Anulom Vilom Pranayama: Complete Guide to Alternate Nostril Breathing

Master the ancient art of alternate nostril breathing to balance your nervous system, calm your mind, and harmonize the flow of prana through the energy channels.

What is Anulom Vilom Pranayama?

Anulom vilom pranayama is one of the most widely practiced and deeply respected yogic breathing techniques. The name comes from Sanskrit: "anulom" means "with the natural order" or "along the grain," and "vilom" means "against the natural order" or "against the grain." Together, the term describes the practice of breathing alternately through the left and right nostrils in a rhythmic, balanced pattern.

In the yogic understanding of the body, the left nostril is connected to Ida nadi (the lunar energy channel associated with cooling, calming, and the right hemisphere of the brain), while the right nostril is connected to Pingala nadi (the solar energy channel associated with heating, activating, and the left hemisphere of the brain). When the breath flows evenly through both nostrils, the central energy channel — Sushumna nadi — becomes active, creating the optimal conditions for meditation and spiritual practice.

Anulom vilom is often described as the foundational nadi purification practice. In the Hatha Yoga Pradipika, Swatmarama teaches that the nadis (energy channels) of most people are blocked by impurities, preventing the smooth flow of prana. Through systematic practice of alternate nostril breathing, these blockages are gradually cleared, and the flow of prana becomes balanced and harmonious. The text states: "When the nadis are purified, there are external signs: the body becomes lean, the face glows, the inner sounds become audible, and diseases are eliminated."

Anulom Vilom vs. Nadi Shodhana: Understanding the Difference

Many practitioners and even some yoga teachers use the terms "anulom vilom" and "nadi shodhana" interchangeably, but they refer to related yet distinct practices. Understanding the difference is important for safe and effective practice.

Anulom Vilom

  • Alternate nostril breathing without breath retention
  • Continuous flow: inhale left, exhale right, inhale right, exhale left
  • Suitable for all levels including complete beginners
  • Emphasis on balancing the breath and purifying the nadis
  • Can be practiced independently without a teacher

Nadi Shodhana

  • Alternate nostril breathing with breath retention (kumbhaka)
  • Includes antara kumbhaka (internal hold) and sometimes bahya kumbhaka (external hold)
  • Intermediate to advanced practice
  • Emphasis on deepening the energetic effects and awakening kundalini
  • Should be learned under the guidance of an experienced teacher

In practice, anulom vilom serves as the preparatory stage for the more advanced nadi shodhana. Most teachers recommend mastering anulom vilom for several months before introducing breath retention. At Anantadrishti Yoga, we teach both practices as part of a progressive pranayama curriculum, ensuring each student advances safely and at the appropriate pace.

How to Practice Anulom Vilom: Step-by-Step Instructions

Follow these seven steps to practice anulom vilom correctly. The technique is safe for all levels, though advanced ratios should be developed gradually.

  1. 1

    Sit in a comfortable, stable posture

    Choose a seated posture such as Sukhasana (easy pose), Padmasana (lotus pose), or Siddhasana (adept pose). You may also sit on a chair with your feet flat on the floor. Keep your spine erect, shoulders relaxed, and the crown of the head reaching upward. Rest your left hand on your left knee in Jnana Mudra (tip of index finger touching the tip of the thumb, other fingers extended).

  2. 2

    Form Vishnu Mudra with your right hand

    Bring your right hand up to your face. Fold the index and middle fingers toward the palm, keeping the thumb, ring finger, and little finger extended. This is Vishnu Mudra (also called Nasagra Mudra), the traditional hand position for alternate nostril breathing. Your right thumb will control the right nostril, and your right ring finger will control the left nostril.

  3. 3

    Close the right nostril and inhale through the left

    Gently press your right thumb against the right nostril to close it. Inhale slowly, smoothly, and deeply through the left nostril. The inhalation should be silent, steady, and controlled. Fill your lungs completely without strain. If you are a beginner, count to 4 during the inhalation. Maintain awareness of the breath flowing through the left nostril.

