Alternate Nostril Breathing — Nadi Shodhana Guide for Beginners

← Back to Blog

Alternate nostril breathing — known in yoga as Nadi Shodhana pranayama — is one of the most effective breathing techniques for quickly calming an anxious mind. Unlike many wellness trends, this one has thousands of years of practice behind it and a growing body of modern science supporting its effects on the nervous system.

If you have ever tried it, you know it works. If you have not, this guide will get you there in under five minutes.

What Is Alternate Nostril Breathing?

Nadi Shodhana (pronounced NAH-dee show-DAH-nah) translates roughly to "channel cleansing" in Sanskrit. The technique involves alternating which nostril you breathe through — closing one side while breathing through the other, in a specific pattern.

In yogic tradition, the left nostril activates calming, right-brain dominant energy, while the right nostril activates energising, left-brain dominant energy. Alternating between them is said to balance both hemispheres and the nervous system. Modern neuroscience has found interesting support for this — breathing through each nostril does appear to preferentially activate the opposite hemisphere of the brain.

How to Do Alternate Nostril Breathing

Hand position (Vishnu Mudra)

Place your right hand in front of your face. Rest your index and middle fingers on your forehead (or fold them down). You will use your right thumb to close your right nostril, and your right ring finger to close your left nostril.

The pattern — one complete cycle

That is one complete cycle. The pattern is: left in → right out → right in → left out. You always exhale through the opposite nostril from the one you inhaled through.

How Long and How Often

• Beginner: 5 cycles (about 3–4 minutes) once daily
• Intermediate: 10 cycles, morning and evening
• Advanced: Add breath retention (hold for 4–8 counts) between inhale and exhale

Most people feel a noticeable shift in their state within the first 3–5 cycles. This is one of the fastest-acting breathing techniques for mental calm.

Benefits of Alternate Nostril Breathing

Reduces anxiety immediately

Multiple studies have found significant reductions in anxiety and perceived stress after just one session of Nadi Shodhana. The controlled, slow breathing activates the parasympathetic nervous system and slows heart rate.

Improves focus and cognitive performance

Research from the Indian Journal of Physiology and Pharmacology found improved spatial memory, attention, and processing speed after regular Nadi Shodhana practice compared to control groups.

Lowers blood pressure

The slow breathing rate achieved during alternate nostril breathing (approximately 6 breaths per minute) is associated with measurable reductions in systolic blood pressure with regular practice.

Balances the nervous system

EEG studies have shown that alternating nostril breathing produces more synchronised left-right brain activity, which correlates with a calmer, more integrated nervous system state.

When to Use It

• Before a stressful meeting or exam — 5 cycles will noticeably calm the nervous system
• As a morning practice — balancing start to the day before you reach for your phone
• Before meditation — clears and settles the mind to make meditation easier
• To break an anxiety spiral — the hand position and counting give the mind something concrete to focus on
• Before sleep — ends with an exhale through the left nostril (calming side) for a relaxing finish

What Not to Do

• Do not force or strain. All breathing should feel comfortable.
• Do not practise if your nose is congested — wait until you can breathe freely through both nostrils.
• Do not add breath retention until the basic pattern feels natural.
• Do not practise immediately after eating.

Alternate Nostril vs. Other Breathing Techniques

• Alternate nostril breathing — best for balance, focus, and anxiety. Requires hands, so less discreet.
• Box breathing — best for acute stress and focus. More discreet, no hand position needed.
• 4-7-8 breathing — best for sleep. Single nostril, eyes closed.
• Cyclic sighing — best for immediate stress spike. Fastest acting, most discreet.
