Somatic Wave Breathwork: How the Physiological Sigh Cools Down Panic & Stress
When stress or digital overload triggers autonomic arousal, alveoli in your lungs collapse, causing carbon dioxide ($CO_2$) to build up in your bloodstream.
The Physiological Sigh—discovered by neurobiologists—is the fastest real-time mechanism to pop open collapsed alveoli and lower heart rate.
How to Perform the Physiological Sigh
- Inhale 1: Take a deep inhale through your nose.
- Inhale 2: Without exhaling, take a sharp top-off second inhale to pop open collapsed alveoli.
- Exhale: Slowly offload carbon dioxide with a long, relaxed exhale through your mouth.
