Ocean Sounds for Sleep

3:17 AM. I know because the clock is the first thing I check now, like checking the time will somehow explain why I'm awake again. The heating pad has gone cold. Ken is asleep — genuinely asleep, the kind where his breathing changes and he makes that small sound that isn't a snore but would be a snore if I told him about it, which I won't. Kona's at the foot of the bed, one ear cocked, because she heard me shift and she's deciding if this is a get-up or a roll-over.

It's neither. It's the third time tonight. My hip woke me at 12:40. My shoulder at 2:10. This time it's nothing specific — just the all-over hum, the baseline buzz of a nervous system that doesn't know how to be off. Like my body's running a background process I can't kill.

Samba's on Ken's pillow. She opened one eye when I moved. Closed it. Her assessment: the human is doing the awake thing again. Not my department.

3:17 AM

I've been awake at 3am so many times this year that I've developed a taxonomy. There's the Pain Wake — sharp, specific, you know exactly what dragged you out. There's the Fog Wake — you surface into confusion, don't know where you are for a second, the room feels wrong. There's the Anxiety Wake — heart going, mind racing through tomorrow's list that you can't handle and you know you can't handle it and knowing that makes it worse.

And then there's the Hum Wake. That's tonight. No spike, no reason, just — on. Like someone left the lights running in a building that's supposed to be closed.

I reach for my phone. Not to scroll — I've learned that lesson, the blue light article is coming eventually, Ken has opinions — but to start the sounds. I open the app, find my saved mix, tap play. And the ocean fills the dark room, and I close my eyes, and sometimes it works and sometimes it doesn't, and tonight I don't know yet which one it'll be.

The Thing Your Brain Does That Mine Does Worse

Ken explained this to me with a whiteboard once. He'd drawn brain waves — literal squiggly lines, he is not an artist — and he was pointing at them with a wooden spoon because we couldn't find the laser pointer.

In normal sleep, your brain cycles through stages. Light sleep (stage 1-2), deep sleep (stage 3, also called slow-wave sleep), and REM. The deep sleep stages are where your body does its repair work — glymphatic clearanceThe brain's waste-removal system that operates primarily during deep sleep, flushing out metabolic debris and inflammatory proteins, tissue repair, immune regulation, all the maintenance your body queues up during the day¹.

In fibromyalgia brains — and I'm saying "brains" but I mean mine — something goes wrong with this cycle. EEG studies since the 1970s have documented a pattern called alpha-delta sleepA sleep abnormality where alpha brain waves (wakefulness signals) intrude into delta waves (deep sleep), preventing truly restorative rest — alpha brain waves, the ones associated with being awake and alert, crash into the delta waves of deep sleep². It's like your brain is trying to sleep and watch the door at the same time. Hypervigilance, even unconscious.

The result: you get hours of sleep that don't count. You wake up and your body hasn't repaired. The pain compounds. The fog thickens. And the next night, the alarm system is even more wound up, so the alpha intrusion is worse, so the sleep is worse, so the pain is worse.

It's a loop. I live inside it. Most fibro patients do.

Pink Noise, White Noise, and the New Study That Complicated Everything

For years, the recommendation was simple: play pink noise. Pink noise — which sounds like a waterfall, or steady rain, or a fan, with more bass than the static hiss of white noise — had studies behind it suggesting it could enhance deep sleep and improve memory consolidation⁴.

I used pink noise apps for months. The sound of digital rain. It was fine. It wasn't the ocean. It felt like sleeping in a server room with better branding.

Then in February 2026, Penn Medicine published a study that changed the conversation. Researchers found that pink noise actually reduced REM sleep and may worsen overall sleep quality⁵. The study found earplugs — just silence — outperformed pink noise for protecting sleep architecture.

I read that study at 4am on a Tuesday and I threw my phone onto the pillow next to Samba, who was not amused.

Here's why it matters: for months I'd been adding sound to my sleep environment because studies told me to. And now a rigorous study was saying that sound — even the "right" kind — might be interfering with the very sleep stages my fibro brain already can't access.

What I Actually Built

I'm a coder. When something doesn't work, I don't abandon it — I refactor.

After the Penn study, I stopped running sound all night. Instead, I built myself a sleep ritual. Not a "routine" — I hate that word, it implies consistency, and fibro laughs at consistency. A ritual. Something I do when I can, in the order I can manage it.

• The recording. I have a 45-minute recording from Bayshore — real waves, not generated. I'll get to how I got it in a minute. I play this at low volume while falling asleep.
• The timer. Auto-off after 30 minutes. This is the important part. The sound helps me fall asleep. It doesn't run all night. After the Penn study, I want my deep sleep stages left alone.
• The fallback. When I wake at 3am — not if, when — I can restart the recording manually. Another 20-minute timer. Just enough to coax my brain back from the Hum Wake into something closer to drowsy.
• The rule. If the sound doesn't work within 20 minutes, I stop trying. I get up, go to the couch, let Kona follow me, and read something boring until my body gives in. Fighting insomnia in bed makes the bed into a battlefield. I won't do that.

