Take a deep cleansing breath

Take a deep cleansing breath
 

How to say

"Take a deep cleansing breath"


it means more than just breathe deeply such as respire profundo.

But I don't find any real good examples.
the kind of breathing to begin meditation or mindfullness.

Gracias
Thanks in advance.

Perhaps this will do:
Tome una respiración profunda y limpiadora.
