How to breathe correctly (and why it matters for your neck pain)
Most people are breathing incorrectly.
Not badly. Not dangerously. Just in a way that’s quietly keeping their nervous system in a threat state and making their neck and shoulder tension worse.
Here’s how.
The mechanics first
Your diaphragm is the primary muscle of breathing. It’s a dome-shaped muscle that sits at the base of your ribcage. When it contracts, it flattens downward and your belly expands. That’s a proper breath.
When you’re stressed, anxious, in pain, or just habitually tense, your diaphragm stops doing most of the work. Instead, your accessory breathing muscles take over — your scalenes, your SCM, your upper trapezius. These are the muscles in your neck and upper shoulders.
If you’re breathing that way all day, every day, those muscles never get to rest. They are literally working with every single breath you take. That’s why neck tension comes back no matter what you do. You haven’t addressed the breathing pattern driving it.
The neck-breath connection
The scalenes are a group of muscles on the sides of your neck. They run from your cervical vertebrae down to your first and second ribs. One of their jobs is to lift the ribcage during inhalation — a secondary breathing function that becomes primary when you’re a chest breather.
If you’re breathing shallowly through your chest all day, your scalenes are working constantly. Chronically overworked muscles become tight, tender, and eventually they start compressing things. The brachial plexus — the nerve bundle that runs through the scalenes down into your arm — can get compressed. That’s where the arm tingling comes from.
Your upper traps are doing similar work. Lifting your shoulders slightly with every breath, staying chronically activated, contributing to the pattern of shoulder tension that never fully releases.
This is a structural consequence of a neurological pattern. Breathing wrong isn’t just a habit. It’s a symptom of a nervous system running in threat mode — and it causes real physical problems.
How to breathe correctly
Belly breathing, not chest breathing. When you inhale, your belly should expand first. Not your chest, not your shoulders. Your belly out, then your lower ribs expand, then maybe your chest very slightly at the top. When you exhale, the reverse — chest down, ribs in, belly falls.
Test yourself right now. Put one hand on your chest and one hand on your belly. Take a breath. Which hand moves first?
If it’s your chest — you’re a chest breather. Your scalenes and traps are working overtime.
Breathe through your nose, not your mouth. Nasal breathing filters the air, warms it, humidifies it, and produces nitric oxide, which dilates blood vessels and improves oxygen delivery. Mouth breathing bypasses all of this and tends to be shallower and faster, which keeps your nervous system in a slightly more activated state.
Slow it down. A breathing rate of around 5–6 breaths per minute is associated with maximum Heart Rate Variability — a measure of how well your nervous system can regulate itself. Most people breathe 12–20 times per minute. Slowing down your breathing is one of the most direct inputs you can give your nervous system.
Try this: inhale for 5.5 seconds, exhale for 5.5 seconds. That’s roughly 5.5 breaths per minute. Do this for two minutes. Notice what happens in your neck and shoulders.
The double inhale for acute stress. If you’re acutely stressed or your tension is high, try a physiological sigh: a double inhale through the nose (one big breath and then a small sniff to fully expand the lungs) followed by a long, slow exhale through the mouth. Stanford research published in 2023 found this to be the most effective single breathing technique for rapidly shifting your nervous system state. It deflates the small air sacs in the lungs that collapse under stress and signals safety to your brain within seconds.
Why this matters long-term
Correcting your breathing pattern is one of the most underrated interventions for chronic neck tension. Not because breathing is magic, but because the pattern has real mechanical consequences.
Chronically overworked scalenes compress nerves. Chronically activated upper traps pull on your cervical spine. Shallow chest breathing keeps your sympathetic nervous system running. And all of it reinforces the tension pattern that brings you back to the chiropractor, the massage therapist, the physiotherapist — over and over.
You can’t stretch your way out of a breathing problem. You can’t adjust your way out of it either, long term. You have to address the pattern.
Start with five minutes of belly breathing today. Nose in, belly first, slow. That’s it.
