Richard, who is also the author of Brain Tingles: The Secret to Triggering Autonomous Sensory Meridian Response for Improved Sleep, Stress Relief, and Head-to-Toe Euphoria, estimates around 20 per cent of the population experience strong ASMR. What triggers people may come down to individual preferences. “The key to triggering ASMR is to create gentle sounds,” he says. Richard’s own triggers include eye exams and [the Netflix series] The Joy of Painting with Bob Ross.
Austrian writer Clemens J. Setz suggests that a passage from the novel Mrs. Dalloway authored by Virginia Woolf and published in 1925, describes something distinctly comparable. In the passage from Mrs. Dalloway cited by Setz, a nursemaid speaks to the man who is her patient 'deeply, softly, like a mellow organ, but with a roughness in her voice like a grasshopper's, which rasped his spine deliciously and sent running up into his brain waves of sound'.
As a penny slid across the concrete porch, it made a pleasant grating sound that, when combined with my uncle’s voice, produced the oddest sensations in me. I felt a “fuzzy” warm sensation inside my skull, as if my brain was floating in a container of heated seltzer water. As my uncle continued to count and slide the pennies, the warm feeling began to extend down my spine and arms. Soon, my entire upper body was cocooned in this warmth and tingling, and I could have listened to my uncle slowly count the pennies for the rest of my life. It was, and remains to this day, one of the most euphoric sensations I have ever experienced.
ASMR has also been called a "brain orgasm" because of gratification it can give viewers, but for the majority of people, there's no sexual connection. A study in PeerJ published in March 2015 found that 98 percent of the 475 study participants used it for relaxation, with 82 percent using it to help them sleep and 70 percent for stress relief. Only 5 percent used it for sexual stimulation, with the vast majority saying it brought no sexual pleasure.
