What Is Ear wax? Ear wax, scientifically known as cerumen, is a natural substance produced by the ear canal's ceruminous glands. Its presence serves several important purposes within the ear: Protection: Ear wax acts as a protective barrier, shielding the delicate and sensitive ear canal skin from external elements such as dust, debris, insects, and water. This protective function helps prevent potential infections and irritations. Moisturisation: Ear wax helps keep the ear canal skin moisturised, preventing it from becoming dry and prone to itching or discomfort. Self-Cleaning Mechanism: The ear canal is not a straight pathway; it curves and moves in a circular motion. As new ear wax is produced, it gradually moves from the deeper parts of the ear canal toward the outer ear. In this process, old earwax, along with trapped debris, dust, and dead skin cells, is naturally pushed out of the ear, aiding in the self-cleaning of the ear canal. Infection Prevention: The slightly acidic nature of ear wax helps create an environment that is inhospitable to bacteria and fungi, reducing the risk of infections. Protection from Noise and Insects: Ear wax can also help prevent certain insects from entering the ear canal, and in some cases, it can act as a natural defense against loud noises by absorbing some of the sound energy before it reaches the delicate structures of the inner ear. While ear wax serves these beneficial functions, sometimes it can accumulate and become impacted, leading to hearing problems, discomfort, or an increased risk of infection. Regular maintenance and, if necessary, professional removal, can help ensure that ear wax continues to fulfill its protective role without causing issues.
