Sweat Lodge Ceremony

Ceremonies of many Nations

The sources reviewed describe sweat lodge ceremonies as belonging to particular Indigenous Nations, not to one shared tradition. A Manitoba government heritage text draws on interpretations given by a Midewewin society, the Roseau River Three Fires Society, in a 1989 to 1990 study. It presents the sweat lodge as very important within the Anishinabe (Ojibway, Saulteaux) Midewewin and says the lodge was given to the Anishinabe as a means of purifying the mind and body. The text adds that these interpretations are not the only authentic version.

None of the sources reviewed establishes when or where the ceremony first arose, and this page does not offer a date. Origin accounts are held by the communities concerned, and several are told as teachings that are not summarized here.

Colonization, suppression and renewal

An Anishinaabe scholar at Western University writes that her paper on the women's sweat lodge (madoodiswan) advocates the reclamation and resurgence of Anishinaabeg women's traditional ecological knowledge after hundreds of years of colonization. A research team that includes members of an Anishinaabe First Nation states that Indigenous Peoples have always valued traditional healing practices, while little research on their efficacy exists.

The Mesoamerican temazcal as a parallel

A 2001 historical and anthropological essay reports that the temazcal, a steam bath, is found today among 24 ethnic groups in 14 Mexican states. Sixteenth-century friars and officials recorded it in their reports, and the author says colonial authorities tried to restrict its use. The author argues that later writers narrowed the temazcal to a medicinal function and says it should not be confused with similar structures elsewhere in the Americas or the world.

Names used by different peoples

Sweat lodge is an English label applied to many separate ceremonies. The Anishinaabe scholar cited here uses the Anishinaabemowin word madoodiswan for the sweat lodge. The Mexican essay gives the Mesoamerican steam bath as temazcal, a spelling it chooses to stay close to the Nahuatl sound, and lists other local names, including chuj in Mame and pus in Tzeltal. Other Nations have their own names, and the sources reviewed document only some of them.

Ceremony, intervention and imitation

Researchers often class the sweat lodge as a traditional ceremonial practice or a cultural intervention. A systematic review notes that such practices are defined by each community, so findings may not carry across tribal settings. Indigenous commentators separately use the word lodge when criticizing paid events run by outsiders, which one Navajo columnist calls a distorted imitation of a real ceremony.

A sweat lodge ceremony differs in purpose and setting from a sauna session. Heat exposure in a sauna is covered on the Infrared Sauna page and is a physical-agent practice with its own research.

Neighboring pages

Ceremonies of the Native American Church are a separate subject, covered on the Peyote and the Native American Church page. The Plant Medicine and Spiritual Cleansing pages cover other practices that sometimes use similar language. Core shamanism and neo-shamanism is a distinct modern movement, and the Lakota statement discussed below criticizes self-styled shamans who offer sweat lodge programs.

General features reported

The Manitoba heritage text describes the lodge as primarily a purification rite and a first step toward other ceremonies. It says physical, emotional and spiritual purification is a necessary preparation for many religious ceremonies, especially for people undertaking sacred instruction, and that the ceremony must be conducted in accordance with a proper understanding.

A scoping review of addiction programs states that cultural interventions are led by individuals who are sanctioned and recognized by traditional teachers, along with community members. It describes Elders and traditional healers as central to many programs.

What this page leaves out

This page does not describe ritual sequences, songs, prayers, objects or teachings. Communities treat these as sacred or restricted, and they differ between Nations and between lodges. The Lakota statement discussed below holds that such ceremonies are for traditional spiritual leaders of the Lakota, Dakota and Nakota peoples, and a Manitoba text notes that interpretations of sacred sites are not meant to be a single version.

Use inside treatment programs

In a scoping review of 19 studies of cultural interventions for addictions among Indigenous populations in the United States and Canada, sweat lodge ceremonies were the most commonly reported cultural intervention, appearing in 68 percent of studies. All of the programs combined Western and culture-based treatment. A qualitative study in Ontario reports a program that combined the sweat lodge with Seeking Safety, a Western treatment model for trauma and substance use.

Purposes described by communities and scholars

The Manitoba text, reflecting Midewewin interpretations, describes purification of the mind and body and preparation for further ceremony. It also says the lodge by itself can relieve some sicknesses in the text's own wording, a claim attributed to those interpretations that this page does not evaluate. The Anishinaabe scholar describes the women's lodge as a setting for teaching, ecological knowledge and personal vision, from her own standpoint and not as a general rule for all lodges.

Uses in trauma and addiction care

Many traditional healers and Elders, according to the authors of a 2018 study, agree that strengthening cultural identity, using traditional healing practices and encouraging community integration can improve mental health and reduce substance use disorders in Indigenous populations. Programs that include the ceremony state aims such as reducing intergenerational trauma symptoms and substance use. These are stated aims and beliefs, and the evidence for them is covered in the next section.

