Rumi Breathing

Most people breathe 25,000 times a day. Almost all of them wrong. Rumi Breathing is a science-based practice companion built on James Nestor's landmark research into nasal breathing, CO₂ tolerance, and the lost art of breathing well. BREATHE Guided patterns — Resonance, Coherent, Box, 4-7-8, and more. Breathing at 5.5 breaths per minute synchronises your heart rate variability to its resonance frequency. The effect on HRV, blood pressure, and anxiety is measurable within a single session. LEARN A science library built from Nestor's research: nitric oxide, the Bohr Effect, the Stanford experiment, and the mouth-breathing epidemic reshaping modern skulls. TRAIN Daily exercises and multi-day programs: Nose Unblocking, CO₂ Tolerance, Mouth Tape, and Breath Awareness. MEASURE The BOLT Score reveals your CO₂ tolerance — the single most predictive measure of breathing efficiency. Track it over time. Your nose is a pharmacy. Start using it.
