Summer in Evanston means one thing for a lot of families: getting in the water. Whether you're swimming laps at Robert Crown, spending afternoons at Lighthouse Beach, or cooling off in a backyard pool, all that time in the water puts your ears at risk. Swimmer's ear is one of the most common reasons people call us this time of year, and most cases are completely preventable.

Why Swimming Season Is Hard on Your Ears

Water trapped in your ear canal creates the perfect conditions for bacteria and fungus to grow. It doesn't take a full day at the beach to cause a problem either. A week of daily swimming combined with summer humidity is often enough to trigger an infection.

Kids tend to get swimmer's ear more often because their ear canals are smaller and don't drain as well. However, adults, especially lap swimmers and triathletes, deal with it too. Symptoms usually start small: mild itching, a little soreness when you tug on your earlobe. But things can escalate quickly into redness, swelling, drainage, and pain that worsens at night. If your ear feels clogged or your hearing sounds muffled after a stretch of pool time, don't ignore it.

Lake Michigan vs. Pool Water

A lot of people assume chlorine solves everything. Unfortunately, it doesn't. Chlorine kills many bacteria, but not all of them; furthermore, it can't address what happens after you climb out of the pool. Water that stays trapped in your ear canal keeps the infection risk alive long after your swim ends.

Lake Michigan is a different story entirely. Natural bodies of water carry bacteria that pools don't, and Evanston's beaches, Lighthouse and Clark Street among them, see heavy foot traffic all summer long. Neither type of water is off-limits, but both require you to take the drying-out step seriously.

After every swim, tilt your head to each side to let water drain. Gently pull your earlobe to help straighten the ear canal. Use a soft towel corner to dry the outer ear. And skip the cotton swabs, as they push debris further in and can irritate the skin inside the canal.

When Store-Bought Drops Aren't Enough

Over-the-counter swimmer's ear drops work reasonably well for casual, occasional swimmers. If you're in the water a few times a week during vacation or a long weekend, they're probably fine. But if you're swimming daily (training for a race, doing morning laps, or managing a household of kids who practically live at the pool), drops often can't keep up.

That's where custom swim plugs make a real difference. Unlike foam or silicone plugs from the drugstore, custom plugs are molded to the exact shape of your ear canal. They seal out water completely rather than just slowing how much gets in, and they stay in place during actual swimming instead of working loose mid-stroke. For anyone who's dealt with swimmer's ear more than once, that's a meaningful upgrade.

Signs You Shouldn't Wait Out

Mild irritation often clears up on its own with a few dry days out of the water. But some symptoms mean it's time to come in and get checked:

  • Pain that's sharp or getting worse rather than better
  • Visible swelling or a canal that feels completely blocked
  • Drainage, especially if it's yellow or has an odor
  • Muffled hearing that doesn't resolve after a few days
  • Fever along with ear pain

Left untreated, swimmer's ear can spread and become far more uncomfortable and complicated to treat. Catching it early almost always means a quicker, simpler recovery.

How to Stay Ahead of the Problem

Prevention really comes down to two habits: dry your ears thoroughly after every swim, and use the right protection if you're in the water frequently.

For most casual swimmers, that means paying attention to the drying routine and keeping drugstore drops on hand. For serious swimmers or anyone with a history of recurring infections, custom plugs are worth the investment. You'll spend far less time dealing with pain, appointments, and time out of the water.

Get Fitted Before Summer Slips Away

We fit custom swim plugs year-round, but summer is when most people finally decide it's worth doing. If you're swimming in Lake Michigan or the pool almost every day, or if swimmer's ear has already found you once this season, let's get your ears protected before it happens again.
