Precise Breath
Your Clinician Has Recommended Precise Breath
Resonant frequency breathing is a specific slow breathing practice, done at the pace that produces the strongest response in your cardiovascular system. Precise Breath uses a chest strap heart rate sensor to find that pace and guide your daily practice.
Why It Works
Stress & Anxiety
A review of 24 studies found that breathing at your resonant frequency significantly reduced self-reported stress and anxiety, with a large overall effect (Goessl et al., 2017).
Blood Pressure
Controlled studies have linked resonant frequency breathing to reductions in blood pressure and improved cardiovascular reflexes (Steffen et al., 2017).
Autonomic Balance
Practicing at your resonant frequency strengthens the body's automatic regulation of heart rate and blood pressure over time (Lehrer & Gevirtz, 2014).
These findings describe published research on resonant frequency breathing as a practice. Precise Breath is a wellness tool — not a medical device. Individual results may vary.
Getting Started
Get a Chest Strap Sensor
You'll need a Bluetooth chest strap heart rate monitor. The Polar H10 (~$100) is recommended; the Garmin HRM Dual also works. Available at most sporting goods retailers or online.
Download Precise Breath
Available on Google Play (Android) and the App Store (iOS). The app is free to download. A one-time Premium unlock ($14.99) enables the HRV analysis modes your clinician recommends.
Run Your First Calibration
The Calibrate session (~14 minutes) tests 5 breathing rates to find your starting point. Tips: turn on Do Not Disturb, wet the chest strap electrodes, and sit comfortably in a quiet spot.
Practice Daily
Use Resonate mode for 15–20 minutes each day at your identified rate. Use Explore mode periodically to let the app refine your frequency over time. Consistency is key.
