Nadi Shodhana is rightly considered one of the best-known and most widely practiced pranayama techniques. Nadi Shodhana breathing is commonly taught in both group and individual yoga classes, and many yoga teachers and spiritual mentors recommend incorporating this practice into a regular routine. But how beneficial is this pranayama, and what can regular practice offer? Are there any fundamental differences in the technique for men and women? We address these and other questions in this article.
Yoga has always been and remains a holistic system for the physical and spiritual development of a person. It is comprehensive in nature and includes physical practices such as asanas, as well as various kriyas, shatkarmas, and pranayamas. These practices do not always work directly with the physical body; in some cases, their effects are understood within a broader framework of mental, energetic, and spiritual development.
A special place in the yogic tradition is occupied by pranayama — practices involving the conscious regulation of the breath and, in the traditional yogic understanding, the cultivation and regulation of prana, or vital energy. Patanjali places pranayama among the eight limbs of classical yoga, between asana and pratyahara. For a broader overview, see The Eight Limbs of Yoga According to Patanjali’s Sutras.
Fr om a superficial perspective, pranayama practices are often regarded simply as breathing exercises. Traditional yoga, however, gives them a broader significance. According to yogic teachings, prana moves through subtle pathways known as nadis.
Different traditional sources give different numbers of nadis. For example, the Prashna Upanishad states that there are 101 channels in the human body; the Hatha Yoga Pradipika mentions 72,000; the Shiva Samhita gives the number as 350,000; while the Katha Upanishad, like the Prashna Upanishad, refers to 101 channels.
At the same time, traditional sources emphasize three particularly important nadis: ida, pingala, and sushumna. According to traditional yogic teachings, chakras are associated with points wh ere these subtle channels intersect. As prana is said to ascend through the chakras toward the crown of the head, it is traditionally associated with the possibility of attaining moksha, or liberation.
The Sanskrit term shodhana means “purification” or “cleansing.” Thus, Nadi Shodhana can traditionally be understood as a practice of purification of the nadis.
From an Ayurvedic perspective, the concept of prana also has an important place in the understanding of vitality and subtle aspects of the doshas. The article Prana, Tejas, and Ojas: The Three Subtle Essences of Ayurveda explores this concept in greater detail.
Let us now examine the technique of Nadi Shodhana pranayama and the effects traditionally associated with its regular practice.
Let us turn to the classical yogic text Hatha Yoga Pradipika. In verses 7–9, the practice is described as follows: the practitioner sits in Padmasana, inhales through the left nostril, retains the breath for as long as possible, and exhales through the right nostril. The practitioner then inhales through the right nostril, performs kumbhaka, and exhales through the left nostril. The practice is performed slowly and without strain.
This description refers to a traditional form of the practice intended for more experienced practitioners. Here, however, we will consider a simpler version suitable for beginners. For this purpose, we can refer to the work of Swami Satyananda Saraswati, A Systematic Course in the Ancient Tantric Techniques of Yoga and Kriya, published in three volumes.
To begin, assume a stable and comfortable seated position, or asana. For beginners, the author recommends starting with Sukhasana or Vajrasana. Since the practice may take some time, the position should be steady and comfortable. There is no need to force yourself into Padmasana simply for the sake of appearance if it causes pain or discomfort.
Next, form Nasikagra Mudra with the fingers. Hold the forearm vertically in front of the chest. Place the index and middle fingers between the eyebrows, the thumb near the right nostril, and the ring finger near the left nostril. Keep the little finger relaxed; it is not involved in the practice.
Close the right nostril and take a smooth, gentle inhalation through the left nostril. Then close the left nostril, open the right nostril, and exhale through the right. Immediately inhale through the right nostril and exhale through the left. This constitutes one complete cycle.
Satyananda Saraswati recommended that beginners practice no more than 15 rounds.
As you become accustomed to the practice and develop greater control over your breathing, gradually work toward making the inhalation and exhalation equal in duration. You can count silently to help maintain a steady rhythm.
Once this has been established comfortably, breath retention (kumbhaka) can be introduced. However, this is a more advanced stage and should not be learned independently. It is best practiced under the guidance of a qualified and experienced teacher.
B.K.S. Iyengar recommends a similar technique in his work Light on Pranayama. One difference is that he recommends a short breath retention of one to two seconds between inhalation and exhalation, with both nostrils closed.
Iyengar also recommends practicing pranayama for 10–15 minutes, focusing not on counting the cycles but simply on the breath. After pranayama, he recommends practicing Shavasana.
Once the basic technique has been understood, we can consider the effects traditionally associated with Nadi Shodhana.
According to B.K.S. Iyengar, regular practice of this technique is traditionally associated with a sense of well-being, greater calmness, and improved concentration. The mind of the practitioner becomes more focused and one-pointed.
Traditional yoga sources also associate Nadi Shodhana with the purification of the nadis and the balancing of the flow of prana. From the perspective of traditional Ayurveda and yoga, breath regulation is considered one of the practices that can influence the movement and cultivation of prana.
