There are two ways that people can experience ASMR. You can experience it through simple meditation or just thinking about a scene or sound that pleases you. Or you can experience it through watching a video or listening to a recording. As for the mechanisms at work behind ASMR, nobody is quite sure why some people react the way that they do. It could be that the videos remind you of your childhood (perhaps, for example, you watched your mom do the same action as a kid, so it’s comforting) or that the simple sounds lull you into a relaxed state.

"We believe technology presents great opportunities for young people to express themselves creatively and access useful information, but we also know we have a responsibility to protect young creators and families and consider the potential impact of emerging trends on them. We've been working with experts to update our enforcement guidelines for reviewers to remove ASMR videos featuring minors engaged in more intimate or inappropriate acts. We are working alongside experts to make sure we are protecting young creators while also allowing ASMR content that connects creators and viewers in positive ways."
ASMR seems to need an emotional component to it, and Winter says that’s not accidental. “Some things may remind you of your mother or being a kid,” he says. “I’d guess that it’s no accident that a lot of the videos of someone whispering feature an attractive woman, which make you think of your mom whispering to you when you went to sleep.” Those memories the videos evoke are likely comforting, and can shift people into a more relaxed state that then helps them fall asleep, he says.
For me it’s tapping, whispering (the closer the better), hair brushing (directly on the mic, not just raking a brush through hair), and hypnosis (even if they’re only attempts or roleplay). Medical or other kinds of roleplay don’t seem to affect me at all and just come off as phony in my mind. It’s the sounds themselves, and their intensity at very close range, that hit me hardest. I don’t really care what’s being said. In fact I get just as much out of asmr in languages I don’t understand. Pretty sure French in and of itself is something of a trigger.
Having previously practiced yoga and meditation for over 10 years, I can induce ASMR at will, or "bliss", as it's called in the spiritual community. It's often part of the very first steps on a spiritual journey, though no requirement. These videos didn't induce ASMR in me though, so maybe it's a different sensation than "bliss", or different triggers.
In 2012, Steven Novella, a neurologist at the Yale University School of Medicine wrote a blog post about ASMR, asking “the most basic question—is it real? In this case I don’t think there is a definitive answer, but I am inclined to believe that it is… 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.” He goes on to speculate as to what ASMR could be—possibly small seizures, or “just a way of activating the pleasure response.”

Autonomous sensory meridian response (ASMR) is a calming, pleasurable feeling often accompanied by a tingling sensation. This tingle is said to originate in a person’s head and spread to the spine (and sometimes the limbs) in response to stimulation. The stimuli that trigger ASMR vary from person to person. Some of the most common ones include whispers, white noise, lip smacking, having a person’s complete attention (as in having one’s hair cut by a hairdresser), as well as brushing, chewing, tapping, scratching, whispering, and crinkling.
1. Do you have different reactions depending on who is the source of the sound? For example, I have very distinctive reactions, i.e. if someone from my relatives does the mouth sounds, I get irritated and at times even angry. I even leave the kitchen if I hear my relatives making the sounds while eating. Purely biological, can’t explain it. The sounds are unpleasant for me. But if a random person or someone I barely know from an opposite sex does the mouth sounds, I can get ASMR or pleasurable feelings.
Some ASMR video creators use binaural recording techniques to simulate the acoustics of a three-dimensional environment, reported to elicit in viewers and listeners the experience of being in close proximity to actor and vocalist.[33] Binaural recordings are usually made using two microphones, just like stereo recordings. However, in binaural recordings the two microphones tend to be more specially designed to mimic ears on humans. In many cases, microphones are separated the same distance as ears are on humans, and microphones are surrounded by ear-shaped cups to get similar reverb as human ears.
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.[15]