  4. 4

    Close the left nostril and exhale through the right

    At the top of the inhalation, close the left nostril with your ring finger. Release the right nostril by lifting the thumb. Exhale slowly, smoothly, and completely through the right nostril. The exhalation should be slightly longer than the inhalation if possible. For beginners, count to 4 (or up to 6) during the exhalation. Empty the lungs fully without forcing.

  5. 5

    Inhale through the right nostril

    Keeping the left nostril closed with the ring finger, inhale slowly and deeply through the right nostril. Match the length and quality of this inhalation to the previous one. The breath should be smooth and continuous, without any jerks or pauses. Maintain the same count you used for the left nostril inhalation.

  6. 6

    Close the right nostril and exhale through the left

    Close the right nostril with the thumb. Release the left nostril by lifting the ring finger. Exhale slowly and completely through the left nostril. This completes one full round of anulom vilom. The exhalation should be smooth, controlled, and slightly longer than the inhalation.

  7. 7

    Continue for 5 to 15 minutes

    Repeat the cycle: inhale left, exhale right, inhale right, exhale left. Begin with 5 minutes (approximately 8 to 10 rounds) and gradually increase to 15 to 20 minutes as your capacity develops. After completing your practice, lower the right hand, rest both hands on the knees, and sit quietly for 1 to 2 minutes with natural breathing. Observe the effects of the practice on your mind and body.

Benefits of Anulom Vilom Pranayama

Consistent practice of anulom vilom produces profound benefits across the physical, mental, and energetic dimensions of health. Many of these benefits are supported by modern clinical research.

Balances Brain Hemispheres

Research shows that alternate nostril breathing balances activity between the left (logical) and right (creative) hemispheres of the brain, enhancing whole-brain function and cognitive flexibility.

Reduces Stress and Anxiety

The slow, rhythmic breathing pattern activates the parasympathetic nervous system, significantly reducing cortisol levels, heart rate, and subjective anxiety within minutes of practice.

Improves Respiratory Function

Regular practice strengthens the diaphragm, increases vital lung capacity, and improves the efficiency of gas exchange. Studies show improved pulmonary function test results after 6 to 12 weeks of regular practice.

Regulates Blood Pressure

Multiple clinical trials have demonstrated that anulom vilom practice significantly reduces both systolic and diastolic blood pressure through its effects on the autonomic nervous system.

Enhances Sleep Quality

Practicing anulom vilom before bedtime shifts the nervous system into rest-and-digest mode, helping to quiet racing thoughts and promote deeper, more restorative sleep.

Balances the Nervous System

By alternating between the solar (sympathetic) and lunar (parasympathetic) energy channels, anulom vilom creates autonomic equilibrium — the ideal state for health and wellbeing.

Increases Oxygen Flow

The deep, controlled breathing pattern maximizes oxygen intake and carbon dioxide removal, improving cellular oxygenation throughout the body and enhancing energy levels.

Boosts Immune Function

Deep, slow breathing stimulates the lymphatic system and has been shown to increase the activity of natural killer cells and other immune markers.

Purifies the Nadis

According to yogic physiology, anulom vilom clears blockages in the 72,000 nadis (energy channels), allowing prana to flow freely and creating the foundation for advanced practices.

Prepares for Meditation

By calming mental fluctuations and balancing the energetic body, anulom vilom creates the ideal conditions for dharana (concentration) and dhyana (meditation).

Duration and Breathing Ratios

The duration and breathing ratio you use for anulom vilom should be based on your experience level and comfort. Progressing too quickly can cause strain, headaches, or dizziness. Always prioritize smooth, comfortable breathing over achieving a longer count.

Beginner Level (Weeks 1-8)

Duration: 5 minutes per session (8-10 rounds)

Ratio: 1:1 (inhale 4 counts, exhale 4 counts). Focus on smooth, even breathing without any strain. Practice once or twice daily.

Intermediate Level (Weeks 8-24)

Duration: 10-15 minutes per session (15-20 rounds)

Ratio: 1:2 (inhale 4 counts, exhale 8 counts). The longer exhalation deepens the calming effect and strengthens the diaphragm. Practice once or twice daily.

Advanced Level (6+ months with a teacher)

Duration: 15-20+ minutes per session

Ratio: 1:1:2 or 1:2:2 or 1:4:2 (with kumbhaka/retention — this transitions the practice into Nadi Shodhana). Only practice under direct teacher guidance. The classical ratio of 1:4:2 should not be attempted without months of preparation.

