Of all the breathing practices in yoga, Nadi Shodhana is the one most people could use on a Tuesday afternoon with zero prior experience. The name translates plainly: nadi means channel (the subtle pathways of the body, in the old maps), and shodhana means purification or cleansing. "Channel-clearing breath." Tradition says it balances the solar and lunar currents of the body; what a modern practitioner can verify is simpler — a few minutes of slow, alternating breath leaves you measurably less scattered.
It is the classic prelude to meditation, and for good reason: the pattern is just complicated enough to occupy the mind's fidgety surface layer, and just gentle enough to settle everything underneath.
The setup
Sit in any comfortable upright position — cross-legged on a cushion, on a chair with feet flat, even on the edge of your bed. The spine should be tall without strain. Rest the left hand on the left knee, palm up or down, whichever feels quiet.
The right hand takes Vishnu mudra: fold the index and middle fingers to the palm (or rest them lightly between the eyebrows if folding is uncomfortable — both are traditional). This leaves the thumb free to close the right nostril and the ring finger free to close the left. Use the fleshy pads, not the nails, and press just enough to seal — you are closing a door, not boarding up a window.
The basic round, step by step
One round of Nadi Shodhana
How: Exhale fully through both nostrils first. Then: close the right nostril with the thumb, inhale through the left for a count of four. Close the left nostril with the ring finger, release the thumb, exhale right for four. Inhale right for four. Close the right, release the left, exhale left for four. That — left in, right out, right in, left out — is one round.
Why: The alternation forces attention onto a moving target. You cannot run your to-do list and track which nostril is doing what at the same time, and that gentle hijacking of attention is the mechanism.
Begin with five rounds, which takes roughly two minutes. Work up to ten rounds over a few weeks. More than that is fine if it stays comfortable, but Nadi Shodhana is a settling practice, not an endurance event — five unhurried minutes is the sweet spot for most people.
Rhythm matters more than depth
Keep the breath quiet and thin — a silk thread, not a bellows. If four counts feels strained, use three. The moment you hear your breath snuffling and dragging, you have gone too deep and turned a calming practice into a workout. Some traditional versions add retention (holding after the inhale) and longer ratios like 4-4-8 or 4-8-8. There is no need to touch those for months, if ever. Even inhale, even exhale, alternating sides: that is the whole recipe, and it works.
When to use it
- Before meditation. Five rounds is the standard runway. It clears the runway of the day's mental debris so you can actually sit down and arrive, not just relocate your worries to a cushion.
- Before sleep. Done in bed, lights off, it pairs well with the Legs Up the Wall wind-down described on our sleep page.
- Before something stressful. A meeting, a hard conversation, a flight. Two minutes in a parked car or a bathroom stall is a legitimate use. Nobody can tell you are doing it if you drop the hand and just breathe through whichever nostril the pattern calls for — the effect survives the disguise.
- After practice. Ending asana with a few rounds of Nadi Shodhana instead of bolting off the mat is how you keep the calm you just built. See the breathwork overview for where it sits among the other techniques.
Common snags
The arm gets tired. Classic problem. Prop the right elbow on a cushion in your lap, or wrap the left arm around to support it. A tired shoulder will end the practice before the breath does.
One nostril is blocked. Completely normal — the body naturally cycles dominance between nostrils every couple of hours. Breathe through the open one as best you can; do not force air through a congested side. If both are stuffed from a cold, skip the practice rather than strain.
Losing track of the pattern. Everyone does, constantly, at first. The moment you notice, restart the round. The noticing is the practice — same as in meditation.

Five rounds tonight. That is the entire assignment. If the mind settles enough to sit for a while afterward, let it — and if not, you still spent five minutes doing something kind for your nervous system, which is more than most Tuesdays get.
