Support-Giving Is Associated With Lower Systemic Inflammation.

Support-giving behavior and health are linked such that more support-giving is related to better health and longevity for the person giving. How such a link occurs, however, is an open question for research. Two cross-sectional studies test the hypothesis that support-giving behavior relates to lower systemic inflammation, a potential biological pathway linking supportive behavior with health. Results of Study 1 show that giving to more social targets (to family and friends, and also volunteering) is associated with lower inflammation. Receiving support was not associated with inflammation. In a replication and extension, Study 2 shows that a greater frequency of giving is also related to lower systemic inflammation, over and above the size of one's social network and individual differences in reporting socially desirable responses. Although more research is needed to establish whether support-giving causes systemic inflammation to change, the current findings highlight a promising pathway by which support-giving behavior benefits health.
