Sleeping With Earplugs: The Complete Guide for Day Sleepers

Even on a quiet street, cars and kids playing out can keep you wide awake when all you want to do is sleep. You've done twelve hours, the blind is down, and every car door and shout from the pavement lands like it's in the room. Over 40 years of shifts, from The King's Regiment to HM Prison Service at Strangeways, Walton and Guys Marsh, Jacobs Biscuits and Budweiser UK, a pair of earplugs has been in my kit more often than not. The Army provided me with the small foam ear plugs that were so uncomfortable to wear, but they were better than nothing. Today, earplugs have come a long way since 1987's foam version.

This guide covers whether earplugs actually help, how much noise they block, which type suits a day sleeper, how to fit them, whether they're safe every day, and what to do when they aren't enough on their own.

Do earplugs help you sleep?

Yes, for most day sleepers they help a lot. Earplugs don't make the world silent, but they turn every noise down. That matters because it's the sudden jump in sound, a door slam or a dog, that pulls you out of sleep.

The WHO Europe noise fact sheet recommends keeping bedrooms below 30 dB(A) at night for good sleep. It also names shift workers among the groups most sensitive to noise. Few day sleepers get anywhere near 30 dB at 11am, with school runs, delivery vans and bin lorries outside. Earplugs are the quickest way to close that gap.

The UK regulator agrees. The HSE's hints and tips for shift workers say that if it's too noisy to sleep, consider earplugs, white noise or background music.

What earplugs are good and bad at:

• Good at: voices, traffic hiss, birdsong, a TV through the wall, the general hum of a street in daytime.
• Less good at: deep, low sounds and vibration, such as bass music, a lorry idling, or a drill going into a shared wall. Low sound travels through the walls and your own skull, so plugs only take the edge off.

That second list is why earplugs work best as one layer, not the whole answer. More on that below.

How much noise do earplugs block? (SNR explained)

Look for the SNR on the pack. SNR stands for Single Number Rating. It's the standard figure used on hearing protection sold in the UK and Europe, given in decibels (dB). The higher the number, the more sound the plug cuts in testing.

Three things to know before you buy:

1. The rating assumes a good fit. It comes from tests with the plug fitted properly. Push a foam plug in half-heartedly and you'll get far less than the pack says.
2. Higher isn't always better for sleep. The plug you can wear comfortably for seven or eight hours beats a stronger one you pull out at noon. HSE says most adults need 7-8 hours, so comfort over that whole stretch is the real test.
3. Compare like with like. Some brands quote SNR, some quote the American NRR figure, and the two aren't the same scale. Compare SNR with SNR.

As an example, Loop's sleep model, Loop Dream, is rated 27 dB SNR, which is Loop's highest rating. It comes with foam and silicone tips in sizes XS to L, and a low-profile body made with side sleepers in mind. I've tested it properly in my Loop earplugs for sleeping review.

Foam vs silicone vs wax vs reusable: which earplugs are best for sleeping?

There are five main types. Each one trades off blocking power, comfort and cost.

If you're new to earplugs, start with a cheap mixed pack of foam. Find out what shape and firmness your ears put up with before you spend money on reusable or custom plugs.

On the worst streets I've lived, I've ended up with moulded earplugs, because nothing else stayed comfortable through a full day's sleep. You can browse the types we rate in the Sleyp shop, and a full comparison is coming in the Best Earplugs for Sleeping in the UK guide.

How do you fit earplugs properly?

Most people who say earplugs don't work have never fitted them properly. Foam plugs need a few seconds of care. Here's the method:

1. Wash your hands. You're putting something in your ear for eight hours.
2. Roll the foam plug between your finger and thumb into a thin, tight cylinder with no creases.
3. Straighten your ear canal. Reach over your head with the opposite hand and gently pull the top of your ear up and back.
4. Slide the plug in while it's still compressed, until it feels snug but not forced. Don't push it deep.
5. Hold it for 20-30 seconds with a fingertip while the foam expands to fill the canal.
6. Test the seal. Talk out loud. Your own voice should sound muffled and boomy. If it doesn't, take it out and try again.