Best Time to Practice Anulom Vilom

The yogic tradition recommends practicing pranayama during Brahma Muhurta, the auspicious period approximately 90 minutes before sunrise (around 4:30 to 5:30 AM). During this time, the atmosphere is saturated with prana, the mind is naturally quiet, and distractions are minimal. An early morning practice of anulom vilom sets a foundation of calm and clarity that carries through the entire day.

The second-best time is evening, approximately 30 minutes before sunset. Evening practice is especially beneficial for releasing the accumulated stress and tension of the day and preparing the mind and body for restful sleep.

Before meditation: Anulom vilom is one of the best pranayama techniques to practice immediately before seated meditation. The balanced, calm state it creates in the nervous system makes it significantly easier to settle into stillness and concentration. Many experienced meditators consider 5 to 10 minutes of anulom vilom an essential preparatory step for their meditation sessions.

Always practice on an empty stomach — wait at least 2 to 3 hours after a heavy meal and 1 hour after a light snack. Find a clean, quiet, well-ventilated space. Avoid practicing in direct sunlight, strong wind, or near pollution.

Frequently Asked Questions About Anulom Vilom

What is the difference between anulom vilom and nadi shodhana?

Anulom vilom and nadi shodhana are closely related but technically distinct practices. Anulom vilom is alternate nostril breathing without any breath retention (kumbhaka) — you simply alternate the inhalation and exhalation between nostrils in a continuous, flowing pattern. Nadi shodhana includes breath retention: you inhale through one nostril, hold the breath (antara kumbhaka), then exhale through the other nostril, and may also include external retention (bahya kumbhaka). Many modern yoga teachers use the terms interchangeably, but traditionally, anulom vilom is the preparatory practice and nadi shodhana is the more advanced version with retention.

How long should I practice anulom vilom each day?

Beginners should start with 5 minutes of anulom vilom per session (approximately 8 to 10 rounds) and gradually increase over weeks. Intermediate practitioners can practice for 10 to 15 minutes, and advanced practitioners may practice for 20 to 30 minutes or more. The ideal duration also depends on the ratio used: beginners use equal breathing (1:1 for inhale and exhale), while advanced practitioners work with 1:2 or even 1:4 ratios, which naturally extend the practice time per round. Consistency is more important than duration — practicing 10 minutes daily will produce better results than 30 minutes once a week.

Can anulom vilom help with anxiety and high blood pressure?

Yes, anulom vilom is one of the most effective pranayama techniques for reducing anxiety and supporting healthy blood pressure. The slow, rhythmic alternation of breath between nostrils activates the parasympathetic nervous system and reduces cortisol (the stress hormone). Multiple clinical studies have shown that regular practice of alternate nostril breathing significantly reduces both systolic and diastolic blood pressure. A 2019 study in the Journal of Ayurveda and Integrative Medicine found that 30 days of regular anulom vilom practice produced a statistically significant reduction in anxiety scores and blood pressure in participants.

What is the best breathing ratio for anulom vilom?

Beginners should use a 1:1 ratio (equal duration for inhalation and exhalation), typically counting to 4 for each. As comfort and capacity develop, gradually transition to a 1:2 ratio (inhale for 4 counts, exhale for 8 counts). Advanced practitioners may work with 1:2:2 ratios that include retention (inhale 4, hold 8, exhale 8). The classical ratio described in texts like the Hatha Yoga Pradipika is 1:4:2 (inhale 4, hold 16, exhale 8), but this should only be attempted under the direct guidance of an experienced teacher after months of preparation.

When is the best time to practice anulom vilom?

The ideal time for anulom vilom is early morning, ideally during Brahma Muhurta (approximately 4:30 to 5:30 AM), when the air is freshest and the mind is naturally calm. The second-best time is evening, around sunset. Anulom vilom is an excellent practice to perform immediately before meditation, as it balances the nervous system and calms the mind. Always practice on an empty stomach — wait at least 2 to 3 hours after a full meal. If practicing twice daily, morning and evening sessions are ideal.
