What effect does prayer have on our health? Dr. Larry Dossey discusses scientific research findings on prayer’s health benefits. He notes that numerous studies have found that people who pray tend to be healthier. Prayer causes heart rates to fall, it allows the body to relax, and it leads to longer lives. Studies have even found that people who pray for themselves going into surgery have a higher success rate. In addition, patients who have others praying for them, even without them knowing it, also will have a higher success rate in surgery. Dossey's definition of prayer is broad, encompassing all religions and cultures, and he adds that studies have found no religious preference in prayer's efficacy on health. Dossey explains his belief that faith and reason intersect and support one another.
