The Science Behind Breathing Retraining and Asthma.
Breathing retraining has been studied as a complementary approach in asthma management for several decades. While it does not replace medical treatment, clinical research suggests that structured breathing interventions improve asthma control, reduce symptom burden and enhance quality of life in some individuals.
Most studies focus on methods such as Buteyko and functional breathing retraining. Evidence shows stronger effects on symptom perception and breathing regulation than on standard spirometry measures like FEV₁.
Asthma is complex, involving airway inflammation and nervous system responses. Breathing retraining primarily targets breathing patterns, ventilatory efficiency and autonomic regulation factors that may influence symptoms even when lung function remains stable.
Below you’ll find selected peer-reviewed studies relevant to this field.
Effect of Two Breathing Exercises (Buteyko and Pranayama) in Asthma (Thorax, 2003)
Population: Adults with asthma on inhaled corticosteroids
Key findings:
-
Buteyko breathing reduced symptom scores more than control and pranayama groups
-
Participants practicing Buteyko reduced bronchodilator use
-
No significant improvement in FEV₁ (lung function) was found
-
This suggests that breathing retraining may reduce symptoms and medication reliance without changing measured lung function.
Population: Adults with mild to moderate asthma
Key findings:
• Improved self-reported quality of life
• Reduced use of reliever medications
These effects were noted after 4 weeks of practice, suggesting benefit even with remote instruction.

Effect of the Buteyko Breathing Technique on Asthma (European Journal of Medical Research, 2023)
Population: Adults with asthma
Key findings:
• Improved asthma control ↓
• Reduced medication use
• Increased voluntary breath-hold durations (a proxy for CO₂ handling)
• Some functional respiratory improvements at rest
The study concluded that Buteyko therapy may be a valuable supportive tool in asthma care when paired with standard treatment.
Population: Children 7–12 years with asthma
Key findings:
• Significant improvements in asthma control scores (statistically significant)
• Quality of life increased significantly in group combining Buteyko with standard care
This suggests potential benefit of retraining techniques in pediatric asthma management.
