The Medicine in Your Own Voice

What the Research Actually Shows

Start with the finding that answers the question most directly, because it separates singing from simply having music on. When researchers had the same amateur choir sing on one day and only listen to choral music on another, the two were not equal. Singing raised positive feeling and lifted a marker of immune activity in the saliva; listening did not lift mood in the same way (Kreutz et al., 2004). This is the crucial distinction. The good feeling you get from singing is not the music washing over you — it is something your body does when you are the one making the sound.

The second finding explains where that lift comes from in the body. In a set of studies on music-making, actively performing — singing, drumming, dancing — raised people’s pain threshold, a reliable sign that the body has released endorphins, its own natural opioids. Quiet, passive listening did not produce the same effect (Dunbar et al., 2012). In plain terms: the small wave of ease and even mild euphoria after you have really sung is a genuine neurochemical event. Your body pays you for singing.

The third finding matters because it shows this holds even when there is real reason to feel terrible. Researchers studied people living with the weight of cancer — patients, and those caring for them — and found that a single hour of singing was linked to a significant drop in cortisol, the body’s main stress hormone, along with improved mood and a lift in immune signalling (Fancourt et al., 2016). That is worth holding onto. This is not a trick that only works when life is already light. Singing reached people in some of the hardest circumstances there are — which means it can likely reach you on an ordinary heavy day, too.

What Perukua Says About the Singing Voice

Perukua — the Australian vocalist and women’s facilitator whose sound and voice work has reached women in more than 63 countries — would say the research is measuring something she has spent a lifetime inside. For her the voice is not decoration; it is, in her words, “the bridge between body and soul.” “They say in the beginning was the word,” she teaches, “yet I am absolutely certain that in the beginning was sound — and the way you sound pretty much defines your life.” When you sing, you are not performing; you are crossing that bridge back into your own body.

She is precise about what singing is actually for, and it is not entertainment. “It is so important to feed people with music,” she says, “to bring them from their mind back to their body” (interview). Only music, she adds, “returns emotion to the body and helps us accept life.” This names why singing can shift a mood that thinking could not: so much of low, flat feeling is the result of living from the neck up, and the voice is a way back down into the self that has sensation, breath and feeling in it.

She also speaks plainly to the woman who has stopped singing, and this is the part that matters most. “Your voice is a powerful, unique instrument of self-healing,” she writes; “to make it work for you, you do not need to sing professionally at all. It is not about beauty — it is about authenticity” (from her writing on the voice). Many women carry a single old sentence — a parent, a teacher, a choir director who once said you couldn’t — and have been silent ever since. Perukua would call that one of the great thefts: not a small preference lost, but a channel of healing closed. Her own mother tried to talk her out of singing; she reports that reclaiming the voice anyway was the turning of her whole life.

And she is honest that real singing is not the same as producing the right notes. As a young jazz musician she was, by her own account, “too busy singing the notes I had learned” — technically fluent and quietly empty, riding the crashes that come after a performance. It was only in a moment of despair, she reports, that she “began to hear the music that was always there” and let her own true sound come through. The lesson she draws is the one the science quietly agrees with: the medicine is not in the polish. It is in letting the sound be honest, and letting it come from you. That is the heart of her Vocal Yoga.

Why It Works — Four Things at Once

It helps to see that singing is not one thing but four helpful things happening at the same time, which is why it reaches places a single technique cannot. The first is the breath. You cannot sing without a long, controlled out-breath, and a slow exhale is one of the most reliable ways to tip the nervous system out of alarm and toward calm. Every sung phrase is, in effect, an extended exhalation — you are doing a breathing practice without having to call it one.

The second is vibration. When you sing or hum, you are not only hearing sound, you are feeling it — in the chest, the throat, the bones of the face. That self-made vibration is part of why singing feels physically soothing in a way that listening does not; the calming signal is generated inside your own body. The third is expression. Feeling that has no way out tends to settle in the body — the familiar “lump in the throat” is exactly this, held emotion with nowhere to go. Singing gives it a route. A sound carries out what a sentence often cannot, which is why people so often find themselves moved, or even in tears, when they really sing.

The fourth is chemistry and, often, connection. Singing releases the body’s own endorphins (Dunbar et al., 2012), and when it is shared — a choir, a kitchen with a friend, a room of women — it also builds the warm sense of belonging that eases loneliness. Put the four together and the puzzle dissolves: singing calms the breath, soothes through vibration, releases held feeling, and rewards you chemically, all in the same few minutes. That is why it can lift a mood that nothing you told yourself would move. One honest note belongs here: this is support, not treatment. Singing sits happily alongside therapy or medication; it does not replace them, and Perukua is an artist and a facilitator, not a doctor. If a low, flat mood sits on most of the day for two weeks or more, that deserves a doctor’s care as well.

A Practice: Singing That Isn’t a Performance

Here is a way to use this that asks for no audience, no lessons, and no talent — only a few private minutes and permission to make an imperfect sound. Do it on the ordinary heavy days, not only the good ones.

First, sing where no one is judging. The car, the shower, the kitchen with the music up — anywhere you are unheard or unbothered. Pick one song that reaches you and sing it all the way through, out loud, badly if that is how it comes. The point is not the sound that leaves you; it is the breath, the vibration, and the fact that you let yourself be heard by yourself. Five minutes is enough to feel the shift.

Second, use the voice to release, not to perform. If you feel tight or wound up, try Perukua’s simple release: take a deep breath, and on the exhale let out a loud, open “Aaaah.” Do it five times. You may find yourself coughing or your eyes stinging — that is held tension leaving the throat, not a mistake. You can soften from there into a low hum on the out-breath, a “Huuu” that you feel in the belly and chest, and let the hum drift into a tune if it wants to. This gentle, unforcing use of the voice is the ground of Perukua’s Vocal Yoga, which teaches sound as a practice rather than a performance.

Third, let it be honest — and, when you can, shared. Do not aim for pretty. Aim for true: let the sound match how you actually feel, loud when you are angry, soft when you are tender. And once in a while, sing with someone — a friend, a group, a choir — because the lift grows when the voice is shared. If an old sentence about your “bad” voice rises up, notice it, and sing anyway. It was never about beauty.

In Closing

“Why does singing make me feel better” turns out to have a clear, encouraging answer. It is not the music around you — it is the sound coming out of you: a long calming breath, a vibration you feel in your bones, held feeling finally given a way out, and a real chemical reward for doing it. The research is consistent, and it holds even on the hardest days. Best of all, it asks nothing of your talent. So the next time something eases while you hum at the sink, trust it, and give it a few honest minutes on purpose. As Perukua reminds us, the voice is the bridge between body and soul — and it was never about beauty. It was always about coming home to yourself.

This piece is general information about wellbeing, not medical advice, and Perukua is an artist and facilitator, not a doctor. Singing can support your mood; it does not replace care. If low, empty or hopeless feelings last most of the day for two weeks or more, please reach out to a doctor — and if you ever have thoughts that life is not worth living, contact a local crisis line or emergency services. You do not have to carry it alone.
