Sometimes I find myself taking in very shallow breaths of air. A while ago I read a book on Yoga from the local library and there was also chapter on breathing. However I didn't really have to time to go into it at great length. But when I was standing at the busstop this morning I was reminded of it, and made a mental note to myself that I needed to look it up online. So I did. You should check it out. Hatha Yoga breathing: Yoga recognizes three separate forms of breathing - diaphragmatic, intercostal, and clavicular. Complete yogic breathing combines all three, and constitutes the ideal technique.
