# Feeling of a blocked ear and what earwax does
Everyone knows it – suddenly you feel as if someone has pressed a mute button. Sounds come from a distance, your own voice sounds strange, and an unpleasant pressure has settled in your ear that simply won't go away. The feeling of a blocked ear is one of the most common complaints that bring people to the doctor, and although it may sound like a trivial matter, there can be a whole range of causes behind it. One of the most common – and yet most underestimated – is excessive production or accumulation of earwax.
Earwax is a substance that only gets talked about when it causes problems. Yet it is a completely natural and even essential product of the human body. Cerumen – the technical name for earwax – is produced in the external ear canal as a mixture of secretions from sebaceous and apocrine glands, dead skin cells, and dust. Its role is fascinating: it protects the delicate skin of the ear canal from drying out, traps dirt and microorganisms, and acts as a natural antibacterial barrier. Without earwax, the ear canal would be far more vulnerable to infections and irritation.
Under normal circumstances, earwax cleans itself. The movements of the jaw during chewing and speaking help the wax slowly travel from the eardrum toward the opening of the ear canal, from where it is naturally removed. Problems arise when this self-cleaning mechanism fails for some reason, or when too much wax is produced. And that is precisely when the unpleasant blockage occurs.

Why a blocked ear canal is not just a matter of hygiene
Many people think that a blocked ear is simply the result of insufficient hygiene. The reality, however, is more complex. Paradoxically, it is those who care for their ears too zealously who cause themselves the most trouble. Using cotton swabs – popular, but from a medical perspective highly problematic – pushes wax deeper into the ear canal instead of removing it, where it gradually compresses and forms a plug. This plug can then completely block the passage of sound to the eardrum, manifesting as that characteristic feeling of blockage, pressure, and reduced hearing.
The World Health Organization has repeatedly stated in its recommendations that cotton swabs are not a suitable tool for cleaning ears and their use can lead to injury of the ear canal or eardrum. Nevertheless, they remain one of the best-selling hygiene products in the world.
Increased earwax production can also be a hereditary matter – some people simply produce more wax than others. The shape of the ear canal also plays a role: a narrow or curved canal makes it harder for wax to drain naturally. People who wear hearing aids or earplugs are also more prone to earwax plug formation, as these devices prevent the natural movement of wax out of the ear.
An interesting example from practice: Jana, a forty-four-year-old teacher from Brno, complained for many months about a feeling of fullness in her left ear and occasional ringing. She thought it was a symptom of stress or an early problem with her jaw joint. It was only during a visit to an ear specialist that it turned out the cause was accumulated earwax that had completely blocked the ear canal. After a simple cleaning – ear irrigation – the problems disappeared immediately.
The feeling of a blocked ear is certainly not caused only by earwax. There can be a whole range of causes – from a common cold and middle ear infection, through allergies and a malfunctioning Eustachian tube, to rarer causes such as acoustic neuroma or Ménière's disease. It is therefore important not to underestimate persistent problems and to seek specialist advice if the feeling of blockage lasts more than a few days or is accompanied by pain, dizziness, or discharge from the ear.
What earwax does and why it is irreplaceable for ear health
Let us return to earwax itself – because its role in ear health is truly remarkable and deserves more attention than we usually give it. Earwax performs several key functions simultaneously, and its absence would cause serious problems for the ear canal.
Earwax (technically cerumen) acts as the first line of defence – trapping dust, dirt, but also insects and microorganisms that would otherwise penetrate deeper into the ear. It contains lysozyme – an enzyme with antibacterial properties – and fatty acids that maintain a mildly acidic environment in the ear canal. This acidic environment is a natural barrier to the growth of bacteria and fungi. It is therefore no coincidence that people who clean their ears too aggressively and remove all the wax are more prone to recurring inflammation of the ear canal – so-called otitis externa, commonly known as "swimmer's ear".
Wax also moisturises the skin of the ear canal and protects it from drying out and cracking. Dry, irritated skin in the ear canal is not only unpleasant but also more vulnerable to infection. In this sense, earwax is something like a natural moisturiser that the body applies exactly where it is needed.
As British ear specialist Mr. Roger Kelsey aptly noted: "Ears are like self-cleaning ovens. Most people should let them do their job and interfere as little as possible."
The composition of earwax differs according to ethnic origin. There are two basic types – wet and dry cerumen. The wet type, typical of people of European and African origin, is brownish to orange in colour and has a sticky consistency. The dry type, predominant among people of Asian origin, is lighter, flaky, and less sticky. This genetic variability is determined by a single gene and was scientifically described in research published in the journal Nature Genetics, which showed that the type of cerumen is closely linked to body odour production – a fascinating connection between two bodily functions that at first glance seem unrelated.
When it comes to proper ear care, expert recommendations are surprisingly modest. The outer part of the ear – the auricle and the very edge of the ear canal – can be gently wiped with a damp towel. The rest should be left to the body naturally. In cases where earwax accumulates in greater quantities and causes problems, there are safe care options: special ear drops based on olive oil or glycerol, which soften the wax and facilitate its natural drainage. These preparations are available without a prescription and, when used regularly, can prevent the formation of earwax plugs.
For those looking for natural and gentle alternatives, drops with olive oil are popular – a simple, natural, yet effective way to keep the ear canal in good condition. Olive oil softens the wax without disrupting the natural environment of the ear and has been used for this purpose for centuries. Preparations based on almond oil or glycerol work in a similar way. On the other hand, the popular "ear candling" – burning special candles inserted into the ear – has no scientifically proven efficacy and can be dangerous.
But when is it time to visit a doctor? If the feeling of a blocked ear lasts more than three to four days, or if it is accompanied by pain, fever, dizziness, or discharge from the ear, a visit to an ear specialist or at least a general practitioner is essential. People whose problems recur should also be alert, as should those who wear hearing aids and feel that their performance is deteriorating – the cause may be accumulated wax blocking the device's microphone.
Professional ear cleaning is performed by a doctor either by irrigation with warm water or by suction – both procedures are safe and quick. You should never attempt to remove an earwax plug yourself using sharp objects or cotton swabs, as the risk of injuring the eardrum or introducing an infection is real.
Ear health is closely linked to overall quality of life. Hearing loss – even temporary and caused solely by an earwax plug – affects communication, concentration, and psychological well-being. Research consistently shows that untreated hearing loss is associated with a higher risk of social isolation and cognitive decline in old age. Even a seemingly minor problem like a blocked ear is therefore worth addressing promptly and in the right way.
Ear care thus nicely illustrates a broader principle of a healthy lifestyle: less is sometimes more. The body has its own mechanisms that work reliably – if you give them space and do not interfere with inappropriate interventions. Gentle preparations, natural oils, and the occasional consultation with a specialist are all that healthy ears need in most cases. And next time that unpleasant feeling of pressure and muffled hearing strikes, perhaps all it will take is a drop of olive oil and a little patience.
