Human bodies recognize at the molecular level that not all happiness is created equal, responding in ways that can help or hinder physical health, according to new research led by Barbara L. Fredrickson, Kenan Distinguished Professor of psychology in the College of Arts and Sciences at the University of North Carolina at Chapel Hill.
The sense of well-being derived from "a noble purpose" may provide cellular health benefits, whereas "simple self-gratification" may have negative effects, despite an overall perceived sense of happiness, researchers found. "A functional genomic perspective on human well-being" was published July 29 in Proceedings of the National Academy of Sciences.
"Philosophers have long distinguished two basic forms of well-being: a 'hedonic' [hee-DON-ic] form representing an individual's pleasurable experiences, and a deeper 'eudaimonic,' [u-DY-moh-nick] form that results from striving toward meaning and a noble purpose beyond simple self-gratification," wrote Fredrickson and her colleagues.
It's the difference, for example, between enjoying a good meal and feeling connected to a larger community through a service project, she said. Both give us a sense of happiness, but each is experienced very differently in the body's cells.
"We know from many studies that both forms of well-being are associated with improved physical and mental health, beyond the effects of reduced stress and depression," Fredrickson said. "But we have had less information on the biological bases for these relationships."
