A free, low cost skill could support people working to overcome substance use. New research points to something as simple as slow, controlled breathing.

A systematic review and meta analysis published in the journal Addiction has examined the evidence. It found that controlled breathing exercises produced meaningful reductions in craving. This held true for people using alcohol, nicotine, opioids and other drugs. Dr Ariel Dart Roxburgh of Monash University led the review. Her team pooled data from 20 studies involving 1,249 participants. The findings add weight to a growing body of evidence around low cost, accessible recovery tools.

What the Research Found

Researchers combined results from 15 controlled studies. They wanted to see how breathing based interventions affected craving, withdrawal and dependence. Twelve of these studies, involving almost 700 participants, focused on craving. Controlled breathing produced a small but statistically significant reduction compared with control groups.

The effect size, measured using Hedges’ g, reached 0.30. The authors say this figure sits alongside other established approaches, such as cognitive behavioural therapy. Notably, the results held steady across different substances and settings. Community clinics and residential rehabilitation units both saw similar benefits. This suggests the effect is not limited to a single drug or population group.

Two smaller studies pointed to a larger effect on dependence severity. However, the authors urge caution given how few trials have explored this outcome so far. Evidence for withdrawal symptoms came from just four studies. Results here were inconsistent and did not reach statistical significance.

A Complement to Established Recovery Support, Not a Substitute

The authors frame controlled breathing carefully. They present it as a low cost addition to established, evidence based treatment options, not a standalone fix. Cognitive behavioural therapy and contingency management already carry a proven track record in supporting people to reduce or stop substance use. Yet both can prove time consuming and resource intensive to deliver.

Breathing exercises sit differently. They need minimal training, and people can often practise them independently once they have learned the basics. That makes them a practical skill for building resilience and self control as part of a wider recovery journey. Several trials in the review relied entirely on self directed practice, with no clinician required at every session.

The Science Behind the Breath

The theory rests on the autonomic nervous system. Emotional distress and cravings typically trigger the sympathetic nervous system, the body’s stress response. Calm, regulated states work differently. They draw on the parasympathetic nervous system instead.

Slow, paced breathing appears to shift this balance. It dampens the stress response while boosting heart rate variability, a marker of the body’s capacity to adapt and self regulate. Lower heart rate variability has previously shown links to higher relapse risk, particularly around alcohol use. Strengthening this system may therefore help people manage the urge to use.

Different Forms of Controlled Breathing

The review captured several distinct breathing techniques, each with its own approach.

Heart rate variability biofeedback, or HRVB, uses a sensor. It helps someone pace their breathing to match their heart rhythm, usually around six breaths per minute. Resonant breathing follows the same six breath per minute pace but skips the equipment entirely. Yogic breathing draws on traditional practices, including patterns of inhalation, exhalation and breath holding, such as Sudarshan Kriya Yoga. Rhemercise combines slow breathing with extra behaviours, including smiling, yawning and positive self talk. Mimicking smoking involves timed deep breaths that replicate the physical act of smoking, minus the cigarette. Three part breathing focuses on expanding different areas of the chest and abdomen in turn.

Interestingly, HRVB and simpler, unassisted techniques produced similar reductions in craving. Expensive equipment, it seems, is not essential for people to benefit.

Accessible Tools for a Global Challenge

Alcohol and drug use contribute to more than 100 million years of life lost to illness and disability each year. Alcohol alone costs economies an estimated 2.6 per cent of gross domestic product. Against this backdrop, low cost prevention and recovery tools carry real public health weight.

Dr Roxburgh pointed to another figure: an estimated 78 per cent of the world’s population now owns a mobile phone. Smartphone delivered breathing programmes could therefore reach far more people than clinic based treatment alone. Several studies in the review already used wearable sensors and phone apps to guide participants remotely. This approach cuts the need for costly clinician time.

More Robust Evidence Still Needed

The findings on craving look promising, but the authors remain candid about the limits of the current evidence. Only two studies examined dependence, and just four looked at withdrawal. Conclusions in these areas remain tentative for now. Most trials were also relatively small, and few followed participants over the longer term.

The review’s authors call for larger, pre registered trials. These should use standardised outcome measures and longer follow up periods. Only then can the true value of controlled breathing within a comprehensive recovery and prevention framework become clear.

For now, the evidence points to a simple, teachable skill. It costs nothing beyond a few minutes of practice each day. And it may help strengthen the self regulation people need on the path away from substance dependence.
