Excess ear wax is almost always the result of your body doing its job a little too enthusiastically. Ear wax is a natural protective substance, and some people simply produce more of it due to genetics, habits, or the shape of their ear canals. The good news: overproduction itself isn’t dangerous, though buildup can cause uncomfortable symptoms if wax gets trapped.
How Your Ears Make Wax
Two types of glands line your ear canal and work together to produce wax. Sebaceous glands, attached to tiny hair follicles, secrete an oily substance called sebum that keeps the skin inside your ears from drying out. Ceruminous glands, which are modified sweat glands, add antimicrobial proteins that fight off germs. These secretions mix with dead skin cells and hair to form what you see on the end of a cotton swab.
Under normal conditions, your ears clean themselves. Jaw movements from chewing and talking slowly push old wax toward the opening of the ear canal, where it dries up and falls out. When something disrupts that conveyor belt, or when the glands produce more than the system can clear, wax builds up.
Genetics Play a Bigger Role Than You’d Think
Your genes determine not just how much wax you produce but what type. A single gene called ABCC11 controls whether you have wet or dry ear wax. Wet wax is sticky, honey-colored, and contains more oily secretions. Dry wax is flaky, pale, and lighter. The wet type is far more common in people of European and African descent, while the dry type is nearly universal in people of East Asian heritage, particularly those with northern Chinese or Korean ancestry.
If you have the wet type, your glands are naturally producing more sebum in the ear canal, which means a higher baseline volume of wax. People with wet wax are also more susceptible to increases in production from dietary and environmental triggers.
Common Habits That Increase Wax
Cotton swabs are the biggest culprit, and the irony is hard to miss: the tool most people use to remove wax actually stimulates the ear to make more of it. When you push a swab into your ear canal, it stimulates the tiny hairs lining the walls. Those hairs send signals to your glands to ramp up production. On top of that, swabs push existing wax deeper, packing it against the eardrum instead of letting it migrate out naturally.
Earbuds and headphones create a similar problem. If you wear them for hours every day, they physically block the self-cleaning process and can irritate the skin and cartilage of the outer ear canal. That irritation can trigger even more wax as your body tries to protect the area. Hearing aids have the same effect, which partly explains why wax impaction is found in up to 57% of older adults in nursing care.
Diet and Lifestyle Factors
The link between diet and ear wax isn’t backed by rigorous clinical studies, but the biological mechanisms are plausible. Foods high in fat can increase sebum production throughout your body, including in the ear canal. Since sebum is a primary ingredient in ear wax, more sebum means more wax. High-sugar foods may have a similar effect by triggering insulin release, which can stimulate the sebaceous glands.
Spicy foods contain capsaicin, which stimulates both sweat and oil glands and temporarily widens blood vessels, increasing gland secretions as the body tries to cool down. Caffeine activates the sympathetic nervous system (your “fight or flight” response), which also stimulates oil glands. Alcohol dehydrates the body and widens blood vessels at the same time, prompting the ear canal to secrete more moisture. Even a high-sodium diet can make wax stickier through fluid retention, making it more prone to blockages. If you’ve noticed changes in your ear wax after shifting your diet, these mechanisms may explain why.
Skin Conditions and Ear Canal Shape
Eczema and psoriasis can both affect the ear canal and dramatically increase the amount of debris inside it. Psoriasis causes thick, scaly patches of dead skin that can flake off and fall into the ear canal, mixing with wax and creating blockages. Sebopsoriasis, a related condition, produces greasy bumps and yellow plaques that add oily material to the mix. Eczema causes dry skin and small bumps that shed extra skin cells into the canal. If you have either condition elsewhere on your body and notice excessive ear wax, your ears may be affected too.
The physical shape of your ear canal matters as well. Narrow or unusually curved canals make it harder for wax to travel outward on its own, so even a normal amount of production can result in buildup. People with a lot of ear hair experience this too, since hair can trap wax before it reaches the opening.
Age Changes How Wax Behaves
As you get older, the glands in your ear canal change. They produce drier, harder wax that doesn’t move through the canal as easily. Your ears lose some of their ability to self-clean, and wax is more likely to accumulate and harden into a plug. This is a major reason wax impaction rates climb with age. About 5% of healthy adults have impacted wax at any given time, but that number jumps significantly in older populations.
Impacted wax in older adults isn’t just an annoyance. It can cause reversible hearing loss, and that hearing loss has been linked to cognitive changes that improve once the wax is removed. Tinnitus (ringing in the ears), a feeling of fullness, ear pain, itching, and occasionally dizziness or a persistent cough can all result from a wax blockage pressing against the eardrum or the nerve-rich walls of the ear canal.
Safe Ways to Manage Excess Wax
The most important guideline, reinforced by the American Academy of Otolaryngology, is to stop putting anything in your ear canal. No cotton swabs, no bobby pins, no twisted tissue corners. These all push wax deeper and stimulate more production. Ear candling, which involves placing a hollow lit candle in the ear, has never been shown to work and carries real risks of burns and ear canal damage.
If wax isn’t causing symptoms, you don’t need to remove it at all. Wax is protective, and having visible wax in your ears is normal, not a hygiene failure. When it does cause problems like muffled hearing or discomfort, a few drops of plain water, saline, or an over-the-counter softening drop can help loosen the plug so it migrates out on its own. You can also try gentle irrigation with a bulb syringe and warm water, though this carries a small risk of skin irritation or dizziness if the water is too cold or too forceful.
For stubborn impactions, a healthcare provider can remove wax manually with specialized tools or professional-grade irrigation. This is especially worth considering if you have ear tubes, a history of ear surgery, or a perforated eardrum, since home irrigation can cause harm in those situations. If you find yourself dealing with blockages repeatedly, the underlying cause is worth investigating, whether that’s a skin condition, earbud habits, or simply the genetics of your ear canal.
