Quick Summary: Swimmer's ear (otitis externa) is an outer-ear-canal infection caused by water trapped in the ear, and it's very preventable. After every swim or bath, drain, dry, and protect: tilt the head to each side, dry the outer ear (a hair dryer on the lowest, coolest setting a foot away helps), and never push cotton swabs into the canal. For frequent or prone swimmers, well-fitting earplugs or an ear-covering swim cap and doctor-approved drying drops add protection. Watch for pain, drainage, or muffled hearing — those mean it's time to see a doctor. Prevention keeps kids in lessons, which are a core layer of drowning protection.

👂 What is swimmer's ear — and why does it sideline so many kids?

Swimmer's ear, or otitis externa, is an infection of the outer ear canal — the tube leading from the eardrum to the outside of the head. It develops when water stays trapped in the canal after swimming or bathing, creating a warm, moist place where bacteria multiply. This is different from the middle-ear infection kids get after a cold: that one sits behind the eardrum, while swimmer's ear affects the canal itself. A quick tell is that swimmer's ear usually hurts more when you gently tug the earlobe or press the little bump in front of the ear. Because it's tied to water exposure, it peaks in summer and among children who swim often — which is exactly why a prevention routine matters for active swimmers.

The good news is that swimmer's ear is highly preventable, and preventing it protects something bigger than a comfortable ear: it protects your child's consistent swim lessons. Formal lessons are one of the strongest layers of protection against drowning, and every week a child sits out with a sore ear is a week of skill-building lost. Keeping ears healthy keeps kids in the water, learning to be safe.

✅ The after-swim routine: drain, dry, protect

The single most effective habit is drying the ear canal after every swim, because dry ears don't grow the bacteria that cause the infection. As soon as your child is out of the water, have them tilt their head to one side and then the other to let trapped water drain, tugging the earlobe gently to help it along. Dry the outer ear with a soft towel, and for kids prone to swimmer's ear, a hair dryer set to its lowest, coolest setting and held about a foot from the ear can evaporate the last of the moisture. Make it the same routine every time — pool day, lake day, or bath — so it becomes automatic.

One rule matters above all: never push cotton swabs, fingers, hairpins, or other objects into the ear canal. They scratch the delicate skin and strip away the earwax that naturally protects it, both of which make infection more likely, not less. Earwax is the ear's own defense; the goal is to dry the canal, not to clean inside it. If wax ever seems to be a problem, ask your pediatrician rather than digging it out at home.

🏊 Extra protection for frequent and prone swimmers

Children who swim several times a week or who keep getting swimmer's ear can add a physical barrier to keep water out. Well-fitting swim earplugs designed for the job, or a swim cap that covers the ears, both cut down how much water enters the canal in the first place. A pediatrician may also recommend an over-the-counter drying drop (often an alcohol-and-vinegar mix) to use after swimming — but only for children without ear tubes or a history of a perforated eardrum, so always check first. Pack the earplugs and a small towel in the swim bag so the whole routine travels with your swimmer.

Good pool habits help, too. Swimmer's ear is more likely after time in water that isn't well maintained, so choosing programs and pools that keep chlorine and pH in the right range lowers the risk — our guide to public pool hygiene covers what a clean, safe pool looks like. And if your child wears goggles, a snug fit means less rubbing and fussing that tempts kids to poke at their ears and eyes afterward.

🚨 Warning signs: when to stop swimming and see a doctor

Catching swimmer's ear early keeps it minor, so know the signs. It often starts with itching inside the ear, mild redness, and discomfort that gets worse when you tug the earlobe or press near the ear. As it develops, a child may complain of stronger ear pain, a plugged or muffled-hearing feeling, or clear-to-pus-like drainage. If you see any of these — especially pain, drainage, or reduced hearing — keep your child out of the water and see a doctor. Swimmer's ear is treated with prescription ear drops and usually clears quickly once treatment starts.

Some symptoms mean call the doctor promptly: fever, severe pain, swelling or redness spreading around the ear, or pain moving toward the face or neck. This checklist is educational and doesn't replace medical care — when in doubt, a quick call to your pediatrician is always the right move. Preventing the infection in the first place, though, keeps most kids out of the doctor's office entirely and in the pool where they're building lifesaving skills.
