For years, reports of ghostly encounters have captured public imagination. People often describe feelings of unease or anxiety in settings purported to be haunted. These experiences have largely been attributed to folklore and cultural beliefs.
Recent research has introduced an unexpected factor. Scientists found that low-frequency sounds, termed infrasound, which are below 20 Hz, may influence emotional states. The study indicates that exposure to infrasound can elevate cortisol levels in saliva, a hormone linked to stress.
The research involved subjects in controlled environments where they were exposed to varying levels of infrasound. Findings showed a marked increase in irritability and discomfort among those exposed. As participants reported heightened anxiety, parallels emerged with descriptions of paranormal experiences.
This revelation redefines our understanding of ghostly phenomena. It suggests that physiological reactions could underpin feelings commonly associated with hauntings. The implications extend beyond folklore, prompting deeper investigations into environmental factors influencing human psychology.
