Nadi Shodhana: A Complete Guide to Alternate Nostril Breathing

Quick Intro

Nadi Shodhana (Alternate Nostril Breathing in English) is a Breathwork / Pranayama exercise performed by using one hand to close and open each nostril in turn, so the breath’s route through the nose changes with every phase of the cycle rather than staying fixed the way it does in a plain paced breath. A specific hand shape called Vishnu mudra does the closing: the thumb seals the right nostril and the ring finger seals the left, while the index and middle fingers fold into the palm out of the way.

Equipment Needed

Nothing is required to practice Nadi Shodhana. A yoga mat is optional, useful only for a little cushioning if seated on a hard floor.

Why Nadi Shodhana Matters

Coordination is the main demand here, and it is a mental kind of coordination more than a physical one: tracking which nostril is open, which finger is closing it and which phase of the cycle comes next, all while keeping the breath itself silent and unforced. The slow, counted breath and its holds also build control over the pace of breathing, as any paced technique does. It asks for little else, since there’s no forceful pumping or physical exertion involved, just a precise, repeated hand-and-breath sequence.

When to Do It

Nadi Shodhana sits above breathwork’s simplest paced techniques but well short of anything physically demanding, making it a good fit before meditation, before sleep or any time a few minutes of focused, unhurried attention are available. Because the hand position needs to be learned before the breath can flow smoothly through it, a first practice session is better spent slower and shorter than a later one.

Getting Ready

Rehearsing the Vishnu mudra hand shape on its own, away from the breath entirely, is worth doing before combining it with anything: fold the index and middle fingers down into the palm, then check that the thumb and ring finger land cleanly on either side of the nose without needing to hunt for the right spot mid-cycle. A few slow, ordinary breaths through both nostrils beforehand also gives a baseline for how open each side feels before deliberately closing one at a time.

Step-by-Step Instructions

1. Sit tall with the spine upright, and raise the right hand into Vishnu mudra, thumb and ring finger extended, index and middle fingers folded into the palm.
2. Close the right nostril with the thumb and inhale slowly through the left nostril for a count of 4.
3. Close both nostrils and hold the breath in for a count of 4.
4. Release the thumb, close the left nostril with the ring finger and exhale through the right nostril for a count of 4.
5. Inhale through the right nostril for a count of 4, then close both nostrils again and hold for a count of 4.
6. Release the ring finger, close the right nostril with the thumb and exhale through the left nostril for a count of 4, completing one full cycle.
7. Repeat the cycle continuously, keeping the breath silent throughout.

How Many, How Often

Nadi Shodhana is dosed by the number of complete cycles in a sitting rather than a fixed session length, since each cycle is a self-contained round through both nostrils.

The switch between nostrils staying clean and silent matters more here than rushing toward a longer ratio before that switch feels automatic.

Modifications and Variations

Nadi Shodhana carries two variations, one easier and one harder.

Easier: Nadi Shodhana — No Retention. Removing the hold between the inhale and exhale takes away the one phase most likely to cause fumbling with the hand position early on, leaving just the alternating breath itself.

Harder: Nadi Shodhana — Extended Ratio. Stretching the hold and exhale out relative to the inhale, working toward the traditional 4-16-8 count, asks for much more breath control once the basic switching pattern is already automatic.

Both variations keep the same alternating-nostril mechanic and change only how much timing precision the cycle demands.

Common Mistakes to Avoid

Forcing or straining the breath. The breath should stay silent and unforced through every phase, and any audible strain means the pace has outrun what feels comfortable.

Losing track of which nostril comes next. With four separate phases per cycle, it’s easy to inhale on the wrong side or forget which finger is currently pressing which nostril, breaking the alternating pattern that gives the technique its name.

Switching hands or grip mid-practice. Changing which hand holds the mudra partway through a session interrupts the muscle memory being built and makes the sequence harder to keep automatic.

After Your Set

There’s no physical hold to release afterward, since nothing but the hand and the breath were engaged. Letting the hand rest and breathing normally through both nostrils together for a minute is worth doing anyway, partly to notice whether one side felt more open than the other during the practice, a common and harmless variation in how the nose naturally cycles through congestion over the course of a day.

Going Deeper

Once the basic 4-4-4 cycle flows without hesitation, the next step is extending the ratio toward 4-16-8 as mastery builds. Progress here tends to stall on the hold and exhale phases specifically, since a longer hold is where the breath is most tempted to sneak out early or turn strained. Getting the hand switch silent and automatic, with zero pause to think about which finger goes where, is a better marker of progress than how long any single hold lasts.

How to Know You’re Improving

1. The hand switches nostrils cleanly, without pausing to think about which finger closes which side.
2. The breath stays completely silent through every phase, including the holds.
3. A full 4-4-4 cycle feels calm and unhurried, never rushed.
4. The hold and exhale phases extend comfortably toward a 4-16-8 ratio without straining.
5. A full session leaves a noticeably calmer, more settled feeling than before it started.

Muscles Worked

• Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, metering the exhale so each count lands evenly)
• Serratus Anterior (a muscle along the side of the ribcage, expanding the ribs on an inhale restricted to one nostril)
• Scalenes (a group of smaller muscles along the side of the neck, lifting the upper ribs as the narrowed airway slows the inhale)

FAQ

Does Nadi Shodhana work both nostrils at the same time? Both nostrils are worked, but never at the same moment, since only one is ever open at a time. That alternating, one-side-then-the-other pattern is what sets it apart from a technique that breathes through both nostrils together the entire time.

Is Nadi Shodhana the same as Anuloma Viloma? The two names are commonly used for the same alternating-nostril pattern, and the version described here matches the standard practice both names refer to.

What if one nostril feels blocked? A partially blocked nostril is common and usually still allows some airflow, so the practice can continue at a gentler pace on that side. If a nostril is fully blocked, waiting until it clears is more useful than forcing air through it.

Can this be done lying down? It’s built around a seated posture so the hand can reach the nose comfortably and the spine can stay tall, so a seated position works better than lying down for this particular technique.

How is this different from Box Breathing? Box Breathing keeps both nostrils open throughout and varies only the timing of the four phases, while Nadi Shodhana’s defining feature is the alternating nostril itself, guided by hand position rather than by count alone (see Step-by-Step Instructions above).
