Surfer's ear, or exostosis, occurs when bone growth forms in the ear canal. This growth is the body's response to repeated exposure to wind and water. The bone thickens and causes the ear canal to narrow, which can lead to frequent ear infections, partial hearing loss, and in severe cases, complete blockage of the ear canal. That's no small matter!
Swimmer's ear is another condition that water sports enthusiasts often experience. In this case, you regularly get ear infections due to water entering your ear. In both cases, earplugs are an excellent solution.
