Why do ears have ear wax?

Earwax performs important functions.
  • Your ear produces wax in order to help move out dust and other small particles. It collects dirt and debris in your ear canal and moves it out of your ears where you can wash it off as you wash your face and external ears. Cerumen also helps prevent foreign substances from entering the auditory canal.

  • It forms a layer of protective wax in the ear canal which is a water repelling shield (ear canals need to be dry to be healthy).

  • The wax also is slightly acidic and will not allow the growth of bacteria or fungi.

  • It fights infections as well, with some mild antibacterial components.
