What does earwax do for your ear?

Have you ever noticed the thin layer of sticky, oily stuff inside your ears? It’s called earwax! It’s definitely not the kind of wax you use to make candles or crayons, so what do our ears need it for? We asked pediatrician Dr. Anjuli Gans to help us find the answer. Got a question that you want us to hear ? Send it to us at BrainsOn.org/contact , and we’ll wax poetic about the answer. See omnystudio.com/listener for privacy information.
