Ujjayi or The “loud breathing” consists of drawing air in through both nostrils with the glottis held partially closed. This partial closure of the glottis produces a sound like that heard in sobbing, except that it is continuous and unbroken. Ujjayi breathing has many variations. For example, we can breathe in through the throat, then completely close one nostril and breathe out through the other nostril, which is only partly closed. This technique is called an anuloma ujjayi. In a pranayama technique called viloma ujjayi, we breathe in through the nostril and breathe out through the throat. This technique is used to lengthen the inhalation. In ujjayi pranayama it is important to follow this rule: when we regulate the breath through the nostril, we never breathe through the throat at the same time.
