There are many hypothesized explanations which account for the various cases of spontaneous human combustion. These generally fall into one of three groups: paranormal explanations ( a ghost or alien caused it), natural explanations that credit some unknown and otherwise unobserved phenomenon ( the production of abnormally concentrated gas or raised levels of blood alcohol cause spontaneous ignition), and natural explanations that involve an external source of ignition.
