Prayer and meditation as medical therapies.

Prayer and meditation have been used as health-enhancing techniques for centuries. Their use has been investigated more recently in the context of more conventional, allopathic medical approaches. These studies, despite methodological limitations, show some promise for the formal application and integration of these techniques into western medical practice. Some potential benefits from meditation include reduced perceived stress and improvement in mild hypertension. Prayer appears to offer subjective benefit to those who pray; the effects of intercessory prayer on the health status of unknowing individuals requires more investigation.
