Although swimmer’s ear cannot always be prevented, people can take several steps to reduce their likelihood of contracting this infection. Drying the ears after swimming or bathing is crucial to reducing the risk of swimmer’s ear. Some experts have recommended using a hair dryer to dry the ear canal. It may also help to use an alcohol-based ear product that will dry out the ear. Such products can be found in pharmacies. Patients should consult their physician about whether these products are right for them, and whether a homemade solution may be used.

Swimming in pools and hot tubs with good chlorine and pH control can also significantly reduce the risk of contracting swimmer’s ear. It is also important not to swim in an area that has been closed due to pollution. Using earplugs during swimming can help prevent water from getting in the ear canal. Using oil or lanolin eardrops in the ears prior to swimming can also protect against the effects of water.

People are urged to take steps to prevent irritating substances from entering the ear canal. For example, it may be helpful to place cotton balls in the ears when applying sprays or dyes to the hair. Patients may also be advised to avoid frequent washing of the ear canal with soap, which can upset the acid balance of the canal lining and promote infection.
