How to try the 5–5 rhythm
- Let the inhale stay small, quiet, and comfortable for five counts.
- Release without pushing for the same five-count length.
- Continue only while the pace feels easier than natural breathing—not harder.
Why people call it coherent breathing
“Coherent” or “resonance” breathing commonly refers to slow, regular breathing near six cycles per minute. A five-in, five-out pattern lands exactly there. A person’s physiological resonance rate can differ, so this generic timer should not be mistaken for a personalized biofeedback protocol.
What the evidence can support
Slow-breathing studies often report changes in heart-rate variability during the exercise. A 2025 laboratory comparison found stronger HRV changes with six-breaths-per-minute patterns than with square or 4–7–8 breathing, but no meaningful short-term differences in mood or blood pressure.
That is a physiological observation, not proof that this page treats a health condition. See the project’s sources and review method.
