From The Boston Globe:
RELIGION CAN BE good for more than the soul, a growing number of studies seem to say. Over the past decade, academic research on religiosity has exploded, and with it has come a raft of publications suggesting that spiritual beliefs and practices can add years to life, lower blood pressure, or keep at-risk kids on the straight and narrow. As sociologists, psychologists, and physicians turn their attention to measuring the effects of religion, often fueled by grant money from private foundations, the results have percolated swiftly through weekend sermons and the popular media. Being nonreligious, one might conclude, looks more and more like a danger to your health.
But as the academic interest in religion has mounted, some scholars have begun to call this picture into question. What's missing, they believe, is a comparable examination into the lives of nonreligious people and even the potential benefits of nonbelief. Galvanized by a desire to even the scales, these researchers have been organizing academic centers to study the irreligious, conducting major surveys, and comparing their findings. They've already found that convinced atheists appear just as well equipped to cope with hardship as convinced believers, and that some of the world's healthiest societies have the lowest levels of piety.
