Part 2: BREATHING
People often come to see us with neck and shoulder pain, recurring back pain, core stability issues where the spine never quite feels supported, or more complex presentations such as fibromyalgia.
Why Breathing Matters
Most people don’t think much about how they breathe. It happens in the background, quietly and automatically. But in clinic, breathing often turns out to be one of those small, overlooked things that can have a surprisingly wide effect on pain, tension and recovery, particularly in the neck, shoulders and back. Where breathing may not be the sole cause of their issue, it can still be an important part of the story. In women with fibromyalgia for instance, studies have found altered breathing patterns and reduced thoracic mobility, suggesting the respiratory system may be relevant in assessment and rehabilitation.
That is part of why breathing fits so naturally into the idea that your body is your medicine cabinet. The body already comes with built in systems for regulation, support and recovery. Breathing is one of the clearest examples of that. It is something the body does for us automatically, but it is also something we can influence gently and use to support better function.
The Diaphragm and Supportive Breathing
Breathing should be driven mainly by the diaphragm, the large muscle underneath the lungs. When that system is working well, breathing tends to be quieter, easier and less effortful. When it is not, the body may start relying more on the muscles around the neck, upper chest and upper ribs, and that is often where people begin to feel ongoing tightness, stiffness or fatigue.
The Link Between Breathing and the Nervous System
Breathing is also closely linked to the brain. The rhythm of breathing is coordinated by centres in the brainstem, which help regulate each breath and send that drive to the diaphragm and other breathing muscles. At the same time, breathing sends information back through the nervous system, so there is a constant exchange between the body and the brain. This is one reason breathing can influence more than just the lungs, it can also affect tension, focus, alertness and how settled or guarded the body feels. More recently, we have also been giving breathing exercises to people who are feeling stressed, with the aim of helping regulate the nervous system and support a shift toward a more parasympathetic state, where the body can settle, recover and restore more easily.
There is a two way relationship here. The brain helps drive breathing through the diaphragm, but breathing also feeds information back into the nervous system through sensory and mechanical pathways. Research on breath–brain interaction suggests breathing can influence arousal, attention, emotional state and broader central nervous system activity. In simpler terms, breathing is not just about oxygen. It is also part of how the body gauges whether it needs to stay on alert or whether it can begin to settle.
Breathing and Musculoskeletal Pain
That helps explain why breathing can feel so relevant in musculoskeletal practice. Shallow, upper chest breathing often goes hand in hand with a more guarded or protective pattern in the body. People may feel tighter, more braced and less able to move freely. Slower, more diaphragmatic breathing may help reduce physiological arousal and encourage a shift toward a calmer, less effortful state, which can make movement and recovery easier.
The diaphragm does more than move air in and out of the lungs. It plays a role in trunk support by helping manage pressure through the abdomen and spine. When that system is working well, movement tends to feel smoother and less effortful. When it is not, other muscles may step in and compensate, which can contribute to overload and recurring symptoms.
Breathing, Oxygen and Energy
Breathing also affects chemistry as well as mechanics. How we breathe influences carbon dioxide levels in the blood, and that in turn affects how readily red blood cells release oxygen into the tissues. This is part of what is described by the oxygen–haemoglobin dissociation curve. In simple terms, breathing pattern can influence not only how much air comes in, but also how effectively oxygen is made available where the body needs it. That does not mean every painful or fatigued patient has an “oxygen problem,” but it does help explain why breathing can affect how the whole system feels, especially when someone is already under stress or working harder than they realise just to maintain normal function.
How Treatment Can Help
Hands on osteopathy or physiotherapy can help by improving movement through the rib cage, upper back, spine and surrounding muscles, so breathing feels less restricted and the body is not relying so heavily on the neck, shoulders or other compensating structures. Better rib and spinal mobility can also help the diaphragm work more effectively as part of the wider support system.
Alongside treatment, simple breathing strategies can sometimes help the body shift out of a more guarded, effortful state. The aim is not to make breathing perfect. It is to make it feel less strained, less protective and more supportive of recovery and resilience.
Looking at the Bigger Picture
If something keeps returning and never quite settles, it is not always only about the area that hurts. Sometimes it is also about how the body is organising itself under stress, and breathing can be an important part of that picture.
That is why breathing belongs in this series. It is not an external fix. It is one of the ways the body already helps regulate itself. Sometimes, the role of treatment is simply to help that system work better again.
When to Seek Support
If you’ve been dealing with recurring tension, stiffness or pain that does not seem to fully resolve, it may be worth making an appointment for us to assess whether your breathing, rib movement and upper body mechanics are working together.
