    Coherent breathing

    About six calm breaths a minute

    Coherent breathing is a smooth inhale and exhale of about 5.5 seconds each. No holds, just a steady pace.

    A one-minute round fits a short break between focus sessions. This page is a practice guide, not medical advice.

    1. 01

      Choose a goal

      Sleep, calm, focus, or a one-minute reset. Or pick a technique such as box breathing, 4-7-8, or coherent breathing.

    2. 02

      Follow the rhythm

      Watch the sphere grow and shrink, or trace the box. With your eyes closed, follow the tone.

    3. 03

      Stop when you need to

      Pause anytime. Sessions, saved rhythms, and your streak stay on this device.

    A rhythm you can follow without staring

    The sphere, the box, the flower, and the wave share one clock. A tone rises as you breathe in and falls as you breathe out, so the screen can stay dim. Night mode softens the stage. Present mode clears the rest of the page. Saved rhythms and your streak stay in this browser.

    What you get

    • Glass orb The sphere swells as you inhale and settles as you exhale, with a ring that shows the current phase.
    • Box trace A light travels the square so each side is one part of the breath.
    • Eyes-closed guide A tone rises and falls with the breath, and chimes mark each change.
    • Private on this device Saved sessions and practice history stay in this browser. Nothing is sent to a server.

    Breathing techniques

    • Box breathing Inhale, hold, exhale, and hold empty for four seconds each. The even rhythm is a simple way to steady attention.
    • 4-7-8 breathing Inhale for 4, hold for 7, exhale for 8. The long exhale is widely used as a wind-down. Start with a few rounds.
    • Coherent breathing About six breaths a minute, in and out, with no holds. Many people use this pace for a calmer, steadier rhythm.
    • Physiological sigh A full inhale, a short second sip, then a long exhale. A few rounds are often enough to take the edge off.
    • Extended exhale Breathing out for twice as long as you breathe in. A simple pattern for slowing down.
    • Triangle breathing Inhale, hold, and exhale for the same length. Three sides, and no empty hold — a gentle first pattern.
    • Equal breathing Matching the length of each inhale and exhale. A steady foundation before longer holds.
    • Energizing breath A shorter inhale and exhale, about two seconds each. A few rounds are enough for a gentle wake-up. Stop if you feel light-headed.

    Breathe safely

    These patterns are for relaxation, not medical treatment. Long holds and fast breathing can make you light-headed. Sit or lie down. Do not practice while driving or in water. Stop if you feel dizzy or unwell. Skip long holds if you are pregnant or have a heart or lung condition.
