Swimmers' ear

As it’s name suggests, swimmer’s ear often develops after swimming in contaminated water, but may also occur any time that water becomes trapped in the ear canal, creating an environment that’s hospitable for bacteria to multiply in.

This is more likely to occur if:

• The ear canal is obstructed for some reason (e.g. an excess of earwax)
• Too little earwax is present, which may be a consequence of spending a large amount of time in water
• The tissues of the ear are damaged (e.g. from wearing a hearing aid or ear plugs, or from using cotton buds to clear the ear of wax)
• The acidity of the ear canal is altered

The functions of earwax include inhibiting the proliferation of infectious organisms and maintaining the health of the surfaces of the inner ear, so its presence in appropriate quantities is a vital part of the body’s defences against ear infection.

People who have allergies (for example, asthma, dermatitis or hay fever) are more likely to develop swimmer’s ear than other people, as are those with diabetes and some other chronic illnesses.

The bacteria most commonly responsible for the infection are Staphylococcus aureus and Pseudomonas aeruginosa, but fungal organisms of the Aspergillus and Candida species may also be involved.

• Echinacea helps support the immune system and may assist your body in fighting infections; the antioxidant nutrients betacarotene, vitamins C and E and the minerals zinc and selenium may also be of assistance.
• Garlic has traditionally been used to help the body fight infections, and displays antimicrobial activity against a wide range of infectious organisms, including species of Staphylococcus, Aspergillus and Candida. It is often taken with echinacea for additional immune support.
  

• Don’t allow the ear to get wet when you have swimmer’s ear. You may need to wear a shower cap when bathing and avoid swimming until the infection is resolved. If you do go swimming, take care to keep your head above water.
• Don't swim in polluted water.
• Clear the water from your ears after swimming or bathing.
• Don’t use cotton buds or other items to clear wax from your ears.
• Don’t use soap to wash out the ears, as this can alter the pH of the canal, predisposing you to infection.
• Prevent swimmers' ear by using eardrops immediately after swimming to dry and disinfect the ear canal.
• Prevent damage to the ear by avoiding the use of earplugs. Ensure any hearing aid you wear fits well.
  

• Serious consequences can arise from untreated ear infections, so it’s important that you consult your health care professional if you or your child are displaying symptoms of infection or develop hearing problems.
