Nadi shuddhi pranayama: Gently cleansing the energy channels

What is nadi shuddhi pranayama or anulom vilom ?

Nadi shuddhi pranayama (nadi shodhan pranayama) is a basic and most widely used form of pranayama and means nadi = energy channel + shuddhi = cleanser. Anulom vilom, which means inhalation-exhalation, is another name for this yogic breathing exercise.

How to do nadi shuddhi pranayama easily?

  • First, sit comfortably in padmasana, sukhasana or vajrasana. Also, keep the back erect.
  • Next, place thumb over right nostril and ring finger + little finger over left nostril. Then, turn the other 2 fingers turned into the palm.
  • Lastly, close the right nostril with your thumb and inhale through the left nostril for 4 counts.
  • Thereafter, close both nostrils and hold your breath for 6 counts.
  • Now, release the ring finger from over the left nostril & exhale through the left nostril for 6 counts, increasing to 8 counts as your capability increases.
  • Again, close both nostrils & hold your breath for 6 counts.
  • After this, repeat using the reverse method.
  • Breathe in through the right nostril for 4 counts, close both nostrils for 6 counts, open the left nostril, and breathe out for 6 counts.
  • This is a round of nadi shuddhi pranayama.
  • Importantly, repeat the cycle 5 times. Rest between cycles if required.
  • Additionally, try to slowly increase to 20 rounds.
  • Lastly, slowly try increasing the duration of inhalation (puraka), holding (kumbhaka), and exhalation (rechaka) as you gain confidence.

Over time, you could also increase the ratio of inhalation, holding, and exhalation to your comfort. Only, ensure that exhalation is close to twice of inhalation so that lung volumetric efficiency is increased. Also, ensure that the breathing is calm and steady, not erratic, agitated, or jerky.

What are the benefits of nadi shuddhi pranayama ?

  • Since the breathing process is measured and steady, the forced volume capacity of the lung increases over time and with practice.
  • Consequently, the evacuation of waste gases (CO2 and water vapour) is increased.
  • As a result, the transfer capacity of the lungs gets improved. Importantly, transfer capacity is the amount of oxygen that enters the body and the amount of CO2 + water vapour that gets removed from the body.
  • Furthermore, the above practice increases oxygen content in the bloodstream while removing toxins. This helps improve health and immunity.
  • Nadi shuddhi pranayama also improves left/ right brain activity equalization.
  • Lastly, the practice of steady breathing reduces stress, and purges excess adrenalin and related toxins from the system.

Let us learn about the variants of nadi shuddhi pranayama.

The surya-bheda (splitting the sun) variant of nadi shuddhi pranayama

This is a variation of nadi shuddhi pranayama. In nadi shuddhi, the inhalation and exhalation are alternated between the left and right nostrils. However, in surya bheda pranayama, all inhalation is only performed using the right nostril, while the exhalation is performed using the left nostril.

Surya-bheda technique explained in easy steps:

  • First, sit comfortably in padmasana, sukhasana or vajrasana. Keep your back erect.
  • Next, close the left nostril with your thumb and inhale through the right nostril for 4 counts.
  • After this, close both nostrils and hold your breath for 6 counts.
  • Release the ring finger from over the left nostril & exhale to 6 counts, increasing to 8 counts as you become confident.
  • Finally, close both nostrils & hold your breath for 4 counts.
  • Lastly, breathe normally, and relax.
  • This is a round of surya-bheda-pranayama which activates pingala-nadi.
  • Repeat by starting again with inhalation through the right nostril, hold, exhalation through the left nostril, hold.
  • Additionally, practice 5 rounds.
  • Lastly, rest in between if required.

The chandra bheda (splitting the moon) variant of nadi-shuddhi pranayama

In nadi-shuddhi, the inhalation and exhalation are alternated between the left and right nostrils. However, in chandra-bheda pranayama, all the inhalation is only performed using the left nostril while the exhalation is performed using the right nostril. This process is the opposite of surya-bheda-pranayama.

Chandra bheda pranayama technique explained in easy steps:

  • First, sit comfortably in padmasana, sukhasana or vajrasana. Keep your back erect.
  • Next, close the right nostril with your thumb and inhale through the left nostril for 4 counts.
  • After this, close both nostrils for 4 counts & hold your breath.
  • Closing ring finger from over left nostril & exhale through the right nostril to 6 counts, increasing to 8 counts as you become confident.
  • Finally, close both the nostrils & hold your breath for 6 counts.
  • Lastly, breathe normally, and relax.
  • This is a round of chandra-bheda-pranayama activates the ida-nadi.
  • Repeat by starting again with inhalation through the left nostril, hold, exhalation through the right nostril, hold.
  • Additionally, practice 5 rounds.
  • Lastly, rest in between if required.

After a round of surya-bheda and chandra-bheda-pranayama, perform nadi-shuddhi to re-balance the flow of prana in the body.

The Hatha Yoga Pradeepika on nadi-shuddhi: Chapter 2, verses 7 to 10.

  • Sitting in padmasana, the yogi inhales through the Moon nostril (ida or left nostril). Then, retaining it to one’s ability, he exhales through the Sun (pingala or right nostril).
  • Then, drawing in air through the Sun nostril (right nostril), the belly should be filled. After performing kumbhaka as before, the air should be exhaled through the ida.
  • Inhaling thus, through the same nostril through which air was expelled, and having retained it to the utmost, it should be exhaled through the other, slowly, not fast.
  • If one inhales the air through the ida, it should be expelled through the pingala. If air is drawn in through the pingala and retained there, it should be expelled through the ida.
  • Those that practice thus through the Sun and Moon should have clean nadis after 3 months or so.
