Alternate nostril breathing is a pranayama technique in which you close one nostril at a time with your fingers, breathing in and out through each side in a set rhythm. In Sanskrit it is known as Nadi Shodhana, meaning “channel purification” — a classical practice designed to clear and balance the energy channels described in yogic anatomy. It is one of the oldest and most widely taught breathing exercises in yoga, valued for its calming, balancing effect on both body and mind.
This guide walks through exactly how to practice it, what the Sanskrit name actually means, the benefits research and practitioners report, how it differs from the closely related technique Anulom Vilom, and the mistakes that most often trip up beginners.
Step-by-Step: How to Practice Alternate Nostril Breathing
1. Find Your Seat
Sit upright in a comfortable position — Easy Pose, Lotus Pose, Hero Pose, or simply Staff Pose with your back supported. A tall, relaxed spine allows the breath to move freely. Rest your left hand on your left knee, palm up or in a light gyan mudra.
2. Form Vishnu Mudra
With your right hand, fold your index and middle fingers down toward the palm, leaving the thumb, ring finger, and pinky extended. This is Vishnu Mudra, the hand position used to open and close the nostrils throughout the practice. The thumb will control the right nostril; the ring finger will control the left.
3. Begin With an Exhale
Close your right nostril with your thumb and exhale completely through the left nostril, emptying the lungs.
4. Complete One Full Cycle
- Inhale slowly through the left nostril for a count of 4.
- Close the left nostril with your ring finger, release the thumb, and exhale through the right nostril for a count of 4.
- Inhale through the right nostril for a count of 4.
- Close the right nostril with your thumb, release the ring finger, and exhale through the left nostril for a count of 4.
That sequence — left in, right out, right in, left out — is one complete round.
5. Add Retention (Optional)
Once the basic rhythm feels natural, you can pause briefly with both nostrils closed after each inhale, holding for a count of 4 before exhaling. This retention (kumbhaka) is the traditional element that distinguishes full Nadi Shodhana from its simpler cousin, Anulom Vilom.
6. Practice 5 to 10 Rounds
Continue for 5 to 10 rounds, keeping every phase — inhale, hold, exhale — as close to equal length as possible. Use a light touch on the nostrils; there is no need to press hard. Finish by lowering the hand and sitting for a few breaths of natural, unassisted breathing before returning to your day.

The Meaning Behind It: Nadis, Ida, and Pingala
Nadi Shodhana’s name comes from two Sanskrit words: nadi, meaning “channel,” and shodhana, meaning “purification” or “cleansing.” In yogic anatomy, the body is said to contain thousands of subtle energy channels, or nadis, through which prana (vital life force) flows. Two of these are considered especially important: Ida, the “lunar” channel associated with the left nostril and a calming, introspective quality, and Pingala, the “solar” channel associated with the right nostril and an energizing, active quality.
According to this framework, everyday stress, poor posture, and irregular breathing habits create imbalances between Ida and Pingala — leaving a person either overstimulated or sluggish. By deliberately alternating the breath between nostrils, Nadi Shodhana is designed to bring these two channels into equilibrium, allowing prana to flow more freely through the central channel, Sushumna. Whether or not you relate to this system in literal terms, the underlying idea — using breath to shift between activating and calming states — maps closely onto what modern physiology calls sympathetic and parasympathetic balance.
Benefits of Alternate Nostril Breathing
Practitioners report a range of effects from regular alternate nostril breathing practice, and small studies on nostril breathing techniques point in similar directions:
- A sense of calm and reduced stress. Slow, even nasal breathing is associated with increased parasympathetic activity, and many practitioners describe feeling noticeably steadier after just a few minutes.
- Improved focus. The mental attention required to track the counting and hand movements naturally interrupts rumination and scattered thinking, which many people experience as sharpened concentration afterward.
- A subjective sense of balance. Because the technique alternates evenly between both nostrils, practitioners often describe feeling more centered — neither wired nor drowsy — which is consistent with its traditional role as a balancing (rather than purely calming or purely energizing) practice.