Systematic review of ceremonial practices and substance use

A 2023 systematic review examined traditional ceremonial practices as a strategy to reduce problem substance use in American Indian communities. It included 10 studies: one randomized controlled trial, one pilot study, one prospective cohort study, four evaluation studies and three cross-sectional studies, seven urban and three reservation based. Sweat lodge was among the practices in several of them. Risk of bias was rated serious in several studies and none was rated low, and the inconsistent measures ruled out meta-analysis.

The reviewers describe the literature as showing promise for approaches that are effective and culturally congruent, and as emerging and warranting further research. They note that practices differ by community, so findings may not generalize across tribal settings.

Scoping review of cultural interventions

A 2014 scoping study searched 12 scientific and 13 grey literature databases up to October 2012 and included 19 studies involving 5,949 clients. Reducing or eliminating substance use was reported in 74 percent of studies. No study used a true experimental design, most samples had fewer than 100 participants, and follow-up was usually short. Only two studies compared Indigenous and Western components directly: one found the culturally based intervention more effective, and the other found no difference.

Because participation in ceremonies was usually voluntary and often unreported, the reviewers could not tell whether outcomes reflected the intervention or how it was delivered. They conclude that culture-based interventions appear beneficial for wellness and call for better designed studies.

Qualitative findings

A 2018 qualitative article by authors from the Northern Ontario School of Medicine and an Anishinaabe First Nation reports that participants described gains in spiritual and emotional well-being that they attributed directly to the sweat lodge ceremony. The abstract notes earlier work by one author in which blending Indigenous healing with Seeking Safety was followed by reduced intergenerational trauma symptoms and substance use. The abstract gives no sample size or controls, so it reports participants' perceptions and does not test cause.

What the evidence does not cover

The studies above evaluate programs in which the ceremony is one element among several, so none isolates the ceremony or its heat. Searches run for this page, combining sweat lodge with systematic review, randomized trial, hyperthermia and Indigenous mental health, found no randomized trial of the ceremony alone. Studies of sauna or heat physiology are not studies of the ceremony and are not used here.

Lakota statement against exploitation

A published statement, titled a declaration of war against exploiters of Lakota spirituality, criticizes companies that charge admission to sweat lodge and vision quest programs and non-Indian leaders and New Age practitioners who offer imitations of Lakota ceremonies. A history education site attributes it to three Lakota spiritual leaders. It states that such ceremonies are for the Lakota, Dakota and Nakota peoples and urges resistance, and it also condemns Native individuals who authorize outsiders to use ceremonies for profit.

The statement was passed unanimously on June 10, 1993, at Lakota Summit V, according to the People’s Paths page that reproduces it, which says about 500 representatives of 40 tribes and bands attended. A 2009 Indian Country Today column also dates adoption to 1993, while the Digital History reproduction is dated 1998.

Objections to commercial lodges

The column quotes a Cree, Anishnawbe and Assiniboine healer who argues that charging a price destroys a ceremony's sacredness and that observers may wrongly believe they can perform ceremonies without proper teaching. It also quotes a Lakota traditional spiritual leader who calls for an end to the abuse of these traditions. These are the positions of the people quoted, and other Indigenous people may hold different views.

Heat illness and general risk factors

The US Centers for Disease Control and Prevention (CDC) lists adults 65 and older, infants and young children, people with chronic medical conditions and people who are pregnant among those at increased risk of heat-related illness. This guidance concerns hot weather, not the ceremony, and cannot be read as an assessment of any lodge.

CDC guidance for clinicians, which reflects expert opinion, says some medicines can impair heat tolerance, including diuretics, antipsychotics, anticholinergics and stimulants, and that alcohol increases urination and impairs perception of heat. People on regular medicines or with medical conditions are the audience for individual advice from their own clinician.

Documented deaths and what sources conclude

A 2005 forensic case report describes a 37-year-old man who died of dehydration and heat exposure after a sweat lodge ceremony in outback Australia. The authors, who coin the term sweat lodge syndrome, list prolonged heat in an uncontrolled setting, inadequate hydration, failure to recognize loss of consciousness, ineffective alternative treatments and delayed medical care. They conclude that adopting rituals from other cultures may not be entirely safe, and they advise that people with significant cardiovascular disease, people on medicines that predispose to hyperthermia, and people who have drunk large amounts of alcohol should not enter sweat lodges.

A 2009 column describes a paid retreat session near Sedona, Arizona, for which participants paid $9,695, after which two people had died and others were hospitalized at the time of writing. The columnist, a Navajo journalist, calls the event a distorted imitation and not a real ceremony. This page draws only on that column and names no individuals in connection with the event.

Setting, leadership and care boundaries

Scholarly sources on addiction programs describe ceremonies led by people recognized by traditional teachers, and Indigenous commentators describe paid lodges run by outsiders as imitations. These sources do not provide a safety comparison between the two settings. The forensic authors recommend that participants understand the medical risks before entering any lodge. Ceremony does not replace medical assessment, and people with symptoms of heat illness or loss of consciousness need prompt medical care.
