Outer ear infections: How to prevent them in summer and when to see a doctor
Article07. 07. 2025
Outer ear infections (otitis externa) are a common issue during the summer months, often affecting both children and adults after swimming in pools, lakes, or the sea. Fortunately, there are effective ways to prevent these unpleasant problems.
The most common causes of summer ear infections
“Water, sand, or other debris can easily enter the ear canal while swimming. The moist environment then encourages bacterial growth, which can lead to a painful infection,” explains Dr. Barbora Hradecká, Head of ENT at Canadian Medical. Risk factors include frequent diving and prolonged exposure to chlorinated water, which can irritate the delicate skin of the ear canal.
How to clean your ears properly
A very common myth is the use of cotton swabs. “Never insert anything into the ear canal. Cotton swabs often push earwax deeper or can injure the delicate skin and eardrum,” warns Dr. Hradecká. The ear has a natural self-cleaning mechanism. Simply wipe the outer part of the ear with a soft towel after showering or swimming. If you feel your ear needs cleaning, consult an ENT specialist.
How is it treated and when should you see a doctor?
If an infection occurs, it is usually treated with local ear drops or sprays. “Treatment is generally simple if started early,” adds Dr. Hradecká. At the first signs—such as pain, a feeling of fullness, or itching—you can try over-the-counter products from the pharmacy. However, if symptoms worsen, persist for more than two days, or if there is discharge from the ear, it is essential to see an ENT specialist.
Prevention is key
To prevent infections, avoid unnecessary wetting of the ears, gently dry them after swimming, and use earplugs when diving. Proper care is the simplest way to enjoy summer without health complications.
