In this breathing technique, we inhale through the left nostril and exhale through the right nostril.
Practise for ten rounds, and you will feel the calming effect of Chandra Bhedana. If you are new to breathwork, you can keep the duration of inhalation and exhalation equal. As your practice improves, extending the exhalations twice as long as the inhalations will increase the technique's effectiveness. As you progress, you can also add a breath-hold by closing both nostrils after you inhale. Chandra Bhedana is a single nostril pranayama technique, just like Surya Bhedana. These two techniques have opposite effects and should not be practised on the same day.
