German‑Austrian Monastic Study Shows Monks and Nuns Outlive Peers

A 30‑year research project called the German‑Austrian Cloister Study examined roughly 16,600 members of male and female religious orders in Germany and Austria, with some participants in Switzerland and Italy. Led by demographer Marc Luy of the Vienna Institute of Demography (Austrian Academy of Sciences), the study compared health, lifestyle and mortality among monks, nuns and the general population.

The findings indicate that the usual gap in life expectancy between men and women almost disappears inside monastic communities. Regular routines, scheduled prayer, communal living and a clear purpose appear to foster “successful aging.” Biological factors account for only about one year of the gender gap in overall life expectancy, while non‑biological causes—particularly risky male behaviours—drive larger differences in the broader population. The research has drawn renewed attention following the centennial celebration of Benedictine Brother David Steindl‑Rast.

The study suggests that lifestyle and social environment, rather than genetics alone, play a decisive role in longevity, offering insights for public‑health strategies aimed at extending healthy life years.
