BreatheFirstPhysiological Sigh
Two inhales through the nose, one long exhale through the mouth. The fastest known way to bring a stress response down in real time. Guided, three rounds, under a minute.
Press start. Breathe with the circle.
Done. If the tightness is still there, do three more. It is safe to repeat.
Why the double inhale
- The second sip of air re-inflates collapsed air sacs in the lungs, so the long exhale that follows offloads more carbon dioxide.
- The long exhale slows the heart through the vagus nerve. Make it slow and complete.
- One to three rounds is usually enough. It is a reset button, not a practice.
