Suppose you hurt your knee while running. Further suppose that you want to make an appointment at Sports Medicine to address the issue. Is this selfish? There is a large difference between being selfish (absorbed with yourself at the expense of others) and engaging in self-care (attending to your needs without neglecting others’ needs). Forgiving is good self-care. Our research shows a cause-and-effect relationship between learning to forgive and improvement in heart health for cardiac patients:
Waltman, M.A., Russell, D.C., Coyle, C.T., Enright, R.D., Holter, A.C., & Swoboda, C. (2009). The effects of a forgiveness intervention on patients with coronary artery disease. Psychology and Health, 24, 11-27.
Our research shows a cause-and-effect relationship between learning to forgive and improvement in fibromyalgia symptoms:
Lee, Y-R & Enright, R.D. (2014) A forgiveness intervention for women with fibromyalgia who were abused in childhood: A pilot study. Spirituality in Clinical Practice, 1, 203-217. doi: 10.1037/scp0000025.
A recent meta-analysis showed a statistically significant correlation between degree of forgiveness and a host of different physical issues:
Lee, Y.R. & Enright, R.D. (2019): A meta-analysis of the association between forgiveness of others and physical health. Psychology & Health, 34, 626-643.
So, yes, forgiving does seem advantageous for one’s physical health.
