How to Practice
Inhale smoothly through your nose for 4 seconds, hold gently for 4 seconds, exhale slowly for 6 seconds, and pause in quiet stillness for 2 seconds before breathing in again.
The Biology of the Cadence
The combination of mindful retention followed by extended exhalation induces hyperpolarization currents in neural tissue, shifting autonomic control toward deep restorative parasympathetic dominance. This lowers systemic vascular resistance, encouraging skeletal muscles in the jaw, neck, and lower back to unclench.
- •Specifically targets somatic muscle tension held after intense work or physical exercise.
- •Pre-conditions the nervous system for slow-wave deep sleep.
- •Gentle and accessible for extended evening sessions.
When to Use This Cadence
- •Unwinding in the evening before reading or going to bed.
- •Post-workout somatic recovery and muscle relaxation.
- •Transitioning into yoga nidra, meditation, or body-scan practices.
Posture
Recline comfortably on a sofa or bed with supported knees, or sit in a comfortable armchair with a relaxed neck and jaw.
Nasal Path
Slow nasal inhalation, peaceful retention, unhurried nasal or pursed-lip exhale, and quiet restorative rest.
Reference Notes
Medical Hypotheses (2006) — Jerath et al. demonstrated that pranayama rhythms with prolonged exhalations stimulate pulmonary vagal afferents, shifting autonomic tone toward restorative parasympathetic dominance.
