Across medicine and society, there's increasing interest in the link between religion/spirituality and health. Three-quarters of all U.S. medical schools now offer courses in spirituality and medicine. Yet many researchers are skeptical about the union of religion/spirituality and medicine. Findings, published in 2006 in the American Heart Journal, showed that being prayed for did not improve outcomes, and it seemed to have a negative effect when patients knew they were the subject of prayers from afar.
