Notes on working calmly
Stress at work · 7 min
Stress at work: a five-minute reset you can do at your desk
A short, practical routine to come down after a tense meeting or a hard morning: breathing, a real micro-break and a calmer desk. What research supports, and its limits.
Explainer · 6 min
Brown noise, pink noise, rain: what's the difference for focus?
White, pink and brown noise differ in how their energy is spread across pitches. What that means for masking, what research does and doesn't show, and where rain fits.
Workspace · 5 min
A cozy workspace for dark winter afternoons
When it is dark by five, your desk has to do more work. Light, warmth, sound and a few small rituals to make long winter days at a desk feel calmer.
Questions
Is Cocon free?
Yes to start: Rain, Fireplace and Snow are free, with a volume control. Cocon Pro is a one-time purchase that unlocks Storm, Forest, River, Ocean and Night Train, the visual intensity and every ambiance setting. No subscription. You can preview any locked ambiance for 30 seconds.
Can ambient sound help with stress at work?
It can help with the small, daily kind: a steady natural sound covers the interruptions that keep you on edge, and studies have linked nature sounds to faster recovery after stress. It is not a treatment for burnout. Read our five-minute desk reset.
Does Cocon slow down my Mac?
It is designed to be light: the overlay is drawn on the GPU, the animation pauses when your screen is covered by a full-screen app, and the sound uses a small set of looping recordings.
Does it work with several screens?
Yes. Each screen gets its own overlay.
Does Cocon collect any data?
No personal data. It has no account and no analytics, your settings stay on your Mac, and the only network activity is Apple’s, when you buy or restore Cocon Pro. Read the Privacy Policy.
Where can I get it?
On the Mac App Store, for macOS 14 Sonoma and later.
