What is Coherent Breathing?
Coherent Breathing describes both a breathing method and a means of internal state management: breathing at the nominal rate of 5 breaths per minute with equal periods of inhalation and exhalation and conscious relaxation of anatomical zones known as “The Six Bridges.” Unlike many traditional breathing practices that emphasize depth or retention, coherent breathing focuses on rhythm and relaxation to create wave action in the circulatory system. The goal is to consciously adjust your breathing cycle to about five breaths per minute instead of the normal higher rate of breaths per minute, with each full cycle (inhalation and exhalation) lasting approximately 12 seconds. This specific pace is designed to synchronize respiratory, cardiovascular, and autonomic nervous system rhythms at what is known as the body’s resonant frequency.
The method involves two core components: the breathing pattern itself and the deliberate relaxation of six anatomical zones that possess dual conscious-subconscious control—the face, tongue and throat, hands, diaphragm and intercostals, pelvic floor, and feet. According to Stephen Elliott, when breathing is coherent, it influences the heart rate variability (HRV) cycle, which tends to synchronize with the breath. This synchronization creates what Elliott termed the “Valsalva Wave,” a measurable oscillation in arterial pressure that enhances circulation throughout the body and brain.
Origins & Lineage
The term “Coherent Breathing” was coined by Stephen Elliott, circa 2004, upon launching COHERENCE LLC, with the trademark filed in November of 2005. Elliott, an engineer and scientist with a background in advanced electronics research and a deep interest in Eastern practices including Chinese medicine and Daoist philosophy, developed the method through biofeedback research in the early 2000s. Coherent Breathing is a form of resonant breathing introduced by Stephen Elliott of COHERENCE LLC in 2005, coincident with the publication of The New Science Of Breath.
Aided by Elliott, clinician and colleague Dee Edmonson, RN, BCIAC-EEG began employing prototype audio recordings in the 2002 time frame, in combination with multiple simultaneous forms of biofeedback including heart rate variability, electroencephalography, electrodermal response, and hand temperature. Their findings were documented in Elliott’s books The New Science Of Breath (2005) and Coherent Breathing – The Definitive Method (2008), both co-authored with Dolores Edmonson.
Elliott and Edmonson presented their clinical experience and research findings at consecutive meetings of The International Society For NeuroFeedback And Research (ISNR) and The Association For Applied Psychology and Biofeedback (AAPB) in the 2004-2008 timeframe. Drs. Brown and Patricia Gerbarg (Columbia and New York Medical College, respectively) later integrated it into their Breath-Body-Mind program where it has been used extensively in their training programs and disaster relief initiatives, including work with the Veterans Administration.
While Elliott formalized coherent breathing as a specific protocol in the 21st century, coherent breathing came as a result of years of studying the ancient breathing practices of indigenous people around the world, from yoga and qi gong to African, Hawaiian, and Native American traditions. The practice builds on millennia of breath-focused contemplative traditions, particularly the yogic concept of pranayama, though it distinguishes itself through its precise frequency specification and scientific validation.
How It’s Practiced
Coherent breathing practice centers on breathing at approximately 5 breaths per minute—significantly slower than the typical resting rate of 12-20 breaths per minute. Each inhalation lasts roughly 6 seconds, followed by a 6-second exhalation, creating a smooth, continuous rhythm without pauses or breath retention. The breath should be natural in depth, neither forced nor shallow, with diaphragmatic movement that is sinusoidal—accelerating smoothly, decelerating, reversing, like a pendulum.
Practitioners sit or lie comfortably and use the breath as an anchor while simultaneously releasing tension in the six anatomical “bridges.” During exhalation, particular attention is given to consciously relaxing these zones, supporting the parasympathetic “rest and digest” response. This technique should be practiced for 20 minutes per day for 21 days, with the eventual goal that the person should learn to dwell in the state of coherent breathing.
Audio recordings, apps, and visual timers are commonly used to maintain the 5-breath-per-minute pace until the rhythm becomes internalized. The practice does not require specific postures or complicated techniques, making it accessible to beginners. Unlike many breathwork modalities, coherent breathing is gentle and does not involve hyperventilation, forceful breathing, or extreme breath holds.
Coherent Breathing Today
Coherent breathing has expanded beyond its biofeedback origins into mainstream wellness, clinical psychology, trauma therapy, and integrative medicine. The method appears in yoga studios under various names including “resonant breathing,” “6:6 breathing,” and “Even Stephen” breath. Mental health professionals incorporate it into anxiety and depression treatment protocols, while medical practitioners recommend it for blood pressure regulation and cardiovascular health.
Dr. Richard Brown and Dr. Patricia Gerbarg have been instrumental in globalizing the practice, bringing coherent breathing to humanitarian relief contexts, disaster response settings, and military veteran support programs. Their Breath-Body-Mind framework combines coherent breathing with movement and meditation practices drawn from yoga and qigong traditions.
Research continues to validate the physiological benefits of breathing at resonance frequency. Resonance breathing has consistently been shown to increase HRV, mood, and adaptability. Increased parasympathetic and decreased sympathetic activity were observed after practicing 20 minutes of resonance frequency breathing every day for four weeks, and it also improved cognition and reduced perceived stress levels among young adults.
Seeekers encounter coherent breathing through meditation apps, breathwork facilitators, HRVB (heart rate variability biofeedback) practitioners, and recordings available at coherence.com and coherentbreathing.com. It is taught in somatic therapy trainings, yoga teacher certifications, and stress management workshops worldwide.
Common Misconceptions
Coherent breathing is not a spiritual practice in itself, though it can complement contemplative traditions. It is a physiologically-based protocol with measurable effects on the cardiovascular and nervous systems, distinct from mystical or energetic breath practices found in some yogic or shamanic lineages.
It is not the same as deep breathing or diaphragmatic breathing generally. The defining characteristic is the specific rate of 5 breaths per minute, not simply breathing more deeply. Unlike some other types of breathwork, coherent breathing focuses on the length of inhalation and exhalation, and not on how deeply you are taking in air.
Coherent breathing is also not synonymous with all resonant frequency breathing. RF changed between Test and Retest sessions in 66.7% of participants, and this instability could be related to the average of interbeat interval. While 5 breaths per minute is the nominal resonance frequency for most people, individual resonant frequency can vary slightly and may require biofeedback assessment for precision.
The practice is not a quick fix or a substitute for medical treatment. While research supports its benefits for stress, mood, blood pressure, and HRV, it requires consistent practice—typically 20 minutes daily for at least three weeks—to establish lasting effects.
How to Begin
The most direct entry point is Elliott’s book The New Science Of Breath: Coherent Breathing for Health, Well-being, Performance & Longevity (2005, revised 2006), which provides both theoretical foundation and practical protocols. Audio recordings specifically paced at 5 breaths per minute are available from COHERENCE LLC at coherence.com, including tracks with tones or chimes that guide the inhale-exhale rhythm.
Smartphone apps and online timers designed for coherent breathing offer accessible tools for beginners. Search for “coherent breathing” or “5 breaths per minute” timers. Many meditation apps now include resonant breathing features. Start with 5-10 minutes daily and gradually extend to the recommended 20 minutes.
For those seeking professional guidance, look for breathwork facilitators, HRVB practitioners, or therapists trained in the Breath-Body-Mind method developed by Drs. Brown and Gerbarg. The practice integrates naturally with yoga nidra, restorative yoga, meditation, and other parasympathetic-activating modalities. No special equipment is required beyond a timer or audio guide, making coherent breathing one of the most accessible evidence-based breathing practices available.
