Buteyko Breathing for Asthma: Clinical Trial Results
Share
The Buteyko Breathing Technique (BBT) offers a promising way to manage asthma by focusing on controlled breathing to reduce symptoms and medication use. Clinical trials show:
- Medication use reduction: Up to 86% less reliance on relievers and 50% lower corticosteroid use.
- Symptom improvement: Better asthma control rates (e.g., from 40% to 79% in some cases).
- Breathing efficiency: Techniques like nasal breathing improve COโ levels and may ease airway constriction.
However, BBT has shown limited effects on lung function tests like spirometry. While it's not a replacement for conventional treatments, it can be a useful addition to asthma management plans. Always consult a healthcare professional before starting. For Australians, certified practitioners through the Buteyko Institute of Breathing & Health (BIBH) ensure proper guidance. Tools like nasal strips can also support practice.

Clinical Trials on Buteyko Breathing: Study Overview
Clinical trials, ranging from smaller studies to comprehensive reviews, have investigated how Buteyko breathing might help manage asthma. These studies used a variety of research methods, and the following sections outline their designs and key findings from Australia and around the world.
Study Design and Methods
Building on earlier promising results, several randomised controlled trials (RCTs) have evaluated the effects of Buteyko breathing. One notable double-blind RCT by Slader et al. included 57 participants aged 15 to 80 with stable but poorly controlled asthma. The trial compared a nasal breathing technique to a control intervention over 30 weeks. Participants were selected based on their use of reliever medications at least four times a week and their maintenance on inhaled corticosteroids (minimum 200 ฮผg per day) for at least three months. Exclusions applied to current smokers, those with unstable asthma, and individuals previously trained in Buteyko.
In this study, participants were split into two groups. Group A practised breathing techniques designed to reduce tidal volume and encourage nasal breathing, while Group B performed upper-body exercises as a control. Both groups followed their assigned routines twice daily for the duration of the trial.
Other trials have also explored this method. A German study involving 60 adults compared Buteyko breathing to standard therapy over three months, while an Indian trial with 40 participants examined the combination of Buteyko breathing and medication versus medication alone.
Systematic reviews have further assessed these trials, with follow-up periods ranging from one week to 54 months. These reviews evaluated outcomes such as spirometry results, respiratory resistance, provocation tests, quality of life, medication use, and asthma symptom severity. However, designing effective control interventions remains a challenge in complementary medicine research.
Australian and Global Research Findings
Both Australian and international studies have contributed to understanding the potential benefits of Buteyko breathing. Australian research, in particular, has been instrumental in shaping global perspectives. For example, the Slader et al. study conducted across multiple Australian centres reported significant improvements in both the Buteyko and control groups. Reliever medication use dropped by 86%, and inhaled corticosteroid doses were reduced by 50%. However, no major differences were observed between the groups practising Buteyko breathing and those performing upper-body exercises at weeks 12 or 28. This suggests that the benefits might come from shared elements of the interventions rather than the Buteyko technique itself.
Globally, studies have shown mixed but valuable results. Some international research has noted improvements in lung function, including enhanced FEVโ in Buteyko groups. A Canadian RCT involving adults with asthma on conventional therapy found that participants practising Buteyko breathing significantly reduced their inhaled corticosteroid use compared to controls. Additionally, one study reported a 70% reduction in nasal symptoms among participants using Buteyko techniques.
Another international trial highlighted improvements in the body's acidโalkali balance and lung ventilation. Researchers noted that:
Professor Buteyko's method reduced attack frequency, lowered medication doses, and improved acidโalkali balance and lung ventilation.
These trials have been conducted across various countries, including Australia, Canada, Germany, India, and the United Kingdom. Systematic reviews have also identified meaningful physiological changes. For instance, one review reported a significant shift in end-tidal COโ levels, with a weighted mean difference of 1.65 mmHg across five trials involving 313 participants.
