Are Ghosts Summoned by Poor IAQ?
POTSDAM, N.Y.—A team of researchers is examining a possible link between reported ghost sightings and indoor air quality. They say mold can trigger visual and auditory hallucinations. It is known that some fungi, such as rye ergot fungus, may cause psychosis in humans. "Hauntings are very widely reported phenomena that are not well-researched," said Clarkson University associate professor of Civil & Environmental Engineering Shane Rogers. "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. We are trying to determine whether some reported hauntings may be linked to specific pollutants found in indoor air." Rogers' team of undergraduate students plan to measure air quality in several reportedly haunted locations in upstate New York.
