From Dennis Lewis, the full skinny on breathing:

Deep, natural breathing can be important for health, healing, and spiritual well-being. Such breathing can increase our vitality and promote deep relaxation. Unfortunately, many of us who try to take a deep breath sometimes do the exact opposite of what is required: we suck in our bellies, raise our shoulders, and try to expand our chest. That is shallow breathing.

If we are sitting quietly reading, for example, we do not need to be breathing deeply. If we are working hard and expending a great deal of energy, however, we might well need to breathe deeply. Another situation in which deep breathing can be beneficial is when we are trying to revitalize our energy or for special breathing or healing exercises.
