Pica, according to the U.S. National Library of Medicine, is when an individual craves materials that can’t strictly be considered “food” for a period that’s longer than a month. This could include chalk, but also materials like clay, sand, dirt, glue, paper, and pretty much any other material you can imagine. It’s common in children, but it also occurs in teens and adults with unknown prevalence.
You can kind of understand why. To people who don't experience ASMR, the videos can rightly look completely ridiculous. Also, because a sense of intimacy can be a very powerful trigger, it's no surprise that some of the best artists are very attractive girls, and there's clearly some personal security risks when you're putting your face out there and developing strange online relationships with people who might start to rely on a false sense of intimate connection with you.
I, too, have a hair-trigger tear response to anything touching, which is displayed to me cinematically, and is nearly always accompanied by the tingles. I am touched by things that I think other people would find odd, however, like the concept of reincarnation, or psychic phenomena, or anything gently sexual and romantic. Most especially scenes like those in “The Blue Lagoon,” where the kids grow up, and discover each other as sexual beings, in innocence and freedom, tend to touch my heart most, and cause emotion and tears to well up.
I can trigger it at will, whenever I want with any kind of intensity as I please. I can concentrate the sensation in any place of my body, say tip of a single finger or my whole body. But, I want to know, is it wrong to abuse it? Or is it good? What can happen if I continue using it? By the way, I don’t need external stimuli to activate it, just the desire to do it, it’s like moving your hand.
ASMR, or “autonomous sensory meridian response,” is the term for the sensation people get when they watch stimulating videos such as this one. Many people describe the feeling as “tingles” (or “head orgasms“) that run through the back of the head, neck, and, spine. For some, the feeling is deeply relaxing and can even cause them to fall asleep. This is definitely not something I experienced.
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'.
In addition to the effectiveness of specific auditory stimuli, many subjects report that ASMR is triggered by the receipt of tender personal attention, often comprising combined physical touch and vocal expression, such as when having their hair cut, nails painted, ears cleaned, or back massaged, whilst the service provider speaks quietly to the recipient. Furthermore, many of those who have experienced ASMR during these and other comparable encounters with a service provider report that watching an "ASMRtist" simulate the provision of such personal attention, acting directly to the camera as if the viewer were the recipient of a simulated service, is sufficient to trigger it.