While global research acknowledges the potential benefits of breathing exercises like Buteyko, the overall evidence remains varied. Reviews suggest that breathing-focused behavioural programmes, including Buteyko, may ease asthma symptoms, improve quality of life, and reduce the need for bronchodilators. However, they seem to have limited impact on lung function.
These findings support the idea of incorporating Buteyko breathing into broader asthma management plans, offering a complementary approach for Australian patients.
Clinical Results: What the Evidence Shows
Research on Buteyko breathing offers a mix of results, but thereโs growing interest in its potential for managing asthma. While studies show positive outcomes in some areas, the evidence varies depending on the specific measures and groups studied.
Key Trial Results
Several trials report benefits like a better quality of life and reduced reliance on asthma medications. For instance, one randomised controlled trial found that participants practising Buteyko breathing had a notable improvement in quality of life (p = 0.043) compared to a placebo group. Additionally, their use of inhaled bronchodilators dropped significantly (p = 0.008). Another study revealed that asthma control rates increased from 40% to 79% among those using Buteyko techniques, compared to a rise from 44% to 72% in the control group.
The "control pause test", a core aspect of Buteyko breathing, also showed measurable progress. Participantsโ average control pause time increased from 12.70 seconds to 30.94 seconds - a 147.45% improvement (p = 0.0001). Medication use dropped by roughly 20% in some studies, and one trial noted a significant reduction in inhaled corticosteroid use among Buteyko participants compared to controls (p = 0.02). In school-age children, Buteyko breathing led to a marked improvement in peak expiratory flow rate (p = 0.0001) and a reduction in heart rate (p = 0.003) over four weeks.
However, standard lung function tests, such as spirometry, havenโt shown significant changes with Buteyko breathing. These findings highlight areas of success but also underline the need for further exploration of its full potential.
Study Limitations and Evidence Gaps
Although the results are encouraging, there are several challenges and gaps in the research. Many studies have small sample sizes - often fewer than 60 participants - which limits the reliability and broader applicability of the findings. Methodological issues also persist. For example, a 2015 review by the Australian Government's Department of Health assessed 17 alternative therapies and found no strong evidence supporting the effectiveness of the Buteyko method.
Blinding is another issue. Creating a true placebo for breathing techniques is tricky, meaning both participants and researchers are aware of the intervention, which could influence subjective outcomes like quality of life. Additionally, inconsistent study designs make it hard to compare results across trials.
Selection bias might also play a role. People who volunteer for breathing studies may differ in motivation or other factors from the general asthma population. Finally, thereโs limited data on the long-term sustainability of the benefits reported. These factors contribute to scepticism within the medical community, with some critics labelling claims about Buteyko breathing as "exaggerated and unsubstantiated".
Buteyko vs Conventional Asthma Treatment
Comparing Buteyko breathing with standard asthma treatments reveals distinct strengths and limitations for each approach.
| Aspect | Buteyko Breathing | Conventional Asthma Treatment |
|---|---|---|
| Medication Use | May reduce reliance on relievers and preventers by ~20% | Primarily depends on bronchodilators and anti-inflammatory drugs |
| Lung Function | No significant impact on spirometry results | Proven improvements in lung function via spirometry |
| Quality of Life | Statistically significant improvements (p = 0.043) | Provides effective symptom management to enhance daily life |
| Asthma Control | Control rates improved from 40% to 79% | Consistently achieves symptom control through established protocols |
These comparisons suggest that Buteyko breathing works best as a complementary method rather than a substitute for conventional treatments. For those looking to reduce their dependence on medications, integrating Buteyko breathing under medical guidance could be a valuable option. However, itโs essential to approach this technique with realistic expectations and proper monitoring.

How Buteyko Breathing Works
Buteyko breathing works by adjusting how deeply and frequently you breathe, aiming to counteract hypocapnia - a condition where reduced carbon dioxide (COโ) levels can cause airway constriction. People with asthma often breathe more heavily and quickly than those without the condition. By consciously slowing and lightening the breath, this technique helps reduce the total volume of air taken in per minute (minute ventilation), encouraging a return to more natural breathing patterns.
