## What is 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.
