The research here is honest in a way that is useful. A 2017 systematic review of 31 papers found that pain changes breathing (faster, deeper, more flow) more reliably than breathing changes pain, and that paced slow breathing reduced pain in some studies with no clear mechanism. An elegant small experiment explains part of the "some": sixteen people did slow breathing in two ways at the same rate and depth, once concentrating hard on a feedback task and once relaxing. Only the relaxed version raised pain thresholds and lowered sympathetic arousal. The breathing was identical; the attitude was the variable.
Two newer studies sharpen the picture. Pooling five randomized trials in 245 pain-free volunteers, mindfulness meditation reduced evoked pain more than a "sham" meditation that was really just slow breathing, though slower breathing partly explained the relief in both. And in a pilot trial in the X-ray waiting room of a walk-in orthopedic clinic, four minutes of cyclic sighing, played asynchronously, lowered pain intensity and unpleasantness relative to an attention-matched control, with no change in anxiety or depression scores.
What to take from it: breathing helps pain modestly, when it is unforced, and attention to the breath seems to matter as much as the breath. That is the Paper Gown room in one paragraph. For persistent pain, it is a companion to care, not a replacement.

- Sample
- 31 papers (1984–2015)
- Design
- Systematic review across experimental and clinical studies.
- Found
- Pain increases respiratory flow, frequency and volume; paced slow breathing reduced pain in some studies; mechanisms unclear.
- Limits
- Heterogeneous designs; the authors call for more research.

- Sample
- 16
- Design
- Within-subject comparison of attentive versus relaxing slow breathing at matched rate and depth.
- Found
- Relaxing slow breathing raised detection and pain thresholds and lowered skin conductance; attentive slow breathing did not. Both lowered negative mood.
- Limits
- Sixteen healthy volunteers; laboratory pain.

- Sample
- 245 (pooled from 5 RCTs)
- Design
- Pooled analysis of parallel randomized trials in healthy, pain-free, meditation-naïve adults.
- Found
- Mindfulness produced greater analgesia than slow-breathing (sham-mindfulness) meditation and controls; slower respiration partially mediated relief for both.
- Limits
- Evoked experimental pain, not clinical pain; healthy volunteers.

- Sample
- Pilot RCT (n not stated in abstract)
- Design
- Single-site randomized trial in the X-ray waiting room of a walk-in orthopedic clinic; four-minute asynchronous cyclic sighing versus a time- and attention-matched control.
- Found
- Less pain unpleasantness and intensity while waiting; no difference in anxiety or depression symptoms.
- Limits
- Pilot; single site; immediate outcomes only.
