Slow breathing cut chronic pain by up to 37% in the strongest trials

Chronic non-cancer pain, conditions like persistent neck pain, low back pain, fibromyalgia and tension-type headache, is often managed with opioids, and there is a strong push in modern pain medicine to reduce reliance on them. That makes credible non-drug options valuable, and breathing therapy is one of the simplest candidates: cheap, low-risk and self-administered. This review asked whether breathing therapy actually reduces pain and improves health-related quality of life, physical functioning and sleep in adults with these conditions. The answer bears on whether a technique this accessible deserves a formal place alongside conventional pain management.

The authors searched MEDLINE, CINAHL, EMBASE, the Cochrane Library, PEDro and PsycINFO from inception to October 2024 for randomised clinical trials in which breathing therapy was the sole or central component of the intervention, in adults with complex chronic non-cancer pain. From 2,369 abstracts screened, ten randomised trials totalling 638 participants met the inclusion criteria. The trial populations covered chronic neck pain, chronic low back pain, fibromyalgia and tension-type headache. Each included trial was assessed for risk of bias, with quality ranging from high to critically low.

Breathing therapy significantly improved pain and/or health-related quality of life in six of the ten included trials. The most persuasive signal came from the two trials the reviewers rated at low risk of bias: both tested a similar protocol of 15 minutes of daily slow diaphragmatic breathing, and both demonstrated statistically significant, clinically relevant pain reduction of up to 37%. However, substantial heterogeneity in participants, interventions and methods prevented any pooled synthesis across studies, and with quality ranging down to critically low, the authors conclude that the evidence for breathing therapy in these conditions remains sparse.

This review positions breathing therapy as promising rather than proven for chronic pain. It fits a wider movement to build the evidence base for non-pharmacological pain management as an alternative or supplement to opioid-centred treatment, and it identifies a specific, replicable protocol, brief daily slow diaphragmatic breathing, as the version with the cleanest trial support so far. What it cannot yet do is support strong clinical recommendations: the trials are too heterogeneous to pool and too variable in quality. The authors explicitly call for high-quality trials to reinforce the evidence base before breathing therapy can claim a firm place in practice.

If you live with chronic neck pain, back pain, fibromyalgia or tension-type headache, this is a reason to take breathing practice seriously as more than a relaxation gimmick: in the best-conducted trials to date, a short daily slow-breathing routine was associated with meaningful pain reduction. It is equally a reason to hold expectations loosely, because the overall evidence is sparse, the trials vary widely in quality, and no pooled effect could be calculated. This is early-stage support for a low-burden practice: informative context for conversations about managing pain, not a substitute for them.
