Ear wax is produced by glands in the ear canal. Ear wax has a few purposes, although scientists are unsure of the complete reason that ear wax is produced by the human body.
Ear wax is believed to help prevent dirt, dust and other small debris from entering the inner ear canal and potentially damaging or infecting the eardrum. This small debris is caught in the ear wax and is removed as the wax hardens and is pushed or falls out of the ear. Ear wax can vary depending on genetics; however, all humans naturally make it. Oddly shaped ear canals can cause ear problems due to the inability for the ear to naturally push the wax out.
