Earplugs are a popular solution for light sleepers struggling with external noise. They can improve sleep quality by blocking out unwanted sounds, from loud traffic to a snoring partner. However, some people question their safety, as long-term use may cause earwax buildup, leading to temporary hearing loss, tinnitus, or ear infections. While earplugs can be a quick fix, they may not address the root cause of sleep issues, and alternatives like white noise machines or soundproofing offer valid options for those wanting to avoid potential side effects.

The benefits of earplugs for sleep
Earplugs are a popular solution for those who are sensitive to noise and struggle to sleep in a noisy environment. They can be particularly useful for those who live in noisy areas, such as near an airport or a freeway, or for those who have loud roommates or neighbours.
Benefits of earplugs for sleep
Earplugs can significantly improve the quality of your sleep by blocking out sounds that would otherwise wake you up or interrupt your sleep. Research has shown that the quality of sleep we get plays a role in our physical and mental health and can affect a wide range of conditions, including hypertension, diabetes, depression, obesity and cardiovascular disease. By using earplugs, you can ensure you get uninterrupted sleep, helping you feel more rested.
Earplugs are generally safe and can be an effective tool for light sleepers to block out sounds, such as a snoring partner, barking dogs, or traffic noise. They form a seal around the entrance to the ear canal and physically block the vibrations that would otherwise reach the eardrum and be interpreted as sound by the brain.
Foam earplugs are the most inexpensive option and are soft, making them a good choice for sleeping. Custom-made earplugs are also an option; these involve making a mold of your ears to create a pair of reusable earplugs that match their shape.
Potential drawbacks
While earplugs can be beneficial for improving sleep quality, they do have some potential side effects, especially with regular use. One of the main risks is the buildup of earwax, which can occur when earplugs interfere with the natural flow of earwax in and out of the ear canal. This can lead to temporary hearing loss, tinnitus, and even permanent hearing loss if not addressed. Ear infections are another potential complication, which can be caused by bacteria growing on earplugs or by the buildup of earwax.
To mitigate these risks, it is important to regularly clean or replace earplugs, especially foam ones, which provide a good environment for bacteria. It is also recommended to avoid inserting them too far into the ear and to consult a healthcare professional if you experience any issues.

Natural alternatives to earplugs
Earplugs are an effective way to block out unwanted noise and get a good night's sleep. However, long-term use can interfere with the self-cleaning process of earwax, leading to a buildup that can cause tinnitus or even hearing loss. If you're looking for natural alternatives to earplugs, here are some options:
White Noise Machines
White noise machines produce a consistent, soothing sound that helps to mask unwanted environmental noise. They have been shown in hospital studies to significantly improve sleep by reducing the difference between background noise and sudden, startling noises. White noise machines can be especially effective for blocking out noises like barking dogs, chatter, traffic noise, and more. Some people may not prefer having speakers in their bedroom, in which case there are white noise earbuds available.
Moldable Earplugs
If you're specifically looking for an alternative to the traditional foam earplugs, moldable earplugs made of wax or silicone are a good option. Unlike foam earplugs, these only seal the entrance of the ear canal and do not need to be inserted deeply. They are simply rolled into a ball, pressed against the ear, and flattened. While they may not be as effective as foam for low-frequency noise, they are still respectable noise blockers with a noise reduction rating (NRR) of around 22 to 23 dB. Combining moldable earplugs with a white noise machine can further enhance their noise-blocking capabilities.
Over-the-Ear Noise-Cancelling Headphones
If you're a back sleeper, over-the-ear noise-cancelling headphones can be a comfortable and effective alternative to earplugs. Options like the Bose QC35 ANC headphones are designed to block out low-frequency noise, including airplane and traffic noise, generators, humming machines, and bass-heavy music. They can also be quite effective at blocking out snoring noise. Additionally, you can wear earplugs underneath these headphones for even better noise cancellation.
Soft Memory Foam Pillow
For side sleepers, a soft memory foam pillow might help reduce noise by providing a comfortable surface that conforms to your body. It can help block out noise from neighbors or traffic, especially when combined with other noise-reducing measures.

