Unfortunately for keen surfers, prolonged exposure to cool ocean water can lead to exostosis, also known as surfer's ear. Surfer's ear is a serious condition that occurs when prolonged exposure to cool or cold water causes bones to grow abnormally within the ear. These growths can lead to wax build-up and infections, which can cause hearing loss.
Ear plugs for surfers create a waterproof seal that prevents your ears from coming into contact with water, removing the conditions that enable the development of the surfer's ear.
