Although stress is an everyday fact of life, it can lead to poor health outcomes, particularly when intense or prolonged. However, humans have unique cognitive abilities and thus may be able to combat stress by engaging critical psychological defence mechanisms. In this review, we discuss the field of mind‐body medicine, which focuses on improving our understanding of the mechanisms underlying this response and developing interventions that might be used to limit the effects of chronic stress. We review the findings of past and current research in this field that has focused on the impact of psychological, emotional, and behavioural factors, including love, social connectedness, and happiness on human health and the amelioration of pain as well as other signs and symptoms of disease. While these studies have not yet led to confirmed, quantifiable conclusions, the overall weight of evidence suggests that happiness (defined as a personal sense of well‐being) may be directly associated with improved health parameters and reductions in debilitating symptoms. Collectively, these findings suggest that interventions designed to promote stress mitigation, notably those that encourage social activity, may lead to significant improvements in human health.

身心医学的基础：爱、良好的关系和幸福可以调节压力并促进健康

尽管压力是日常生活中的一个事实，但它可能会导致不良的健康结果，特别是当压力强烈或持续时间较长时。然而，人类具有独特的认知能力，因此可能能够通过关键的心理防御机制来对抗压力。在这篇综述中，我们讨论了身心医学领域，重点是提高我们对这种反应背后机制的理解，并开发可用于限制慢性压力影响的干预措施。我们回顾了该领域过去和当前的研究结果，重点关注心理、情感和行为因素（包括爱、社会联系和幸福感）对人类健康的影响以及疼痛以及其他体征和症状的改善的疾病。虽然这些研究尚未得出确认的、可量化的结论，但总体证据表明，幸福感（定义为个人幸福感）可能与健康参数的改善和衰弱症状的减少直接相关。总的来说，这些研究结果表明，旨在促进缓解压力的干预措施，特别是那些鼓励社交活动的干预措施，可能会显着改善人类健康。
