They may seem like a simple way to keep the ears clean, but cotton swabs can do more harm than good. Specialists say the ear has its own cleaning mechanism and that inserting objects into the ear canal can cause wax impaction, infections and even earrum injuries.
For many people, cleaning the ears with a cotton swab is part of their daily hygiene routine. After a shower, a few swipes inside the ear may seem harmless, especially when visible earwax is removed. Yet this common practice is strongly discouraged by health professionals.
The World Health Organization WHO says the inner part of the ear is naturally self-cleaning and that there is generally no need to remove earwax unless it is causing problems such as hearing loss.
Earwax is not dirt
The substance often considered a sign of poor hygiene actually has an important protective role. Known medically as cerumen, earwax helps trap dust, dirt and foreign particles while protecting and lubricating the ear canal. Normal movements such as chewing and the natural growth of skin gradually move old wax towards the opening of the ear, where it can fall away or be washed off.
This means that trying to remove every trace of wax is unnecessary. In most cases, the ear does the job itself.
Cotton swabs can push wax deeper
Rather than removing all the wax, a cotton swab can push part of it deeper into the ear canal. Repeated use may therefore contribute to a blocking, particularly when wax accumulates and becomes compacted. The American Academy of Otolaryngology–Head and Neck Surgery warns that inserting cotton-tipped swabs or other objects can worsen impaction and injure the delicate skin of the ear canal.
The risks do not stop at earwax. A cotton swab can scratch the ear canal, cause irritation or infection, and, if inserted too deeply, injure or perforate the eardrum. In some cases, the cotton tip itself can also become detached and remain inside the ear.
So how should the ears be cleaned?
The recommended approach is much simpler than many people think. The outer part of the ear can be gently cleaned with a soft, clean cloth or a little cotton. There is no need to insert anything into the ear canal. The WHO specifically advises against putting cotton buds, sticks, oil or other objects inside the ear unless a health professional has prescribed a treatment.
If excess earwax becomes hard and blocks the ear, it is better to seek advice from a
healthcare professional rather than trying to remove it with a cotton swab. Depending on the situation, a trained professional may use an appropriate method such as irrigation, microsuction or manual removal.
Ear drops or wax-softening products may sometimes be recommended, but they are not suitable for everyone. They should not be used without professional advice when there is a suspected ear perforation, ear infection or other ear problem.
When should you see a health professional?
Ear pain, discharge or bleeding, persistent itching, a feeling of blockage, ringing in the ear or difficulty hearing should not simply be treated by inserting a cotton swab. These symptoms can have causes other than excess wax and may require medical assessment.
The message from specialists is therefore straightforward: clean the outside, leave the inside alone, and seek professional help when there is a genuine problem. In ear care, doing less can often mean protecting more.
