The study, titled, “Daily positive events and inflammation: Findings from the National Study of Daily Experiences,” suggests that positive aspects of everyday life may accumulate over time to protect against inflammation and promote long-term health. “In this study, we found that daily positive events were associated with lower levels of inflammation,” researcher Nancy Sin said. “Previous research has shown that negative psychological states, such as stress and depression, are linked to elevated inflammation, which increases the risk of chronic diseases and death. We were interested in whether daily experiences of positive events could protect against inflammation.” Nancy Sin is a postdoctoral fellow in the Center for Healthy Aging and the department of biobehavioral health; other researchers on the study include Jennifer Graham-Engeland, associate professor of biobehavioral health, and David Almeida, professor of human development and family studies.