For reusable plugs, try every tip size in the box. Most people need a different size from the one fitted at the factory, and some need a different size in each ear. A tip that's too big will ache by mid-morning; one that's too small lets sound straight past.

Side sleepers should pick low-profile plugs that sit flush with the ear. Anything that sticks out gets pushed in by the pillow, which is uncomfortable and can make you wake up to adjust it.

Are earplugs safe to wear every day?

For most people, yes, if you keep them clean and comfortable. Plenty of night workers wear them for years. A few simple habits keep it that way:

• Replace foam plugs often. Once they stop expanding properly, or look grubby, bin them.
• Wash reusable plugs as the maker suggests, and let them dry fully before you put them back in.
• Don't share them.
• Give your ears a break on days off if you can.
• Don't force them in deep. A plug should seal the entrance of the canal, not travel down it.

Earplugs can push earwax further in for some people. If your ears feel blocked, itchy or sore, stop wearing them for a while and ask a pharmacist or your GP to take a look.

Can you hear an alarm with earplugs in?

Usually, yes, if it's loud and close. A phone alarm on the bedside table at full volume will get through most earplugs. But don't find out on the afternoon before your first night shift. Test it on a day off.

If you're a deep sleeper, back it up:

• a vibrating alarm on a smartwatch or fitness band
• a phone under the pillow on vibrate as well as ring
• a second alarm across the room, so you have to get up

Think about smoke alarms too, especially if you live alone. Check you can hear yours from bed with your plugs in, and if not, look at a louder or linked alarm. To be 100% safe, I used vibrate on my watch to make sure I got up for my night shift, especially at Budweiser on the 2 days, 2 nights shift pattern.

Earplugs plus masking sound: why the combination works best

Earplugs cut the peaks. A masking sound fills the gaps. Together they do far more than either one alone.

Getting in bed when everyone else is leaving the house for school and work is great, until the next-door neighbour decides to renovate their house and starts drilling. Earplugs take the top off the drill, but you still hear it start and stop. Every start is a fresh jolt. Add a steady masking sound underneath and that start-stop is far less sudden, so your brain is less likely to wake you for it.

Which sound to use depends on the noise you're fighting:

If you're not sure which colour suits your street, my brown noise vs white noise guide walks through it, and the Noise Calibration Tool helps you match your sound to the noise outside. For the full rundown of sound colours, start with brown noise for sleep, then see pink noise for sleep, red noise and fan noise for sleeping.

Two rules for the combination:

1. Play the sound from a speaker, not earbuds, at a modest volume. With earplugs in, you'll be tempted to turn it up. Don't. It only needs to blur the background, not drown it.
2. Start it as you get into bed, not once the noise begins. A steady sound from the start means the first car door doesn't catch you out.

Light matters as much as sound for daytime sleep. For the other half of the job, see my guide to the best blackout strategies for daytime sleep.

What if earplugs aren't enough? Talking to neighbours and your council

Some noise no earplug will beat. Then it's time to deal with the source.

Start with a friendly word. The HSE's advice for shift workers includes telling your neighbours when you sleep. Most people simply don't know there's someone asleep next door at 11am. A short note through the door with your sleep times and your shift pattern often does more than any complaint.

Then fix the room. Heavy curtains, a draught excluder on the bedroom door and moving the bed off a shared wall all cut the sound before it reaches your ears.

If it's persistent and unreasonable, keep a noise diary and contact your council. Under the GOV.UK guidance on noise nuisances, councils can investigate noise that may be a statutory nuisance at any time of day or night. But the special night-noise warning rules only cover 11pm to 7am, which is exactly when a night worker is awake. So daytime noise can still be a nuisance, but you'll be relying on the general rules rather than the night ones. A diary of dates, times and what the noise was makes any complaint far stronger.

The bottom line

Earplugs are the first thing every day sleeper should own. Pick a type you can wear for a full sleep, fit them properly, and keep them clean. On the worst days, when the drill starts or the mowers come out, layer a steady masking sound underneath. Earplugs cut the peaks; Sleyp fills the gaps. Comparing apps?
