What is 'ASMR' that makes you feel euphoric and relaxed with a tingling sound? Why can't some people experience ASMR?



ASMR , which has become more common in recent years, is an abbreviation for 'autonomous sensory meridian response' and refers to the comfort, tingling pleasure, and relaxed feeling felt by auditory and visual stimuli. On video sites, ASMR videos that trace around a microphone with a makeup brush, scrape soap with a cutter , and whisper in a low voice have become a major genre. Live Science, a science media, explains what ASMR is and why some people cannot experience ASMR.

Julia Poerio, a psychologist at the University of Sussex in the UK, said that while the phenomenon of ASMR varies from person to person, most researchers and enthusiasts agree that the main sensations are 'a tingly sensation that starts in the head and spreads down the spine, and a feeling of euphoria and relaxation. The sensation is like having your hair stroked,' Poerio said.

ASMR is also similar to the ' chill ' feeling some people get when listening to music, but whereas chilling to music makes your heart beat faster and your hair stand on end, ASMR tends to lower your heart rate and slow your breathing.

ASMR is caused by various triggers, and ASMR video creators make people feel ASMR by 'whispering into a microphone' or 'tapping the microphone with a finger or stick.' In addition, according to Poerio, ASMR can be triggered not only by auditory stimuli, but also by tactile stimuli such as 'someone gently brushing your hair.'



However, it seems that simply whispering videos or pleasant tapping are not enough to induce ASMR. Professor

Craig Richard , a physiologist at Shenandoah University in the United States and the owner of the ASMR University website, points out that 'feeling that you are in a safe and calm environment' is also an important factor in experiencing ASMR.

Therefore, ASMR creators make it easier for viewers to feel ASMR by getting familiar with them. In a 2018 study , Richard et al. proposed that many ASMR triggers are related to 'affiliative behaviors' exchanged between people in friendships, parent-child relationships, and romantic relationships.

'If you watch the top ASMR videos, the creators are acting as if they know you really well,' Richards told Live Science. 'It's like tricking your brain into thinking, 'This is someone I know and relate to who is giving me positive, personal attention.''

In this study, Richard and his colleagues used fMRI to find that a part of the brain called the medial prefrontal cortex (mPFC) is activated in people who experience ASMR. The mPFC is responsible for processing and directing social behaviors such as grooming, and because it contains receptors for the hormone oxytocin , which is associated with relaxation and social bonding, the mPFC may be involved in the relaxation effects of ASMR.

Another study has shown that music-induced chill activates the nucleus accumbens , an area of the brain that regulates the brain's ability to respond to stress. This suggests that ASMR and music-induced chill may occur via similar pathways.



Not everyone experiences ASMR, and some people may not feel anything when they watch ASMR videos, so scientists are trying to understand why. 'There's probably a neural basis for people who experience ASMR, in terms of how the brain is formed and experiences earlier in development,' Poerio said.

Some studies have found that people with personality traits such as neuroticism and openness to new experiences are more likely to experience ASMR than those without these personality traits. It's also possible that some people just haven't found the right ASMR trigger yet, so someone who doesn't get ASMR after watching 100 videos might get it after watching the 101st video.
