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.
ASMR is usually precipitated by stimuli referred to as 'triggers'. ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.
