You cannot choose their bedtime, their alarm, or whether they snore. That is what makes a shared room one of the hardest places to sleep, whether it is a dorm, a hostel, or a flat where two of you share a bedroom. The good news is that a proper trial in shared student rooms found a simple package that measurably improves sleep: agreed room rules, earplugs, and an eye mask. Here is how to put that together without starting a war.
Why Shared Rooms Are So Hard
Sharing a room means sharing three things you would normally control: the noise, the light, and the schedule. Each one can wake you on its own, and a roommate usually brings all three.
Noise tends to be the worst of them. In a study of a university residence hall in China, indoor noise was the environmental factor that most disrupted students' sleep. And a new room makes everything louder than it is. On your first nights somewhere unfamiliar, part of your brain sleeps more lightly and listens for unfamiliar sounds, which is exactly what a new roommate provides. We explain that reflex here: why you can't sleep in hotels.
Start With a Sleep Agreement
This sounds like the soft option. It is actually the part with the best evidence. In a 2022 cluster randomised trial, 364 medical students in 106 shared rooms in China received a short programme: sleep advice, agreed room rules such as lights out after 11 PM and headphones for entertainment, plus earplugs and eye masks. Their sleep quality improved significantly compared with control rooms, where it stayed flat. Asked what helped most, students picked two things: making the room rules and wearing an eye mask.
A good agreement takes two minutes and covers:
- Quiet hours. A time after which calls, music, and videos go through headphones, and main lights go off.
- Phones. Silent, face down, and screen brightness low after lights out.
- Alarms. Vibrate or a single alarm, not five snoozes. Whoever gets up first lays out their things the night before.
- Late arrivals. Coming in after lights out means a dim light or phone torch pointed at the floor, not the main switch.
- Exceptions. Exam weeks, early shifts, and guests get flagged in advance.
- A check-in. Agree to revisit it after two weeks, so raising a problem is expected rather than awkward.
Frame it as something you both get, not a list of their faults. You will almost certainly be breaking one of the rules yourself at some point.
Block the Light
An eye mask is the cheapest upgrade in this whole article, and the evidence is surprisingly good. In a 2023 study from Cardiff University published in SLEEP, 94 adults aged 18 to 35 slept a week with an eye mask and a week without. With the mask, they learned new information better the next day and scored better on an alertness test.
It matters in a shared room because light arrives on someone else's schedule: a phone screen at midnight, a laptop, a bathroom light at 6 AM. Even low light across the night is enough to fragment sleep, which we cover in is it bad to sleep with the TV on?
Deal With the Noise
- Earplugs for voices, doors, and keyboards. Properly inserted foam plugs cut high-pitched sound by around 40 decibels, and in a 2026 sleep lab study earplugs protected sleep from intermittent noise better than pink noise did. They block low rumble less well, so snoring is the part most likely to get through. Use them safely: is it bad to sleep with earplugs?
- A steady sound for what gets past them. Low, steady brown noise can make the remaining rumble stand out less, especially if you are the one who cannot sleep in silence.
- Move the head of your bed. Away from the door, the shared wall, or their side of the room, if the layout allows.
- Go to sleep first if you can. Many people find it easier to drift off before a snorer starts than to fall asleep while listening for the next snore.
If Your Roommate Snores
Snoring is not a choice, so treat it that way. Many people have no idea they snore, and a kind, private mention works far better than a sarcastic one in front of friends.
There are things they can try: sleeping on their side, avoiding alcohol close to bedtime, and nasal strips if they are congested. If you ever notice loud snoring with pauses in their breathing, gasping, or choking, suggest gently that they see a doctor, because that can be a sign of sleep apnea rather than ordinary snoring. More strategies, most of which work for roommates as well as partners: how to sleep with a snoring partner.
If You Are the One Who Needs Sound
Sometimes the problem runs the other way. You fall asleep to a podcast, rain, or music, and your roommate needs silence. A speaker on the desk fills the room, and falling asleep with earbuds in has its own problems over a whole night: is it bad to sleep with earbuds in?
The fair solution is sound that reaches your pillow and stops there. It keeps the agreement intact, because your audio never becomes their problem.
How Lullabar Fits
The Lullabar is a pillow speaker. It slides under your pillowcase, and the sound travels through the pillow fill to the ear resting on it. In a shared room it works in both directions.
- At sleep volume, your roommate hears nothing. Only your pillow carries it, so your podcast or rain sound stays on your side of the room.
- A steady floor against their noise. Rain is among the 11 built-in sounds, brown noise comes from any app over Bluetooth, and a 40mm driver keeps low sounds full at low volume.
- No phone needed. The built-in sounds and micro-SD play without a phone, so there is no screen lighting up the room.
- Timer or all night. 30, 60, or 120 minutes on the device, or 10+ hours of battery for nights when their snoring runs until morning.
- 11mm thick, 47.5 g. It fits in a drawer or a backpack, and it works with whatever pillow the room came with.
The honest limits: it masks sound, it does not soundproof. For loud voices or a party, earplugs will do more, and you cannot usefully wear earplugs and listen to a pillow speaker at the same time, so pick the right tool for the night.
Common Questions
"How do I sleep when my roommate snores?"
Combine a few things: earplugs inserted properly, a low steady sound such as brown noise to cover what gets through, and going to sleep before they do when possible. Mention the snoring kindly and privately, since many people do not know they snore, and suggest a doctor if you notice pauses in their breathing or gasping.
"How do I ask my roommate to be quieter at night?"
Propose shared room rules rather than complaining about one incident. Suggest quiet hours, headphones after lights out, and phones on silent, and agree to check in after two weeks. In a trial of shared student rooms, making room rules was one of the two things students found most helpful.
"What should a roommate sleep agreement include?"
Quiet hours, a lights-out time, headphones for any audio after that, phones on silent and dimmed, how alarms and early starts are handled, what late arrivals should do, and a date to review it. Keep it short and apply it to both of you.
"Do earplugs work for a snoring roommate?"
Partly. Foam earplugs cut high-pitched sound more than low rumble, so snoring is the part most likely to get through, especially if the plugs are not inserted deeply. Pairing them with an eye mask and a consistent routine helps, and a low steady sound can cover what remains on nights you are not wearing plugs.
"How can I listen to music at night without waking my roommate?"
Keep the sound at your pillow. A room speaker reaches both beds, and earbuds are uncomfortable for side sleepers over a full night. A pillow speaker plays through the pillow to your ear, and at sleep volume your roommate hears nothing.
The Bottom Line
You cannot control your roommate, but you can control most of what reaches you. Agree a few room rules early, block the light with an eye mask, use earplugs for voices and doors, and keep a steady sound for the rumble that gets through.
And if you are the one who needs sound to sleep, keep it at your pillow so it never becomes their problem.
Try the Lullabar for 30 nights and keep your side of the room yours.
