The health benefits of religion: Are non-religious parents short-changing their kids?

For decades, we’ve heard about studies confirming links between good health, life satisfaction, and participation in religion.

And some claims seem uncontroversial.

Who would argue against the idea that certain religious practices--like prohibitions against smoking--protect health (Whooley et al 2002)?

Or that many people derive a sense of comfort from their religious beliefs? That religion can offer some people a way cope with stress?

What’s more contentious is the idea that religion is intrinsically or uniquely beneficial for a person’s health and sense of well-being.

The idea that faith causes people to enjoy better health.

That prayer heals.

That ritualized worship makes people happier or more satisfied with life.

These claims have been used to argue that families should be encouraged to practice religion. Some people have even suggested that doctors should prescribe religious activities to their patients.

But does the scientific evidence favor these claims?

Not really.

Because most studies linking religion with good health--or life satisfaction--are correlational only. They don’t tell us that religious practice causes health or happiness.

We might suppose the causation works the other way. Maybe healthier people have an easier time participating in religious activities. Maybe happier people are more motivated to maintain religious ties. As Richard Sloan and his colleagues have argued (1999), many studies have failed to rule out these alternatives.

But let’s assume that something about religion causes improved health and life satisfaction. Does it follow that it’s the doctrine or ritual that makes people feel better?

No. In fact, two recent studies suggest the contrary. The psychological perks and health benefits of religion may stem from the social support offered by religious communities.

For example, researchers Chaeyoon Lim and Robert Putnam (2010) re-analyzed data collected on the religious activities of American adults.

The researchers found a connection between attending religious services and a self-reported sense of well-being. But the effect seemed to depend on friendship.

People who expressed greater certainty about their religious beliefs did not express greater personal satisfaction. Nor did people who prayed or conducted religious services at home.

What seemed really important was a combination of factors--expressing a strong religious identity, meeting frequently with a religious congregation, AND having close friends in that congregation. People who met all three criteria were more likely to say they were “extremely satisfied” with their lives.

Religious attendees who lacked close friends in the congregation were no more likely to be “extremely satisfied” than were people who said they didn’t attend services at all.

As Lim notes in a public statement, “To me, the evidence substantiates that it is not really going to church and listening to sermons or praying that makes people happier, but making church-based friends and building intimate social networks there.”

And what about health?

Amanda Nicholson and her colleagues (2010) published a study that analyzed the relationship between religious participation and self-reported health among Europeans.

The researchers reviewed data on people from 23 different countries. They found that frequent attendance of religious services was linked with better self-ratings of health. But that was not true of prayer. The more frequently a person prayed, the less likely he was to report good health.

This might reflect the possibility that healthy people are less motivated to pray. But the results are also consistent with the idea that it’s the social aspects of religion that improve quality of life.

Does this mean that religious people shouldn't claim that their faith makes them feel healthier or happier? Of course not.

But for now it’s not clear that participating in religion makes people any healthier or happier than participating in secular activities--not if those secular activities feature frequent meetings, friendship, and a strong sense of social identity.
