When managing otitis externa, also known as swimmer’s ear, the general clinical advice in 2026 is to avoid the use of earplugs or cotton wool as much as possible. While it may be tempting to plug the ear to soak up discharge or protect it from the environment, doing so often creates a warm, humid, and stagnant environment that encourages the growth of bacteria and fungi. Maintaining airflow to the ear canal is a critical component of the healing process for an outer ear infection.

The Moisture Trap Effect
The primary reason we advise against internal ear protection during an infection is the microenvironment it creates within the canal.
Bacterial and Fungal Proliferation
The Problem with Cotton Wool
Many people use cotton wool to manage ear discharge. However, the fibbers of the cotton can stick to the inflamed skin or the eardrum. When you remove the cotton, it can pull away at the delicate, healing layers of the skin, causing micro tears that allow bacteria to penetrate deeper into the tissue.
Mechanical Irritation and Contamination
In 2026, clinical pathways emphasise that the skin of the ear canal is extremely sensitive during an infection.
- Friction: Repeatedly inserting and removing earplugs or cotton wool causes friction. This mechanical irritation increases swelling and pain.
- Biofilm Transfer: Earplugs, especially reusable ones, can harbour bacterial biofilms. Reinserting them into a healing ear can cause a reinfection or introduce new types of pathogens.
- Trapped Debris: Plugs can push infected debris, wax, and pus further down toward the eardrum, making it harder for the ear to clean itself naturally.
Use of Technology: Earbuds and Hearing Aids
One of the most common questions in 2026 involves the use of daily wearable technology.
- Earbuds and Headphones: These should be strictly avoided until the infection has completely cleared and the skin is no longer tender. Using them can trap bacteria and cause significant pain.
- Hearing Aids: This is more complex. If you rely on hearing aids, you should speak to your GP or audiologist. In 2026, we generally recommend leaving the hearing aid out as much as possible. If it must be worn, the ear Mold must be thoroughly disinfected with clinical grade wipes after every use to prevent the cycle of infection.
When is Plugging Permitted
There are two specific scenarios in 2026 where your doctor might recommend a temporary plug.
- Showering: You may use a piece of cotton wool coated in petroleum jelly at the very entrance of the ear to keep water out while washing. This should be removed immediately after the shower.
- Ear Wicks: If the canal is so swollen that drops cannot get in, a GP may insert a medical ear wick. This is a specialised sponge that stays in the ear for 48 to 72 hours to deliver medication. This is the only type of plug that should remain in the ear for an extended period.
To Summarise
In 2026, the clinical consensus is that less is more when it comes to covering an infected ear. Avoiding cotton wool and earplugs allows the canal to stay dry and well ventilated, which is the most effective way to kill off the pathogens causing otitis externa. Except for very brief protection during a shower, the ear should be left open to the air to facilitate rapid healing. If you must wear a hearing aid, ensure a rigorous disinfection routine to protect the healing skin.
If you have been using cotton wool to manage discharge, the next clinical step is to stop using it and consult a GP or pharmacist to see if you need an ear wick or specialised drops to manage the fluid.
Can I use foam earplugs for sleeping if I have an ear infection?
It is best to avoid them. If the pain is keeping you awake, it is better to manage the pain with paracetamol or ibuprofen rather than using earplugs, which could worsen the infection overnight.
What if my ear is leaking so much that I need cotton wool?
If the discharge is heavy, you can gently wipe the outer part of the ear with a clean tissue. If you must use cotton wool, place it very loosely at the outer bowl of the ear rather than pushing it into the canal.
How do I keep my ear dry while swimming?
If you have an active infection, you should not be swimming at all. Once healed, you can use specialised swimmer earplugs, but never use them while the ear is still inflamed.
Is it okay to wear over ear headphones instead of earbuds?
Over ear headphones are safer than earbuds because they do not enter the canal. However, they can still create a warm environment around the ear, so use them sparingly until you are fully recovered.
Why does cotton wool make my ear itch more?
The small fibbers of the cotton can irritate the already sensitised skin of the canal, triggering a histamine response that leads to intense itching.
Should I clean my earplugs after the infection is gone?
Yes. In 2026, we recommend either replacing your earplugs entirely or sterilising them with a high level disinfectant to ensure no bacteria remain to cause a future infection.
