Turning Down the Volume: What Brain Scans Reveal About Why Massage Works
By Ramsey Rumig, Registered Massage Therapist (RMT) and founder of Blue Mountain Wellness. Serving Collingwood, Thornbury, and The Blue Mountains.
Here is something that surprises most of my clients: the most interesting thing a massage does might not happen in your muscles at all. It happens in your brain.
For a long time, the story we told about massage was a plumbing story. Tight muscle, knead the knot, release the tension, done. That story isn't wrong, exactly, but it turns out to be the least interesting part of what's going on. Over the past few years, researchers have started putting people in brain scanners before and after massage, and what they're finding reshapes how I think about the work I do in living rooms and chalets across South Georgian Bay.
Your brain has a volume knob for pain
Start with the idea that pain is not a simple reading from your body, like a fuel gauge. Pain is something your brain produces, a decision it makes about how much danger a signal represents. And crucially, your brain can turn that signal up or down.
There's a small structure deep in the brainstem called the periaqueductal gray. Think of it as the volume knob for pain. When it's engaged, it sends signals downward that quiet the pain traffic coming up from your body. This is why a soldier can be badly hurt and feel nothing until the danger passes, and why stress and poor sleep can make an old ache scream. Same body, different volume setting.
The new research suggests that massage reaches up and turns that knob down.
What the brain scanners are actually showing
A 2025 review pulled together forty-seven studies that measured brain activity during or after hands-on massage, using three different technologies: EEG (which reads electrical rhythms), fMRI (which maps blood flow to active brain regions), and fNIRS (which reads oxygen use near the surface of the brain). Three different windows into the same room. Here's the plain-English version of what they saw.
The brain shifts into a calmer gear. On EEG, massage reliably increased alpha waves — the electrical rhythm associated with a relaxed, settled mind — while quieting the faster, busier rhythms of a brain on alert. In people dealing with pain specifically, the brain's activity slowed and simplified in a way that tracked with their relief. The calmer the rhythm, the less the pain.
The pain-control centres light up. On fMRI, massage engaged exactly the regions you'd hope for, including the insula, the anterior cingulate, and that periaqueductal gray — the volume knob itself. The brain's own pain-dampening machinery switched on under a therapist's hands.
The wiring starts to normalize. This is the part I find most compelling. In people with chronic pain, repeated massage sessions were associated with the brain's networks re-balancing toward a healthier pattern — and that shift moved in step with their symptoms improving. Not a one-session flush, but a slow retuning over weeks.
The chemistry backs it up. fNIRS studies, paired with blood markers, linked these changes to increased activity in the calming branch of your nervous system, lower cortisol, and oxytocin — the same affiliative chemistry involved in safe, trusted human touch.
Put simply: moderate-pressure, skilled massage appears to talk directly to the parts of your nervous system that decide how much pain, tension, and stress you're going to feel. It's less like fixing a pipe and more like resetting a thermostat.
An honest word about the evidence
I'd be doing you a disservice if I oversold this. This is a young, exciting field, not a closed case. The studies are small and they vary a lot in method — enough that the researchers couldn't even combine them into a single statistical result. What we have is a set of converging signals all pointing the same direction, which is genuinely encouraging, but it's not the same as ironclad proof. Massage is a powerful support for pain, stress, and recovery. It is not a cure, and anyone who promises you one is selling something. What the brain research does is help explain why so many people feel so much better afterward — and why that feeling is real, not just "in your head." Or rather: it is in your head, in the most literal and legitimate sense.
Why this matters for a massage at home
Here's where it gets practical for those of us up here in ski-and-cottage country. If a big part of massage's value is coaxing your nervous system out of high alert, then where you receive it matters. A brain trying to settle in an unfamiliar clinic, after a drive, in a paper-gowned waiting room, is fighting a small headwind the whole time.
When a Registered Massage Therapist comes to your home, chalet, or Airbnb in Collingwood, Blue Mountain, or Thornbury, you're already in the one place your nervous system reads as safe. No drive there, no rush home while you're still floating. You lie down in your own space, and there's no re-tensing on the way out the door. If the goal is to turn the volume down, it helps to start in a quiet room.
Frequently asked questions
Does this mean massage is "all in my head"? In a sense — but that's the opposite of dismissive. Your brain is where pain is actually generated and regulated, so a therapy that measurably changes brain activity is working on the real control centre, not a placebo.
How many sessions before I'd notice a change? Many people feel the acute, calming effect after a single session. The deeper network changes seen in chronic-pain research happened over repeated sessions across several weeks — consistency matters more than intensity.
Is deep, hard pressure better for this? Not necessarily. The relaxation and pain-quieting effects in the research were most consistent with moderate pressure. More pressure isn't automatically more benefit — and a good therapist tunes it to you.

Ready to give your nervous system a reset?
You don't need to understand your periaqueductal gray to benefit from settling it — you just need a quiet room and a skilled pair of hands. If you'd like to feel what the brain scanners are describing, I'd be glad to bring the table to you.
