Is it bad to sleep with white noise every night?
Key takeaways
- For most adults, quiet white noise at night is unlikely to be harmful, but the evidence that it improves sleep is very weak.
- A 2021 systematic review of 38 studies rated the evidence for continuous noise as a sleep aid as very low quality, with mixed results.
- Volume matters most. The US NIDCD says sounds at or below 70 dBA are unlikely to damage hearing even after long exposure; 85 dBA and above over long periods can.
- Avoid loud noise through headphones all night. Use a timer if you only need help falling asleep.
Is white noise good for sleep?
Maybe for some people, but research cannot say for sure. In 2021, researchers at the University of Pennsylvania reviewed 38 studies of continuous white or similar noise and sleep. Some studies found people fell asleep faster or woke less, others found noise disturbed sleep, and many were very small. Following standard grading rules, they rated the quality of evidence as very low and called for better studies before noise is promoted as a sleep aid. White noise may still help you if it covers sounds that wake you, such as traffic, a snoring partner or a neighbour's TV. Treat it as a personal preference, not a treatment.
How loud should white noise be for sleeping?
As quiet as still works for you – usually just loud enough to soften the sounds that bother you. The NIDCD (US National Institute on Deafness and Other Communication Disorders) gives these reference levels:
| Sound | Level (NIDCD) |
|---|---|
| Unlikely to cause hearing loss, even after long exposure | 70 dBA or below |
| Normal conversation | 60–70 dBA |
| Can cause hearing loss with long or repeated exposure | 85 dBA or above |
| Music through headphones at maximum volume | 94–110 dBA |
A phone cannot tell you the decibel level at your ear, so use a simple rule: if you have to raise your voice to talk over the noise, it is too loud for all night. Place the speaker away from your head rather than on the pillow. White Noise Sounds starts at a low main volume for this reason.
Is it bad to sleep with white noise in headphones?
It is riskier than a speaker, because the sound is close to your ear and easy to turn up. Sleeping on earbuds can also be uncomfortable. If you need headphones, for example in a shared room, keep the volume low and use a timer.
Can you get used to white noise and not sleep without it?
Some people find a quiet room strange after months of noise, but there is no good evidence of harm from that. If you want to stop, try lowering the volume over a few nights or use the sleep timer so the sound fades out after you fall asleep.
What is a sensible set-up?
- Start low, then raise the volume only until disturbing sounds are softer.
- Pick a sound you like. Brown or pink noise sound softer than white noise to many people; see white, pink and brown noise.
- Keep the speaker away from your head.
- Use the sleep timer (15 to 120 minutes) if you only need help falling asleep. The sound fades out over the last 30 seconds.
- Talk to a doctor if you sleep badly for weeks, or if you hear ringing in your ears.
Frequently asked questions
Is it OK to sleep with white noise all night? At a low volume it is unlikely to harm your hearing. If you notice that you sleep worse or wake with ringing ears, turn it down or use a timer.
Is brown noise better than white noise for sleep? There is no good research comparing them. Many people find brown noise softer. Try each at a low volume.
Does white noise help tinnitus? Some people with tinnitus use background sound to make it less noticeable at night. Ask a doctor or audiologist, who can advise on sound therapy.
