The effect of prayer on physical health: Experimental evidence

Abstract

There has been enough published scientific work on the direct effects of prayer upon physical health in the past thirty years to merit review. While experimental evidence has yet to reveal large direct effects of prayer on physical health, the effects which have been found are notable and encourage further study. In this article the authors review the major studies, discuss problems in their interpretation, and suggest considerations for future experimental study of prayer. © 1994 Institutes of Religion and Health.
