Coherent Breathing

Coherent breathing, also called resonance breathing, means breathing at about five to six breaths per minute — roughly five to six seconds in and five to six seconds out, with no holds. At this pace, for most adults, the rise and fall of heart rate with each breath becomes large and smooth. That pattern is linked to higher heart rate variability (HRV), a marker of a flexible, resilient nervous system.

You don't need to measure HRV to benefit. The practice itself — slow, even, quiet breathing for ten minutes — is the point. Research on resonance breathing has shown improvements in stress, mood and blood pressure in regular practitioners.

Breathe in through the nose for about five seconds, out through the nose for about six. Keep the breath low and quiet, as in Lesson 1. There are no holds. The transition at the top and bottom should be smooth, like a wave turning.

Ten minutes a day is the sweet spot. Morning works well because it sets the tone; evening works well because it helps you unwind. Pick one and keep it consistent.

Attach it to something fixed: after your morning coffee, before you open your laptop, when you get into bed. Use the pacer on this page, or the breathwork timer in our tools. Log each day with the 'I did the practice today' button — streaks are surprisingly motivating.

After two to four weeks, retake your control pause. Many people see it rise as their everyday breathing settles.
