What the CERUMEN does inside your EAR and why it's not "dirt"
For years, wax has been perceived as something that should be eliminated completely. However, from a medical point of view, it is one of the most effective protective mechanisms of the ear duct. It's not a useless waste, but a substance designed to preserve ear health.
Cerumen is a mixture of secretions of specialized glands, decayed cells, and lipids. This combination creates a slightly acidic substance that lubricates the skin of the ear canal and prevents it from drying or cracking. Intact skin is the first barrier to infections.
Also, the wax acts as a physical filter. It traps dust, environmental particles, and microorganisms before they can reach deeper structures. Its chemical composition hinders the growth of bacteria and fungi, reducing the risk of infections like external otitis.
The hearing canal has a natural self-cleaning mechanism. The skin covering it slowly migrates outward, pushing the serum down gradually. Jaw movements when talking or chewing facilitate this displacement. When the wax reaches the visible part of the earphone pavilion, it can be gently removed with a wet cloth. No object needed to be introduced.
When hysops or other instruments are placed inside the ear, the opposite effect occurs than expected. Instead of extracting the wax, it usually pushes itself to the bottom, compacting it against the earbud. This favors the formation of plugs, feeling of blocked ear, and decreased hearing. In addition, the skin of the canal is delicate and can be easily injured, increasing the risk of infection or even tympanic perforation.
In some cases, the production of serum is higher or its consistency is thicker, which can lead to obstruction. When symptoms such as pain, buzzing, pressure sensation or hearing loss appear, medical evaluation allows for safe removal.
Bottom line, wax is not dirt that should be removed altogether. It is a protective substance that lubricates, cleanses, and defends the ear against infections. The best way to care for hearing is not to intervene constantly, but to respect the natural protective mechanism that the organism itself has developed.
