Looking for a creative way to quicken your recovery from surgery? The key may be found in listening to music, according to research presented at the American College of Surgeons (ACS) Clinical Congress 2024 in San Fransisco, California.
Researchers at California Northstate University College of Medicine in Elk Grove, California analyzed existing studies on music and its role in helping people recover from surgery, narrowing a list of 3,736 studies to 35 research papers. All of the studies included data on patient outcomes, such as pain and anxiety, as well as measures of heart rate and opioid use. In their analysis, the researchers found that the simple act of listening to music after surgery, whether with headphones or through a speaker, had noticeable effects on patients during their recovery period:
-
Reduced anxiety levels: Across all the analyzed studies, patient self-reported anxiety levels were reduced by about 2.5 points, or 3%, as assessed by the State-Trait Anxiety Inventory, a patient-answered survey that assesses anxiety on a scale of 80.
-
Lower heart rate: Patients who listened to music experienced a reduced heart rate (around 4.5 fewer beats per minute) compared with patients who did not listen to music, which the authors noted is significant because keeping a patient's heart rate within a healthy range helps improve recovery by allowing effective circulation of oxygen and nutrients throughout the body, especially to areas that were operated on. In addition, tachycardia, or a heart rate greater than 100, can lead to abnormal heart rhythms such as atrial fibrillation, which can be life-threatening.
When patients wake up after surgery, sometimes they feel really scared and don't know where they are. Music can help ease the transition from the waking up stage to a return to normalcy and may help reduce stress around that transition."

Dr. Frezza and co-authors noted that unlike some more active therapies such as meditation or Pilates which require considerable concentration or movement, listening to music is a more passive experience and can be incorporated by patients without much cost or effort almost immediately after surgery.
"Although we can't specifically say they're in less pain, the studies revealed that patients perceive they are in less pain, and we think that is just as important," said Shehzaib Raees, first author of the study and a third-year medical student at the California Northstate University College of Medicine. "When listening to music, you can disassociate and relax. In that way, there's not much you have to do or focus on, and you can calm yourself down."
The study authors noted that a reduction in cortisol levels when listening to music may play a role in easing patients' recovery from surgery. Some variables, such as how long the patients listened to music, could not be controlled for in the analysis. Future research will look at a pilot program to evaluate the use of music in the surgical setting as well as in the intensive care unit.
Dr. Frezza's advice? If you feel up for it after surgery, listen to whatever music you enjoy.
"We're not trying to say that one type of music is better than another," he said. "We think music can help people in different ways after surgery because music can be comforting and make you feel like you're in a familiar place."
