". . . in a recent study, students were randomly assigned either . . .Writing about emotional experiences as a therapeutic process
- to express a traumatic experience using bodily movement,
- to express a traumatic experience first through movement and then in written form, or
- 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."
