Eventually, put it into words

". . . in a recent study, students were randomly assigned either . . .

1. to express a traumatic experience using bodily movement, 
2. to express a traumatic experience first through movement and then in written form, or 
3. to exercise in a prescribed manner for 3 days, 10 minutes per day (Krantz & Pennebaker, 1996).  

Whereas participants in the two movement-expression groups reported that they felt happier and mentally healthier in the months after the study, only the movement-plus-writing group showed significant improvements in physical health and grade point average. 

The mere expression of trauma is not sufficient.  Health gains appear to require translating experiences into language."
