Reverse breathing

From Wikipedia, the free encyclopedia

Reversal Breathing is a technique, associated with yoga and chi gong, by expanding the abdomen while breathing out through the nose, and then compressing it while inhaling via the mouth -- the opposite of what an abdomen would do during natural, instinctive breathing. Via this process there can be paid especially close attention to that act of breathing. A pure, inner type of thought focus may thus be given rise.

The importance of inhaling or exhaling through a specific opening as stated is unknown.
