firewalking

Walking on fire has existed for several thousand years, with records dating back to 1200 BCE.{{cite news | url=http://www.livescience.com/othernews/060814_mm_firewalker.html | title=World's Watch and Learn: Physics Professor Walks on Fire | publisher=Livescience.com |date=2006-08-14 | first=Corey | last=Binns | access-date =2007-04-13}} (livescience.com){{Unreliable source?|date=March 2010}} Cultures across the globe use firewalking for rites of healing, initiation, and faith.

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.{{cite book|last1=Vilenskaya|last2=Steffy|first1=Larissa|first2=Joan|title=Firewalking: A New Look at an Old Enigma|date=December 1991|publisher=Bramble Co|isbn=978-0962618437|pages=[https://archive.org/details/firewalkingnewlo00vile/page/n253 253]|edition=First|url-access=registration|url=https://archive.org/details/firewalkingnewlo00vile/page/n253}}{{cite book|last1=Leonardi|first1=Lewis|title=The Ultimate Experience of Fire & Ice|date=1998|publisher=Davinci Press|location=Google Books|isbn=978-0966467703|edition=1st}} 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.

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.{{cite news | url=http://www.straightdope.com/classics/a3_036.html | title=Can you walk on hot coals in bare feet and not get burned? | publisher=The Straight Dope |date=14 June 1991 | access-date =2007-04-13}} 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.{{cite news | url=http://www.pitt.edu/~dwilley/Fire/FireTxt/fire.html | title=Firewalking Myth vs Physics | publisher=University of Pittsburgh |year=2007 | first=David | last=Willey | access-date =2007-04-13}} Willey notes that most fire-walks occur on coals that measure about {{convert|1000|F|C}}, but he once recorded someone walking on {{convert|1800|F|C}} coals.

Additionally, Jearl Walker has postulated that walking over hot coals with wet feet may insulate the feet due to the Leidenfrost effect.{{cite web| first = Jearl | last = Walker| title=Boiling and the Leidenfrost Effect | url=http://www.wiley.com/college/phy/halliday320005/pdf/leidenfrost_essay.pdf| publisher=Cleveland State University|access-date=2015-05-19}}

• 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.

• 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".{{cite book|last=DeMello|first=Margo|title=Feet and Footwear: A Cultural Encyclopedia|year=2009|publisher=Macmillan|isbn=978-0-313-35714-5|pages=30–32|url=https://books.google.com/books?id=5QdKSxajwP0C&q=barefoot%20middle%20ages&pg=PA30}}

Since the 20th century, this practice is often used in corporate and team-building seminars and self-help workshops as a confidence-building exercise.{{cite web|last1=Edwards|first1=Emily D.|title=Firewalking: a contemporary ritual and transformation|url=http://libres.uncg.edu/ir/uncg/f/E_Edwards_Firewalking_1998.pdf|website=MIT Press|access-date=2015-10-17}}{{cite book|last1=Reynolds|first1=Ron|last2=Reynolds|first2=Denny|title=The New Perspective: Ten Tools for Self-Transformation|date=2005|publisher=Trafford Publishing|location=Google Books|isbn=978-1412047852|url=https://books.google.com/books?id=MxEi3yaCae4C}}
