Alternate Nostril Breathing (Nadi Shodhana)

Reviewed by the HeyPsych Medical Review Board

Board-certified psychiatrists and mental health professionals

Indications

Primary Indications

Acute stress and anxietyDifficulty falling asleepNeed for mental centering/focusAdjunctive BP and HRV support

Mechanism

By slowing and equalizing inhalation and exhalation while alternating nasal airflow, this practice promotes vagal tone, reduces sympathetic arousal, and can improve baroreflex sensitivity and HRV. Focused attention on the breath also recruits top-down regulatory networks that modulate limbic reactivity, supporting calm and cognitive control.

Protocol

Preparation

Comfortable seated posture, spine tall; relaxed shoulders; clear nasal passages if possible.

Procedure

Position right hand in Vishnu mudra (thumb closes right nostril; ring finger closes left).
Exhale gently through both nostrils, then close the right nostril.
Inhale through the left nostril slowly (count ~4–6).
Close left nostril; open right; exhale through right (count ~4–6).
Inhale through right; close right; exhale through left. This completes one cycle.
Continue 5–10 cycles, keeping breath smooth and comfortable. Beginners avoid breath-holds; experienced users may add light retentions (e.g., 4-4-6 or 4-4-4 ratios) if well-tolerated.

Frequency: 1–2 times daily; additionally before stressful events or bedtime.

Duration: 5–10 minutes per session.

Total Treatment Time: Ongoing as a self-care practice.

Clinical Notes

Emphasize comfort over depth—no straining or noisy breathing.
Consistency matters more than session length for lasting benefits.
If nostrils are blocked, postpone or practice gentle diaphragmatic breathing instead.
