Nadi Shodhana: Benefits, How to Practice & What the Research Says

By Breathwork Studios · Updated June 2026 · 9 min read

Nadi Shodhana Pranayama, commonly known as alternate nostril breathing, is one of the most practised and most researched techniques in the pranayama tradition. The name comes from Sanskrit: nadi (energy channel) and shodhana (purification or cleansing). Together: the purification of the energy channels.

Sanskrit Meaning and Yogic Context

In yogic anatomy, the body contains a network of 72,000 nadis — subtle energy channels through which prana flows. The three most important are Ida (left channel, associated with lunar, cooling, calming energy), Pingala (right channel, solar, warming, activating), and Sushumna (central channel, the path of awakening).

Nadi Shodhana works by alternating the breath through the left and right nostrils, systematically activating and balancing Ida and Pingala. When these two channels are balanced, prana is said to move into Sushumna, supporting deep meditative states.

The practice is described in the Hatha Yoga Pradipika, which prescribes Nadi Shodhana as the foundational purification practice before any advanced pranayama is introduced.

Step-by-Step Instructions

1. Sit comfortably with your spine upright. Rest your left hand on your left knee.
2. Bring your right hand to Vishnu Mudra: fold the index and middle fingers toward the palm, leaving the thumb, ring finger, and little finger extended.
3. Close your right nostril with your right thumb. Inhale slowly through the left nostril for 4–6 counts.
4. Close both nostrils (right thumb, ring finger on left). Hold briefly — or skip the hold initially.
5. Release the right nostril. Exhale slowly through the right nostril for 4–6 counts.
6. Inhale through the right nostril for 4–6 counts.
7. Close both nostrils again. Hold briefly.
8. Release the left nostril. Exhale through the left nostril. This completes one cycle.
9. Continue for 5–10 cycles to start. Work toward 10–20 minutes with experience.

Benefits of Nadi Shodhana

Stress and anxiety support

Multiple studies have found that Nadi Shodhana practice may support a reduction in perceived stress and anxiety. A 2013 study in the International Journal of Yoga found that alternate nostril breathing produced significant reductions in heart rate and blood pressure compared to breath awareness alone. The extended, regulated exhale involved in the technique is thought to stimulate the parasympathetic nervous system via vagal afferent pathways.

Cognitive function

Research has explored the relationship between nostril dominance and hemispheric brain activity. Left nostril breathing is associated with right hemisphere activation; right nostril breathing with left hemisphere activation. A 2008 study found that right nostril breathing improved spatial memory tasks, while left nostril breathing improved verbal tasks. Nadi Shodhana, which alternates both, may support balanced bilateral activation.

Respiratory function

Regular practice has been associated with improved lung function markers including forced vital capacity (FVC) and forced expiratory volume (FEV1) in several studies involving yoga practitioners. The slow, extended breathing pattern strengthens the respiratory muscles and improves breath control over time.

HRV and autonomic balance

The slow, rhythmic pace of Nadi Shodhana (typically around 4–6 breaths per minute when practiced at standard counts) overlaps with the resonant frequency breathing range associated with increased heart rate variability — a marker of healthy autonomic nervous system function.

Common Mistakes

• Forcing the breath — the inhale and exhale should be smooth and comfortable, never strained. If you feel strain, shorten the count.
• Holding the breath too long too soon — extended Kumbhaka requires a foundation of comfortable breath control. Beginners should skip holds entirely.
• Slouching — the upright spine isn't aesthetic; it directly affects how freely the diaphragm moves and how open the airways are.
• Using the wrong hand mudra — pinching the nose with thumb and forefinger works but loses the precision of Vishnu Mudra, which provides cleaner individual nostril control.
• Breathing through the mouth — this defeats the purpose. If nasal breathing is difficult due to congestion, wait until the nasal passages are clear.

Variations

• Anuloma Viloma — similar to Nadi Shodhana but with longer breath ratios (typically 1:4:2 — inhale:hold:exhale) and always includes Kumbhaka. Considered a more advanced form.
• Surya Bhedana — always begins by inhaling through the right nostril; warming and activating. Used when more energy is needed.
• Chandra Bhedana — always begins through the left nostril; cooling and calming. Used when more rest is needed.

Contraindications

Nadi Shodhana in its simple form (without breath retention) is one of the safest pranayama techniques and is suitable for most people. Approach with care if you have:

• Severe nasal congestion or deviated septum making nostril breathing difficult
• Recent nasal surgery
• Uncontrolled hypertension (avoid breath retention specifically)
• Pregnancy (avoid breath retention; the simple alternating form is generally considered safe)
