Summary: Autonomous Sensory Meridian Response (ASMR) is a widely viewed phenomenon that many people use to relax, fall asleep, or improve mood. A comprehensive review of the scientific literature finds consistent short-term benefits for a subset of the population—about 25–30%—including measurable physiological changes such as reduced heart rate and lower blood pressure.
After screening more than 1,000 records, researchers identified 54 peer-reviewed studies that met inclusion criteria. These studies converge on a common description of the ASMR experience and identify reproducible neurophysiological patterns tied to the phenomenon, including altered electrophysiological signals and activation of specific brain regions. At present, there is no clear evidence for lasting mental health effects from ASMR, and researchers are planning controlled, longer-term studies to test sustained impacts.
Key Facts:
- ASMR produces short-term improvements in mood and measurable physiological responses (e.g., slower heart rate, reduced blood pressure) for about one quarter to one third of people.
- Electroencephalography (EEG) studies suggest ASMR is linked with reductions in delta-wave activity, and functional MRI (fMRI) studies highlight engagement of the anterior cingulate gyrus and motor-related brain regions.
- Researchers are developing longer-term intervention studies that will compare ASMR videos to neutral control footage (for example, “walking tour” recordings) to determine whether benefits are sustained over time.

Many viewers find ASMR videos calming and useful for unwinding or sleeping, although a minority report irritation from the same content. To better understand ASMR, the research team applied systematic review methods to existing empirical studies, isolating 54 quantitative investigations with a combined sample of more than 11,000 participants. That body of work makes it possible to summarize what is reliably known about ASMR to date.
Tobias Lohaus, one of the review authors, explains that the ASMR experience is described in very similar terms across diverse individuals and does not appear to be solely the product of expectancy effects among regular viewers. For people who report experiencing ASMR—roughly 25–30% of survey respondents—viewing ASMR content is reliably associated with short-term emotional relief and physiological signs of relaxation.
On the neurophysiological level, EEG evidence has repeatedly pointed to decreases in delta-band activity during ASMR episodes. While delta waves are commonly linked to deep sleep, they are also associated with particular states of consciousness; researchers speculate that these delta reductions may reflect a relaxed but awake state characteristic of ASMR. Complementary fMRI research highlights activation in the anterior cingulate gyrus and motor-related regions, suggesting a network that involves attention and sensorimotor processing during ASMR experiences.
Planned studies to examine long-term effects
Despite consistent short-term findings, the review emphasizes that no high-quality study has yet demonstrated long-term mental health benefits from ASMR. Establishing such effects will require randomized, controlled trials that track outcomes over weeks or months and compare ASMR interventions with appropriate control content. The research teams at Ruhr University Bochum and the University of Duisburg-Essen are preparing proposals for such work.
The authors note a promising approach: earlier work from the same group identified “walking tour” videos—first-person recordings of walks through public spaces—as potential control stimuli. These walking-tour clips elicit significantly less ASMR response than dedicated ASMR recordings, making them useful comparators for future intervention studies.

Abstract (rephrased)
Autonomous Sensory Meridian Response (ASMR): A PRISMA-Guided Systematic Review
This systematic review followed PRISMA guidelines to synthesize quantitative research on ASMR. Searches of major bibliographic databases up to March 2022 produced 54 eligible studies, representing a combined participant pool of approximately 11,140 individuals. Across studies, ASMR correlates with several mental-health–related outcomes—most notably short-term improvements in mood—as well as certain personality characteristics. Neurobiological findings include altered electrophysiological patterns (notably tentative decreases in delta activity), activation of specific brain regions such as the anterior cingulate gyrus and motor-related areas, atypical functional connectivity patterns in some reports, and physiological signs of relaxation like heart rate reduction. The review concludes that future research should broaden psychological constructs investigated, refine neurobiological measurements, and conduct long-term intervention trials to determine whether ASMR can produce sustained mental health benefits.