The method focuses on regulating COโ levels in the body. According to the Buteyko approach, chronic overbreathing lowers COโ levels, triggering the body's defensive responses, which can worsen asthma symptoms. By slowing down the breathing rate and reducing its depth, COโ levels can be stabilised. For instance, a study found that participants practising Buteyko breathing reduced their respiratory rate from 32.5 to 23.5 breaths per minute, while their average oxygen saturation improved from 92.5% to 98.5%.
Nasal Breathing and Asthma Management
A key part of this technique is nasal breathing, which enhances the benefits of controlled ventilation. Breathing through the nose warms, filters, and humidifies the air before it enters the lungs, offering a natural layer of protection for sensitive airways. This is particularly beneficial for individuals with asthma, as mouth breathing allows cold, dry, and unfiltered air to directly reach the lungs, potentially irritating inflamed airways.
Nasal breathing also promotes the production of nitric oxide, a naturally occurring compound that acts as a bronchodilator, helping to relax airway muscles and reduce constriction. Additionally, the practice encourages diaphragmatic breathing - using the diaphragm rather than chest and shoulder muscles - which improves oxygen exchange while requiring less effort. To support nasal breathing, tools like BWLL Nasal Strips can assist in keeping nasal passages open, making it easier to maintain this technique during both practice sessions and everyday life.
Sleep Quality and Medication Reduction
Beyond improving breathing, some individuals have reported better sleep quality while practising Buteyko breathing, possibly due to fewer asthma symptoms disrupting their rest at night. While these improvements in sleep are anecdotal, they highlight the broader benefits of better breathing habits.
Clinical trials suggest that Buteyko breathing can also help reduce dependence on asthma medications. However, any changes to medications should always be made under the guidance of a healthcare professional. These reductions in medication use are likely linked to improved baseline respiratory function as patients adopt healthier breathing patterns and stabilise their COโ levels.
Using Buteyko Breathing in Australia
In Australia, more people are exploring Buteyko breathing as a way to complement traditional asthma treatments. With asthma being a common issue in Australian general practice, the interest in this method highlights the importance of finding qualified practitioners to ensure safe and effective learning.
Finding Qualified Practitioners
The Buteyko Institute of Breathing & Health (BIBH) is the main professional body for certified Buteyko practitioners in Australia. Practitioners registered with BIBH undergo ongoing training and professional development, maintaining high standards in teaching the technique.
When choosing a practitioner, ensure they are BIBH-registered. This certification guarantees theyโve completed the necessary training. The traditional Buteyko Institute Method is typically taught through a structured course of five 90-minute sessions over ten days. Many practitioners also offer free introductory seminars to showcase the benefits of the technique.
Prominent instructors in Australia include Paul O'Connell, Brian Firth, and Glenn White, all of whom bring extensive experience in teaching this method. You can choose between online or in-person courses, depending on your preference.
Tools to Support Nasal Breathing
To complement professional guidance, certain tools can help support your Buteyko breathing practice. Since nasal breathing is central to the technique, keeping your nasal passages clear is essential. Products like BWLL Nasal Strips can be a helpful addition.
These strips are drug-free, hypoallergenic, and designed to keep nasal passages open, making them useful during practice sessions and daily activities. Theyโre also safe for use during pregnancy and suitable for sensitive skin. Priced from $36.00 for a pack of 30, these strips offer an affordable way to support your breathing exercises, especially during sleep.
Fitting with Australian Asthma Guidelines
Buteyko breathing doesnโt just complement personal asthma management - it also aligns with Australian asthma care standards. The Global Initiative for Asthma (GINA) states that "breathing exercises may be a useful supplement to medications". Similarly, Australian asthma guidelines recommend breathing exercise programmes, including those taught by physiotherapists, as a way to improve quality of life and reduce symptoms.
