Mind-body connections in mental health

Do you think that the physical expression of anger is cathartic, or is a merely an distraction technique? Does the physical aggression and expression "release" the anger within us or does it simply give us something to do that is engaging and physical. In this physical act, perhaps we are increasing our heart rates and, in a sense, exercising our anger away? I wonder?

In dealing with trauma, I have always wondered how mind-body work like meditation, mindfulness and even exercise may help. It was interesting to hear that for some monks, the quiet of meditation actually increased the frequency of feelings of anxiety related to past trauma. This psychiatrist seems like an incredibly intelligent and sensitive man and seems to offer some wonderfully alternative treatment methods to help monks regain a sense of calm and connectedness through meditation.
