Does the sound of Bob Ross‘s paintbrush scratching against the canvas send shivers down your spine? Does hearing scissors snip away at your hair make your brain feel tingly? It might be ASMR.
ASMR, short for autonomous sensory meridian response, is often described as a pleasant tingling sensation that starts on the scalp and moves down the neck and spine upon hearing certain sounds. Those who experience it sometimes call the sensation a “brain orgasm,” but don’t get weirded out—the response is non-sexual.
