Yes, swimming is the leading risk factor for developing otitis externa, which is why the condition is commonly known as swimmer ear. In 2026, clinical data continues to show a strong correlation between frequent water exposure and inflammation of the external ear canal. While the ear has natural defences to stay dry and acidic, prolonged exposure to moisture can break down these barriers, creating an ideal environment for bacteria and fungi to thrive.

The Science of Water and the Ear
1. Skin Maceration
When water stays in the ear canal for an extended period, the skin becomes waterlogged or soft. This is called maceration. Just like the skin on your fingers prunes after a long bath, the skin in your ear becomes porous and fragile, making it easy for bacteria to penetrate the surface.
2. Disruption of pH Balance
The ear canal needs to be slightly acidic to kill off pathogens. Swimming, especially in chlorinated pools or alkaline lake water, can neutralise this acidity. Once the pH shifts, the ear natural chemical shield is gone, allowing common bacteria like Pseudomonas to colonise the skin.
3. Trapped Contaminants
Water is rarely sterile. Whether it is chlorine resistant bacteria in a public pool or microorganisms in a lake, swimming introduces foreign pathogens directly into the canal. If the water does not drain out completely, these organisms stay trapped against the skin.
Risk Factors Beyond Just Getting Wet
In 2026, we recognise that some swimmers are at a much higher risk than others due to anatomical or lifestyle factors.
- Canal Shape: Men and children with narrow or particularly curvy ear canals are more likely to trap water.
- Exostoses (Surfer’s Ear): Long term exposure to cold water can cause bony growths in the canal, which act as dams that prevent water from draining.
- Skin Sensitivity: Individuals with existing eczema or psoriasis in the ear are more prone to infection because their skin barrier is already compromised.
- Aggressive Cleaning: Using cotton buds after swimming to dry the ears often does more harm than good by removing protective wax and creating micro tears in the skin.
2026 Prevention Strategies for Swimmers
If you are a regular swimmer, you do not have to accept ear infections as an inevitability. Clinical protocols in 2026 recommend the following:
- Keep it Dry: Use a hair dryer on the lowest, coolest setting held at arm length to gently dry the canals after swimming.
- The Gravity Tilt: Tilt your head to each side while pulling your earlobe in different directions to help water escape.
- Fitted Earplugs: Use high quality, silicone earplugs designed specifically for swimming to prevent water entry.
- Preventative Drops: In 2026, many clinicians recommend specialised acetic acid drops after swimming to restore the ear natural acidity and kill off trapped bacteria.
To Summarise
Swimming significantly increases the risk of otitis externa by softening the skin of the ear canal and disrupting its natural acidic protection. In 2026, we view swimmer ear as a preventable condition that relies on keeping the ears dry and maintaining the skin integrity. If you enjoy the water, being proactive about drying your ears and avoiding aggressive cleaning with cotton buds is the most effective way to stay in the pool and out of the clinic.
If you have just been swimming and your ear feels itchy or painful when touched, the next clinical step is to avoid further water exposure and consult a healthcare professional for medicated ear drops.
Is sea water safer for ears than pool water?
Not necessarily. While salt water has some antibacterial properties, it still causes skin maceration, and coastal waters can contain high levels of runoff bacteria.
Can I swim with a current ear infection?
No. In 2026, we strictly advise against swimming until the infection is completely resolved and the skin has had time to heal, usually 7 to 10 days after symptoms stop.
Do swim caps prevent swimmer’s ear?
They help, but they are not a total seal. Most caps still allow some water to seep into the canals. Combining a cap with earplugs is more effective.
Why do children get swimmer’s ear more often than adults?
Children have narrower ear canals that trap water more easily, and they are more likely to spend long periods playing in the water without drying their ears.
Can I use rubbing alcohol to dry my ears?
In 2026, we generally advise against pure rubbing alcohol as it can be too drying and cause skin cracking. A specialised ear drying solution containing a mix of alcohol and acetic acid is safer.
How do I know if the water is out of my ear?
The feeling of fullness or muffled hearing should resolve immediately once the water is gone. If the blocked feeling persists, it may be due to water trapped behind earwax or the beginning of inflammation.
