Most people already use music as a tool without thinking about it. A playlist for the run, something soft for the drive home, a loud album to get through the dishes. The research on these everyday uses is better than you might expect for some of them, like exercise and pain, and thinner for others. Here is what holds up, use by use, along with a couple of popular claims that don't.
If you want the brain science behind why music feels rewarding at all, we cover that separately in how music affects your brain. This article is about practical results.
Exercise: hard work feels easier
This is one of the best-studied uses of music. In 2020, Peter Terry, Costas Karageorghis and colleagues published a meta-analysis in Psychological Bulletin covering 139 studies and about 3,600 participants. Music during exercise had a moderate positive effect on how people felt, a smaller but real effect on physical performance, and lowered how hard the effort felt. It also slightly improved oxygen efficiency. It did not meaningfully change heart rate, so music doesn't make your body work less. It makes the same work feel more manageable.

The practical version is simple. For steady cardio, pick music with a clear beat you can move to, and let your stride or cadence fall in with it. For a warm-up or a hard interval, louder and faster tends to work better than calm background music.
Pain and medical stress
The strongest evidence for music in a medical setting comes from surgery. In 2015, Jenny Hole, Martin Hirsch, Elizabeth Ball and Catherine Meads of Queen Mary University of London published a systematic review in The Lancet of 73 randomized trials. Patients who listened to music before, during or after an operation reported less pain and less anxiety afterward, used less pain medication and were more satisfied with their care. Music helped even when patients were under general anesthesia, and it made little difference which music was used or exactly when it was played. It did not shorten hospital stays.
Two caveats matter. The trials varied a lot in design, and music was always an addition to normal care, never a replacement for pain relief. Still, it is cheap, safe and easy to add. The same logic applies to smaller ordeals like a dental appointment or a blood test: your own calm music is a reasonable thing to bring.
Mood: match it first, then shift it
People often assume that the right music for a bad mood is cheerful music. Research suggests something more subtle. In a 2015 study in Frontiers in Human Neuroscience, Leah Sharman and Genevieve Dingle of the University of Queensland put 39 fans of extreme metal through an anger-inducing task, then gave them ten minutes of their own playlist or ten minutes of silence. Hostility, irritability and stress fell in both groups, so the music didn't make anyone angrier, and the metal listeners also reported feeling more inspired afterward. The authors suggest that intense music can match a listener's existing arousal and help them work through the feeling rather than suppress it.
For clinical depression, the relevant evidence is about music therapy with a trained therapist, not playlists. A 2017 Cochrane review by Sonja Aalbers and colleagues found that adding music therapy to standard treatment probably reduces depressive symptoms in the short term, based on nine small studies. That is encouraging but limited, and it is not a reason to replace any existing treatment. The psychology of why we use music to manage feelings in the first place is covered in why we listen to music.
Sleep
Music at bedtime has a modest but real evidence base. A 2022 Cochrane review led by Kira Jespersen of Aarhus University pooled 13 trials with about 1,000 adults with insomnia. Listening to calm music probably improved self-reported sleep quality, by about 2.8 points on a standard 21-point questionnaire. The authors could not say whether it changed how severe the insomnia was or how fast people fell asleep, and most trials relied on self-reports, which can overstate benefits.

If you want to try it, choose slow, quiet music you already know, so there is nothing to follow, and set a timer so it doesn't run all night. Many people find that a steady, non-musical sound works even better once the lights are off, because there is no melody to track at all. Rain, ocean waves and pink noise are common choices. Our guide to what actually works for sleep puts sound in context with light, temperature and schedule.
A tempo that can save a life
The American Heart Association recommends chest compressions at 100 to 120 per minute during CPR, and it suggests pacing them to a song in that range, such as "Stayin' Alive," which runs at roughly 103 beats per minute. In a small 2008 test at the University of Illinois College of Medicine at Peoria, David Matlock had 15 doctors and medical students practice on mannequins while listening to the song. They averaged about 109 compressions a minute, and about 113 when they repeated the drill five weeks later while only thinking of the song. The study was tiny and used people who already knew CPR, but the idea stuck: the Heart Association itself now uses the song as a pacing tip in its Hands-Only CPR materials.
Claims to drop
Two claims appear in many articles about the benefits of music, including an earlier version of this one. The first is that music "boosts immunity." In their 2013 review of the neurochemistry of music in Trends in Cognitive Sciences, Mona Lisa Chanda and Daniel Levitin of McGill University looked at stress, reward, social and immune effects and concluded that this kind of research is still in its infancy. There are small studies on immune markers, but no good evidence that listening to music keeps you from getting sick.
The second is that background music helps you lose weight. We could not find solid evidence for it. Music can make exercise feel easier, as the research above shows, and that may help you stick with a routine. That is as far as the evidence goes.
Using music on purpose
- Workouts: a clear, fast beat you can move with.
- Before a procedure or a stressful appointment: calm music you choose yourself.
- A bad mood: start with music that matches how you feel, then move gradually toward how you want to feel.
- Winding down: slow, familiar music, or a steady sound like a flowing river once you are ready to sleep.
For the moments when you want sound without a song, Noizio mixes 40+ ambient sounds with a sleep timer. It is available for Mac and iOS, and on Android, so you can keep a mix for sleep and another for winding down.
