What to listen to when you can't sleep

Podcasts: the hardest case

The problem with podcasts isn't that they're interesting. It's that the craft of making them is the craft of preventing a drift — a hook in the first thirty seconds, a tease before the break, a question left deliberately open, an autoplay queue that hands you to a stranger at three in the morning. You can be exhausted and lose anyway, because the audio was engineered to win.

If you're keeping them, the salvage is to re-listen to episodes you already know, kill autoplay, and pick the dullest thing in your library, sincerely.

Audiobooks: better, with one flaw

Audiobooks are a genuine improvement. The narration is steady, there are no ad breaks at double volume, and a good narrator's voice is closer to a lullaby than a host's is.

The flaw is structural. A novel is a machine for making you want the next chapter, and it doesn't stop being one at midnight. You surface at the end of a scene with the plot still open, and the open plot is the thing that keeps you present. Non-fiction you've read before works better than a thriller you haven't — the less a book withholds, the less it costs you to let go of it.

Music: the one with real evidence, and a catch

Music is the only option here with a serious body of research behind it, and the findings are worth reading precisely.

A Cochrane review updated in 2022 pooled thirteen randomised trials — about a thousand adults with insomnia symptoms, listening to pre-recorded music for twenty-five to sixty minutes a night, for anything from three days to three months. On the Pittsburgh Sleep Quality Index, the music groups rated their own sleep substantially better than the groups given nothing, an effect of roughly one standard deviation, judged moderate-certainty. No trial reported any adverse event.

Then the honest part. Three of those trials also measured sleep objectively rather than by questionnaire, and found no clear difference on any of it — not in how long people took to drop off, how long they stayed down, or how broken the night was. What music reliably changes is the experience of the night. Whether it changes the night itself is, on this evidence, unproven.

There is also a catch that surprised the people who found it. In a 2021 study at Baylor, fifty young adults listened to popular songs before bed in a lab, some in their original lyrical versions and some stripped to instrumentals. The instrumental versions produced more nighttime earworms, and worse sleep as measured on polysomnography. A survey of 199 people in the same paper pointed the same way: frequent music listeners reported persistent nighttime earworms, and those earworms tracked with worse sleep quality. Fifty people is a small room, and one lab, and it deserves replication. But the mechanism is plausible and slightly grim — a melody with no words is easy for a sleeping brain to keep rehearsing, and it does, during every awakening.

Which makes the usual advice to "put on something instrumental" less obviously safe than it sounds. Familiar, unloved, and slow beats beautiful.

What the Reddit threads get right

Search what to listen to to fall asleep reddit and you will find the same answers over and over: rain sounds, a long documentary about something dull, an episode you've heard forty times, someone reading Wikipedia aloud. The crowd has arrived, without the vocabulary, at exactly the right principle. All of those share one property — they withhold nothing. There is no reason to stay for the end, because the end was never the point.

The crowd's weakness is supply. Found audio is dull by accident, which means it is also loud in places, ad-broken, and followed by an autoplay recommendation.

Sleep stories: dullness on purpose

Sleep stories are what happens when you design for that property instead of stumbling into it: endings given away in the first minute, no stakes introduced at all, a narrator instructed to flatten rather than perform, a volume line that descends and never comes back up, and a recording that simply ends.

That is the whole of the category, and it is worth being plain about what it is not. It is not a treatment, it makes no promise about your night, and persistent insomnia deserves a clinician rather than a playlist. What it offers is the one thing the other four options are structurally bad at: something to occupy a busy mind that has no interest whatsoever in keeping it.

Ours is written to lose your attention on purpose — every story gives away its ending before you've had a chance to care about it.
