I attribute it to my son in spirit being present. It didn’t happen to me until after he died. I can’t control it and comes at random times, I’m not able to pinpoint it. It comes in every quadrant of my head at various times of the day and some day’s only a few times. Lately it’s often and much stronger. I thought perhaps because we are within several weeks of first anniversary of his death.
However, the truly novel findings came from a second experiment, when 110 participants viewed ASMR videos while connected to biological feedback machinery. After watching the videos, the heart rates of people with ASMR slowed on average by more than three beats per minute. And their skin conductance levels—a measure of physiological arousal – were significantly increased compared to those in the non-ASMR group.
An article titled "An examination of the default mode network in individuals with autonomous sensory meridian response (ASMR)" by Stephen D. Smith, Beverley Katherine Fredborg, and Jennifer Kornelsen, looked at the default mode network (DMN) in individuals with ASMR. The study, which used functional magnetic resonance imaging (fMRI), concluded that there were significant differences in the DMN of individuals who have ASMR as compared to a control group without ASMR.
Any cursory Googling will bring up videos from the doyenne of ASMR, an Eastern European woman named Maria who goes by the handle GentleWhispering and who constantly sounds like she's on the verge of crying as she attempts to trigger the chills by blowing into a high-tech microphone or folding towels. Her most popular videos have reached over six million views.
Smithsonian: "How Researchers Are Beginning to Gently Probe the Science Behind ASMR" — "The burgeoning Internet phenomenon was so new, it didn’t even have a name. It was so strange and hard to describe that many people felt creepy trying. It resided at the outer edge of respectability: a growing collection of YouTube videos featuring people doing quiet, methodical activities like whispering, turning magazine pages and tapping their fingers. Some viewers reported that these videos could elicit the most pleasurable sensations: a tingling feeling at the scalp and spine, coupled with euphoria and an almost trance-like relaxation.
A: I was just so enamored with the community because it was different than everything else on YouTube then. Everything was very look at me, loud, very grab your attention. I was like, I can’t watch this to relax. The fact that people were putting in the time and effort to make these videos for people to relax, I was like, “That is just so nice! So wholesome! I want to be a part of that community.”
Many of those who experience ASMR report that some specific non-vocal ambient noises are also effective triggers of ASMR, including those like the sound of rain, fingers scratching or tapping a surface, the crushing of eggshells, the crinkling and crumpling of a flexible material such as paper, or writing. Many YouTube videos that are intended to trigger ASMR responses capture a single person performing these actions and the sounds that result.
