How ASMR Affects the Brain
Here is what the research actually shows: in small lab studies, people who get ASMR feel calmer, their heart rate drops, and brain scans light up in areas linked to reward and emotion. That is the whole confirmed list. Most of what you read online about why it happens is a hypothesis, not a finding, and this page labels which is which.
What have studies measured so far?
Three studies give the clearest picture, and all of them are small.
| Study | What they did | What they found | What it did not test |
|---|---|---|---|
| Poerio and colleagues, 2018 | One large online experiment and one lab study | ASMR videos raised pleasant mood only in people who get ASMR. In the lab, ASMR came with a lower heart rate and higher skin conductance. | Long-term effects, sleep, or any health condition |
| Lochte and colleagues, 2018 | Brain scans (fMRI) of 10 people prescreened for ASMR | Activity in areas tied to reward and emotional arousal, similar to patterns seen with music chills and bonding behavior | People who do not get ASMR, or what the activity means for health |
| Sakurai and colleagues, 2023 | Brain scans of 30 ASMR fans watching videos they liked and disliked | Emotion-related areas activated only for videos the person liked | Whether liked videos improve anxiety or depression in real patients |
If you want one takeaway: the effect shows up in people who already respond to ASMR, and it depends on the video matching their taste.
Why do only some people feel it?
Nobody knows yet. Poerio's study found the mood lift only in people who reported getting ASMR, so non-responders watching the same video felt no change. No study has explained what makes someone a responder.
If you have never felt tingles, you can still use ASMR videos as quiet background sound. Just don't expect the mood effects the studies describe.
Why does the trigger matter so much?
Sakurai's 2023 study is the most useful one for listeners. Emotion areas responded to videos people liked and stayed quiet for ones they disliked. The study did not test sleep or anxiety, but it backs a practical rule: a trigger you dislike is not doing anything for you.
If a video irritates you within the first minute, switch to a different trigger type rather than waiting it out.
What is still a hypothesis?
Several popular explanations have not been tested directly:
- The care signal idea. One idea is that soft, close sounds mimic being looked after, which is why personal attention roleplays are common. Lochte's scans found similarities with bonding behavior, but that is a resemblance, not proof of cause.
- The near-touch idea. Flockton and colleagues proposed in 2025 that close-up sounds like brushing and whispering lead the brain to expect gentle touch on the scalp and neck. Their survey of 64 people found ASMR clips felt more pleasant than controls, and more pleasant clips went with stronger tingles. The rest of their model is a set of predictions still waiting for tests.
Treat any article that states these ideas as settled fact with suspicion.
What should you do with this?
Use ASMR for what the evidence supports: a short, pleasant calming session if you respond to it. Pick triggers you like, keep the volume low, and stop any video that annoys you. ASMR is not a treatment; talk to a doctor if symptoms of anxiety or poor sleep persist.
Frequently asked questions
Does ASMR release dopamine?
No study has measured dopamine during ASMR. Brain scans by Lochte in 2018 and Sakurai in 2023 found activity in areas linked to reward and emotion, and Sakurai's team suggested a dopamine link as a possible explanation. A brain area lighting up on a scan is not the same as measuring a chemical, so treat dopamine claims as unproven.
Is ASMR the same as music chills?
They look related but are not identical. Lochte's 2018 scan study saw brain activity during ASMR that resembled patterns previously seen with music chills. Poerio's 2018 study found ASMR came with a lower heart rate, which sets it apart from the more excited feel people describe with chills. Both studies were small.
Can ASMR harm your brain?
No study reviewed for this page reported harm from watching ASMR videos. The practical risks are ordinary ones: loud volume through headphones and lost sleep from scrolling at night. Keep the volume low and use a sleep timer if you listen in bed.
Quick tips
- If a video makes you tense in the first minute, close it and try a different trigger type instead of forcing it.
- Treat any article that says ASMR rewires your brain or treats a condition as marketing until it names a study.
- Use ASMR as a short wind-down habit before bed, and keep the volume low enough that sudden sounds cannot jolt you.
