Spontaneous human combustion (SHC) refers to the alleged phenomenon where a person suddenly bursts into flames without an external ignition source, often leaving behind severely burned remains while surroundings remain largely untouched. Documented for centuries in folklore and medical literature, these cases blend gruesome detail with inexplicable circumstances, challenging both skeptics and believers to reconcile anecdotal evidence with scientific principles.

Historical records include chilling cases like that of Mary Reeser (1951), whose Florida apartment contained only her skull fragments, a vertebra, and a foot—all amid ashes—yet a nearby newspaper remained unburned. Similarly, Irishwoman Mary Hardy (1744) was reportedly reduced to ash in her home, leaving only her legs and chair intact. Charles Dickens even featured SHC in Bleak House, using it to symbolize moral decay.

Modern science offers plausible theories, primarily the "wick effect." This suggests that once ignited by a external source (e.g., cigarette, candle), the body’s fat can act like candle wax, burning slowly due to melted fat saturating clothing and skin. This process may explain why victims’ torsos are often consumed while extremities remain—the fire burns inward, fueled by body fat, while limbs lack sufficient fuel. Conditions like obesity, alcoholism (which may impair mobility), and proximity to heat sources (e.g., space heaters) often feature in cases.

Yet mysteries persist: Why are surrounding objects so rarely damaged? How do temperatures reach the extreme heat needed to cremate bone (≈1600°F)? Some propose rare metabolic or electrical phenomena, but no evidence confirms true spontaneity.

Forensic experts emphasize that suspected SHC cases typically reveal overlooked ignition sources upon investigation. Nonetheless, the myth endures due to its visceral horror and the unsettling idea that our bodies could betray us so violently. SHC remains a cautionary tale about the line between legend and science—a reminder that even in an age of enlightenment, some stories resist easy explanation.
