Why Earwax Builds Up—and How It Can Affect Daily Life
Earwax (cerumen) is normal and useful. It protects the ear canal by trapping dust and debris and helping prevent irritation and infection. Problems occur when too much accumulates or becomes impacted.
Why does earwax build up?
Common reasons include:
- Naturally producing a lot of wax
- Ear canals that are narrow or unusually shaped
- Using cotton swabs or other objects in the ear, which can push wax deeper
- Hearing aids or earbuds, which can interfere with normal wax movement
- Changes in the skin of the ear canal as we age
What symptoms can it cause?
Impacted wax may cause:
- Muffled or reduced hearing
- A feeling of fullness or blockage
- Earache or discomfort
- Ringing in the ear (tinnitus)
- Itching
- Occasionally, dizziness or balance problems
Even mild hearing reduction can make conversations, television, or phone calls more difficult and can affect everyday communication.
🛑 Don’t dig it out
Avoid putting cotton swabs, hairpins, keys, or other objects into the ear canal. They can push wax farther in or injure the eardrum.
For straightforward earwax blockage, healthcare professionals may recommend wax-softening drops and, when appropriate, removal by irrigation or a trained professional. However, people with a perforated eardrum, previous ear surgery, ear tubes, or significant ear pain/discharge should get medical advice before using drops or attempting removal.