Satyananda described Nadi Shodhana as a powerful practice associated with the awakening of Shakti. Within this traditional framework, the practice may support deeper states of meditation and spiritual awareness. Saraswati also stated that this form of pranayama can be practiced as a complete practice in its own right.
The morning is traditionally considered a suitable time for practice. It is recommended to practice in a well-ventilated room on an empty stomach. Ideally, the last meal should have been consumed at least 2–4 hours before practice.
Nadi Shodhana may also be incorporated into an individualized yoga routine according to a person's constitution and needs. Ayurveda and yoga traditions pay particular attention to individual balance and lifestyle. For example, you can explore the articles Yoga for Vata Dosha and Yoga for Pitta Dosha for a broader discussion of yoga practices in relation to the doshas.
It is important to note that the basic technique of Nadi Shodhana does not fundamentally differ for men and women. During pregnancy, however, any pranayama practice should be undertaken only after consultation with a qualified healthcare professional and, preferably, an experienced prenatal yoga teacher.
Despite its apparent simplicity, pranayama requires attention and should be approached responsibly.
People with serious respiratory or cardiovascular conditions should consult a qualified healthcare professional before practicing Nadi Shodhana. The same applies to people with significant blood-pressure disorders, a history of fainting, frequent dizziness, or other serious health conditions.
If you experience dizziness, discomfort, shortness of breath, or any other unusual symptoms during the practice, stop immediately and return to normal breathing.
People with significant psychiatric or neurological conditions should also seek appropriate professional guidance before beginning pranayama, particularly practices involving breath retention.
Advanced forms of Nadi Shodhana involving prolonged kumbhaka should not be attempted without proper instruction. Breath retention can significantly change the physiological demands of the practice and therefore requires gradual and competent supervision.
Remember that success in this, as in any other yogic practice, is based on consistency. Practice regularly and do not become discouraged by initial difficulties. We have deliberately not described more advanced techniques here, as they should be learned under the guidance of a qualified teacher.
Start with the basics and progress gradually, step by step. Pranayama is not simply a set of breathing exercises; within the traditional yoga system, it is a significant discipline involving conscious regulation of the breath and attention.
B.K.S. Iyengar recalled that even after six years of intensive asana practice, his teacher Krishnamacharya was still reluctant to teach him pranayama. Today, however, we have an opportunity to study and practice these traditional techniques with greater access to qualified instruction and educational resources.
1. What is Nadi Shodhana Pranayama?
Nadi Shodhana is a traditional yogic breathing practice involving alternate-nostril breathing. The Sanskrit term Nadi Shodhana is commonly translated as “purification of the nadis,” or subtle energy channels.
2. How do you practice Nadi Shodhana?
Sit comfortably with the spine upright. Close the right nostril and inhale through the left. Close the left nostril, exhale through the right, then inhale through the right and exhale through the left. This completes one round. Beginners should practice gently without forcing the breath.
3. How many rounds of Nadi Shodhana should beginners practice?
Satyananda Saraswati recommended that beginners practice no more than 15 rounds. It is generally better to begin with fewer comfortable rounds and gradually increase the duration as the practice becomes familiar.
4. Should you hold your breath during Nadi Shodhana?
Beginners do not need to hold the breath. Breath retention, or kumbhaka, is an advanced aspect of pranayama and is best learned gradually under the guidance of an experienced teacher.
5. What are the traditional benefits of Nadi Shodhana?
Traditional yoga sources associate Nadi Shodhana with greater calmness, concentration, mental clarity, and the balancing of prana. In the traditional yogic framework, it is also regarded as a practice for purifying the nadis and supporting meditation.
6. When is the best time to practice Nadi Shodhana?
Nadi Shodhana is traditionally practiced in the morning, in a quiet and well-ventilated space. It is generally recommended to practice on an empty stomach, ideally at least 2–4 hours after a meal.
7. Can Nadi Shodhana be practiced by women?
Yes. The basic technique does not fundamentally differ for men and women. During pregnancy, however, pranayama should be practiced only after consultation with a qualified healthcare professional and an appropriately trained teacher.
8. Who should avoid Nadi Shodhana?
People with serious respiratory or cardiovascular conditions, significant blood-pressure disorders, frequent dizziness, a history of fainting, or other serious health conditions should consult a qualified healthcare professional before practicing. Advanced breath retention requires additional caution.
9. What should I do if I feel dizzy during Nadi Shodhana?
Stop the practice immediately and return to normal breathing. If dizziness occurs repeatedly, discontinue the practice and consult a qualified healthcare professional before trying pranayama again.
10. Is Nadi Shodhana simply a breathing exercise?
Within the traditional yoga system, Nadi Shodhana is considered more than a simple breathing exercise. Pranayama involves conscious regulation of the breath and attention and has an important place in the classical eight-limbed path of yoga.
