Faith, Prayer, and Healing
In cultures all around the world, spirituality has historically played a large and important role in healing. In today’s science-based, technological world, these practices sometimes fall into the category of complementary and alternative medicine (CAM). But how large a role does prayer still play in today’s world?
Looking at the Evidence
Most studies cannot determine if faith really helps because there is no clear medical reason for changes in the course of disease. In a world of medicine based on scientific evidence, this is something that cannot be measured. At best, evidence is mixed and controversial.
Here are a few of the studies that assess the power of prayer.
A study conducted in California on the effects of prayer found that patients with advanced
who were prayed for survived in greater numbers, got sick less often, and recovered faster than those who did not receive prayer. Researchers have also studied the role of distant healing, which includes prayer and spiritual healing, in people with AIDS. One study involving 156 patients did not find any benefit. Another small study found some benefit with patients' overall mood who received distant prayer, but found no clinical difference in the outcomes of any patients. The participants in these studies were aware if they were or were not being prayed for.
Another study focused on women undergoing in vitro fertilization
. The group that was prayed for had improved pregnancy rates compared to the women who were not prayed for. The participants in this study were not informed that they were the recipients of prayer.
One study looked at the effects of prayer on patients admitted to a cardiac care unit . This study found that patients receiving prayer had fewer side effects from these procedures than people not prayed for.
In contrast, 2 other large studies, found that being prayed for did not affect the number of complications people had after undergoing coronary artery bypass grafting
or coronary balloon angioplasty. In one study, the patients who knew that they were being prayed for actually had more complications. However, there were patients who refused treatment which may have affected the rate of complications. The participants in these studies were aware if they were or were not being prayed for.
Many studies have failed to prove the effects of prayer. One such trial from researchers at the Mayo Clinic followed 799 patients for 6 months after discharge from the hospital coronary care unit. This trial found no significant effect of prayer on the medical outcomes. The participants in these studies were aware if they were or were not being prayed for.
Some studies were also conducted on psychiatric patients. In Australia, a triple-blind study using intercessory prayer was conducted on children with psychiatric conditions, meaning the study participants, family members, and doctors were not aware that others were praying for them. There was no additional benefit found in the children who had people pray for them compared to those who had normal treatment.
Spirituality is very individual and it is difficult to prove if intercessory prayer affects patients. If it makes you feel better, or makes you feel like you are making progress against your condition, then there is no harm in continuing what you practice.
Addressing Spiritual Concerns
In the end, what seems most important is your view about the effect of faith and prayer on your own healing process. If you are facing a challenging diagnosis or an upcoming surgery, you may want to share your spiritual concerns with your doctor. This information may help your doctor gain an understanding of how you are coping with these changes in your health.
