If you ’re familiar with the work of Charles Dickens , in particular his 1853 novelBleak House , you may also be cognisant of a foreign phenomenon termed “ self-generated human burning ” . In arguably the most renowned literary case of this curiosity , Dickens details the grisly death of junk merchandiser Mr Krook , who get together a fervent end , go away behind just a peck of ash and a “ colored greasy coat on the walls and ceiling ” .
However , the concept is n’t solely consigned to Dickens ’ imaginativeness , or even to Victorian literature . In fact , in the last 400 years , there have been a few hundred report of humans supposedly explode into flaming impromptu – which has now come to be refer to as “ spontaneous human combustion ” ( SHC ) .
Alleged cases of SHC are a author of curio and speculation : the historic lack of a solidscientific explanationhas created a breeding ground for unfounded theories that have bring forth more query than they ’ve answered . The most obvious of these is : is it actually genuine ?

What is spontaneous human combustion?
self-generated combustion takes place when an object rifle up in flaming without an external inflammation source – the blaze is initiated by chemical reactions within the object . Spontaneoushumancombustion is when this supposedly happens inhumans , although , as we ’ll find out , this is almost certainly not what ’s actually bump .
so-called cases tend to have several things in vulgar . They typically demand the body being destroy , while the immediate milieu are impart mostly intact save from a greasy coating on the walls . Not all of the body is ferment to ash , however : some claim that the combustion affects only the torso and that the extremity are left untouched . And , in keeping with its “ spontaneous ” designation , it ’s broadly speaking observe that there is no obvious source of heat that might have start the fire .
Largely , victims fit a interchangeable visibility , being elderly , overweight , socially set apart , and female , and having consume a magnanimous amount of alcohol .

SHC has also , conveniently for those who champion it , never been faithfully witnessed .
Despite skepticism surround its universe , it continues to be accepted in medicolegal configurations and is still sometimes heel as a logical cause of demise . For representative , in 2011 , it wasreportedthat a coroner rule the destruction of a 76 - year - older gentleman in Galway , Ireland , a result of SHC .
All of the mystery cover the phenomenon has led to some fairly kooky theories from its advocates , who have hypothesized everything from poltergeist to “ pyrotrons ” to hear and explicate it .
A history of “spontaneous combustion” in humans
Accounts date stamp back to the 17th century , with a large number documented in the 19th century , and just a handful in the last 100 years .
The first acknowledge case was described in 1641 by a Danish doc and mathematician who recounted the untimely last of an Italian knight in the belated fifteenth century , research biologist Brian J Ford pen forNew Scientistin 2012 . The horse reportedly drank wine one night before mysteriously bursting into flames .
Several other account followed , include those involve inebriant , take to the square-toed hypothesis that SHC was retribution for excessive alcoholic drink phthisis . Dickens himself fanned the flames of this myth , write Krook as an alcoholic .
In 1851 , Justus von Liebig , one of the principal founder of constitutional chemistry , carry on a series of experiments , finding that anatomic specimen stored in 70 percent ethanol do not burn , and nor do rats injected with grain alcohol , thus controvert the alcohol as the solitary cause of the SHC idea .
Without the booze to blame , fingers have been pointed all over the stead , let in at intestinal gas , bio - electrical energy , over - active mitochondria , and even poltergeist , Ford spell in a2012 clause .
However , none of these theories hold much scientific free weight .
A modern explanation?
So what then , if not alcohol or ghosts , could explain this phenomenon ?
“ The most likely explanation is the ' wick effect',”Roger Byard , a Professor of Pathology at the University of Adelaide , told IFLScience .
“ I.e. reclusive alcoholics who are fleshy and wrapped in cover who may run out some of the spirits they are drinking and then drop a lighted butt – all of this results in slow combustion . ”
“ It has been bear witness that a material wick in melted human fat can continue to burn at temperatures as low as 24 ° degree Celsius [ 75 ° F ] , ” Prof. Byardwrote in 2016 . “ [ This ] is proposed as an explanation for the limitation of the size of the fire and the preservation of next trunk parts and clothing . ”
The whole appendage could be worsen by alcohol spill onto apparel , especially if the deceased had been smoke , Byard continued .
The wick effect , brought on by an overlooked international source of ignition system , is presently the prevalent scientific explanation for purported case of SHC , which gives us the answer to our initial doubtfulness :
Is spontaneous combustion in humans real?
“ There is no dubiousness that SHC is a myth , ” Prof. Byard say IFLScience . “ Humans do combust but not spontaneously . That is the reason why no case has really faithfully happen under observation . ”
That ’s not to say that , in exceptional destiny , fervor expiry that have the characteristic feature article of SHC do n’t pass , just that the explanation for these is more mundane than many , a certain Victorian novelist include , would have us believe .
“ There is really no need to evoke the activity of the supernatural , or the potentially explosive effect of undue enteric H , ” Byard concluded in his article . The reality is likely much simple .
