Nadi Shodhana — Channel Purifying Breath
Nadi Shodhana is an advanced Pranayama technique that combines alternate nostril breathing with breath retention (kumbhaka). It systematically purifies the 72,000 nadis (energy channels), balances the ida and pingala, and creates profound mental stillness and clarity.
Quick Overview
Nadi Shodhana (channel purification) is an advanced alternate nostril breathing technique that includes kumbhaka (breath retention) and follows specific ratios. It systematically purifies the energy channels, bringing deep balance to the mind and preparing the practitioner for advanced meditative states.
What Is Nadi Shodhana?
Nadi Shodhana is derived from Nadi (energy channel) and Shodhana (purification). According to yogic philosophy, there are 72,000 nadis in the subtle body through which prana flows. Blockages in these channels lead to physical, mental, and energetic imbalances. Nadi Shodhana uses a precise pattern of alternate nostril breathing with retention to clear these blockages. Unlike Anulom Vilom (which alternates without retention), Nadi Shodhana incorporates kumbhaka and follows specific ratios (typically 1:4:2 of inhalation, retention, exhalation).
Benefits of Nadi Shodhana
Purifies Energy Channels
The systematic breath pattern clears blockages in all 72,000 nadis, allowing free flow of prana.
Deep Mental Calm
Extended exhalation and retention activate the parasympathetic nervous system, creating profound stillness.
Improves Concentration
The focused practice of counting and breath control develops deep mental discipline and one-pointed focus.
Balances Brain Hemispheres
Alternate nostril breathing synchronises the left and right hemispheres, promoting whole-brain integration.
Supports Respiratory Health
The retention phase strengthens respiratory muscles and improves carbon dioxide tolerance.
Deepens Meditation
Nadi Shodhana directly prepares the mind for deep meditation by stilling mental fluctuations.
Regulates Emotions
Balances the nervous system, reducing emotional reactivity and promoting emotional stability.
Increases Vitality
Clear nadis allow prana to flow freely, increasing overall vitality and well-being.

Step-by-Step Practice
Close the Right Nostril
Use your right thumb to close the right nostril. Inhale through the left nostril for 4 seconds.
Close Both Nostrils — Hold
Close both nostrils. Hold the breath for 16 seconds (or a comfortable duration).
Exhale Through the Right
Release the right nostril, keep the left closed. Exhale through the right for 8 seconds.
Inhale Through the Right
Keep the left nostril closed. Inhale through the right nostril for 4 seconds.
Close Both Nostrils — Hold
Close both nostrils again. Hold the breath for 16 seconds.
Exhale Through the Left
Release the left nostril, keep the right closed. Exhale through the left for 8 seconds.
Complete One Round
Left inhale → hold → right exhale → right inhale → hold → left exhale. This is one round.
Repeat for 5 to 10 Rounds
Start with 3 to 5 rounds and gradually increase to 10 rounds as your capacity builds.
Breathing Pattern
Nadi Shodhana traditionally follows a 1:4:2 ratio of inhalation (puraka), retention (kumbhaka), and exhalation (rechaka). Beginners start with a 4:8:8 or 4:8:6 ratio and work up to 4:16:8.
Common Mistakes
Attempting Too Advanced Ratios
Never force a ratio. The retention should always be comfortable. Work up gradually.
Straining During Retention
If you feel tension or gasping after retention, reduce the hold duration.
Rushing the Breath
Each phase should be smooth and controlled. Rushing reduces the effectiveness.
Inconsistent Nostril Switching
Maintain awareness of which nostril should be open at each phase.
Tensing the Body
Keep the body relaxed, especially the face, jaw, and shoulders throughout the practice.
Safety Precautions
Never Force Retention
Retention should be comfortable and effortless. If you feel distress, reduce the hold time.
Stop If Dizzy
If you feel lightheaded or dizzy, return to normal breathing.
Master Anulom Vilom First
Do not attempt Nadi Shodhana until you are comfortable with Anulom Vilom.
Consult for Medical Conditions
Those with blood pressure, heart, or respiratory conditions should consult a doctor first.
Empty Stomach Mandatory
Wait at least 4 hours after a meal before practising.
Best Time to Practice
Early morning (Brahma Muhurta — 4:00 to 6:00 AM) on an empty stomach is ideal. The quiet energy of dawn supports the introspective nature of this practice. Avoid practising after meals or late at night.
