However, Tony Ro, a professor of psychology and neuroscience at the City University of New York Graduate Center, said in an email that the University of Winnipeg study “is unfortunately not as revealing or informative as it could have been,” given its small size and the fact that researchers were measuring subjects at rest, rather than while experiencing ASMR. The resting state differences could be due to other factors, like higher rates of anxiety or depression, he says. Still, writes Ro, who researches synesthesia and has also been intrigued by ASMR for a few years, “I do think that ASMR may be a form of synesthesia.”
I can trigger it at will, whenever I want with any kind of intensity as I please. I can concentrate the sensation in any place of my body, say tip of a single finger or my whole body. But, I want to know, is it wrong to abuse it? Or is it good? What can happen if I continue using it? By the way, I don’t need external stimuli to activate it, just the desire to do it, it’s like moving your hand.
"Basically, it feels like the amazing chills you get when someone plays with your hair or traces your back with their fingertips," says Heather Feather, a popular "ASMRtist" with nearly 400,000 YouTube subscribers. The dulcet tones of famed soft-spoken painter Bob Ross are among the most common ASMR triggers. Indeed, "Bob Ross" is among the terms most frequently associated with ASMR—and so are "Heather Feather" and "GentleWhispering," another top ASMRtist on YouTube.

ASMR is usually precipitated by stimuli referred to as 'triggers'.[11] ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.[4]
