What it does
Uses a double inhale (one long inhale through the nose immediately followed by a second, shorter sharp inhale on top of it) followed by a long, slow exhale — a pattern the body already does naturally during crying or after sighing, shown in research (including Stanford-affiliated studies) to offload carbon dioxide and lower physiological arousal unusually quickly.
How to practice
- 1Inhale deeply through the nose until the lungs feel mostly full.
- 2Without exhaling, take a second, quick, sharp inhale through the nose to top off the lungs further.
- 3Exhale slowly and completely through the mouth, taking noticeably longer than the two inhales combined.
- 4Repeat for 1-3 cycles — this technique works quickly and doesn't usually need many repetitions.
When it helps
Sudden spikes of stress or anxiety, needing a fast reset in the middle of a difficult moment, situations where a longer practice isn't practical.
Benefits
Works faster than many other techniques for rapidly lowering physiological arousal in the moment; simple enough to do with eyes open, mid-conversation, or during a stressful task; doesn't require a quiet or private setting.
A note on safety
The double inhale can feel unfamiliar at first — go slowly the first few times rather than inhaling forcefully, and stop if it triggers coughing or discomfort.
