Taking care of my breathing pattern, among other things, is what helped me reduce/eliminate anxiety - especially while programming. I always had some anxiety and social awkardness after working. Taking care of my breathing, posture, being in sync with the breath, this is what helped me eliminate these issues. The mind is more cooled down, detached and objective, whereas previously, the mind was at the whim of whatever thoughts were running through - which was the source of anxiety.
