ASMR: what we know so far about this unique brain phenomenon – and what we don't

ASMR is an emotional state that some people experience when they hear, see, and feel certain "triggers," such as whispering, delicate hand movements, and light touch.

The feeling is described as a tingling sensation that starts from the top of the head and spreads down the neck and limbs. Feelings of euphoria and relaxation accompany this "trance-like" state.

ASMR typically emerges in childhood. When people find out that ASMR is a "thing", they often report that they thought everyone had the same experience or that it was unique to them.

Common triggers include soft touch, whispering, soft-speaking, close attention, delicate hand movements, and crisp sounds. Situations that induce ASMR are often a combination of these triggers, such as getting a haircut or watching someone complete a mundane task.

One study showed that periods of ASMR tingling were associated with increased activation in brain regions involved in emotion, empathy, and affiliative behaviors.

Other studies show that people with ASMR have less distinct and more blended neural networks, suggesting that ASMR could happen because of a reduced ability to suppress emotional responses that we obtain from our senses.

Research suggests that people who experience ASMR have a larger tendency to have more immersive or absorbing experiences.

People with ASMR score higher on 'openness to experience,' reflecting imagination, intellectual curiosity, and appreciation of art and beauty. People with ASMR are also more empathetic when looking at compassion and concern for others.

People with ASMR show significant reductions in their heart rates when watching ASMR videos.

These stress reductions were similar to those experienced during mindfulness and music therapy. But research is not clear whether ASMR can and should be used as an effective form of therapy.
