How Breathing Exercises Can Help Relieve Chronic Pain

Over the years, I've worked with many people struggling with chronic pain, back pain, fibromyalgia, tension headaches, neck and shoulder pain that never goes away.

Time and again, I've found one of the most overlooked pieces of the puzzle is something we do around twenty thousand times a day without thinking: our breathing.

I want to be clear from the outset: breathing retraining isn't a cure. Chronic pain is complex, and I'm not suggesting you abandon your other treatments.

But, I've seen dysfunctional breathing patterns quietly feeding into pain in ways most people and many practitioners never consider. Once you understand that connection, you have another real, practical lever to pull.

In this article, I'll walk you through what I've learned about the relationship between breathing and chronic pain, what the research tells us, and how the Buteyko Method can help you build healthier breathing patterns.

What Is the Connection Between Breathing and Chronic Pain?

Breathing and chronic pain feed into each other. It runs both ways.

The diaphragm is the primary muscle of breathing, but that's only half its job. It also helps stabilise your spine, core, and posture, working with the deep abdominal muscles to manage pressure inside the trunk.

When breathing becomes dysfunctional, that stability breaks down and pain often appears in places that seem unrelated to breathing.

Here's what I mean. If you're breathing into your upper chest instead of your belly, your lower ribs are forced to shift, and over time, that can place extra strain on the spine.

When the diaphragm and core aren't doing their job properly, the body compensates by calling on smaller muscles that were never designed to carry that kind of load.

This is where I see chronic pain patterns quietly take root, usually without the person ever suspecting breathing has anything to do with it.

A few patterns I see again and again:

When the nervous system stays switched on like that, breathing shifts to compensate, and that shift often feeds directly into chronic musculoskeletal pain.

There's a 1994 research on trigger points, small, tender knots in muscle tissue that refer pain elsewhere, showing they become more reactive during stressful mental tasks. 

This tells me physical pain and emotional stress are not separate stories. They're the same story, told through the nervous system, with breathing at the centre.

Does Chronic Pain Affect Your Breathing?

Yes, and this is the part people rarely think about. The relationship runs in both directions.

When pain flares, the brain activates the sympathetic nervous system, and breathing rate naturally increases as part of that stress response.

Many people also brace against pain without ever realizing it, holding the breath briefly to guard a painful area or to try to stabilize the spine. Over time, this can settle into a pattern of shallow breathing that rarely relaxes into a full, easy rhythm.

Chronic overbreathing lowers blood carbon dioxide levels, a condition called respiratory alkalosis.

And contrary to what most people assume, carbon dioxide isn't simply a waste gas to be exhaled as fast as possible. It plays an essential role in regulating blood vessel tone and nerve excitability.

When CO2 levels drop too low, it can trigger muscle spasms, constrict blood vessels, and heighten your sensitivity to stress hormones like adrenaline.

Brain imaging research has shown that hyperventilation alters blood flow in the brain's grey matter, a pattern researchers link to widespread constriction of blood vessels as carbon dioxide drops.

Other studies have found that healthy volunteers who deliberately hyperventilated developed pins-and-needles sensations, and eventually muscle spasms, as their CO2 fell further, changes tied to nerve excitability itself, not simply anxiety about the sensation.

For many people living with chronic pain, this shows up as a nagging, hard-to-pin-down feeling that a full breath is somehow out of reach. I call this air hunger, and I see it walk hand in hand with chronic pain more often than most clinicians realize.

Can Fibromyalgia Affect Your Breathing?

Fibromyalgia is, in my experience, one of the clearest illustrations of how deeply breathing and pain are linked.

So, can fibromyalgia affect your breathing? Without question, and often significantly. While working with fibromyalgia patients, I've come to estimate that a significant number of them breathe dysfunctionally in some way.

The research backs this up: around 27% of fibromyalgia patients hyperventilate, and roughly 60% experience dyspnoea, breathlessness. This is exactly why breathlessness and fibromyalgia turn up together so often, and it helps explain why that breathlessness tends to be worse in patients reporting the highest pain levels.

