ASMR

How it works

Common triggers are whispering, tapping on wood or glass, crinkling paper, brushing sounds, slow hand movements, and someone paying close, gentle attention, such as at a haircut or an eye test¹. The response is a tingle on the scalp that spreads down the neck and back, sometimes into the arms. It comes with a feeling of calm and sleepiness¹. This makes it different from frisson, which is a fast chill with excitement.

One brain imaging study of 10 people found activity in reward, emotional arousal, and social bonding regions during ASMR². Some of these regions are also active in primates during grooming. One hypothesis is that ASMR is the human version of the calm response to being groomed by a trusted companion¹. This is not proved. A 2018 study found that heart rate falls during ASMR videos in people who feel the response, which fits the calming effect⁴. In one online survey of 475 people who feel it, about half first felt it between ages 5 and 10⁵.

How common it is

Estimates vary widely. A survey of 648 working adults and students found a rate of about 20%⁶. Other estimates reach 60%¹. Some surveys recruit only from online ASMR groups⁵. People who feel nothing rarely take part in these surveys, which likely inflates the figure. No large peer-reviewed study has measured ASMR in a general, unselected population. The wide range likely also reflects differences in how researchers word the question and which triggers they ask about.

Is it a problem?

No. ASMR is not a disorder and not a sign that anything is wrong. Not feeling it is also normal. It differs from frisson, a separate fast-onset chill, and from anxiety, though the calm feeling can resemble drowsiness. There is nothing here to check with a doctor, since it is a pleasant sensation rather than a symptom. Tingling that comes with numbness, pain, or that spreads down one side of the body only, is a different issue and worth mentioning to a doctor.

History and culture

The name was coined in 2010 by Jennifer Allen. She wanted a neutral term to replace earlier names that used the word “orgasm”¹. It is not a medical term. Research began a few years later. Today ASMR is a major video genre with channels that have millions of subscribers¹, and r/asmr is a large community on Reddit³. Anyone can test their own response by watching a trigger video with headphones.
