    Coherent Breathing

    Five-second inhales and five-second exhales — a 5.5 breaths-per-minute rhythm shown to maximise heart rate variability and reduce anxiety.

    Coherent breathing, also called resonant breathing or 5-5 breathing, is the cleanest, simplest version of paced breathing. You inhale for five seconds and exhale for five seconds. That cadence — roughly six breaths per minute — lands inside what cardiologists call the resonance frequency of the cardiovascular system, where heart rate variability peaks.

    Why it works

    At ~5.5 breaths per minute the heart, lungs, and baroreflex enter coherence: their oscillations sync up. Multiple randomised trials show 10 minutes a day reduces symptoms of generalised anxiety and depression, improves HRV, and lowers resting blood pressure. It is the breath cadence Stephen Elliott popularised after decades of research at HeartMath and the Coherence Project.

    How to do coherent breathing

    1. Sit comfortably or lie down. Loosen your jaw and shoulders.
    2. Inhale through the nose for a smooth count of 5.
    3. Exhale through the nose (or mouth) for the same smooth count of 5.
    4. Keep the breath low and quiet — the belly expands, the chest stays soft.
    5. Continue for 5–20 minutes. There are no holds.

    When to use it

    • As a daily morning or evening meditation practice.
    • When you want a calmer baseline rather than an emergency reset.
    • Alongside journaling or cold exposure for compounded effects.

    Frequently asked questions

    Is coherent breathing the same as resonant breathing?

    Effectively yes. 'Resonance' refers to the cardiovascular sweet spot of 4.5–6.5 breaths per minute. A 5-5 cadence sits right in the middle and is the easiest pace to learn.

    Can I do it for longer than 20 minutes?

    Yes. There is no upper limit. Many practitioners run a continuous coherent breath under their working day as a base layer.
