Dr. Daniel und Bernadette Skubik | A driving drum rhythm in excess
"A driving drum rhythm in excess of three to four beats per second will put the brain into a state of stress, regardless if the listener likes or dislikes the music. And when the brain is in this stressful state, it will release opioids—a group of natural hormones that function like morphine—to help return itself to normal equilibrium and sense of well-being. These natural opioids, if experienced often enough, can be addicting, creating in the listener the continual desire for that ‘high’ somewhat like the high runners experience."
