Want to live longer? Consider joining a church.
People who are religious live an average of four years longer than those who have no ties to religion, a study published Wednesday in the journal Social Psychological and Personality Science. The researchers analyzed the obituaries of more than 1,000 people around the country, and adjusted for other factors that can affect lifespan, including the gender and marital status of the deceased.
“Religious affiliation had nearly as strong an effect on longevity as gender does, which is a matter of years of life,” said Laura Wallace, lead author of the study and a doctoral student in psychology at The Ohio State University.
This isn’t the first study that has tied religious belief to living longer. People who go to church at least once a week[1] are at a 33% lower risk for death, a 2016 study of more than 75,000 people found.
Researchers believe the health benefits of religion have to do with its ties to volunteering and being part of a community. Strong social ties can boost survival rates[2] by 50%, a survey of more than 100 years of research released in 2010 found.

But that isn’t the only reason for the boost in longevity, according to Wallace. “We found that volunteerism and involvement in social organizations only accounted for a little less than one year of the longevity boost that religious affiliation provided,” she said. “There’s still a lot of the benefit of religious affiliation that this can’t explain.”
Those benefits could come from meditation and other stress-reducing practices, including prayer, the researchers said. Some preliminary studies have shown that meditation leads to fewer deaths from heart disease and cancer, though their sample sizes were relatively small[4].

Peer pressure to live a healthier life may also help. Other factors related to religion that could boost longevity include abstaining from unhealthy habits like drinking and drugs, according to the researchers. Not drinking or smoking are two of five healthy habits pinpointed by a study released in June that can make people live 10 years longer.
The other three healthy habits are eating a healthy diet, exercising 30 minutes a day, and maintaining a body mass index between 18.5 and 24.9. Men and women who make these lifestyle changes are 82% less likely to die[6] from cardiovascular disease and 65% less likely to die from cancer, the study found.
