Imagine digging up an ancient site and finding a bunch of cool old tools. That’s exactly what happened when archaeologists explored a 5,000-year-old Sumerian burial site. Among the artifacts, they found tools like tweezers and ear scoops, which were used for grooming. Even today, people still use tools to remove earwax as part of their hygiene routine.
Earwax, or cerumen, isn’t just something humans have. Other mammals, like whales, produce it too. In fact, a blue whale was once found with a massive earwax plug that was 25 centimeters long! Earwax forms in our outer ear canals when dead skin cells mix with oily sweat from special glands called apocrine glands. This sweat is different from the kind that cools us down because it’s oilier. When you mix this oily sweat with sebum (the oil on our faces and scalps), you get earwax.
Earwax might seem gross, but it actually helps keep our ears healthy. It acts like a natural moisturizer, preventing dryness and itchiness. It also traps dirt and germs, forming a protective barrier for the skin in our ear canals. Plus, it has proteins that fight off bacteria. Our ears have a cool way of getting rid of old earwax: as new skin cells grow, they push the old ones out, moving the wax toward the ear’s opening. This happens every day, with skin moving about 100 micrometers outward.
Using things like cotton swabs to clean your ears might seem like a good idea, but it can actually push wax further in and scratch the ear canal. This can mess up the ear’s natural defenses and even lead to infections. Some people try ear candling, which involves using a lit candle to supposedly suck out earwax. However, studies show that this doesn’t work well and can even cause injuries.
As people get older, they might experience more earwax buildup, which can be uncomfortable and affect hearing. If this happens, there are safer ways to handle it. Over-the-counter eardrops can soften the wax, helping it to come out naturally. Doctors can also use gentle methods to clear blockages. To prevent buildup, it’s a good idea to clean the outer ear with a damp cloth and take breaks from using earplugs and earbuds. If your ears aren’t blocked, it’s usually best to leave the earwax alone.
Try creating a model of how earwax forms using household items. Mix oil, water, and flour to simulate the formation of earwax in the ear canal. Observe how the mixture behaves and discuss how this relates to the natural process in the human body.
Conduct a simple experiment to understand how earwax protects the ear. Use a small amount of petroleum jelly on a piece of paper to represent earwax. Sprinkle dirt over it and observe how the jelly traps the dirt, similar to how earwax traps particles in the ear.
Research the different methods people use to remove earwax and their effectiveness. Create a short presentation to share your findings with the class, highlighting the safest and most effective methods.
Pair up with a classmate and role-play a doctor’s visit where one of you is experiencing earwax buildup. Discuss symptoms, possible treatments, and preventive measures. This will help you understand the importance of proper ear care.
Create a poster that educates others about the role of earwax and the importance of ear health. Include tips on how to safely manage earwax and why it’s usually best to leave it alone unless there’s a problem.

Investigating a nearly 5,000-year-old Sumerian burial site, archaeologists discovered intriguing sets of artifacts. They identified them as toiletry kits, which included pointed tools, tweezers, and ear scoops. Grooming items, such as earwax removal tools, have been found at various archaeological sites, and earwax removal remains a common hygienic practice today.
So, what is earwax, and is it beneficial to remove it? To begin with, humans are not the only ones who produce earwax. Other mammals do as well; for instance, a 12-year-old blue whale was found with an earwax plug measuring 25 centimeters long. Earwax, scientifically known as cerumen, forms in our outer ear canals when skin cells shed and mix with other substances, including sweat. However, the sweat in our ears is different from the sweat produced by eccrine glands throughout our bodies; it comes from apocrine glands and is oilier. The combination of dead skin, oily sweat, and sebum—the fatty oil found on our faces and scalps—results in earwax.
Earwax can vary in odor, color, and consistency. Some types are flaky and dry, while others are sticky and gooey. A single nucleotide change in one gene determines the type of earwax a person has by influencing the amount of fat secreted by the ear’s apocrine sweat glands. This type may also correlate with ancestry; for example, drier earwax is more common among individuals of East Asian descent, while wetter earwax is often found in people of African and European descent.
But why do we have earwax? These secretions play a role in maintaining ear health. Earwax acts as a lubricant, preventing dryness and itchiness, trapping debris and microbes, and forming a protective barrier for the ear canal’s skin. It also contains proteins that help combat bacterial infections. The ear has a natural mechanism for expelling earwax: as new skin cells form at the center of the eardrum, they push older cells toward the ear canal’s opening, effectively moving the wax out. This process occurs daily, with skin migrating outward about 100 micrometers.
Using objects to remove earwax can be counterproductive. Even if swabbing removes some wax, it may push more back in and can cause scratches in the ear canal, disrupting its natural defense against infections. Deep cleaning poses risks, including potential damage to the eardrum, which can lead to hearing loss.
Some services claim to clear earwax but should be approached with caution. For example, ear candling involves placing a lit hollow candle over the ear canal, purportedly to create suction to remove earwax. However, research indicates that the suction is minimal, and the visible residue is likely debris from the candle, not earwax. This practice can result in injuries and leave debris in the ear.
Certain individuals may be more susceptible to earwax buildup, especially as they age. While earwax accumulation can be uncomfortable and affect hearing, there are safer methods for addressing it. Over-the-counter eardrops can help soften earwax, allowing it to exit naturally. Healthcare providers also have effective techniques for gently clearing blockages. To prevent earwax buildup, doctors recommend cleaning the outer ear canal with a damp cloth and taking breaks from earplugs and earbuds when possible. In general, if there are no obstructions, it’s best to leave earwax alone.
