5 Ways Music Improves Our Health – By Jill Suttie
Music reduces stress and anxiety.
My choice to bring music into the birthing room was probably a good one. Research has shown that listening to music — at least music with a slow tempo and low pitch, without lyrics or loud instrumentation — can calm people down, even during highly stressful or painful events.
Music can prevent anxiety-induced increases in heart rate and systolic blood pressure, and decrease cortisol levels — all biological markers of stress. In one study, researchers found that patients receiving surgery for hernia repair who listened to music after surgery experienced decreased plasma cortisol levels and required significantly less morphine to manage their pain. In another study involving surgery patients, the stress reducing effects of music were more powerful than the effect of an orally-administered anxiolytic drug.
Performing music, versus listening to music, may also have a calming effect. In studies with adult choir singers, singing the same piece of music tended to synch up their breathing and heart rates, producing a group-wide calming effect. In a recent study, 272 premature babies were exposed to different kinds of music — either lullabies sung by parents or instruments played by a music therapist — three times a week while recovering in a neonatal ICU. Though all the musical forms improved the babies’ functioning, the parental singing had the greatest impact and also reduced the stress of the parents who sang.
Though it’s sometimes hard in studies like this to separate out the effects of music versus other factors, like the positive impacts of simple social contact, at least one recent study found that music had a unique contribution to make in reducing anxiety and stress in a children’s hospital, above and beyond social contributions.
Music decreases pain.
Music has a unique ability to help with pain management, as I found in my own experience with giving birth. In a 2013 study, sixty people diagnosed with fibromyalgia — a disease characterized by severe musculoskeletal pain — were randomly assigned to listen to music once a day over a four-week period. In comparison to a control group, the group that listened to music experienced significant pain reduction and fewer depressive symptoms.
In another recent study, patients undergoing spine surgery were instructed to listen to self-selected music on the evening before their surgery and until the second day after their surgery. When measured on pain levels post surgery, the group had significantly less pain than a control group who didn’t listen to music.
It’s not clear why music may reduce pain, though music’s impact on dopamine release may play a role. Of course, stress and pain are also closely linked; so music’s impact on stress reduction may also partly explain the effects.
However, it’s unlikely that music’s impact is due to a simple placebo effect. In a 2014 randomized control trial involving healthy subjects exposed to painful stimuli, researchers failed to find a link between expectation and music’s effects on pain. The researchers concluded that music is a robust analgesic whose properties are not due simply to expectation factors.
Music may improve immune functioning.
Can listening to music actually help prevent disease? Some researchers think so.
Wilkes University researchers looked at how music affects levels of IgA — an important antibody for our immune system’s first line of defense against disease. Undergraduate students had their salivary IgA levels measured before and after 30 minutes of exposure to one of four conditions — listening to a tone click, a radio broadcast, a tape of soothing music or silence. Those students exposed to the soothing music had significantly greater increases in IgA than any of the other conditions, suggesting that exposure to music (and not other sounds) might improve innate immunity.
Another study from Massachusetts General Hospital found that listening to Mozart’s piano sonatas helped relax critically ill patients by lowering stress hormone levels, but the music also decreased blood levels of interleukin-6 — a protein that has been implicated in higher mortality rates, diabetes and heart problems.
According to a 2013 meta-analysis, authors Mona Lisa Chanda and Daniel Levitin concluded that music has the potential to augment immune response systems, but that the findings to date are preliminary. Still, as Levitin notes in one article on the study, “I think the promise of music as medicine is that it’s natural and it’s cheap and it doesn’t have the unwanted side effects that many pharmaceutical products do.”
