Firewalking is the act of walking barefoot over a bed of hot embers or stones. It has been practiced by many people and cultures in many parts of the world, with the earliest known reference dating from Iron Age India . It is often used as a rite of passage, as a test of strength and courage, and in religion as a test of faith.
Modern physics has explained the phenomenon, concluding that the foot does not touch the hot surface long enough to burn and that embers are poor conductors of heat.
Historical and cultural forms Walking on fire has existed for several thousand years, with records dating back to 1200 BCE. (livescience.com) Cultures across the globe use firewalking for rites of healing, initiation, and faith.
Firewalking is not a single tradition transmitted from one point of origin. Walking on embers or heated stones, fire-handling, and healing dances involving fire have been documented in several independent religious and cultural settings. Their meanings include vows, tests of faith, healing and protective rites, communal festivals, and rites of passage. Related practices should not automatically be treated as variants of one universal ritual.
The Anastenaria of northern Greece and the Bulgarian nestinarstvo are icon-bearing rites associated with the feast of Saints Constantine and Helen. Historical and ethnographic accounts of the tradition have also been shaped by Greek and Bulgarian national historiographies. UNESCO inscribed the nestinarstvo rite on the Representative List of the Intangible Cultural Heritage of Humanity in 2009.
At San Pedro Manrique in Spain, participants cross an oak ember bed during the annual midsummer festival, with some walkers carrying a relative or friend on their back. The ceremony has become the setting for twenty-first-century anthropological and physiological field studies. Firewalking or ceremonies on heated stones have also been described in Fiji, parts of Polynesia, India, Sri Lanka, Japan, and other regions.
Among the !Kung, fire and heat form part of communal healing dances associated with the activation of n/um and the altered state called !kia. Richard Katz reported that healers might dance close to or enter the fire and handle coals. The practice is embedded in a wider system of community healing and should not be reduced to recreational or motivational firewalking.
In the twentieth-century United States, some Holiness congregations practiced ritual fire-handling, including applying flames to the hands, feet, or face. Steven M. Kane's sixteen-month ethnographic study in six southern states interpreted the practice in relation to belief in protection by the Holy Spirit, religious arousal, and culturally mediated responses to pain. This is fire-handling rather than ember-bed walking, although comparative studies of fire rituals sometimes discuss the two together.
Firewalking is also practiced by: The Sawau clan on the island of Beqa, to the south of Viti Levu in the Fijian Islands. The phenomenon was examined in 1902 when it was already a tourist attraction, with a "Probable Explanation of the Mystery" arrived at.

Modern Western practice
From the 1980s, firewalking became increasingly visible in the United States and Western Europe as a secular motivational and personal-development exercise. Contemporary scientific and popular accounts examined both its ordinary physical explanation and the psychological meanings that organizers and participants attached to a successful crossing.
The Global Firewalking Alliance's history page republishes Peggy Dylan's first-person essay “Red, Hot, and Healing.” Dylan does not claim to have originated firewalking; she describes her role as helping bring it to public attention in Western consciousness and personal-development settings. This is a participant account and primary source, not an independent history of the movement.
Persistence and functions
Social theorists have long argued that the performance of intensely arousing collective events such as firewalking persists because it serves some basic socialising function, such as social cohesion, team building, and so on. Émile Durkheim attributed this effect to the theorized notion of collective effervescence, whereby collective arousal results in a feeling of togetherness and assimilation.Durkheim E. ‘’The elementary forms of religious life’’. New York: Free Press 1995. A scientific study conducted during a fire-walking ritual at the village of San Pedro Manrique, Spain, showed synchronized heart rate rhythms between performers of the firewalk and non-performing spectators. Notably, levels of synchronicity also depended on social proximity. This research suggests that there is a physiological foundation for collective religious rituals, through the alignment of emotional states, which strengthens group dynamics and forges a common identity amongst participants.Konvalinka, I., Xygalatas, D., Bulbulia, J., Schjoedt, U., Jegindø, E-M., Wallot, S., Van Orden, G. & Roepstorff, A. 2011. “Synchronized arousal between performers and related spectators in a fire-walking ritual”, ‘’Proceedings of the National Academy of Sciences 108’’(20): 8514-8519Xygalatas, D., Konvalinka, I., Roepstorff, A., & Bulbulia, J. 2011 "Quantifying collective effervescence: Heart-rate dynamics at a fire-walking ritual",Communicative & Integrative Biology 4(6): 735-738
Social and psychological research
Firewalking is studied as a high-arousal collective ritual as well as a heat-transfer phenomenon. Its meanings and effects depend on cultural setting, religious framing, social relationships, expectations, and the organization of the event.
