Your ears may be producing more wax than usual because of something blocking its natural exit path, changes in gland activity triggered by stress, or simply your genetics. Nearly 1 in 5 people over age 12 have enough wax buildup to cause a blockage, and that number climbs to about 1 in 3 for adults over 70. In most cases, the issue isn’t that your ears are broken. They’re doing exactly what they’re designed to do, just a bit too enthusiastically or without enough help clearing things out.
What Earwax Actually Does
Earwax is produced by two types of glands in the skin of your ear canal: modified sweat glands (called ceruminous glands) and oil-producing glands (sebaceous glands). Together, they create a sticky substance that traps dust, dead skin cells, and debris before they reach your eardrum. It also contains a surprising cocktail of antimicrobial compounds, including proteins that fight bacteria and fungi. Earwax is essentially a self-cleaning, self-defending system built into your ear canal.
Under normal circumstances, your ears push old wax outward on their own. Jaw movement from chewing and talking helps, and the skin inside the ear canal slowly migrates toward the opening, carrying wax along with it. When this conveyor belt works properly, you never notice it. Problems start when production outpaces removal, or when something jams the system.
Headphones and Hearing Aids Block the Exit
One of the most common reasons for noticeable wax buildup is spending hours with something lodged in your ear canal. Earbuds, in-ear headphones, hearing aids, and even earplugs physically block the natural cleaning process. Wax that would normally work its way out gets pushed back in or simply has nowhere to go. These devices can also irritate the skin and cartilage of the outer ear canal, which may stimulate the glands to produce even more wax in response.
If you wear earbuds for most of the day, whether for work calls, music, or podcasts, this is one of the first things worth examining. Switching to over-ear headphones, taking breaks, or gently wiping the outer ear canal after removing your earbuds can make a real difference.
Stress Can Ramp Up Production
Your ceruminous glands are modified sweat glands, and they respond to the same signals. When you’re anxious or stressed, your body ramps up cortisol production, and that can cause earwax output to increase in much the same way stress makes your forehead or armpits sweat. If you’ve noticed your ears feel more clogged during high-pressure periods at work or during times of persistent anxiety, the connection is real and physiological, not imagined.
Genetics Play a Bigger Role Than You’d Expect
The type and amount of earwax you produce is heavily influenced by a single gene called ABCC11. This gene comes in two variants that determine whether your earwax is wet and sticky or dry and flaky. People of East Asian descent carry the dry-type variant at very high rates (80 to 95%), while people of European and African descent almost universally produce the wet, yellow, sticky type.
Wet earwax tends to accumulate more noticeably. If your parents dealt with heavy wax buildup, you likely will too. This isn’t something you can change, but knowing it helps you understand that your ears aren’t malfunctioning. They’re just following a genetic blueprint that calls for more output.
Aging Changes the Texture
As you get older, the glands inside your ear canal start producing drier, harder wax. This matters because dry wax doesn’t slide out of the ear canal as easily as the softer kind. The natural self-cleaning mechanism becomes less effective, and wax starts to accumulate and compact. This is a major reason why earwax impaction affects roughly a third of adults over 70, nearly double the rate of the general population. If you’ve noticed more wax problems as you’ve gotten older, this shift in consistency is the likely explanation.
Skin Conditions and Ear Canal Shape
Certain skin conditions can change the environment inside your ear canal in ways that increase wax production or make it harder to clear. Eczema and psoriasis can cause flaking and inflammation in the ear canal, mixing with wax and creating thicker, more stubborn buildup. The irritated skin may also trigger the glands to produce more wax as a protective response.
The physical shape of your ear canal matters too. Some people have narrower or more curved canals that naturally trap wax more easily. You can’t see this yourself, but if you’ve always struggled with wax despite not using earbuds or doing anything that should cause buildup, anatomy is a reasonable explanation.
Cotton Swabs Make Things Worse
If your response to extra wax has been reaching for a cotton swab, you’re likely compounding the problem. Swabs push wax deeper into the ear canal, past the point where the natural cleaning mechanism can reach it. Over time, this creates a compressed plug right against the eardrum. The glands keep producing wax on the outer portion of the canal, but now there’s a dam blocking everything from moving outward. This is one of the most common causes of impaction, and it creates a frustrating cycle: more wax visible at the opening leads to more swabbing, which pushes more wax deeper.
Signs That Wax Has Become a Problem
Extra wax production on its own isn’t harmful. The trouble starts when wax accumulates enough to form a blockage. Common signs include a feeling of fullness or pressure in the ear, muffled hearing, ringing (tinnitus), itchiness, or dizziness. These symptoms can come on gradually, making them easy to dismiss until they become significant.
Certain signs point to something more than simple wax buildup. Ear pain that persists, drainage leaking from the ear, a foul smell, or fever suggest a possible infection rather than just impaction. Green, yellow, white, or black-colored discharge also warrants prompt attention from a healthcare provider.
Safe Ways to Manage Excess Wax
For most people, the best approach is helping the natural process along rather than fighting it. A few drops of mineral oil, baby oil, or over-the-counter ear drops can soften hardened wax enough for it to work its way out on its own over a few days. Letting warm water gently rinse the outer ear during a shower helps too.
If you’re dealing with a full blockage, especially one causing hearing changes or discomfort, professional removal is the safest option. A clinician can clear impacted wax in minutes using irrigation or specialized instruments, with minimal discomfort. People who are prone to recurrent buildup often benefit from scheduling routine cleanings every 6 to 12 months rather than waiting for symptoms to return. If you wear hearing aids, your audiologist can check for wax buildup at regular appointments and stay ahead of the cycle.
