This is a free online coherence breathing timer — no sign-up, nothing to install, all of it running in your browser — where you press Begin and follow an animated orb through six rounds of five seconds in and five seconds out, with each phase named and counted down on screen, Pause and Reset if you need them, and nothing saved when you close the tab. Coherence breathing — sometimes called resonance or resonant-frequency breathing — is one of the simplest techniques there is: a smooth inhale, a smooth exhale, no holds. That works out to about six breaths per minute, the rate at which the heart, lungs, and nervous system fall into sync.
How to Practice
- 1
Inhale. Breathe in smoothly through your nose for 5 seconds, filling your belly.
- 2
Exhale. Breathe out smoothly for 5 seconds with no pause, then continue the even rhythm.
Why Coherence Breathing Works
Around six breaths per minute, your heart rate and breathing rhythm synchronize in a state researchers call "cardiac coherence." In this state, heart rate variability — the natural beat-to-beat variation in your pulse — reaches its peak. Higher HRV is associated with better stress resilience, emotional balance, and recovery.
Because the inhale and exhale are equal and continuous, coherence breathing does not push you toward alertness or drowsiness; it brings you to the center. That makes it an excellent everyday baseline practice, a gentle way to regulate your nervous system without any of the breath-holding that other techniques involve.
When to Use It
Coherence breathing is ideal as a daily practice — five to ten minutes once or twice a day builds a calmer baseline over time. It is also a great entry point for anyone new to breathwork, since the rhythm is so easy to maintain and there are no holds to manage.
Use it to steady yourself during a stressful afternoon, to focus before deep work, or to transition between activities. Because it is balancing rather than sedating, it fits comfortably at almost any time of day.
Tips for Best Results
Aim for smooth, continuous breathing with no pause between the inhale and exhale — the breath should flow like a wave. Breathe through your nose and into your belly, keeping each phase soft and unforced.
Five seconds in and five out suits most people, but the ideal "resonant" rate varies slightly from person to person, usually between about 4.5 and 6.5 seconds per phase. Feel free to experiment to find the pace that feels most natural. Longer sessions yield more benefit, so build toward ten minutes as it becomes comfortable.
Link parameters
The round count travels in the address bar, so a link can open the timer at the length you want.
| Parameter | Values | Example |
|---|---|---|
| rounds | 1 to 20 rounds | /coherence-breathing/?rounds=12 |
/coherence-breathing/?rounds=12 runs twelve rounds — two minutes at five seconds in and five out.
/coherence-breathing/?rounds=20 is the longest the timer accepts, a little over three minutes.
Frequently Asked Questions
Is there a free online coherence breathing timer with no sign-up? +
Yes. This page is one: free to use, no account to create, and nothing to install, since it runs in your browser on a phone, tablet or computer. Press Begin and follow the orb through six rounds of five seconds in and five seconds out, with each phase named and counted down. Nothing is saved and nothing is sent anywhere.
What is coherence breathing? +
Coherence breathing is a technique of breathing at about six breaths per minute — typically a 5-second inhale and a 5-second exhale — to bring the heart and nervous system into a balanced, "coherent" state.
How does coherence breathing improve HRV? +
At roughly six breaths per minute, heart rate naturally rises on the inhale and falls on the exhale in a large, synchronized wave. This maximizes heart rate variability, a marker linked to stress resilience and recovery.
How long should I practice coherence breathing? +
Five to ten minutes once or twice a day is a common recommendation. Even a few minutes is calming, and consistent daily practice builds a steadier baseline over time.
Is 5-5 the best breathing rate for everyone? +
Five seconds in and out works well for most people, but the ideal resonant rate varies — usually between about 4.5 and 6.5 seconds per phase. Experiment to find the pace that feels most natural and effortless.
Is coherence breathing good for beginners? +
Very much so. With no breath holds and a simple, even rhythm, it is one of the easiest techniques to learn, which makes it a great starting point for anyone new to breathwork.
