Faith Healing & Prayer
Belief, Community, and the Limits of the Miraculous
Evidence grade 1 of 5, Untested. Read how the Atlas grades evidence.
The honest assessment cleanly separates the spiritual and psychological from the physical-cure claims. On wellbeing: religious and spiritual practice, including prayer, is associated in research with benefits for coping, mental health, stress, and quality of life during illness, real and valuable effects, largely via meaning, hope, and community. On directly curing physical disease: controlled studies of intercessory prayer (notably the large STEP study of prayer for cardiac surgery patients) have found no benefit on medical outcomes, and there is no scientific evidence that prayer or faith healing cures physical disease beyond what is explained by natural recovery, the meaning response, and coincidence. The honest framing: faith and prayer offer genuine, well-documented support for the emotional, social, and spiritual experience of illness, and are deeply meaningful to billions, but there is no good evidence they cure physical disease, and they should accompany, never replace, medical treatment. Respect for the practice and honesty about the evidence coexist.

What can go wrong
For most people, prayer and faith practice alongside medical care are entirely benign and often genuinely supportive, and that is how the vast majority engage with it. The serious, well-documented danger is a specific minority pattern: when faith healing replaces medical care, especially for a child. Asser and Swan documented 172 child deaths from religion-motivated medical neglect between 1975 and 1995, and estimated that 140 of those children would have had better than a 90 percent chance of survival with routine care (Pediatrics 1998). Within the Followers of Christ, parents in Oregon have been criminally convicted after children died of treatable conditions such as a blocked bladder or complications of premature birth, and a cemetery study in Idaho found child mortality far above the general population. Withholding effective treatment from a sick child or a vulnerable adult on faith-healing grounds can be fatal and is, in many jurisdictions, treated as neglect or homicide. Other risks include exploitation by fraudulent healers who take money and discourage care, and guilt when illness is framed as a failure of faith. Anyone facing a serious or acute illness, and anyone caring for a sick child, should seek and continue care from a qualified medical provider; faith is best kept alongside treatment, never in place of it.
Faith healing, the pursuit of health through prayer, ritual, and religious belief, appears in virtually every tradition on Earth and is among the most widespread health-related practices anywhere. It takes many forms, from intercessory prayer and laying on of hands to healing services and pilgrimage, and for most people it accompanies medical care rather than replacing it. Two things need to be kept apart honestly. Personal faith and religious community are associated with better coping, hope, and wellbeing during illness, though these findings are observational and confounded. The specific claim that praying for a sick stranger improves their medical outcome has been tested and did not hold up: the large STEP trial found no benefit and a complication signal in patients told they were being prayed for. The gravest, best-documented harm is substitution, the preventable deaths of children when families rely on prayer alone and refuse effective treatment.
Prayer and spiritual healing across all faiths, genuinely supportive for meaning, hope, and coping, but not shown to cure physical disease, and dangerous when it replaces care.
What people take it for
These are the reasons people give for taking it. They are not effects it has been shown to have.
How it is supposed to work
The well-supported mechanisms of faith and prayer in illness are psychological and social, not supernatural intervention in physiology: prayer and religious practice can reduce stress and anxiety, foster hope, meaning, and acceptance, mobilize powerful social and community support, and engage the meaning response, all of which genuinely affect wellbeing, coping, and quality of life, and indirectly health behaviors. Claims of direct supernatural cure of physical disease are, by nature, outside what science can mechanistically explain or demonstrate. So the real, measurable benefits operate through mind, behavior, and community; the miraculous claims remain a matter of faith.
What people get wrong
Often saidStudies prove that praying for the sick makes them recover.
ActuallyThe specific claim was tested in controlled trials and did not hold. The large STEP trial (Benson et al., Am Heart J 2006, n=1,802) found intercessory prayer had no effect on recovery from cardiac bypass, and the 2009 Cochrane review of 10 trials found the evidence supports no recommendation either way. Prayer is associated with better coping and wellbeing, but there is no good evidence it cures physical disease.
Often saidFaith healing and medicine are fundamentally opposed.
ActuallyThey are not in conflict when faith accompanies medical care, which is how the vast majority engage with it, and most religious traditions, including Islamic ruqyah, frame spiritual healing as a means alongside seeking treatment. The danger arises only when faith healing replaces effective care, especially for children.
Often saidA miraculous cure is common at healing shrines.
ActuallyEven at the most famous Catholic site, Lourdes, which draws roughly three million pilgrims a year, only about 70 cures have been recognized as officially miraculous since 1858, each after years of medical review by the Lourdes Medical Bureau. Officially confirmed cures are extremely rare relative to the number of pilgrims.
Often saidOnly fringe sects have lost children to faith healing.
ActuallyAsser and Swan documented 172 child deaths from religion-motivated medical neglect across 23 sects and multiple states (Pediatrics 1998), and 140 of those children would have had better than a 90 percent chance of survival with routine medical care.
Who profits, and who pushes back
Religion-and-health research
Associates religious and spiritual practice, including prayer, with better coping, mental health, and quality of life during illness, largely through meaning, hope, and community.
Intercessory-prayer trials
Found no benefit of intercessory prayer on medical outcomes in controlled studies, including the large prayer-for-cardiac-surgery trial.
Faith communities
Hold prayer and spiritual healing as profound sources of meaning, comfort, and hope in illness, woven into the religious life across traditions.
Child-protection & medicine
Document preventable deaths, especially of children, when faith healing replaces medical care, and stress that prayer should accompany, never replace, effective treatment.
Where the research comes from
Most of the published research on this comes from one place. 85% of it is from Global (all major faiths). Findings that no unrelated group has reproduced are weaker than the study count makes them look.

How we got here
Healing through appeal to the divine is as old as recorded religion. In ancient Greece the sick slept in the sanctuaries of Asclepius, at Epidaurus and roughly 200 affiliated healing sites, practicing enkoimesis, or dream incubation, awaiting a cure from the god; inscribed stelae there recorded named patients and their reported cures. Comparable temple medicine, sacred springs, and priest-healers appear across Egypt, Mesopotamia, and beyond. In the Islamic world, ruqyah, healing through Quranic recitation and supplication, traces to the Prophet Muhammad and his companions and continues today, traditionally understood as a means alongside medicine, not a replacement. Christian traditions carried healing through medieval shrines and relics into modern Pentecostal, charismatic, and televangelist movements, while pilgrimage sites such as Lourdes, drawing roughly three million visitors a year since 1858, have recognized only around 70 cures as officially miraculous after long medical review. Controlled research later clarified that measurable benefits are psychological and social rather than a cure of disease.

How it is understood
Faith healing, the use of prayer, religious ritual, and spiritual belief to seek healing, is found in virtually every religious tradition and is among the most widespread health-related practices on Earth. It takes many forms: intercessory prayer (praying for the sick, by them or on their behalf), the laying on of hands and anointing, healing services and charismatic ministries, pilgrimages to sacred sites and shrines (Lourdes, sacred springs, holy relics), and countless personal and communal devotions. Across faiths, illness and healing are woven into the religious life, sought through and understood within a relationship with the divine. For believers, prayer and spiritual practice during illness are sources of profound meaning, comfort, hope, and community, and most people who pray about illness do so alongside, not instead of, medical care. This entry treats faith healing respectfully as a near-universal spiritual practice, while being honest about what controlled research has and has not found regarding its effects on physical disease.
