The video was designed for people who experience “ASMR”. Short for “autonomous sensory meridian response”, ASMR is a euphoric feeling certain people get from specific auditory stimuli. Those who experience it have different triggers – such as whispering, chewing or tapping – and also experience different bodily responses; some feel tingles, others become incredibly relaxed.
ASMR doesn’t work for everyone and it can be tough to imagine the sensation if you don’t experience it first-hand. For most people who do experience it, the blissful tingling starts up in the scalp and then makes its way through the body to the arms and legs. And as a result, it can trigger a feeling of relaxation before bedtime, which can help you overcome insomnia. The audio/video segments are long—in fact, some last up to an hour. They are lengthy so that you can keep watching or listening to them until you drift off.
Nothing can currently be definitively known about any evolutionary origins for ASMR since the perceptual phenomenon itself has yet to be clearly identified as having biological correlations. Even so, a significant majority of descriptions of ASMR by those who experience it compare the sensation to that precipitated by receipt of tender physical touch, providing examples such as having their hair cut or combed. This has led to the conjecture that ASMR might be related to the act of grooming.
Why does this exist? Because some people experience ASMR, aka autonomous sensory meridian response, a condition that means certain sounds cause you to experience a pleasant, tingly feeling on your scalp, or around the top of your spine. Sounds weird, has in fact been around for a while – by late 2016, approximately 5.2 million ASMR videos had been uploaded to YouTube.
I’m a prematurely retired, disabled, UCLA med school trained pediatrician, due to a stroke and for me ASMR occurs only with music, but just what I call exquisite(level) music. Interestingly before my love for science, my first love was music, as an alto, tenor, and baritone sax player as a child. My experience is that it always is full body, at the onset, and sometimes is accompanied by a slight body warmth effect. It is always a very pleasant sensation, and does not always occur with these level of songs. Not maybe related, but I’ve become a sensation at party type celebrations, as people are amazed at my dancing skills without my quad cane, without much use of my limited right side of my body. They look at me in a crazed way when I tell them I really don’t consider it dancing, in the strictest sense, but it’s like the music and I are symbiotic, and I become the music so that my body just starts spontaneously moving in such a way they would not believe possible, with much improved balance, as people start to hoot, holler, clap and recording with their smart phones. I’m not putting on a show, just enjoying music at the highest level I know. I have always loved music intensely. Initially, I did what I call chair dancing, all upper body, for quite some time, after my stroke.
One category depends upon external triggers in order to experience the localized sensation and its associated feelings, which typically originates in the head, often reaching down the neck and sometimes the upper back. The other category can intentionally augment the sensation and feelings through attentional control, without dependence upon external stimuli, or 'triggers', in a manner compared by some subjects to their experience of meditation.
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.
