According to current medical research, stress is a cause of 98% of all disease. Not only heart attacks, strokes, and immune system breakdowns, but also every disease known (with the exception of two viruses) has been shown to be caused by or exacerbated by stress. Recent biofeedback studies show that drumming for brief periods can alter the brainwave patterns, dramatically reducing stress. Just 15 minutes of drumming along with our own heartbeats can double the alpha brainwaves. So drumming actually meditates us!