Risks of sleeping with earplugs
While earplugs can be a great way to block out surrounding noises that disturb your sleep, they do come with a few risks and side effects, especially with regular use.
One of the most commonly cited risks of sleeping with earplugs is the potential for earwax buildup. Earplugs can push earwax back into your ear, causing a blockage. This can lead to several problems, including temporary hearing loss, tinnitus (ringing in the ears), and discomfort or itching. Earwax buildup can be treated with ear drops or removed by a doctor, but it's important to be cautious to avoid these issues.
Another risk associated with earplug usage is the possibility of ear infections. Ear infections can occur due to a buildup of earwax or the growth of bacteria on the earplugs themselves. These infections can be painful and, if left untreated, can lead to lasting complications such as hearing loss. It is important to clean or replace earplugs regularly to reduce the risk of infection.
Additionally, it is important not to insert earplugs too deeply into the ear canal. Doing so can irritate the lining of the eardrum, causing discomfort and potentially impacting your hearing. It is recommended to insert earplugs only far enough to block sound effectively, ensuring comfort during sleep.
While less common, there is also a risk of earplugs affecting your ability to hear alarms or emergency alerts. Custom-made earplugs, in particular, are very effective at blocking out all noises, which can be concerning in emergency situations. This risk can be mitigated by using earplugs with a vent or a small hole, which helps equalize pressure in the ear and may allow for some important sounds to be heard.
Finally, while not a direct health risk, there is a potential for dependence on earplugs for sleep. Some people report having difficulty sleeping without earplugs after prolonged use, requiring a gradual adjustment period to sleep without them.

Types of earplugs for sleep
If you're struggling to sleep due to noise, earplugs can be a great solution. They form a seal around the entrance to the ear canal, blocking sound vibrations from reaching the eardrum and being interpreted as sound by the brain.
There are several types of earplugs available for sleeping, each with its own pros and cons in terms of comfort, durability, and noise reduction capabilities. Here are some of the most common types:
- Foam earplugs: Foam earplugs, such as Mack's Slim Fit Foam Earplugs, are designed to fit inside the ear canal. They are often made of soft, compressible foam that can be rolled and inserted into the ear, where they expand to seal the canal. Foam earplugs are usually disposable and are a good choice for blocking out intermittent noises.
- Silicone earplugs: Silicone earplugs, like Mack's Pillow Soft Silicone Putty Earplugs, are also designed to fit inside the ear canal. They are made of soft, mouldable silicone that can be shaped to conform to your unique ear opening, creating an airtight seal that blocks out noise. Silicone earplugs are reusable and are known for their comfort and effectiveness in staying in place throughout the night.
- Wax balls: Wax balls are another type of earplug that can be moulded to fit your ear canal. They are typically made of a pliable wax material that softens with body heat, allowing them to conform to the shape of your ear. Wax balls have the advantage of being reusable and providing a good seal, but they may not be as comfortable for side sleepers due to their protruding design.
- Custom otoplastics: Custom otoplastics are earplugs that are custom-made to fit your ears perfectly. They are typically more expensive than other options but offer superior comfort and noise reduction. Custom otoplastics are often recommended for those who require consistent and reliable noise protection.
- Filter earplugs: Filter earplugs, such as Alpine SleepSoft earplugs, are designed with noise filters that allow some sound to pass through while attenuating (reducing) the volume of ambient noise. They are ideal for those who want to muffle background noise while still being able to hear important sounds, like an alarm clock.
- Adjustable noise reduction earplugs: Loop Dream earplugs and Loop Quiet 2 earplugs offer adjustable noise reduction, allowing you to customise the level of sound blocking based on your needs. They are designed for comfort and are a good choice for those who want more control over their noise reduction capabilities.
It's important to note that while earplugs can be extremely helpful for improving sleep quality, long-term use may interfere with the natural self-cleaning process of earwax, potentially leading to a buildup of wax, tinnitus, or even hearing loss. Therefore, it is recommended to clean your earplugs regularly, avoid using them every night if possible, and consult a healthcare professional if you experience any ear-related issues.

Caring for and cleaning earplugs
Earplugs are a great way to block out noise and get a good night's sleep. However, they can get dirty quickly if not properly maintained, with wax and dirt building up on the earplug. This can lead to tinnitus or even hearing loss if not addressed. Therefore, it is important to care for and clean your earplugs regularly. Here are some detailed instructions on how to do just that:
Caring for Your Earplugs:
- Store your earplugs in a container when not in use. If they didn't come with one, use a small plastic container.
- Do not get the body of earmuff-style earplugs wet as the inner parts can be damaged by water.
- Wash reusable earplugs regularly to maintain their effectiveness and protect your ear health.
- Do not use disposable earplugs more than once. These are typically made of silicone putty or soft wax and are not meant to be cleaned.
Cleaning Your Earplugs:
- Fill a small bowl with warm water and add a cleaning solution. Soap or dish detergent works well, but hydrogen peroxide is also recommended by audiologists.
- Let the earplugs soak in the solution for a few minutes. This helps loosen earwax and dirt.
- Use a new toothbrush and a fresh bowl of soapy water to gently scrub away any remaining debris. Be gentle to avoid damaging the earplugs.
- Rinse the earplugs under cold water to remove any remaining soap and dirt.
- (Optional) Disinfect your earplugs with an alcohol spray to prevent bacterial buildup.
- Allow the earplugs to air dry naturally. Do not use a hair dryer or cloth to speed up the process.
By following these steps, you can keep your earplugs clean and effective, ensuring a good night's sleep without any interruptions!
