Breathing

Hum a slow, sinking sigh on each exhale — a few unhurried breaths to settle, body and mind.

Why this works

Why might this feel calming? A few threads of research point the same direction. Slow breathing at around six breaths a minute sits near what scientists call your "resonance frequency," a pace that's associated with greater heart-rate variability through a vagally-mediated reflex (respiratory sinus arrhythmia) that many people experience as relaxing. Your heart naturally slows a little on the exhale, so a longer, unhurried out-breath is part of why extended-exhale practices feel settling. Humming and "OM"-style toning add gentle vibration around the throat and ears, and some researchers suggest this may contribute to the calm, though that specific pathway is still a working hypothesis rather than a proven one. Much of the soothing effect likely just comes from the slow, paced breathing the sound encourages. The research here is early and mixed, so think of this as a relaxation and warm-up practice, not a treatment.

This is a relaxation and breathing practice for general wellness, not a medical treatment, and it isn't intended to diagnose, treat, cure, or prevent any condition. If you feel dizzy or unwell, stop and breathe normally; never do breathing exercises in water or while driving.

Frequently asked questions

What is this breathing exercise?
It's a short, guided slow-breathing practice. You breathe in for a few seconds, then hum a soft, descending sigh as you breathe out, with a brief settle in between. A few unhurried rounds help calm your nerves and gently warm up your voice before you sing.
Do I need an account or to install anything?
No. The breathing exercise is completely free, needs no signup, and runs right in your web browser. Just allow microphone access and begin.
Why does it ask for my microphone?
On the exhale you hum a gentle note, and the on-screen comet follows your pitch so you can let it sink as you relax. Audio is processed in your browser in real time — your raw microphone audio is never uploaded.
Is slow breathing actually good for me?
Research links slow breathing of around six breaths per minute, and gentle humming on the exhale, to relaxation and a calmer nervous system. This is a general wellness practice, not medical advice; if you feel light-headed, stop and breathe normally.
