Many people think it is just trapped water.
But sometimes, that moisture inside the ear can create the perfect environment for bacteria and fungi to grow.
This condition is known as Swimmer’s Ear, medically called Otitis Externa.
What Is Swimmer’s Ear?
Swimmer’s ear is a bacterial or fungal infection of the ear canal.
Normally, ear wax helps protect the ear from germs and moisture.
But when water remains trapped inside the ear for long periods:
• the skin becomes soft,
• the protective barrier weakens,
• and microorganisms can easily grow.
That is why people who swim frequently are more prone to this condition.
Why Does It Happen More in Swimmers?
Most bacteria and fungi thrive in:
• warm environments,
• humid conditions,
• and moisture-rich areas.
Swimming pools, repeated water exposure, and poor ear drying habits create an ideal environment for infection.
Common organisms involved include:
• Pseudomonas aeruginosa
• Staphylococcus aureus
• Fungi like Candida and Aspergillus
Since it is commonly seen in avid swimmers, it is called “Swimmer’s Ear.”
Symptoms and Signs
Usually, symptoms starts with mild redness, ear itching, feeling of fullness to increase in pain, fluid discharge and swelling of ear canal.
In more advanced stage, fever, pus discharge, infection spreading beyond the ear is also seen.
Risk Factors
Certain habits and conditions increase the risk of swimmer’s ear.
• Frequent swimming
• Humid climate
• Using cotton buds aggressively
• Scratching inside the ear
• Earphones or hearing aids for long duration
• Excess moisture inside ears
• Skin conditions like eczema
Diagnosis
Doctors usually diagnose swimmer’s ear through:
• Physical examination of the ear canal
• Checking redness, swelling, or discharge
• Sometimes laboratory testing if fungal infection is suspected
Treatment and Medication
• Antibiotic ear drops
• Antifungal ear drops
• Pain relief medications
• Cleaning of ear canal by doctor
Prevention
• Dry ears gently after swimming
• Tilt the head to remove trapped water
• Avoid inserting sharp objects into ears
• Use ear plugs while swimming if advised
• Avoid prolonged moisture inside the ear
• Keep swimming equipment clean
We often think infections come only from "dirty places."But sometimes, even clean water trapped in the wrong place for too long can create problems.
