Breathing Technique for Anxiety

Place the right hand in the air with the forefinger and middle finger bent towards the palm; thumb, ring, and pinkie fingers in the air. Close off the right nostril with the thumb and inhale into the left nostril; then close the left nostril with the ring and pinkie fingers and open the right nostril and exhale through it; then inhale into the right nostril and then close the right nostril and open the left and exhale through it. Do this for 5-20 rounds.
