A practice for the modern mind

Breathe. Pause. Decide.

C-Breath is a quiet companion for the moments that matter — when panic rises, when focus slips, when a hard choice waits on the other side of one slow breath.

Designed by the Center for Behavioral Decisions

"You don't need a perfect breath — just keep going."

— a daily quote from C-Breath

Six sessions, one anchor

A breath for every moment.

Each session uses a clinically-grounded rhythm — extended exhales, balanced holds, deliberate pauses — tuned to a specific need.

Panic Relief

4 · 4 · 8

An extended-exhale technique that gently signals safety to the nervous system. For the moments the storm hits hardest.

Relaxation

4 · 4 · 4 · 4

A pause button for a busy day. Soft, balanced cycles to release tension from shoulders, jaw, and mind.

Focus

4 · 3 · 4 · 1

Steady alertness without strain. Use before a deep work block, an exam, or a difficult conversation.

Reducing Stress

4 · 4 · 4 · 4

Classic box breathing. Four equal parts to find balance — a reset for the moments between meetings.

Resilience

4 · 6 · 6 · 4

Composure under pressure. Deliberate pauses that train the body to stay calm when the stakes are real.

Insightful Decisions

4 · 8 · 6 · 2

Long holds create space to think. For the choices that deserve a clear head — not a fast answer.

Grounded in research

Built on the science of the slow breath.

The extended exhale activates parasympathetic tone via the vagus nerve, lowering heart rate and signaling safety to the brain. Each protocol draws on peer-reviewed research in respiratory physiology and behavioral medicine.
