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 like “Somewhere Over the Rainbow.”
Patients often smile or nod along. Salaysay even sees changes in their vital signs like lower heart rate and blood pressure, and some may request fewer painkillers.
“There’s often a cycle of worry, pain, anxiety in a hospital,” he said, “but you can help break that cycle with music.”
Salaysay is a one-man band, but he’s not alone. 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.
Scientists explore how music affects pain perception
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.
What seems to matter most is that patients — or their families — choose the music selections themselves and listen intently, not just as background noise.
How music can affect pain levels
“Pain is a really complex experience,” said Adam Hanley, a psychologist at Florida State University. “It’s created by a physical sensation, and by our thoughts about that sensation and emotional reaction to it.”
Two people with the same condition or injury may feel vastly different levels of acute or chronic pain. Or the same person might experience pain differently from one day to the next.
Acute pain is felt when pain receptors in a specific part of the body — like a hand touching a hot stove — send signals to the brain, which processes the short-term pain. Chronic pain usually involves long-term structural or other changes to the brain, which heighten overall sensitivity to pain signals. Researchers are still investigating how this occurs.
“Pain is interpreted and translated by the brain,” which may ratchet the signal up or down, said Dr. Gilbert Chandler, a specialist in chronic spinal pain at the Tallahassee Orthopedic Clinic.
Researchers know music can draw attention away from pain, lessening the sensation. But studies also suggest that listening to preferred music helps dull pain more than listening to podcasts.
“Music is a distractor. It draws your focus away from the pain.
