Abstract:
Much research has focused on the efficacy of biofeedback therapy; however, previous studies only compared biofeedback treatment with no-treatment conditions or pre- and posttest data. Examination of biofeedback relaxation therapy with a false-feedback condition could produce data on physiological changes suitable to clarify findings. 63 participants were randomly assigned to either an accurate- or false-feedback condition for a 5-min. period. Analysis of the measures yielded significant differences in both groups between pre- and posttests, but not between groups, suggesting a potential placebo effect of biofeedback-induced relaxation.

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the risk...
