This chapter offers an overview of the forgiveness and health connection. We offer a review of common ways to define forgiveness of others and self-forgiveness. Stress-and-coping theories of forgiveness of others and self-forgiveness are outlined. Both theories consider antecedents, correlates, and health outcomes of forgiveness of others and self-forgiveness and both offer a comprehensive and interpretive lens through which to view empirical research on associations between forgiveness of others and self-forgiveness with health outcomes. In reviewing 73 studies, we found seventy-five percent showed at least one connection between a dimension of forgiveness and a physical health outcome. We conclude by integrating and interpreting the research literature, identifying caveats and limitations, and offering a research agenda. Researchers and practitioners are encouraged to think broadly and model forgiveness-health relationships on established psychological and health theories and to execute theory-guided studies of the forgiveness and health connection.