Constant upper chest breathing also aggravates the tender points so common in fibromyalgia, contributing to chest tightness and the fatigue that so often accompanies it.

Because breathing is already compromised in most fibromyalgia patients, the body sits close to a tipping point, even a small further drop in carbon dioxide can be enough to intensify symptoms.

This may partly explain why symptoms often worsen during the luteal phase of the menstrual cycle, a time tied to natural shifts in breathing chemistry.

I want to be careful here, because this is a point I make often, and it matters: faulty breathing does not cause fibromyalgia.

What the research suggests is that it plays a real role in how persistent and severe the condition becomes, which is a very different, and much more useful, claim.

A few studies that have shaped how I think about this:

• An eight-week functional breathing program with 18 fibromyalgia patients led to improved pain tolerance after just one month, along with better sleep quality and duration.
• A 12-week trial involving 35 women with fibromyalgia found significant reductions in pain and fatigue among those practicing daily breathing exercises.
• A follow-up trial of 51 women found that supervised breathing practice offered added pain relief compared with practicing alone, which tells me guidance and correction genuinely matter, not just the exercises themselves.

Can Breathing Exercises Help Relieve Chronic Pain?

Given everything above, the natural question is whether breathing exercises actually help with chronic pain. In my view, the evidence, while still developing in places, is genuinely encouraging.

One study I often point to combined manual trigger point therapy with a specific breathing exercise designed to shift intra-abdominal pressure; every participant experienced reduced pain.

Another study compared diaphragmatic breathing against trunk stabilization exercises in patients with lumbar instability, and the breathing group showed meaningful improvements in rib and sternum mobility, along with better activation of the deep abdominal muscles.

Perhaps the study that has stayed with me most: a 2010 trial looked at patients with chronic back or neck pain who had already tried manual therapy and exercise without success.

Breathing pattern retraining led to improvements in pain and function for the vast majority, 93% achieved a clinically significant change. That's a striking number, and it tells me breathing retraining can help even after other approaches have stalled.

Taken together, here's what I believe breathing work can offer someone dealing with chronic pain:

• Reduced pain intensity
• Better relaxation and lower overall stress
• Improved sleep and daily functioning
• Better quality of life over time

I always frame this the same way: breathing work is a powerful addition to your existing care, not a replacement for it.

Why Diaphragmatic Breathing May Help Reduce Chronic Pain

The diaphragm has two jobs: breathing and stabilizing the spine, and that dual role is exactly why diaphragmatic breathing matters so much for chronic pain.

In a well-functioning body, the diaphragm lowers, and the lower ribs expand outward on the inhale, creating the internal pressure needed to support the spine and pelvis.

However, in people with ongoing lower back problems, I often see the diaphragm sitting higher and flatter than it should, with little rib movement, which limits the body's ability to manage that internal pressure and leaves the lower back less stable.

Research backs up what I see in clinic: people with lower back and sacroiliac joint pain often show early fatigue in the diaphragm itself, likely from years of chronic, effortful overbreathing that wears the muscle down.

Separate research on everyday "load challenges," shoveling snow, pushing a stroller, found that when poor breathing combines with physical demand, postural muscle function drops within as little as 60 seconds.

That's a sobering number, and it underscores just how much dysfunctional breathing impairs the body's ability to move safely under strain. It's also worth noting that back pain is one of the leading reasons athletes miss playing time, and it's frequently tied to these same compensatory patterns.

There's another piece I find fascinating: dysfunctional breathing correlates with increased resting tension in the superficial abdominal muscles.

This creates a bracing effect that feels stabilizing, but actually reduces true core stability, because those muscles aren't working in coordination with the diaphragm.

This, to me, is the real foundation of why breathing through the belly, rather than the chest, helps relieve chronic pain symptoms.

