Left-Nostril Breathing (Chandra Bhedana) is breathing in through the left nostril and out through the right. In yoga tradition, the left nostril is the calming side, often practised in the evening. Research on it is still early.
How do you do Left-Nostril Breathing?
- Your right thumb closes the right nostril; your ring finger closes the left.
- Breathe in through your left nostril.
- Switch, and breathe out slowly through your right.
