Just as the reasons vary, so do the triggers. A 2015 study examined ASMR triggers and found that whispering was the most common, with 75% of participants saying it caused body tingles. 64% of participants cited "crisp sounds," like the crackling of foil or tapping of fingernails, as triggers, and 53% said "slow movements," like pouring water, were triggers. Although different people prefer or only react to certain triggers, they typically seek them for the same reason: the physical and emotional side effects.
I experience this occasionally. The strongest occasion was approx 12 years ago. I was in the “High Country” NE Victoria, North of a town called Mansfield. I was out hunting Sambar Deer, 10 K’s from my off sider and in open bush land. About 1 Hr prior I came across droppings from wild dogs which were prevalent in the area and a real problem for farmers. I had this sensation all over my head and down my neck, it scared me. I had the feeling someone, something was watching me and was a bit shaken. I pulled myself together and continued my hunt. Never came across any deer or anything else that day.
You feel quite literally, euphoric, but quite. A moment of deep reflection mixed with an even deeper empathic connection with the subject or sound, And as you grow up, your empahic abilities grow as well, you learn more about the world around you. You may have had a brutal upbringing, You may carry the weight of the world on your shoulders. But you see things differently, you may be gifted, no trauma at all in your life so far, touch wood. For me, it happens while practicing a shared love (graffiti/drawing, in my case) A shared activity (relationships), a menial task (work) or shared adventure (your life), there are so many triggers. I can be alone, an get light empathic feelings for others or even a different race (suffering somewhere in this world), who aren’t even there, I’ll never even meet them. Empathy doesn’t ask permission, it is permission! We are waaaay past that point now people! Spiritually, physically, mentally, we are connected.
While many colloquial and formal terms used and proposed between 2007 and 2010 included reference to orgasm, there was during that time a significant majority objection to its use among those active in online discussions, many of whom have continued to persist in differentiating the euphoric and relaxing nature of ASMR from sexual arousal. However, by 2015, a division had occurred within the ASMR community over the subject of sexual arousal, with some creating videos categorized as ASMRotica (ASMR erotica), which are deliberately designed to be sexually stimulating.
