21 Freaky Facts Too Odd To Be True

#28: Horror Movies: Unseen Fears and Infrasound

Horror movies are a polarizing genre—some revel in the thrills, while others shudder at the thought of watching them. Despite being aware that these films are fictional, the fear they induce can be very real. The eerie music and terrifying costumes are not the only elements at play; there’s another sinister factor involved.

Enter infrasound, a type of sound frequency that often escapes human hearing but can be felt in various ways. Studies have shown that exposure to infrasound can induce anxiety, dizziness, and even heart palpitations. As if horror films weren’t terrifying enough, infrasound adds an extra layer of spine-tingling unease.
