How to use it

  1. Inhale through the nose
    A normal, comfortable breath in.
  2. Add a second short inhale
    A small sip on top to fill the lungs.
  3. Long, slow exhale
    Let it out through the mouth. A few in a row can lower arousal quickly.

Why it works

The double inhale reinflates collapsed air sacs and the long exhale nudges the body toward calm. It is the fastest studied reset. Read more about the physiological sigh and breathing safety.
