Introduction
Earwax has a terrible reputation. Most people see it as something dirty, unnecessary, or embarrassing—something that needs to be removed as quickly as possible. But the truth is, earwax (also known as cerumen) plays an important and protective role in keeping your ears healthy.
What Is Earwax and Why Do We Have It?
Earwax is a natural substance produced by glands in the ear canal. It may not look appealing, but it’s one of your ear’s built-in defence systems.
Healthy earwax helps to:
- Trap dust, dirt, and debris before it reaches the eardrum
- Protect the ear canal from bacteria and fungi
- Keep the ear canal moisturised and prevent dryness or itching
- Reduce irritation from water and environmental exposure
In a healthy ear, earwax moves outward naturally and falls away on its own—no cleaning required.
How Earwax Normally Cleans Itself
The ear’s self-cleaning mechanism is one of the body’s quieter marvels. As skin inside the ear canal naturally migrates outward, it carries old earwax along with it. This slow process happens continuously, without us ever noticing.
Interfering with this mechanism — especially by inserting objects into the ear — disrupts the outward movement and pushes wax back in. Over time, this creates a cycle where the ear produces more wax in response to irritation, increasing the likelihood of blockage.
Signs and Symptoms of Earwax Impaction
One of the reasons earwax impaction is so often overlooked is that its symptoms can resemble other ear conditions. Many patients assume they have an infection or age-related hearing loss when the issue is actually mechanical blockage.
In some cases, impacted earwax can even affect the vagus nerve, which runs through the ear canal. This can explain why certain people experience coughing or throat irritation when their ears are blocked — a surprising but clinically recognised connection.
Common signs include:
- A blocked or full sensation in the ear
- Reduced or muffled hearing
- Ringing or buzzing in the ear (tinnitus)
- Earache or discomfort
- Dizziness or balance issues
- Coughing triggered by ear canal stimulation
If symptoms appear suddenly or worsen after using cotton swabs, earwax is often the culprit.
Why Cotton Swabs Are a Bad Idea
Cotton swabs give the illusion of cleanliness. While they may remove wax from the outer ear, they simultaneously force wax deeper into the canal, where it becomes compacted and difficult to remove naturally.
Repeated cotton swab use also strips away protective oils, leaving the ear canal dry and itchy. This dryness often prompts even more cleaning, creating a self-perpetuating cycle that increases irritation and wax production rather than reducing it.

Common Home Remedies That Do More Harm Than Good
Many home remedies are appealing because they seem simple, inexpensive, and “natural.” Unfortunately, the ear canal is not designed for experimentation. Introducing substances or pressure without visibility increases the risk of injury.
Ear candling, in particular, has been shown to be ineffective and potentially dangerous. Not only does it fail to remove wax, but it also poses a burn risk and can leave candle residue inside the ear — a problem audiologists see far too often.
Hearing loss linked to diabetes often develops gradually, making it easy to miss. Many people unconsciously adapt, delaying diagnosis and treatment.
- Ear candling
- Pouring oils or hydrogen peroxide without guidance
- Using hairpins, keys, or tissues
- Flushing ears with water at home
- Repeated over-the-counter drops without assessment
Earwax, Hearing Loss, and Hearing Aids
Impacted earwax is one of the most common reasons hearing aids are thought to be “failing.” In many cases, the device itself is working perfectly — it’s simply blocked by wax in the ear canal or the hearing aid receiver.
Removing earwax before hearing tests is equally important. Blockage can artificially worsen test results, leading to incorrect diagnoses or inappropriate treatment recommendations.
How Often Should You Clean Your Ears?
Modern audiology advice is refreshingly simple: if your ears feel fine, leave them alone. Routine cleaning inside the ear canal is not only unnecessary, it’s counterproductive.
For people prone to buildup, scheduled check-ups are far safer than frequent self-cleaning. Think of ear care like dental care — prevention and professional oversight are far more effective than aggressive home maintenance.
Conclusion
Many people wait far too long before seeking professional help, often enduring weeks or months of discomfort. This delay increases frustration and can exacerbate symptoms like tinnitus or dizziness.
Seeing an audiologist early not only resolves the immediate issue but also provides reassurance, education, and guidance tailored to your ears — something no online remedy can offer.
Frequently Asked Questions
1: Can diabetes cause permanent hearing loss?
Yes. Damage to nerves and blood vessels in the inner ear can become permanent if unmanaged.
2: Is hearing loss more common in Type 2 diabetes?
Both types increase risk, but Type 2 diabetes is more common overall.
3: Should people with diabetes get routine hearing tests?
Yes. Regular assessments are strongly recommended.
4: Can blood sugar control improve hearing?
It may slow progression and protect remaining hearing, even if damage can’t be reversed.It may slow progression and protect remaining hearing, even if damage can’t be reversed.
5: Are balance problems linked to diabetes too?
Yes. The inner ear affects both hearing and balance.
