Why ASMR makes a lot of noise

ASMR (or Autonomic Sensory Meridian Response) is the tingling sensation that some people experience from certain sounds or images – a ‘brain massage’, in the words of Maria Viktorovna, who has been called the ‘ASMR Queen’. Correspondent Faith Salie talks to Viktorovna about her hugely successful ‘Gentle Whispering’ videos, and to physiology professor Craig Richard, who discusses the physical effects of ASMR. Sage also visits Whisperwave, an ASMR spa in New York City.
