The Buteyko Breathing Technique is a breathing re-education method focused on normalizing breathing patterns to improve health conditions potentially linked to chronic hyperventilation.

Last reviewed June 17, 2026 · AI-assisted, human-reviewed
The Buteyko Breathing Technique (BBT) is a method of breathing re-education developed by Ukrainian doctor Konstantin Buteyko. It focuses on reducing breathing volume and promoting nasal breathing, aiming to correct what Buteyko believed to be chronic hyperventilation, or over-breathing. The technique involves a series of exercises designed to encourage slower, shallower breathing, primarily through the nose, and to increase breath-holding time. Proponents of Buteyko suggest that chronic hyperventilation can lead to a reduction in carbon dioxide (CO2) levels in the blood, which in turn can cause smooth muscles around airways and blood vessels to constrict, and reduce oxygen delivery to tissues. By normalizing breathing patterns, BBT aims to restore CO2 levels and improve oxygen utilization within the body. It is often taught by certified practitioners who guide individuals through the exercises and monitor their progress.

Safety:Safety · Generally safe

Evidence Summary

Evidence · Grade C

Limited but promising evidence, primarily from smaller studies, suggests that Buteyko Breathing Technique may help improve symptoms and reduce medication reliance in individuals with asthma. Some studies also indicate potential benefits for other respiratory conditions. However, larger, high-quality randomized controlled trials are needed to confirm these findings and establish efficacy across a broader range of conditions.

Why It Works

BBT aims to correct chronic hyperventilation by promoting slower, shallower, nasal breathing, which may normalize carbon dioxide levels and improve oxygen delivery to tissues.

How it works in more detail

The core principle of the Buteyko Breathing Technique is that many health issues, particularly respiratory ones, are exacerbated by chronic hyperventilation (over-breathing). When a person breathes too deeply or too frequently, they exhale too much carbon dioxide (CO2). According to the Bohr effect, CO2 plays a crucial role in releasing oxygen from hemoglobin to the body's tissues. A reduction in CO2 can lead to vasoconstriction and bronchoconstriction, and reduce the efficiency of oxygen delivery to cells, even if blood oxygen saturation is high. BBT exercises are designed to gradually reduce the volume of air inhaled, encourage nasal breathing, and increase breath-holding capacity (measured by the 'Control Pause' test). This process aims to retrain the body to tolerate higher levels of CO2, thereby relaxing smooth muscles in airways and blood vessels, and improving oxygen utilization.

How to use

Always consult a qualified clinician.

Editorial guidance

Typically involves daily practice of specific breathing exercises, often for 15-30 minutes, several times a day, guided by a certified Buteyko practitioner.
Research dosage range
Protocols typically involve daily practice of specific breathing exercises, often for 15-30 minutes, multiple times a day, under the guidance of a certified practitioner. Duration of programs can range from weeks to months.
Typical onset
Improvements in symptoms may be noticed within weeks to months of consistent practice, depending on the individual and condition.
Typical forms
breathing exercises, guided practice
Quality markers
Seek instruction from a certified Buteyko practitioner. Ensure the practitioner has recognized training and experience.
Avoid if
  • severe cardiovascular disease (without medical supervision)
  • acute asthma attack (use rescue inhaler first)
Pregnancy / lactation
Generally considered safe during pregnancy and lactation, but it is advisable to consult a healthcare provider before starting any new breathing exercises.

Traditional use

Developed in the 1950s by Dr. Konstantin Buteyko, the technique is relatively modern and not rooted in ancient traditional medicine systems.

Safety

Safety warnings

Buteyko Breathing Technique is generally considered safe when practiced correctly. Individuals with underlying health conditions, especially cardiovascular or severe respiratory issues, should consult their healthcare provider before starting. It should not be used as a replacement for prescribed medications or medical treatment.

Avoid if

  • severe cardiovascular disease (without medical supervision)
  • acute asthma attack (use rescue inhaler first)

Reported side effects

  • lightheadedness (initially)
  • dizziness (initially)
  • shortness of breath (if overdone)

Pregnancy & lactation

Generally considered safe during pregnancy and lactation, but it is advisable to consult a healthcare provider before starting any new breathing exercises.
