You've been looking forward to it for months. The weather's warming up, the pool's open, the sea's calling — and then, three days into your holiday, your ear starts throbbing. That dull ache turns into a sharp, burning pain every time you touch your earlobe. Sound familiar?
Swimmer's ear is one of those conditions that catches people off guard. You don't expect a quick dip in the pool to land you in a GP's waiting room, but it happens far more often than you'd think. Around 1% of the UK population develops otitis externa — the clinical name for swimmer's ear — every year, and swimmers are roughly five times more likely to get it than people who stay dry.
Here's the thing, though. Swimmer's ear is almost entirely preventable. And understanding how your ears interact with water — and what earwax actually does to protect you — makes prevention straightforward.
What Exactly Is Swimmer's Ear?
Swimmer's ear (otitis externa) is an infection of the ear canal, the narrow tube that runs from your outer ear to your eardrum. It's not the same as a middle ear infection, which sits behind the eardrum and tends to affect children after colds. Swimmer's ear lives in the outer canal, and water is usually the trigger.
The mechanism is simple. Water gets into your ear canal and sits there. That warm, damp environment becomes a breeding ground for bacteria — most commonly Pseudomonas aeruginosa and Staphylococcus aureus — and occasionally fungi like Candida or Aspergillus. The bacteria multiply, the canal becomes inflamed, and within a day or two you've got an infection that won't go away on its own.
The Cleveland Clinic confirms that swimmer's ear will not resolve without treatment. Left alone, the infection can spread to deeper tissues, cartilage, and in rare cases, the bones of the skull. That sounds alarming, and honestly, it should be — but only in the sense that it motivates you to act quickly rather than wait it out.
The Role Your Earwax Plays (and Why It Matters More Than You Think)
Here's something most people don't realise: earwax is your ear canal's first line of defence against swimmer's ear. That thin layer of cerumen coating the inside of your canal does three things simultaneously. It repels water, traps bacteria before they can colonise, and maintains the slightly acidic pH that makes the canal inhospitable to infection.
When you spend a lot of time in water, that protective layer gets gradually washed away. The CDC specifically advises against removing earwax before swimming season, stating that "ear wax helps protect the ear canal from infection." And yet, people routinely clean their ears out with cotton buds right before a holiday — which is about the worst thing you can do.
If you've got earwax buildup that's actually causing symptoms — muffled hearing, a feeling of fullness, discomfort — then yes, get it professionally removed before you swim. Microsuction is the safest option because it's a dry procedure that won't introduce water into an already compromised ear canal. But if your ears are fine, leave the wax alone. It's doing its job.
How to Spot Swimmer's Ear Early
The sooner you catch it, the faster it clears up. Most cases resolve within a week with the right ear drops, but that timeline stretches considerably if you ignore the early signs. NHS inform Scotland describes the progression clearly:
The first 24–48 hours bring itching inside the ear canal and a vague sense of fullness, almost like your ear is slightly blocked. At this stage, many people assume they've just got water trapped in there and carry on swimming. That's the mistake.
By day two or three, the itching turns to pain — particularly when you tug your earlobe, press on the tragus (that small flap of cartilage in front of your ear canal), or move your jaw while chewing. You might notice redness around the ear opening and some clear, watery discharge.
If left untreated, the pain intensifies. The discharge can become thick and pus-like, hearing in the affected ear drops noticeably, and the lymph nodes around your ear and neck may swell. At this point, you need antibiotic ear drops from your GP or pharmacist — there's no home remedy that will fix an established infection.
| Stage | Symptoms | What to Do |
|---|---|---|
| Early (Day 1–2) | Itching, mild fullness, slight discomfort | Stop swimming, dry ears thoroughly, monitor closely |
| Moderate (Day 2–4) | Pain when touching ear, redness, watery discharge, muffled hearing | See your pharmacist or GP for ear drops |
| Severe (Day 4+) | Intense pain, pus-like discharge, swollen lymph nodes, significant hearing loss | Seek medical attention promptly |
Who's Most at Risk?
Swimmer's ear can affect anyone, but certain groups are more vulnerable. NHS inform Scotland notes that the condition affects roughly 1 in 10 people at some point in their lives, with a slightly higher prevalence in women and adults aged 45 to 75.
You're at greater risk if you have skin conditions like eczema or psoriasis in or around your ear canal. These conditions compromise the skin's barrier function, making it easier for bacteria to take hold. People who wear hearing aids or earbuds regularly also face higher risk — the devices can trap moisture and introduce bacteria into the canal.
Freshwater swimmers face a particular challenge. The Cleveland Clinic points out that lakes, rivers, and ponds contain more bacteria than chlorinated swimming pools. If you're an open-water swimmer in Devon — and there's no shortage of beautiful rivers and coastline here — your ears need extra attention.
Children are another high-risk group. They tend to spend longer in the water, they're less likely to dry their ears properly afterwards, and their ear canals are narrower, which means water gets trapped more easily. If you've got children who swim regularly, teaching them the head-tilt technique after every session is one of the simplest things you can do.
A Practical Prevention Guide
The good news? Preventing swimmer's ear is genuinely straightforward. The CDC, NHS, and Cleveland Clinic all agree on the same core strategies, and none of them require expensive equipment or complicated routines.
