This breathing practice is perfect for doing after your regular yoga practice, after savasana, to set you up for a nice meditation/concentration practice.

You could also try this before bed if you are having troubles falling asleep and feel like your mind is buzzing. Alternate nostril breathing helps to balance your energy so you feel more calm, centred & relaxed.

There are different types of Nadi Shodhana, this is the one that is taught in Ashtanga. It's done in the last 3 postures of closing sequences: after Yoga Mudra/Padmasana and before Utpluthih (lifting up in crossed legs or lotus).

Have you tried this one? Or prefer a different method? You can also add breath retentions for a few seconds on inhale or exhale if you feel like you are ready to add in more to your breathing practice (only add if you don't feel panicked or anxious though, be patient!)
