What Is Alternate Nostril Breathing?
Alternate Nostril Breathing is a foundational practice in yoga, known in Sanskrit as Nadi Shodhana Pranayama. The name translates to "subtle energy clearing breathing technique." The core idea is to purify the body's energy channels (nadis) to allow life
force, or prana, to flow freely. The practice involves consciously breathing through one nostril at a time while gently closing the other with your fingers. This simple act of regulating the breath is believed to balance the left and right hemispheres of the brain, leading to a state of equilibrium and calm. Though there are a few variations, the most common form, often recommended for beginners, focuses on a smooth, continuous flow of breath without any stressful pauses.
The Science of a Quieter Mind
While the promise of a completely quiet mind overnight may be an overstatement, the benefits of Nadi Shodhana are well-documented. The practice has a profound effect on the autonomic nervous system. It helps to activate the parasympathetic nervous system, often called the "rest and digest" system, which slows the heart rate, reduces blood pressure, and tells your body it is safe to relax. Studies have shown that regular practice can lower perceived stress levels and reduce anxiety. By calming the physical symptoms of stress—like a racing heart and quick, shallow breathing—it helps to quiet mental chatter. This makes it an excellent practice before bed, as it can ease the transition into sleep by promoting relaxation and reducing the mental restlessness that often keeps us awake.
A Step-by-Step Guide
Getting started is simple, and you can do it almost anywhere you can sit comfortably. Find a quiet space and sit with your spine straight, either cross-legged on the floor or in a chair with your feet flat. Let your shoulders relax.
1. Prepare your hand: Rest your left hand on your left knee. Bring your right hand up to your nose. A traditional hand position, or mudra, is to fold your index and middle fingers toward your palm, leaving your thumb, ring finger, and little finger extended. You will use your thumb to close your right nostril and your ring finger for the left.
2. Begin the cycle: Close your eyes and take a deep breath in and a long breath out through both nostrils. Now, gently close your right nostril with your thumb.
3. Inhale through the left: Slowly and smoothly inhale through your open left nostril.
4. Switch and exhale: Close your left nostril with your ring finger, then release your thumb to open the right nostril. Exhale slowly and completely through the right nostril.
5. Inhale through the right: Keeping the left nostril closed, inhale slowly through the right nostril.
6. Switch and exhale again: Close your right nostril with your thumb, release your ring finger, and exhale completely through your left nostril.
This completes one full round. Aim to practice for 5 to 10 minutes, especially before sleep. The key is to keep your breath smooth, slow, and quiet—never force it.
Tips for a Deeper Practice
To get the most out of Nadi Shodhana, consistency is more important than duration. Try to practice at the same time each day, such as in the morning to set a calm tone or in the evening to unwind. Always practice on an empty stomach. Make sure your posture is upright but not rigid; a straight spine allows energy to move freely. If you find your mind wandering, gently guide your focus back to the sensation of the breath moving in and out. The goal is not to have zero thoughts, but to not let them carry you away. Over time, you may find your ability to concentrate improves both during and after the practice.
Important Cautions to Consider
Alternate nostril breathing is safe for most people. However, you should avoid it if you have a cold, fever, or blocked sinuses. If you feel dizzy or uncomfortable at any point, stop the practice and return to normal breathing. People with high blood pressure, heart conditions, or respiratory issues like asthma should consult a doctor before starting. It is generally recommended that these individuals practice without any breath retention (holding the breath), which is a more advanced variation of the technique. Pregnant women should also stick to the basic version without breath holds and consult their healthcare provider first.
