What is Ujjayi?During spinal breathing, on the exhalations, allow your epiglottis to close enough so that there is a small restriction of the air leaving your lungs. The epiglottis is the door in your throat that automatically closes your windpipe (trachea) when you hold your breath or swallow. By partially closing it as you exhale, a fine hissing sound will occur in your throat. This is called "ujjayi."
