Israeli Jewish adults who attend synagogue and consider themselves religious are significantly healthier and happier than their non-religious counterparts.

One study, published in Psychology of Religion and Spirituality, an official journal of the American Psychological Association, used 2010 data on 1,849 Jewish adults from the Israeli sample of the European Social Survey. The other study, published in the Journal of Happiness Studies, used 2009-10 data on 991 Jewish adults from the Israeli sample of the International Social Survey Programme's Religion III survey.
These new results confirm findings from other studies of Jews in Israel and the U.S. conducted over the past few years. Seven such studies have been published by Levin using data from a variety of national and global surveys. They have consistently identified facets of Jewish religious expression as among the most reliable predictors of measures of physical and mental health and overall well-being.
