Have you wondered what earwax is for, why we have it, and what to do if it’s excessive?
Key Functions of Earwax
Protection: It forms a waterproof lining and traps dust, debris, and microorganisms to prevent infection.
Self-Cleaning: As skin cells in the canal move outward, they carry the wax and trapped particles toward the ear opening.
Lubrication: It prevents the delicate skin of the ear canal from becoming dry, itchy, or irritated.
Antimicrobial: Earwax is slightly acidic and contains proteins that fight off bacteria.
Types and Genetics
Your earwax type is genetically determined by the ABCC11 gene:
Wet Earwax: Sticky and yellow to brown. This is a dominant trait common in people of European and African descent.
Dry Earwax: Flaky, brittle, and gray to tan. This is a recessive trait common in people of East Asian and Indigenous descent.
Why You Should Avoid Cotton Swabs!
The most common cause of earwax blockage (impaction) is the use of cotton swabs. Instead of cleaning, swabs often:
👂🏻 Push wax deeper into the ear canal where it can’t naturally escape.
👂🏻 Risk puncturing the eardrum or scratching the delicate canal wall, leading to infection.
👂🏻 Disrupt the natural movement of tiny hairs that help move wax out.
It’s best to have your Audiologist or Doctor let you know if your earwax is excessive and advise you of the best way to clear it out, if required! Too often we see patients who assumed they must have a lot of earwax, and inadvertently irritate their ear canals with invasive measures. This can be dangerous when done improperly!
Remember: Everyone should have a ‘healthy and normal amount’ of earwax and it is NOT typically an indication of poor hygiene!
