Regular surfers and swimmers in the sea are prone to developing cranial exostoses; surfers' ear. The evaporative cooling effect of wind and sea water causes bony outgrowths to form around the opening of the ear canal.
The canal gradually closes up over the course of years. When the canal is about 90% closed the surfer notices that they are going deaf; this is often the first sign of the problem.
This occurs due to the cooling of the skin of the ear by the breeze and the sea water causing the bone to over-grow. The bony growths stop the sound waves reaching the eardrum, resulting in what is known as conductive deafness.
Surfers can prevent surfers' ear by wearing a good pair of surfers' ear plugs. These ear plugs from ZenPlugs are ideal because they are antibacterial and can be connected on a cord so you don't lose them.
Surfers' ear also causes repeated ear infections. This is because the ear canal retains debris and water creating an ideal breeding ground for bacteria and fungi. Ear plugs from ZenPlugs are ideal at preventing surfers' ear because they are waterproof and non-porous. This keeps out the cooling effect of the wind and waves. They also help to prevent the repeated ear infections. This is by including a highly effective antibacterial called Steritouch. It destroys all the bugs which cause ear infections.
