I have repeatedly tried listening to ASMR YT videos, however, I have found them actually highly irritating and not calming. The whispering (extreme soft speaking) cause me great annoyance. You are right in that not all people respond to ASMR videos in the same manner. However, a back massage with calming music, listening to powerful worship music, dialogue of a spiritual nature, sitting by water and meditation on Scripture are triggers for this sensation.
The term ASMR was coined in 2010 by Jennifer Allen, a 39-year-old penetration tester. “For years I thought, ‘Jeez, maybe I have a brain tumour or something,’” she recalls. From 1999 onwards, Allen searched steadfastly for others like her online. In the late noughties, she stumbled upon a SteadyHealth.com forum in which a user named okaywhatever51838 discussed a “weird sensation” that “feels good”.
ASMR is usually precipitated by stimuli referred to as 'triggers'. 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.
