“The strongest type of tingle…feels like sparkles or little fireworks going off,” she says. “The strongest one would give you the feeling of being exhausted, pleasantly tired, satisfied almost you want to say. Then there are much less strong tingles, and they feel just pleasant. Almost like sand is being poured down your spine. [Or] like when you get the funny elbow, when you hit it and it feels like it just goes off everywhere.”
My main trigger is watching someone concentrating silently on a mundane task (writing, drawing, ironing, cleaning, doing a puzzle) and them not being aware that I am aware of what they are doing. I also find sometimes that having a haircut can produce the same sensation. I also find that the feeling can sometimes be accentuated by gently rubbing the back of my neck with something like a pen or the end of my glasses. I haven’t yet found a video that works as a trigger – it needs to be there for real and even then doesn’t and won’t happen “on demand”.

wow. I never knew what that feeling was called until now. I’ve kept it to myself all of these years because I was never sure how to talk about it. I discovered mine in kindergarten when a girl traced her finger along a page. I can experience ASMR pretty much whenever I want now. for me, it’s a combination of sound and motion. for some reason, an Indian accent triggers it very easily. it’s an amazing feeling. I’m curious, does anyone know if there are any health pros or cons with ASMR? have any studies been done?

A few weeks ago, Maria says, she was contacted by a young woman whose grandmother was in a hospice. The elderly woman was no longer very responsive, but when the granddaughter played Maria’s videos, “it made her grandmother happy and calmed her down,” Maria says, recalling the woman’s message. “She said, ‘This is so great, because we don’t know how else to help her.’ ”
Barratt and Davis don’t see their study as a complete story; rather, it’s a foot in the door for researchers interested in studying the phenomenon. “We hope our work will provide a platform for more sophisticated work in the future, but we saw it as a starting point,” explains Davis. The next step, ideally, is to start trying to pin down the physiological basis of the sensation.
On 12 March 2012, Steven Novella, Director of General Neurology at the Yale School of Medicine, published a post about ASMR on his blog Neurologica. Regarding the question of whether ASMR is a real phenomeonon, Novella said "in this case, I don't think there is a definitive answer, but I am inclined to believe that it is. There are a number of people who seem to have independently experienced and described" it with "fairly specific details. In this way it's similar to migraine headaches – we know they exist as a syndrome primarily because many different people report the same constellation of symptoms and natural history." Novella tentatively posited the possibilities that ASMR might be either a type of pleasurable seizure, or another way to activate the "pleasure response". However, Novella drew attention to the lack of scientific investigation into ASMR, suggesting that functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation technologies should be used to study the brains of people who experience ASMR in comparison to people who do not, as a way of beginning to seek scientific understanding and explanation of the phenomenon.[39][40]

The story follows Tom More, a psychiatrist living in a dystopian future who develops a device called the Ontological Lapsometer that, when traced across the scalp of a patient, detects the neurochemical correlation to a range of disturbances. In the course of the novel, More admits that the 'mere application of his device' to a patient's body 'results in the partial relief of his symptoms'.[20]
