Spontaneous combustion is a combination of complex chemical reactions that are the subject of research worldwide and that are not yet fully understood. The likely explanation for suspected cases of spontaneous human combustion, then, is that there is an external source of ignition—a match, a cigarette, an electrical spark—that sets off the wick effect, but the evidence of it is destroyed by the fire.
