Claim reviewed: Breathwork may help reduce self-reported stress.
What do we know?
In a meta-analysis of 12 randomised trials, breathwork was linked to a small-to-medium reduction in self-reported stress compared with non-breathwork controls (g = −0.35). Biofeedback-based breathing training also showed a large reduction in stress and anxiety.
What don't we know?
Most studies carry moderate risk of bias and the techniques vary widely; which technique works is unclear. Techniques with fast breathing or breath holding are outside this product's scope.

A meta-analysis of randomised trials comparing breathwork with non-breathwork controls: a small-to-medium reduction in self-reported stress (12 trials, 785 adults), with similar effects on secondary mental health measures. Most studies had moderate risk of bias; the authors urge caution so that hype and evidence are not confused.
Self-reported stress: g = −0.35 (95% CI −0.55 to −0.14)
One author declared a link with a foundation that teaches breathing techniques.

A meta-analysis of 24 studies (484 participants) on heart rate variability biofeedback training: a large reduction in self-reported stress and anxiety (g = 0.83 against controls). The authors call for better-controlled studies.
Between-groups g = 0.83
Biofeedback paces breathing to heart rhythm measured by a device; it is not the same as pacing with sound alone.