Ken thinks my sleep system has too many conditionals. I told him it's basically a switch statement with a default case. He laughed. Then he added it to the spreadsheet.

You Can't Record the Ocean. I Tried.

This is the part where I admit something embarrassing.

I went to Bayshore with Ken's phone — because mine doesn't have enough storage, because I have 47 photos of Kona on the beach and I won't delete any of them — and I tried to record the waves. I stood on the dune above the water during an incoming tide because that's when the surf is loudest, held the phone up, pressed record, and got: wind. Just wind. Forty minutes of wind with occasional wave sounds buried underneath, plus two seagulls having an argument and my own breathing.

Ken tried next. He put the phone in a ziplock bag and wedged it between two pieces of driftwood near the base of the dune. Better. You could hear the waves. You could also hear every grain of sand hitting the bag, which sounds less like "ocean ambiance" and more like "microphone being assaulted."

Third attempt. Ken bought a cheap lapel mic, clipped it to the inside of a coffee mug — I'm not making this up — and positioned the mug sideways on the sand to act as a wind baffle. It worked. Not perfectly. There's a low rumble that might be the highway. But the waves are there, and the rhythm is right, and when I play it at night my brain goes oh, that. I know that. And something unclenches.

The apps have nicer recordings. Smoother. More professionally produced. They don't work as well. I think my brain knows the difference between the ocean and a recording of an ocean, and it knows the difference between our ocean and someone else's. The little imperfections — the gravel in the wave, the bird at minute 23, the moment where you can hear Kona bark once in the background because she saw a crab — those are what make my nervous system believe it.

The Nights It Works and the Nights It Doesn't

I want to be specific because vague claims are useless.

On nights when my pain is below a 6 and I haven't had caffeine after 2pm and I've been to the bay that day: the recording helps me fall asleep in about 15-20 minutes, which is roughly half what it takes in silence. I wake once or twice instead of three or four times. Total sleep: maybe 6 hours instead of 4.5. I'll take it.

On nights when my pain is a 7+: the recording is background noise. My brain can't latch onto it because the pain signal is louder. Those nights, nothing auditory works. Those are the nights I end up on the bathroom floor because the tile is cold, and Kona finds me, and Samba comes in eventually and sits in the doorway like a small orange bouncer evaluating whether I'm allowed back in bed.

On nights when the fog is bad but the pain is moderate: the recording is most useful. The fog-brain can't think its way out of the insomnia loop, but it can follow a rhythm. The waves give it something to track that isn't panic. In-out. In-out. Not my breathing — the ocean's. And somehow my breathing follows.

A 2022 randomized trial found that diaphragmatic breathingDeep belly breathing that activates the vagus nerve and shifts the nervous system from fight-or-flight toward rest-and-digest mode combined with auditory cues reduced pain intensity in fibromyalgia patients compared to controls, with the combined intervention outperforming either alone⁷. I didn't know that study existed when I started matching my breath to the waves. I just did it because my body wanted to.

Sometimes your body knows the research before your brain reads it.

Kona Sleeps Better Than All of Us

I watch her sometimes. When I'm awake at 3am and the recording hasn't worked and I'm on the couch with a blanket and my phone and the low-level fury that comes from being exhausted and unable to sleep.

Kona will be on the floor next to me. Not on the couch — she knows the couch is mine at 3am, she respects the perimeter. She's on the rug, on her side, and her breathing is deep and slow and her legs twitch sometimes because she's dreaming, probably about the beach, probably about the crab she almost caught last week but didn't because crabs are faster than she thinks they are.

Her sleep architecture is perfect. Her brain cycles through the stages the way brains are supposed to. No alpha intrusion. No hypervigilance. She goes from awake to asleep in under a minute and she stays there until morning or until I make a sound that triggers her "is the human okay" protocol.

I'm not jealous. That's a lie. I'm extremely jealous. I'm jealous of my dog's sleep the way some people are jealous of their friends' vacations. She has something I used to have and may never have again and she doesn't even know it's remarkable.

But here's the thing that isn't jealousy: listening to her breathe helps. More than the recording, some nights. Her breathing has the same rhythm as the waves — in, pause, out, pause — and my body trusts it because it's coming from something warm and alive and three feet away.

Samba's breathing is too fast. Cat breathing is rapid and light and it doesn't do the same thing. Ken's is good but he shifts and then my brain goes is he awake? should I be quiet? did I wake him? and then I'm monitoring instead of resting.

Kona just breathes. In and out. Like the water.
