ASMR

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 ..

Stimuli that can trigger ASMR, as reported by those who experience it, include the following:

Listening to a softly spoken or whispering voice.
Listening to quiet, repetitive sounds resulting from someone engaging in a mundane task such as turning the pages of a book.
Watching somebody attentively execute a mundane task such as preparing food.
Loudly chewing, crunching, slurping or biting foods, drinks, or gum.
Receiving altruistic tender personal attention.
Initiating the stimulus through conscious manipulation without the need for external video or audio triggers.
Listening to a person explain a concept, describe an object or system.
