Swimmer’s ear (otitis externa) is the most-frequent non-injury issue in competitive youth swim. The kid finishes the meet, complains of ear pain that night, the next morning the ear is swollen and tender, and three days of practice get missed. Most cases are entirely preventable.
This is the prevention.
What swimmer’s ear actually is.
Otitis externa is an infection of the outer ear canal, typically bacterial (often Pseudomonas) but sometimes fungal. Pool water trapped in the canal creates a warm, moist environment where bacteria multiply. Different from otitis media (middle ear infection), which most parents think of when they hear “ear infection.”
The signs:
Ear pain, often starting mild and getting worse over hours.
Itching or fullness in the ear.
Tenderness when the outer ear is pulled or the area in front of the ear is pressed.
Drainage (clear, yellow, or sometimes bloody).
Hearing reduction.
Severe cases may have spreading redness, swollen lymph nodes, fever.
The prevention protocol.
The U.S. Centers for Disease Control and Prevention (CDC)‘s Healthy Swimming program and AAO’s published guidance converge on a few steps:
After every swim, dry the ears thoroughly. Tilt head to each side, allow water to drain, dry the outer ear with a towel. Most parents stop here. Most kids who get swimmer’s ear are kids who stopped here.
For kids prone to swimmer’s ear, drying drops after every swim. The standard home recipe (or commercial equivalents like Swim-EAR):
Equal parts isopropyl rubbing alcohol and white vinegar. The alcohol displaces water and dries the canal; the vinegar acidifies, making bacterial growth harder. 5 drops in each ear after every swim, head tilted, allow to drain after 30 seconds.
Commercial alternatives (Auro-Dri, Swim-EAR) are similar formulations and work equivalently for prevention.
For kids with active or recent infection, a doctor may prescribe antibiotic ear drops; do not use the alcohol/vinegar mix on a kid with active infection or with tubes in the ears (myringotomy tubes change the calculation).
Swim caps and earplugs.
A well-fitted silicone or latex swim cap that covers the ears reduces water entry to the canal. Some kids find caps over the ears uncomfortable; comfort is a real factor in whether they actually wear it.
Custom-molded earplugs (made by an audiologist or sports-medicine clinic) are the gold standard for kids with recurrent swimmer’s ear. The fit prevents water entry without restricting hearing as much as soft over-the-counter plugs.
Soft over-the-counter earplugs (Mack’s, Macks Pillow Soft) work for casual prevention but fall out more easily during fast swims.
Recurrent infections.
A kid who gets 3 or more swimmer’s ear infections in a season may need:
Audiologist consult for custom earplug fit.
Pediatrician visit to rule out underlying ear-canal anatomy issues.
Investigation of pool chlorination at the practice facility. Under-chlorinated pools have higher swimmer’s ear rates.
The “stop using cotton swabs” rule.
Cotton swabs (Q-tips) push wax deeper into the ear canal, creating a damp environment for infection. AAO is direct: do not use cotton swabs to clean the ear canal. Drying the outer ear with a towel is sufficient.
Earwax actually has antibacterial properties and is part of the canal’s natural defense. Removing wax aggressively (cotton swabs, ear candles, irrigation) increases infection risk.
When to call the pediatrician.
Pain that started mild and is now severe.
Drainage from the ear.
Fever above 101°F with ear pain.
The ear is swollen externally.
Hearing reduction that does not resolve in 24 hours.
Pain that does not respond to over-the-counter pain medication (acetaminophen, ibuprofen).
Most pediatricians will diagnose by exam and prescribe topical antibiotic drops (ofloxacin, ciprofloxacin) for 7 to 10 days. Symptoms typically improve within 48 hours of starting drops.
For competitive swim teams.
Programs that practice in poorly-maintained pools see more ear infections. Worth knowing about your pool’s chlorination and pH testing schedule. Properly chlorinated pools (1 to 3 ppm free chlorine, pH 7.2 to 7.8) support healthy swimming with minimal infection risk.
Some programs have a “drying drops” station at practice end. The kid lines up after warm-down, gets drops, leaves. Reduces team-wide infection rate.
For parents.
For the kid who has had swimmer’s ear once, set up the prevention drops habit. Cheap, fast, effective.
For the kid who has had swimmer’s ear three times in a season, see the pediatrician about custom earplugs and pool-environment factors.
For the kid currently in pain, the pediatrician same day or next morning. The infection responds quickly to topical antibiotics; it gets worse without them.
The honest read. Swimmer’s ear is one of the most-preventable youth-sport issues. The 30 seconds after every swim with drying drops eliminates the majority of cases. The kids who keep getting it are usually kids who never adopted the prevention habit. Programs that build it into the practice end-routine see fewer kids missing meets. The cost is a $5 bottle of drops per season per kid.
