Earwax, medically called cerumen, is a natural substance produced by glands in the ear canal. It protects, lubricates, and cleans the ear by trapping dust, bacteria, and other foreign particles.
Functions of Earwax
- Protection – Prevents dirt, dust, and small insects from entering the ear.
- Lubrication – Keeps the ear canal from becoming dry or itchy.
- Antimicrobial properties – Helps prevent infections.
- Cleaning – Moves naturally outward, carrying debris with it.
Types of Earwax
- Wet earwax – Sticky or waxy, common in people of European and African ancestry.
- Dry earwax – Flaky, more common in East Asian and Native American populations.
Earwax Removal
- Normally, the ear is self-cleaning. Most people do not need to remove earwax manually.
- Safe methods:
- Over-the-counter ear drops to soften wax
- Professional removal by a healthcare provider
- Avoid: Cotton swabs or sharp objects, which can push wax deeper or injure the ear.
When to Seek Medical Advice
- Hearing loss or muffled hearing
- Ear pain or discharge
- Persistent itching or ringing in the ears
- Feeling of fullness in the ear
If you want, I can also make a diagram showing how earwax forms and exits the ear naturally, which helps visualize why manual cleaning is often unnecessary.
Do you want me to make that diagram?
