What’s the story behind autonomous sensory meridian response (ASMR) clips?

Researchers at Ruhr University Bochum have published the first systematic review of Autonomous Sensory Meridian Response (ASMR). Millions of people watch content creators on YouTube and social media platforms such as TikTok as they whisper soothing words, perform simulated role plays such as a visit to the hairdresser, or interact with certain objects such as the keyboard of a computer in a specific rhythm.
