Sit in Easy pose. Hold your hand over your navel, and practice forcefully exhaling out the nose repeatedly. Your belly should be pumping in and out. The force of the exhale will naturally draw in a new breath, so there is no need to inhale consciously. Start slowly and it is important to eventually speed up the pace of this breath in order to stoke the fire of the breath. Practice for 1-2 minutes.
Caution: This is a powerful breathing technique. Stop if you feel dizzy. Not recommended during pregnancy or for those with high blood pressure.
Benefits: Rapidly clears the nasal passages and sinuses. Increases lung capacity and oxygen in the blood. Energizes the body and boosts the immune system.
