Postural Practice Pointer 21 – Backbends disturb the exhale
Backbends disturb the length and quality of the exhale,
in that they impact the Apāna and push the Mūla downwards.
Thus we need to consider an appropriate Pratikriyā Āsana
to compensate for this disturbance to the Apāna Sthāna.
Hence Pratikriyā such as Apānāsana to restore the Apāna.
