“Forgiveness: Spiritual and Medical Implications” by Christina Puchalski, MD.
“On a societal level, we face social injustice, urban crime, terrorist acts and war. These realities of society can also lead to resentment, territorialism and hatred. While many of these aspects of our society are wrong and perhaps even warrant a justifiable anger and hatred until we can forgive even the most horrendous of these acts, how can we as a society, or as a civilization, live together in peace? Thus, forgiveness is the basic building block of a tolerant society.
There have been many studies looking at the role of forgiveness in health. Unforgiving persons have increased anxiety symptoms, increased paranoia, increased narcissism, increased frequency of psycho-somatic complications, increased incidence of heart disease and less resistance to physical illness. Others have found that people who are unable to forgive themselves or others also have an increased incidence of depression and callousness toward others. The act of forgiveness can result in less anxiety and depression, better health outcomes, increased coping with stress, and increased closeness to God and others.
There have been numerous studies looking at forgiveness interventions. The interventions involved counseling and exercises which were used to help people move from anger and resentment towards forgiveness. In one study, incest survivors who experienced the forgiveness intervention had at the end of the intervention increased abilities to forgive others, increased hopefulness and decreased levels of anxiety and depression. In another study, college students were randomized to a group that received a forgiveness education program and another group who studied human relations. The group that received the forgiveness education program showed higher levels of hope and an increased willingness to forgive others. This greater self-forgiveness was associated with increased self-esteem, lower levels of anxiety, lower levels of depression and a more positive view of their patient.
In many of these studies, it was shown that people who are able to forgive are more likely to have better interpersonal functioning and therefore social support. In terms of social support, there is a large body of literature that demonstrated the value of social support. Social support has been shown to reduce cardiovascular risks, promote faster recovery and increased survival rates from several types of cancer. Therefore, forgiveness, since it improved interpersonal functioning, might mediate these better health outcomes through the ability of people to have increased social support.
Thus, act of forgiving from a research end seems to indicate that forgiveness can improve personal, interpersonal, and societal well-being.”
