But the video doesn’t work on me the way it’s supposed to. For many of her fans, Maria’s voice causes a sensation the Internet has dubbed ASMR—autonomous sensory meridian response. Those who get ASMR describe the experience as a tingling inside their heads, or a head rush. Sometimes the sensation extends down their backs or limbs. It’s often referred to as a brain-gasm, but counterintuitively, it’s also supposed to be relaxing, a mellow feeling. Some people watch the videos to help them sleep at night. And even without the tingles, it is sort of relaxing, if you can get past the dissonance of someone whispering in your ear while you scroll through Twitter in your cubicle, or whatever.
The most popular source of stimuli reported by subjects to be effective in triggering ASMR is video. Videos reported being effective in triggering ASMR fall into two categories, identified and named by the community as 'Intentional' and 'Unintentional'. Intentional media is created by those known within the community as 'ASMRtists' with the purpose of triggering ASMR in viewers and listeners. Unintentional media is that made for other purposes, often before attention was drawn to the phenomenon in 2007, but which some subjects discover to be effective in triggering ASMR. One early unintentional example is the Art Bears song 'The Bath of Stars.' Another example of unintentional media several journalists have noted is of famed painter Bob Ross. In episodes of his popular television series The Joy of Painting both broadcast and on YouTube, his soft, gentle speaking mannerisms and the sound of him painting and his tools trigger the effect on many of his viewers. The work of stop-motion filmmaker PES is also often noted.
