Eudaimonic Happiness

In their never-ending search for the best way to live, Greek philosophers argued over the relative benefits of hedonic and eudaimonic happiness. Hedonic well-being sees happiness as a factor of increased pleasure and decreased pain, while eudaimonic ("human flourishing") happiness has more to do with having a larger purpose or meaning in life. A recent study from University of North Carolina at Chapel Hill psychologist Barbara Fredrickson may reveal which form of happiness is more beneficial for health and well-being.
The study, which was published in the Proceedings of the National Academy of Sciences last year, found that while both types of happiness can make you feel good, the latter could promote physical health and longevity as well. Using phone interviews, questionnaires and blood samples, the study explored how the two forms of happiness affected individuals on a genetic level. Participants with more hedonic and less eudaimonic well-being were found to have a lower production of virus-attacking antibodies, while those with more eudaimonic well-being experienced an increase in antibody production.