Anthropological writing has consequently treated firewalking not only as a physical puzzle but also as a question about how bodily experience is interpreted within a social and cultural setting. A broader review of ritual psychology organizes proposed effects of ritual around emotion regulation, performance-related goals, and social connection. The review concerns ritual generally and does not demonstrate that firewalking has clinical or lasting coaching effects.
A field study at the annual firewalking ritual in San Pedro Manrique, Spain, recorded heart-rate dynamics from 38 people. During the ritual, the heart-rate patterns of firewalkers became synchronized with those of spectators who were their relatives or friends, but not with unrelated spectators.
A pre–post field study of a Mauritian Hindu firewalking ceremony found that firewalkers showed the greatest increase in heart rate and reported greater happiness after the ritual than related non-walkers and unrelated spectators. The study was quasi-experimental and does not establish that firewalking produces lasting personality change, “rewires” the brain, or causes a specific neurochemical response. A review of the physics and psychology of firewalking concluded that trance-like or excited states may affect the participant's subjective experience but are not required for a successful crossing. The cited field studies did not isolate the possible effects of facilitator behaviour, participant expectations, group conformity, or peer pressure in modern coaching-style firewalks; they therefore do not demonstrate those proposed mechanisms.
Physics
Per the second law of thermodynamics, when two bodies of different temperatures meet, the hotter body will cool off, and the cooler body will heat up, until they are separated or until they meet at a temperature in between. What that temperature is, and how quickly it is reached, depends on the thermodynamic properties of the two bodies. The important properties are temperature, density, specific heat capacity, and thermal conductivity.
The square root of the product of thermal conductivity, density, and specific heat capacity is called thermal effusivity, and determines how much heat energy the body absorbs or releases in a certain amount of time per unit area when its surface is at a certain temperature. Since the heat taken in by the cooler body must be the same as the heat given by the hotter one, the surface temperature must lie closer to the temperature of the body with the greater thermal effusivity. The bodies in question here are human feet (which mainly consist of water) and burning coals.
Due to these properties, David Willey, professor of physics at the University of Pittsburgh at Johnstown, points out that firewalking is explainable in terms of basic physics and is neither supernatural nor paranormal. Willey notes that most fire-walks occur on coals that measure about , but he once recorded someone walking on coals.
Additionally, Jearl Walker has postulated that walking over hot coals with wet feet may insulate the feet due to the Leidenfrost effect.
Factors that prevent burning Water has a very high specific heat capacity (4.184 J g−1 K−1), whereas embers have a very low one. Therefore, the foot's temperature tends to change less than the coal's. Water also has a high thermal conductivity, and on top of that, the rich blood flow in the foot will carry away the heat and spread it. On the other hand, embers have a poor thermal conductivity, so the hotter body consists only of the parts of the embers which are close to the foot. When the embers cool down, their temperature sinks below the flash point, so they stop burning, and no new heat is generated. Firewalkers do not spend very much time on the embers, and they keep moving.
Risks when firewalking People have burned their feet when they remained in the fire for too long, enabling the thermal conductivity of the embers to catch up. One is more likely to be burned when running through the embers since running pushes one's feet deeper into the embers, resulting in the top of the feet being burnt. Foreign objects in the embers may result in burns. Metal is especially dangerous since it has a high thermal conductivity. Embers which have not burned long enough can burn feet more quickly. Embers contain water, which increases their heat capacity as well as their thermal conductivity. The water must be evaporated already when the firewalk starts. Wet feet can cause embers to cling to them, increasing the exposure time. A myth that persists is that safe firewalking requires the aid of a supernatural force, strong faith, or an individual's ability to focus on "mind over matter".
Contemporary organized practice
Since the late twentieth century, firewalking has also been used outside traditional religious settings in motivational seminars, personal-development programs, corporate events, professional instruction, and charity fundraising.Since the 20th century, this practice is often used in corporate and team-building seminars and self-help workshops as a confidence-building exercise. These applications vary widely in purpose and method and should be distinguished from historically continuous religious practices. Claims of therapeutic or lasting psychological benefit are not established clinical effects.
