Effectiveness of mindful breathing exercises on symptom reduction and quality of life in individuals with major depressive disorder: A systematic review.
Saad Bin Muaythir, Nombeko Mshunqane, Enos Ramano and 2 others
Two small trials found that mindful breathing reduced anxiety and improved sleep in people with depression, but neither measured quality of life, one combined breathing with talk therapy, and both lacked blinding.
Too thin to change practice.
Key findings
1In 89 hospitalised patients with MDD, a programme that combined cognitive behavioural therapy with 10 minutes of breathing relaxation per session (3 sessions/week for 4 weeks) produced statistically significant improvements in sleep quality and heart-rate variability, sustained at follow-up. Because both components were delivered together, the contribution of breathing alone cannot be separated from that of the therapy.
2In 30 patients with depression scheduled for electroconvulsive therapy, a 10-minute session of slow breathing at six breaths per minute, done immediately before the procedure, produced a statistically significant reduction in anxiety scores (p < 0.001) compared with baseline.
3Neither included study provided a comprehensive assessment of quality-of-life outcomes such as psychological well-being, social functioning, daily role functioning, or overall life satisfaction, which was a stated aim of the review.

What it does not show
Only two trials met the inclusion criteria, so the review cannot support broad generalisations about mindful breathing for MDD. One trial combined breathing with cognitive behavioural therapy, so the effect of breathing alone cannot be isolated. Neither trial blinded participants or outcome assessors, and both relied on self-reported measures (sleep quality, anxiety), raising the possibility that expectancy effects inflated the results. Neither trial measured the quality-of-life outcomes (social functioning, daily role, life satisfaction) that the review's own research question asked about. Follow-up was short in both trials, so whether the benefits last beyond a few weeks is unknown. Participants came from two very specific settings (hospitalised psychiatric patients in Taiwan and patients scheduled for electroconvulsive therapy in Iran), limiting applicability to outpatient, community, or primary-care populations. No meta-analysis was possible because the interventions, populations, and outcome measures were too heterogeneous to pool.
Declared interests
The authors state that the research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors. No other conflicts of interest are declared.
The easy way to misread this
Do not read this review as evidence that mindful breathing alone treats major depressive disorder. One of the two trials bundled breathing with cognitive behavioural therapy, so the breathing component's independent effect is unknown; neither trial measured the quality-of-life outcomes the review set out to assess; both were unblinded with self-reported endpoints; and follow-up was short. The review's own stated aim included quality of life, yet no included study actually measured it, so the positive headline rests on sleep and anxiety scores from two small, unblinded trials in narrow clinical settings.
