Anulom Vilom: Alternate-Nostril Breathing, Step by Step

The easiest practice to learn badly

Of all the breathing practices India has given the world, anulom vilom — alternate-nostril breathing — is the easiest to learn badly, because it looks like nothing more than closing nostrils in turn. Done properly, it is a structured way of slowing the breath to five or six long cycles a minute while giving the restless mind a task to hold. The slow, extended exhalation is the active ingredient: a long breath out stimulates the vagus nerve, the main cable of the body's rest-and-repair system, which eases heart rate and dials down the stress response. The nostril-switching supplies rhythm and attention; the slowness supplies the physiology.

Setting up: seat, spine and hand

Sit anywhere you can be upright and still for ten minutes — cross-legged on a mat, or equally well on a firm chair with feet flat, since a chair changes nothing about the breathing. Lengthen the spine, drop the shoulders, and rest the left hand on the thigh. Fold the right hand into what tradition calls Vishnu mudra: index and middle fingers curled into the palm, leaving the thumb free to close the right nostril and the ring finger free to close the left. The touch on the nose should be a feather's pressure on the soft part of the nostril, just enough to close it — pressing hard bends the septum, blocks both sides and guarantees strain.

The sequence itself

One full round runs like this: close the right nostril with the thumb and breathe in slowly through the left; then close the left with the ring finger, release the thumb, and breathe out slowly through the right; breathe in through the same right nostril; close it, release the left, and breathe out through the left. That is one round — in left, out right, in right, out left. Keep the breath silent, smooth and unhurried, with the exhalation at least as long as the inhalation; many teachers suggest working towards an exhale roughly twice the inhale, such as four counts in and six to eight counts out. Begin with five minutes and let the count lengthen naturally over weeks.

The mistakes that undo the benefit

Watch for five habits. Forcing the breath — audible, effortful breathing defeats the purpose, since the nervous system reads strain as stress; the breath should feel like pouring water, not pushing it. Collapsing the chest as the session goes on, which shortens the breath; re-lengthen the spine whenever you notice. Gripping the nose, which blocks airflow entirely. Racing the count to finish, which turns a calming practice into a task. And adding long breath-holds too early: classical versions include retention (kumbhaka), but beginners gain nothing and risk dizziness by holding; the slow in-and-out alone delivers the benefit, and retention, if ever, comes much later under a teacher's eye.

When to practise, and what to expect

The practice fits best on a mostly empty stomach — early morning before breakfast, or a gap of two to three hours after a meal — because a full belly presses on the diaphragm and shortens the breath. Morning practice steadies the day; a gentler evening round helps some people unwind before sleep. Expect modest, cumulative effects rather than fireworks: most regular practitioners report calmer reactivity, easier sleep onset and a slower resting breath within a few weeks. What it will not do is cure asthma, dissolve blood pressure medication or replace treatment for anxiety disorders — it is a daily maintenance tool for the nervous system, valuable precisely because it is repeatable.

Who should modify, and who should wait

A blocked nose changes the plan: with a cold or heavy allergy, forcing air through swollen passages is unpleasant and pointless, so switch to slow plain breathing through whichever passage is open, and return to the alternate pattern when the nose clears. People with uncontrolled blood pressure, heart disease, or a recent heart attack or surgery should keep the practice gentle and entirely skip breath-holding, which spikes chest pressure — the same rule applies in pregnancy, where slow alternate breathing without retention is generally considered fine. After recent nose or ear surgery, ask your surgeon first. Children can learn a soft version; the elderly can practise seated on a chair without any compromise.

Signals to stop, and when to ask a doctor

Mild lightheadedness at the start usually means you are over-breathing — pausing and returning to natural breath settles it within a minute, and slower, softer rounds prevent it. Stop the session for spinning dizziness, tingling around the mouth or fingers, chest pain, or breathlessness that worsens rather than eases, and mention any of these to a doctor if they recur. One-sided nasal blockage that never alternates, frequent nosebleeds, or snoring with daytime sleepiness deserve a proper check-up in their own right — a deviated septum or sleep apnoea will not be fixed by any breathing pattern. For everyone else, the practice is among the safest ten-minute habits available.
