Music really does lower blood pressure

“Music is a fundamental attribute of the human species. Virtually all cultures, from the most primitive to the most advanced, make music. It’s been true through history, and it’s true throughout an individual’s lifespan. In tune or not, we humans sing and hum; in time or not, we clap and sway; in step or not, we dance and bounce.”

“A study from New York examined how music affects surgical patients. Forty cataract patients with an average age of 74 volunteered for the trial. Half were randomly assigned to receive ordinary care; the others got the same care but also listened to music of their choice through headphones before, during, and immediately after the operations. Before surgery, the patients in both groups had similar blood pressures; a week before the operations, the average was 129/82 millimeters of mercury (mm Hg). The average blood pressure in both groups rose to 159/92 just before surgery, and in both groups, the average heart rate jumped by 17 beats per minute. But the patients surrounded by silence remained hypertensive throughout the operation, while the pressures of those who listened to music came down rapidly and stayed down into the recovery room, where the average reduction was an impressive 35 mm Hg systolic (the top number) and 24 mm Hg diastolic (the bottom number).

The listeners also reported that they felt calmer and better during the operation. The ophthalmologic surgeons had no problems communicating with their patients over the sound of the music, but the researchers didn’t ask the doctors if their patients’ improved blood pressure readings made them more relaxed as they did their work. Earlier research, though, found that surgeons showed fewer signs of stress and demonstrated improved performance while listening to self-selected music.”
