Spontaneous Human Combustion

Record	OBS-0451
Category	Unexplained/Natural Phenomena
Status	DEBUNKED
Summary	Spontaneous human combustion (SHC) is the pseudoscientific belief that a living human body can catch fire without an external ignition source. Proponents claim that victims burn intensely, often leaving only ashes and limbs, while nearby objects remain undamaged. The scientific consensus is that these cases involve overlooked external sources of ignition, such as the wick effect.
Origin	The term and concept were first proposed in 1746 by Paul Rolli in an article about the death of Countess Cornelia Zangari Bandi, published in Philosophical Transactions.
Claimed	The body can ignite spontaneously without an external source of ignition. Victims are often chronic alcoholics, typically elderly females. The fire leaves a greasy, fetid ash residue and causes little damage to surrounding combustibles. Hands and feet often fall off, and the body burns intensely while nearby objects remain intact. There have been about 200 reported cases worldwide over 300 years.
Evidence / consensus	Scientific investigations attribute reported cases to external ignition sources, such as the wick effect, where clothing or hair acts as a wick and body fat as fuel. Alcoholism and proximity to open flames are common factors. No credible case has been proven to occur without an external ignition source.

> OBSERVER NOTE:
Catalogued as a classic pseudoscientific claim. The evidence consistently points to mundane fire dynamics, not supernatural ignition. The persistence of SHC in popular culture is a testament to the allure of the unexplained.
