Firewalking is the act of walking barefoot over a bed of hot embers or stones.

Firewalking has been practiced by many people and cultures in all parts of the world, with the earliest known reference dating back to Iron Age India – c. 1200 BC. It is often used as a rite of passage, as a test of an individual's strength and courage, or in religion as a test of one's faith. Firewalking became popular in the twentieth century when author Tolly Burkan began giving public classes throughout the United States and Europe in an effort to demonstrate that the practice was not paranormal.

Today, it is often used in corporate and team-building seminars and self-help workshops as a confidence-building exercise. Firewalking is frequently held to imply that the feat requires the aid of a supernatural force, strong faith, or on an individual's ability to focus on "mind over matter". Modern physics has attempted to explain the phenomenon by claiming that the amount of time the foot is in contact with the ground is not enough to induce a burn, combined with the fact that coal is not a very good conductor of heat.. These explanations have however been refuted: Emergency room physicians assert that shorter contact with less hot coal than is common in firewalking is sufficient to completely char skin. Furthermore, firewalkers have walked on red hot metal, which is an excellent conducter of heat. A currently unrefuted physical explanation is that under relaxed mental conditions, blood flowing through the feet can transport away the heat of the coal quickly enough to prevent burning. In this case, belief in a higher power or confidence in a theory is the factor inducing the necessary relaxation for the cooling process to function properly.
