Why removal of wax layer too often will raise incidence of ear infection?

Removing the wax layer too frequently can increase the risk of ear infections because earwax, or cerumen, serves as a natural protective barrier. It traps dust, debris, and microorganisms, preventing them from entering the ear canal. Over-cleaning can disrupt this barrier, leading to dryness, irritation, and an increased likelihood of bacterial or fungal infections. Additionally, excessive cleaning can cause microtears in the skin of the ear canal, further heightening the risk of infection.
