There's a particular kind of 3am I know well. Sometimes it's loud – my mind sprinting ahead of itself, one thought triggering three more, the room feeling too small for whatever's happening in my head. Other times it's heavy – a kind of 3am where thoughts arrive slowly and land hard, circling the same worry until it feels like the only thing that's ever been true.

Both are versions of the same problem: sleep not coming easily. And for me, as someone who lives with bipolar disorder, they're not random. Racing thoughts in a hypomanic stretch, intrusive negative thoughts when I'm low. Same problem, opposite weather, and either way my mind won't let my body rest.

Music has become one of the ways I navigate both. Not a cure, not a substitute for the psychiatrist and therapist who help me manage the condition itself – but a tool I reach for consistently, and one that works differently depending on which version of 3am I'm in.

Two states, two soundtracks

When I'm hypomanic, what I need is something that slows me down without fighting me. Music that's too sparse or too slow can feel like it's asking too much too fast – like being told to calm down when you can't. What works better is something with enough movement to meet the racing, but that gradually, almost sneakily, brings the tempo down underneath me.

Said and Done by Nils Frahm does this for me. There’s a repetitive piano note running through it that meets my racing thoughts almost head-on, rather than trying to talk over them. For a while it can feel uncomfortable — sitting inside that repetition while my mind is still moving fast — but it holds the racing in place, and slowly, without my really noticing when, lets it dissipate.

It's different when I'm depressed. My thoughts are already slow, already heavy. What I don't need is more weight, so I reach for warmth instead. Something that doesn't try to lift me out of the feeling, just sits with me in it without making it worse. Consistency matters more than intensity here.

#3 (Rhubarb) by Aphex Twin is the one I return to. The loop at its centre never quite resolves musically, and somehow that unresolved quality is what holds me. It sounds like it should feel unsettled, but I find it hopeful — almost optimistic — and it lets me sit inside the heaviness without adding to it.

There’s a name for this in music therapy – the Iso principle: meeting a state as it actually is before trying to shift it, rather than reaching straight for the opposite of how you feel. Both tracks do this. Neither tries to talk me out of where I am. They sit with it first, and only then start to move.

Why this actually works

There's real science behind why music can shift us toward sleep, and it's worth understanding – not because you need to know the mechanism to feel the effect, but because it explains why the right music matters, not just any music.

Certain frequencies genuinely support the transition into sleep. Delta waves, the slow brain activity linked to deep, restorative rest, and theta waves, which emerge in that drowsy window just before sleep, both respond to what we listen to in the run-up to bed. Low, rumbling tones under 250 Hz tend to feel grounding – a bit like a steady hand on your back. And tempo matters more than people expect: music at 80 beats per minute or slower gives your body permission to follow it downward, the way a slowing heartbeat invites your own to match it.

Music can also nudge the body chemically. It's been linked to increases in melatonin, the hormone that signals "night mode," and it supports serotonin, which helps stabilise mood and regulate sleep cycles. None of this is instant or magic. But add it all up, the frequency, the tempo, the chemistry, and you start to see why the right track at the right moment can do something silence alone often can't.

The bit that matters most: consistency

The single biggest thing I've learned isn't about which frequencies or tempos are "correct." It's that the music has to become familiar. A song doesn't soothe you because it's objectively soothing – it soothes you because your body has learned that this sound means safe, this means rest is coming.

I discovered this properly not through my own sleep but through my daughter's. In the chaos of early parenthood, I didn't reach for a traditional lullaby – I found myself softly singing De La Soul's Ring Ring Ring at 2am, night after night. It wasn't Twinkle, Twinkle. But it became ours. Eventually her whole body would soften the moment she heard it, because the cue had been repeated enough times to mean something.

That's what I try to build for myself on the hard nights, too. Not the perfect song, but a known one – something my nervous system has learned to trust.

If sleep is hard for you too

If you recognise either version of that 3am, the racing kind or the heavy kind, you're not alone in it. And you don't have to build a solution from scratch. Music won't fix what's underneath a sleepless night, but it can become one steady, repeatable signal to your body that says: it's safe to rest now.

Start small. Pick two or three tracks, not a sprawling playlist, just a handful you can keep coming back to, and use them consistently rather than hunting for something new every night. Let familiarity do the work that novelty can't.

And notice where you actually are before you choose. Racing, heavy, somewhere in between. Don't reach straight for whatever you've been told should be relaxing if it doesn't match how you actually feel. Let the music sit with you first, and only then ask it to move you somewhere else. That's really the idea underneath all of this: listen intentionally, pick music that meets you where you are, and let it carry you to where you want to be. I'm exploring this further through guided listening sessions built specifically for this kind of work, but you don't need a bespoke session to start. The same idea works with music you already know and love. You just have to listen for it.
