Spontaneous Human Combustion (SHC) refers to a mysterious phenomenon in which the human body, living or recently deceased, may spontaneously combust without an apparent external ignition source. The concept has captured public attention since the 18th century, but its scientific basis is controversial. Throughout history, several cases of death from spontaneous combustion have been recorded, and these cases seem to have similar characteristics, prompting people to think deeply about this phenomenon.
More than 200 cases of spontaneous combustion have been documented, occurring around the world over a period of approximately 300 years.
Early studies have shown that spontaneous combustion is associated with certain groups of people. For example, the victims are often elderly women with chronic alcohol addiction, and it is often found that the surrounding combustible items have been minimally damaged when the incident occurs. This trend has attracted the attention of the scientific community, and many scholars have begun to explore the potential causes and mechanisms.
In a two-and-a-half-year study, scientists conducted an in-depth investigation of 30 historical cases between 1725 and 1982. They determined that the circumstances surrounding death were often associated with proximate fire sources, such as candles, oil lamps, and fireplaces. The findings suggest that these potential external fire sources are omitted from many reports, adding to the mystery surrounding spontaneous combustion deaths.
Studies have linked spontaneous combustion deaths to the victims' state of intoxication, which may prevent them from reacting properly when an accident occurs.
The current scientific consensus is that most so-called spontaneous combustion phenomena are caused by external fire sources, and spontaneous combustion without external fire sources is extremely unlikely. Various natural causes have also been proposed to explain these incidents, such as a heart attack that could have caused the victim to lose consciousness while smoking, which in turn caused the fire.
Some scholars have proposed the "candle effect" hypothesis, that is, a small external fire source can trigger flesh combustion, and this combustion can continue as long as there is enough fuel.
There are several famous cases of spontaneous combustion in history. For example, in 1951, 67-year-old Mary Reese was found reduced to ashes with only one leg left. The investigation at the time believed that she may have accidentally caught fire while smoking. A similar case occurred in Dublin in 1970, when 89-year-old widow Margaret Hogan was burned almost completely while her surroundings were barely damaged, a situation that is difficult to explain.
The phenomenon of spontaneous combustion has long been a subject of literature and the media. In many novels, it is not uncommon for characters to die from spontaneous combustion. For example, references to the phenomenon in Charles Dickens' Bleak House and Melville's The Red Circle have made spontaneous combustion a part of many cultures, prompting further exploration and debate of this mysterious phenomenon. theme.
Whether humans can spontaneously combust without any external influence has never been determined in the scientific community. With the advancement of technology and research, perhaps one day we will be able to get to the bottom of the mystery. What will people think of this mysterious phenomenon?
