Thirty-two depressed adolescent mothers received ten 30-minute sessions of massage therapy or relaxation therapy over a five-week period. Subjects were randomly assigned to each group. Although both groups reported lower anxiety following their first and last therapy sessions, only the massage therapy group showed behavioral and stress hormone changes including a decrease in anxious behavior, pulse, and salivary cortisol levels. A decrease in urine cortisol levels suggested lower stress following the five-week period for the massage therapy group.
