Cyclic Sighing (The Physiological Sigh)
A rapid stress-relief technique involving a double inhalation followed by an extended exhalation. It quickly lowers autonomic arousal and promotes an immediate sense of calm.
- 1Sit or lie down in a comfortable, relaxed position.
- 2Take a deep, full breath in through your nose until your lungs are almost full.
- 3Take a second, quick sip of air through your nose to maximally expand the lungs.
- 4Exhale slowly and completely through your mouth, ensuring the exhale is longer than the total inhale.
- 5Repeat this cycle continuously for 3 to 5 minutes.
The double inhalation mechanically reinflates collapsed alveoli in the lungs, maximizing the surface area for oxygen and carbon dioxide exchange. The subsequent extended exhalation stimulates the vagus nerve, which decreases heart rate and rapidly shifts the autonomic nervous system from a sympathetic (fight-or-flight) state to a parasympathetic (rest-and-digest) state.
