Your Favorite Song Might Just Be Your Pain’s Worst Enemy

Summary: Researchers discovered that music, specifically individuals’ favorite tracks, can reduce pain perception.

In the study, participants felt less pain intensity and unpleasantness when listening to their favorite music compared to unfamiliar relaxing tunes or silence. The emotional themes of the music also played a pivotal role, with “moving or bittersweet” songs proving the most effective.

These findings open up potential drug-free avenues for pain management.

Key Facts:

  1. Participants’ favorite music significantly reduced acute thermal pain perception compared to unfamiliar relaxing music or silence.
  2. Music’s emotional themes influence its ability to dampen pain, with moving or bittersweet tunes being particularly effective.
  3. “Musical chills” — tingling sensations or goosebumps while listening — indicate a process that might block pain signals.

Research has shown that music might be a drug-free way to lower humans’ pain perception. This decreased sensitivity to pain – also known as hypoalgesia – can occur when pain stimuli are disrupted between their point of input and where they are recognized as pain by the conscious mind.

In a new study, researchers in Canada have examined what type of music helps to dampen pain perception.

“In our study, we show that favorite music chosen by study participants has a much larger effect on acute thermal pain reduction than unfamiliar relaxing music” said Darius Valevicius, a doctoral student at the Université de Montréal.

The research was carried out at the Roy Pain Lab at McGill University and published in Frontiers in Pain Research.

“We also found that emotional responses play a very strong role in predicting whether music will have an effect on pain.”

Everybody hurts (but less so when listening to favorite music)

To test which kind of music was most effective for reducing pain, participants received moderately painful thermal stimuli to the inner forearm, resulting in a sensation similar to a hot teacup being held against the skin. These stimuli were paired with music excerpts, each lasting approximately seven minutes.

Compared to control tracks or silence, listening to their favorite music strongly reduced pain intensity and unpleasantness in participants. Unfamiliar relaxing tracks did not have the same effect.

“In addition, we used scrambled music, which mimics music in every way except its meaningful structure, and can therefore conclude that it is probably not just distraction or the presence of a sound stimulus that is causing the hypoalgesia,” Valevicius explained.

The researchers also examined if musical themes could modulate the pain-decreasing effects of favorite music. To do that, they interviewed participants about their emotional responses to their favorite music and assigned themes: energizing/activating, happy/cheerful, calming/relaxing, and moving/bittersweet.

They discovered that different emotional themes differed in their ability to reduce pain.

“We found that reports of moving or bittersweet emotional experiences seem to result in lower ratings of pain unpleasantness, which was driven by more intense enjoyment of the music and more musical chills,” Valevicius said.

Although it is not yet entirely understood what musical chills are, they seem to indicate a neurophysiological process that is effective at blocking pain signals. In some people, chills can manifest as a tingling sensation, shivers, or goosebumps.

Something for the pain

The researchers also pointed to limitations of their study, one of which is concerned with how long participants listen to music samples. For example, listening to relaxing music for longer might have stronger effects than the shorter tracks the participants listened to in this study.

Questions which also need to be addressed in further research include if listening to favorite music is also effective with other, non-thermal pain stimuli, such as mechanical stimulation or chronic pain, the researchers said.

“Especially when it comes to the emotion themes in favorite music like moving/bittersweet, we are exploring new dimensions of the psychology of music listening that have not been well-studied, especially in the context of pain relief. As a result, the data we have available is limited, although the preliminary results are fairly strong,” Valevicius concluded.

Emotional responses to favorite and relaxing music predict music-induced hypoalgesia” by Darius Valevicius et al. Frontiers in Pain Research


Emotional responses to favorite and relaxing music predict music-induced hypoalgesia

Introduction: The hypoalgesic effect of music has long been established. However, the characteristics of music which are important for reducing pain have not been well-studied. Some research has compared subject-selected preferred music to unfamiliar music selected by researchers, and has typically found a superior effect from preferred music. In this study, we sought to discover what aspects of listeners’ relationship with their preferred music was important in producing a hypoalgesic effect.

Methods: We conducted a thermal pain and music listening experiment with 63 participants (14 male, 49 female, mean age = 21.3), in which music excerpts were paired with thermal stimulations. Pain ratings of intensity and unpleasantness, as well as emotional response variables, were rated on visual analog scales. We also conducted brief structured interviews about participants’ favorite music, on which we conducted thematic content analysis. Themes and emotion variables were analyzed for their effects on pain ratings.

Results: We first replicated the finding that favorite music outperforms experimenter-selected relaxing music in reducing pain unpleasantness (MD = −7.25, p < 0.001) and that the difference in hypoalgesia was partially mediated by an increase in musical chills (ab = −2.83, p < 0.01). We then conducted a theme analysis on the interview transcripts and produced four themes relating to emotional experience: moving/bittersweet, calming/relaxing, happy/cheerful, and energizing/activating. We found suggestive evidence that moving/bittersweet favorite music reduces pain unpleasantness through increased music pleasantness (ab = −5.48, p < 0.001) and more musical chills (ab = −0.57, p = 0.004).

Discussion: We find that music pleasantness and musical chills are salient predictors of music-induced hypoalgesia, and that different categories of favorite music derived from qualitative analysis may engage these emotional pathways to different degrees.
