Should You Wear Sleep Ear Plugs? A UK Guide to Better Sleep and Ear Health

Struggling with noise at night? Whether it’s your partner’s snoring, traffic outside your window, or a flatmate watching TV at full blast, unwanted noise can be a serious sleep disruptor.

For many, sleep ear plugs offer a simple, affordable solution. But are they actually safe to use every night? And do they really work?

Here’s a deep dive into the pros, cons, and best practices for using earplugs for sleep.

Why Noise Disrupts Sleep

Even low-level background noise can disturb the delicate architecture of sleep. According to the World Health Organization, nighttime noise can cause fragmented sleep, increase stress hormone levels, and lead to long-term health issues like cardiovascular disease. In urban areas, persistent noise pollution is one of the leading external causes of sleep disruption.

Noise affects different stages of sleep in different ways. Light sleep (Stage 1 and 2) is most susceptible, meaning even mild disturbances can keep someone from entering deeper, restorative sleep. Over time, this can lead to chronic sleep deprivation, fatigue, and reduced cognitive function.

In the UK, the Environmental Noise Directive (2002/49/EC) has identified road traffic, railways, and aircraft as key sources of environmental noise. Data from the Department for Environment, Food & Rural Affairs (DEFRA) indicates that millions of residents in major UK cities are exposed to harmful noise levels at night.

What Are Sleep Ear Plugs?

Sleep ear plugs are soft, often disposable or reusable devices that sit in or over the ear canal to block out or reduce noise. They come in a variety of materials and styles:

• Foam Ear Plugs: The most common and affordable. Made of memory foam, they expand in the ear canal to create a seal.

• Silicone Ear Plugs: Moldable plugs that form a seal over the ear canal. Better suited for side sleepers due to comfort.

• Wax Ear Plugs: Often used by swimmers but popular among sleepers too. They mould to the shape of the ear and provide excellent noise blocking.

• High-Fidelity or Filtered Ear Plugs: Designed to reduce noise evenly across frequencies. Less effective for sleep but useful for environments where some sound is necessary.

Each type of earplug has its pros and cons in terms of comfort, noise reduction, hygiene, and reusability.

Do Sleep Ear Plugs Actually Work?

Yes, when used properly, ear plugs can significantly reduce ambient noise and improve sleep quality. A 2021 meta-analysis published in Critical Care found that earplugs, when combined with eye masks, improved subjective sleep quality and increased REM sleep in hospital patients—one of the most challenging environments for rest.

While most studies focus on acute settings, anecdotal and clinical reports suggest consistent improvements for chronic poor sleepers living in noisy environments. The benefits appear even greater when earplugs are part of a comprehensive sleep hygiene routine.

In real-world conditions, users report falling asleep faster, waking less frequently, and feeling more refreshed upon waking. Sleep trackers and wearable devices have even shown measurable improvements in total sleep time and sleep efficiency among earplug users.

Are Sleep Ear Plugs Safe to Use Every Night?

Generally, yes. For most people, using sleep ear plugs nightly is considered safe—but there are a few caveats:

1. Ear Wax Buildup

Regular use of ear plugs can prevent natural wax migration out of the ear, leading to blockages. This may cause hearing issues, discomfort, or even infections. According to the NHS, earwax should normally work its way out naturally. Ear plugs can interfere with this process.

2. Ear Infections

Inserting earplugs into an unclean or moist ear can introduce bacteria. Reusable plugs must be cleaned thoroughly between uses to prevent this. According to ENT UK, introducing foreign objects or substances into the ear canal increases infection risk.

3. Ear Canal Irritation

Long-term use can occasionally irritate the skin inside the ear canal, particularly with lower-quality foam plugs that expand aggressively. This irritation can cause itching, pain, or in severe cases, skin breakdown.

How to Use Sleep Ear Plugs Correctly

To minimise risk and maximise benefit:

• Clean Your Ears: Always insert ear plugs into clean, dry ears.

• Use Clean or New Plugs: Disposable foam plugs should not be reused. Reusable silicone or wax plugs must be washed with warm soapy water.

• Insert Correctly: Roll foam plugs into a tight cylinder, gently pull your ear back and insert slowly. Let them expand fully.

• Replace Regularly: Even reusable plugs have a lifespan. Follow the manufacturer’s guidance.

• Store Properly: Keep ear plugs in a clean, dry case to avoid contamination.

When Not to Use Sleep Ear Plugs

• If you have an ear infection or perforated eardrum

• If you need to hear alarms or a baby monitor

• If you’re experiencing frequent ear wax blockages

• If you have a diagnosed hearing condition or tinnitus without consulting an audiologist

If unsure, consult with a GP or an audiologist before long-term use. In the UK, a referral to audiology services can be obtained through the NHS or privately.

Alternatives to Ear Plugs for Sleep

If ear plugs aren't suitable, try these noise-reduction alternatives:

• White Noise Machines: Produce consistent background sound to mask disruptions. The Sleep Foundation supports their use for improving sleep quality.

• Noise-Cancelling Headbands: Soft fabric headbands with built-in flat speakers.

• Soundproofing Your Bedroom: Heavy curtains, double glazing, and rugs can reduce noise pollution.

• Sleep Headphones: Low-profile Bluetooth options designed for side sleeping.

• Smart Home Integration: Some smart speakers offer programmable white or pink noise features.

Expert recommendation: James Wilson, also known as 'The Sleep Geek', a sleeping behaviour expert, is a fan of ACS Custom SleepSound earplugs.

I have just been raving to a mate about some earplugs I have started using when I am sleeping in noisy environments. They are fully bespoke, fit my ears perfectly and are a bit of a gamechanger as I have never got on well with off-the-shelf earplugs, even expensive ones, as they feel uncomfortable when I sleep on my side.

When selecting earplugs, consider not just the decibel rating, but also the comfort level and fit. For side sleepers, flatter or moldable plugs tend to be more comfortable overnight.

NHS and Audiology Guidance

While the NHS doesn’t provide specific guidance on daily ear plug use, they do emphasise ear health and cleanliness. The Royal National Institute for Deaf People (RNID) suggests caution when using anything inserted into the ear canal frequently.

Those with chronic ear conditions, hearing aids, or regular wax build-up should speak to their GP or hearing specialist before adopting nightly use of plugs.

For those using ear plugs to cope with a snoring partner or noisy neighbourhood, it may be worth also exploring treatment options for snoring, or noise mitigation strategies within the home environment.

Final Verdict: Should You Wear Sleep Ear Plugs?

If night-time noise is interfering with sleep, ear plugs can be an effective, low-cost solution—especially in urban settings. When used correctly, they pose minimal risk and offer significant benefits. However, users should remain vigilant for signs of ear wax buildup, irritation, or infection. Regular cleaning and moderation are key.

For anyone experiencing persistent sleep disruption, ear plugs can be a useful part of a broader sleep hygiene strategy—alongside things like consistent bedtimes, a cool and dark sleep environment, and avoiding caffeine late in the day.
