According to YouTube estimates, there are more than 45 million ASMR videos uploaded to the site, and, over the past year, there has been a marked increase in children making ASMR-related videos. Richard hypothesises that our brain is probably more receptive to an unknown child than a strange adult, making it easier for some individuals to be relaxed by ASMR videos featuring children.
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.