Diaphragmatic breathing appears to work through a few key mechanisms:

• Improving rib and sternum mobility for fuller, more efficient breaths
• Restoring healthier activation patterns in the deep abdominal muscles
• Reducing resting tension in the muscles that overcompensate when the diaphragm is underused
• Supporting better overall regulation of the nervous system

I'll say this plainly: this is not an instant fix. The research, and my own clinical experience, consistently points to consistency over weeks and months as the real driver of change.

How the Buteyko Method May Help People With Chronic Pain

The Buteyko Method takes a different approach to the common advice to simply "breathe deeply." Rather than encouraging bigger, forced breaths, it's built around breathing less, breathing lighter, and breathing through the nose, restoring a healthier balance between oxygen and carbon dioxide.

This distinction matters enormously, because so much of the research I've covered points to overbreathing, and the resulting drop in carbon dioxide, as a key driver of pain sensitivity, muscle tension, and nervous system imbalance.

The core principles I teach are:

• Nasal breathing at rest and during light activity, rather than mouth breathing
• Functional diaphragmatic breathing that uses the belly rather than the chest
• Gentle, reduced breathing exercises that build tolerance to mild air hunger
• Relaxation practices that support the parasympathetic nervous system

By gradually correcting these dysfunctional patterns, the goal is to calm an overactive nervous system, improve tolerance to carbon dioxide, and reduce that sense of air hunger so many people with chronic pain describe.

There's also a link here to the vagus nerve that I find genuinely exciting, even though the research is still early.

One paper proposed that stronger baroreflex stimulation during slow, guided breathing may offer a simple, low-cost way to activate the vagus nerve and help reduce pain, though the researchers were careful to note that this pathway still needs more study, and I share that caution.

Heart rate variability biofeedback research points in a similar direction, showing that training the breath to work in rhythm with the heart can help restore balance to the nervous system.

I want to be clear about one thing: the Buteyko Method is not "take a deep breath." It specifically targets the overbreathing patterns so common in chronic pain, rather than encouraging the large, forceful breaths that can sometimes reinforce the very problem they're meant to solve.

Buteyko Breathing Exercises for Chronic Pain

Here are a few exercises I recommend as a starting point. They're simple, need no equipment, and can be practiced daily.

A quick note before you begin: these exercises are gentle by design and should never leave you gasping or in distress.

If you have a diagnosed respiratory or cardiovascular condition, please check with your doctor before starting, and always practice seated rather than while driving or operating machinery.

Control Pause Check

To get a baseline sense of your current breathing:

• Take a normal, quiet breath in and out through your nose.
• Pinch your nose gently and count the seconds until you feel the first real urge to breathe, the first involuntary swallow, throat twitch, or tightening in the abdomen.
• Release your nose and resume breathing through your nose. This is the key part people miss: your first breath back should be no bigger than your normal breath. If you find yourself gasping or taking a big breath, you've held it too long. That's your signal to ease off next time, not push harder.

Reduced Breathing (Light Breathing)

To build tolerance to carbon dioxide:

• Sit comfortably with your mouth closed and breathe gently through your nose.
• Make each breath slightly smaller than usual, creating a mild, tolerable shortage of air, never a struggle.
• Hold this gentle under-breathing for 1 to 2 minutes, then return to normal breathing.

Breathing Awareness

To notice and correct upper chest breathing:

• Place one hand on your chest and one on your belly.
• Breathe normally and notice which hand moves more.
• Gently guide the breath so your belly hand moves more than your chest hand.

Relaxed Exhale

To support the nervous system:

• Breathe in gently through the nose.
• Let the exhale be slow, soft, and noticeably longer than the inhale.
• Repeat for several breaths, keeping your shoulders and jaw relaxed throughout.

I recommend practicing these once or twice daily, ideally in a quiet moment rather than in the middle of a pain flare. Building the pattern gradually, when your nervous system is calm, tends to produce far more lasting results than trying to reach for it only in an emergency.