Before You Swim
Consider ear plugs. Soft silicone ear plugs are the most effective at preventing water from entering the ear canal. Research published in the Journal of Otolaryngology found that silicone moulds outperformed foam plugs and cotton wool by a significant margin. You can buy them from most pharmacies for a few pounds, or ask your audiologist about custom-fitted swim moulds if you're a regular swimmer.
Don't clean your ears out. This bears repeating. Your earwax is protecting you. If you've been using cotton buds, stop — they push wax deeper, scratch the canal lining, and remove the very barrier that keeps water and bacteria out.
Check the water quality. If you're swimming in open water, check local water quality reports. Polluted or stagnant water carries a significantly higher bacterial load. The Outdoor Swimming Society publishes regular updates on bathing water quality across the UK.
After You Swim
Tilt and drain. Immediately after getting out of the water, tilt your head to each side and hold it there for 10–15 seconds. Gently pull your earlobe in different directions while your ear faces downward — this straightens the ear canal slightly and helps water escape.
Dry thoroughly. Use a clean, soft towel to pat the outer ear dry. If you can still feel water inside, a hair dryer on the lowest heat and lowest fan setting, held about 30 centimetres from your ear, will evaporate the remaining moisture without causing damage.
Don't poke anything in there. No cotton buds, no tissue corners, no twisted towel edges. The skin inside your ear canal is remarkably thin — about 0.1mm in places — and even gentle contact can create micro-abrasions that bacteria will exploit.
The Homemade Drying Drops Debate
You might have heard about using a mixture of white vinegar and rubbing alcohol as ear-drying drops after swimming. The idea is that the alcohol helps evaporate water while the vinegar restores the canal's acidic pH. Some ENT specialists do recommend this approach for people who swim frequently.
But there's a catch. The CDC advises against using any ear drops if you have ear tubes, a perforated eardrum, an existing ear infection, or any discharge from your ear. If you're unsure whether your eardrums are intact, don't use them. And if you're already using olive oil drops to soften earwax, don't add vinegar drops on top — speak to your practitioner about the right sequence.
What to Do If Water Gets Trapped
That muffled, underwater feeling after swimming is usually just water sitting against your eardrum. It's uncomfortable and annoying, but it's not an infection — yet. The key is getting the water out before bacteria have time to multiply.
The gravity method works best. Lie on your side with the affected ear facing down, resting on a towel. Stay there for five to ten minutes. Gravity will do most of the work. You can gently pull your earlobe downward and backward to help open the canal.
Yawning and chewing can also help. Both movements change the shape of your ear canal slightly, which can break the surface tension holding the water in place. Some people find that chewing gum for a few minutes after swimming does the trick.
What you shouldn't do is try to suction the water out with your finger, jam a cotton bud in to absorb it, or pour hydrogen peroxide into your ear. These approaches either push the water deeper, damage the canal lining, or introduce chemicals that irritate already-vulnerable skin.
If water remains trapped for more than 12 hours despite these techniques, and you're starting to feel itching or discomfort, it's worth seeing a professional. There may be earwax buildup trapping the water behind it — a common scenario that microsuction or ear irrigation can resolve quickly.
When Swimming Season Meets Earwax Problems
Here's a scenario we see regularly at the clinic. Someone comes in mid-July with what they think is swimmer's ear, but the real problem is a plug of earwax that's been building up for months. Water from swimming has become trapped behind the wax, creating a warm, stagnant pocket that's now infected.
The treatment in this case isn't just antibiotics — the wax needs to come out first, so the ear drops can actually reach the infected skin. This is where professional earwax removal before swimming season makes a real difference. If you know you're prone to wax buildup, booking a microsuction appointment before the summer starts is one of the smartest preventive steps you can take.
We'd recommend using olive oil drops for three to five days before your appointment to soften the wax, making removal quicker and more comfortable. After that, your ear canal is clear, your natural wax production resumes its protective role, and you can swim with confidence.
Swimming with Ear Conditions: What You Need to Know
Not everyone starts swimming season with healthy ears. If you've got an existing ear condition, the rules change.
If you have a perforated eardrum, water entering the middle ear can cause a serious infection. Custom-fitted swim moulds are strongly recommended, and you should avoid submerging your head entirely if possible. Your GP or ENT specialist can advise on the specific precautions for your situation.
If you wear hearing aids, remove them before swimming (obviously), but also make sure your ear canals are completely dry before reinserting them afterwards. Hearing aids can trap residual moisture against the canal wall, creating exactly the conditions that lead to otitis externa. For a full guide to ear care as a hearing aid wearer — including daily cleaning routines and how often to book professional removal — read our complete hearing aid ear care guide.
If you've recently had earwax removed, wait at least 24 hours before swimming. Your ear canal needs time to re-establish its protective wax layer. Swimming immediately after removal leaves the canal temporarily more vulnerable to infection.
If you've had swimmer's ear before, you're more likely to get it again. The NHS advises using ear plugs consistently and drying your ears thoroughly after every swim. If you get recurrent episodes, your GP may recommend prophylactic ear drops to use after swimming.