- Better breath awareness. Regular practice trains you to notice shallow, rushed, or uneven breathing patterns in daily life, which is often the first step toward correcting them.
These are subjective and small-study findings rather than established medical treatments — alternate nostril breathing is best approached as a wellness and stress-management practice, not a substitute for medical care.
Nadi Shodhana vs Anulom Vilom: What’s the Difference?
These two names are often used interchangeably, but there is a meaningful distinction. Anulom Vilom is the simpler, more beginner-friendly version: you alternate the breath between nostrils continuously, with no pause between inhale and exhale. Full Nadi Shodhana adds breath retention (kumbhaka) — a brief hold with both nostrils closed after each inhale — which increases the intensity and meditative depth of the practice.
In practice, many teachers use the two names loosely, and some traditions consider Anulom Vilom simply the “practice” phase you build before adding retention. If you are new to nostril breathing, start with the no-retention version and add holds only once the basic rhythm feels effortless.
Related Nostril-Specific Techniques
Nadi Shodhana balances both channels equally, but two related pranayamas isolate a single nostril for a specific effect:
- Surya Bhedana — inhaling exclusively through the right nostril to stimulate energy and warmth, best suited to morning practice.
- Chandra Bhedana — inhaling exclusively through the left nostril to promote cooling and calm, well suited to evening practice.
Understanding how these three techniques relate makes it easier to choose the right one depending on whether you need balance, energy, or calm.
When to Practice
Alternate nostril breathing is unusually versatile. Many practitioners use it at the start of a session to settle the mind before asana or meditation, at the end of a session to integrate the effects of practice, or as a short standalone reset during a stressful moment in the day. Because it is gentle and requires no props, it also works well before sleep, though those seeking a more directly calming effect before bed may prefer to favor left-nostril-dominant breathing, such as Chandra Bhedana.

Common Mistakes to Avoid
Pressing too hard on the nostrils. A light touch is all that is needed. Pressing firmly creates tension in the hand, wrist, and face that works against the relaxing intent of the practice.
Rushing the counts. The goal is even, unhurried breathing, not speed. If you find yourself gasping to keep pace, slow the count down or drop the retention until your capacity builds.
Forcing air through a blocked nostril. If one side is significantly more congested than the other, don’t force it — breathe naturally for a few rounds, or try lying briefly on the opposite side, which can help the blocked nostril open before continuing.
Tensing the shoulders or jaw. Keep the shoulders relaxed and away from the ears, and the jaw and tongue soft. Tension here defeats the calming purpose of the technique.
Skipping the settling period. Jumping straight from alternate nostril breathing into activity without a few breaths of natural, unassisted breathing can undercut the calming effect. Give yourself a moment to simply sit before moving on.
Frequently Asked Questions
How long should I practice alternate nostril breathing? Five to ten rounds (roughly five minutes) is a reasonable starting point. Many practitioners extend this to ten to fifteen minutes as their comfort with the technique grows.
Can I practice it every day? Yes — it is considered safe for daily practice by most yoga traditions and is often recommended as a foundational technique to return to regularly, whether as a standalone practice or bookending an asana session.
Is it normal for one nostril to feel more open than the other? Yes. The nasal cycle — a natural, gradual shift in airflow dominance between the two nostrils over the course of a few hours — means one side is often more open than the other at any given time. This is a normal physiological pattern, not a sign that anything is wrong.
Do I need to use my fingers, or can I just visualize it? The physical hand position and gentle finger closure are traditionally considered part of the technique, helping create the precise, controlled airflow the practice relies on. A purely visualized version is possible but produces a different, less structured experience.
A brief caution: if you have significant nasal congestion, a cold, or a diagnosed respiratory condition, breathe gently and consider skipping the retention phase — or the practice altogether — until you have recovered or spoken with a healthcare provider.
