Regular churchgoers seem to do better than non-churchgoers or occasional churchgoers in terms of their daily positive wellbeing experiences. This is the finding of a recent analysis of data from more than 300,000 interviews collected as part of the Gallup-Healthways Well-Being Index in 2011.
Not only do Americans who attend a church, synagogue, or mosque frequently report having higher wellbeing in general, but they also get an extra boost to their emotional state on Sundays -- while the rest of Americans see a decline in their mood.
In short, most Americans, religious and secular, feel happier on the weekend than during the week as there is greater chance for leisure and/or opportunity to spend time with one's family and friends. Read more of the details of this study at this site.
