Yang Haiying is a soft-spoken Asian woman with thousands of videos uploaded to her Youtube account. The videos cover a whole bunch of topics ranging from painting to cooking to the making of tea. I’ve only seen her tea-related videos, but she has the kind of voice that will shiver you right up—and she knows it, too. Some of her videos are titled and tagged as “Inadvertent ASMR,” so she definitely knows the power of her sweet voice.

She made her first ASMR video in February 2011, filming herself as she leafed through a journal and played with seashells. The video logged just two views in a month, and Maria was so disappointed that she deleted it. A few months later, she tried again; this time, there were a few encouraging comments. She kept at it, and by the end of the year, she had 30,000 subscribers. Nearly three years later, she has more than 300,000.
Although little research exists on the science behind ASMR, some researchers have theorized how it works. Richard, for one, said ASMR triggers could stimulate the "biological pathways" that humans use when bonding with a romantic partner, close friend, or family member, thus eliciting "similar responses like feeling comforted, feeling relaxed, and feeling secure."
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.[citation needed] 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.[8][9]
