In Saturday’s Associated Press, Christina Larson writes, “Nurse Rod Salaysay works with all kinds of instruments in the hospital: a thermometer, a stethoscope and sometimes his guitar and ukulele. In the recovery unit of UC San Diego Health, Salaysay helps patients manage pain after surgery. Along with medications, he offers tunes on request and sometimes sings. His repertoire ranges from folk songs in English and Spanish to Minuet in G Major and movie favorites … Salaysay sees changes in their vital signs like lower heart rate and blood pressure, and some may request fewer painkillers…. Over the past two decades, live performances and recorded music have flowed into hospitals and doctors’ offices as research grows on how songs can help ease pain. The healing power of song may sound intuitive given music’s deep roots in human culture. But the science of whether and how music dulls acute and chronic pain—technically called music-induced analgesia—is just catching up. No one suggests that a catchy song can fully eliminate serious pain. But several recent studies, including in the journals Pain and Scientific Reports, have suggested that listening to music can either reduce the perception of pain or enhance a person’s ability to tolerate it….It’s a simple prescription with no side effects, some doctors now say.”
