A team of Clarkson University researchers is studying the possible links between reported hauntings and indoor air quality.
Associate Professor of Civil & Environmental Engineering Shane Rogers said human experiences reported in many hauntings are similar to mental or neurological symptoms reported by some individuals exposed to toxic molds. It is known that some fungi, such as rye ergot fungus, may cause severe psychosis in humans.
The links between exposure to toxic indoor molds and psychological effects in people are not well established, however, Rogers said. Notably, many hauntings are associated with structures that are prime environments to harbor molds or other indoor air quality problems.
“Hauntings are very widely reported phenomena that are not well-researched,” he said. “They are often reported in older-built structures that may also suffer poor air quality. Similarly, some people have reported depression, anxiety and other effects from exposure to biological pollutants in indoor air.
