Your body language is a very strong indicator of how you're reacting to your anxiety symptoms.  Since our goal is to learn to be non-reactive and not fuel the fear cycle, its really helpful to be aware of your body language.  Knowing your rituals and tics and physical habits can help you see how you're adding fuel to the fire.  Once you become aware of your anxiety-related body language, you can start the work of extinguishing all these little things so your brain can learn that they've never been needed to keep you safe.
I talk about the use of video as a tool here.  I suggest that everyone video themselves at least a few times during periods of high anxiety and panic, even if nobody ever sees the video but you.  The value as a self-teaching tool is enormous.