Australian healthcare professionals increasingly recognise the value of breathing training programs like Buteyko, especially for those whose asthma symptoms persist despite proper medication. Studies show that functional breathing disorders play a significant role in asthma for many patients, with about one-fifth of people attending difficult asthma clinics experiencing breathing dysfunctions. Additionally, research indicates that a notable percentage of asthma patients in general practice show signs of hyperventilation or dysfunctional breathing.
Before starting Buteyko breathing, consult your GP or respiratory specialist, particularly if you have chronic breathing conditions. They can help determine if this method suits your needs and how it can work alongside your current treatment plan. Remember, Buteyko breathing requires consistent practice and is best approached as a long-term commitment rather than a quick solution. It involves both learning and incorporating the techniques into daily life, making it a comprehensive approach to asthma management.
Conclusion
Clinical trials suggest that the Buteyko Breathing Technique (BBT) can significantly reduce the need for asthma medications. Some studies report up to an 86% decrease in reliance on reliever medications, a 50% reduction in inhaled corticosteroid use, and, in one Brisbane-based trial, an impressive 96% drop in reliever use and a 49% reduction in preventer medications after just 12 weeks.
Beyond cutting down on medication, BBT has been shown to improve overall asthma control. Control rates have risen from 40% to 75% in some cases, and participants have seen a 70% decrease in nasal symptoms like snoring, loss of smell, congestion, and difficulty breathing through the nose.
That said, there are limitations to the evidence. While BBT consistently helps with symptom control and medication reduction, its impact on lung function and airway hyperresponsiveness has been inconsistent. Some research suggests that similar benefits may come from other structured breathing exercises or upper body routines, hinting that the act of regular breathing practice itself could be the key rather than the specific Buteyko method.
For Australians managing asthma, BBT offers a complementary approach that aligns with national asthma guidelines, which recommend breathing exercises alongside medication. Since nasal breathing is a core part of the technique, tools like BWLL Nasal Strips can make a real difference. At $36.00 for 30 strips, they provide an affordable way to reduce nasal resistance and support the nasal breathing essential to BBT.
While BBT is not a substitute for standard asthma treatments, evidence shows it can be a valuable addition. Success depends on proper training from qualified practitioners and a commitment to regular practice. When done correctly, BBT can reduce medication dependence and improve quality of life, making it a worthwhile complement to conventional care.
FAQs
How effective is the Buteyko Breathing Technique compared to traditional asthma treatments over the long term?
Clinical trials indicate that the Buteyko Breathing Technique may assist in managing asthma by easing symptoms, reducing medication use, and improving day-to-day well-being. Some research highlights that these benefits can persist for several months. However, this technique is typically viewed as a supplementary method rather than a substitute for standard medical treatments.
While these findings are encouraging, thereโs still a lack of extensive long-term studies directly comparing Buteyko to conventional asthma therapies. Always consult your healthcare provider before adjusting your asthma management plan.
What are the steps to practise the Buteyko Breathing Technique, and how can beginners get started?
To practise the Buteyko Breathing Technique, find a comfortable seat and ensure your posture is upright but relaxed. Start by gently inhaling through your nose and then exhaling naturally. After exhaling, pinch your nose to hold your breath until you feel the natural urge to breathe again. Once you release your nose, return to calm, steady nasal breathing. Repeat this cycle a few times, keeping your body relaxed throughout.
A core principle of this technique is to always breathe through your nose, not just during practice but in daily life as well. This habit supports better oxygen balance and encourages healthier breathing patterns. Begin with brief sessions and gradually extend them as you grow more at ease with the method.
Are there any risks or side effects when using the Buteyko Breathing Technique for managing asthma?
The Buteyko Breathing Technique is widely regarded as a safe practice, with most people reporting minimal or no side effects. That said, some individuals might experience mild symptoms at first, such as more mucus, headaches, or fatigue, as their body adapts to the technique.
There havenโt been any reports of serious negative effects, which makes it a low-risk option for managing asthma. However, itโs always wise to check in with your healthcare provider before trying any new breathing exercises, particularly if you have severe asthma or other health concerns.
