressor. One-hundred twenty-two healthy young adults completed daily diaries for 8 d that assessed positive, negative, and competitive social interactions. Participants then engaged in laboratory stress challenges, and IL-6 and sTNFαRII were collected at baseline and at 25- and 80-min poststressor, from oral mucosal transudate. Negative social interactions predicted elevated sTNFαRII at baseline, and IL-6 and sTNFαRII 25-min poststressor, as well as total output of sTNFαRII. Competitive social interactions predicted elevated baseline levels of IL-6 and sTNFαRII and total output of both cytokines. These findings suggest that daily social interactions that are negative and competitive are associated prospectively with heightened proinflammatory cytokine activity.
