The<unk>  is a specific diaphragmatic breathing technique that was developed in the 1960s. The technique emphasises nose breathing and the development of a breathing pattern to suit current activity. It also involves relaxation exercises that, in concert with the breathing technique, have been purported to aid depression and anxiety. Developed at<unk>  Hospital in Cambridgeshire, England, the method seeks to control "over-breathing" (rapid shallow breaths taken at the top of the chest) that are usually associated with persons under stressful conditions. The aim is to encourage gentler, more relaxed breathing, using the abdomen and diaphragm rather than the chest.
