The sticky stuff we call ear wax isn't related to the paraffin wax that candles are made of. Ear wax is secreted by cerumen glands in the skin of your ear canals.

This substance is part of your ear's natural cleaning mechanism. Dirt, bacteria, and even insects that might fly into your ears are trapped by the wax so the foreign materials don't harm your eardrum. The dirty wax slowly slides out of your ear canal and takes the gunk away. Sometimes ear wax builds up and causes hearing problems that require a doctor to remove the blockage.

People produce different types of ear wax. Studies have found two kinds -- dry wax, which has about 20% lipid (fat), and wet wax, which has 50% lipid. The latter variety can be harder and lead to buildup.

Some people simply create more ear wax than others. Their ear canals may be narrower and more easily blocked or at an angle that makes it hard for wax to fall out. Hairy ear canals can obstruct the process, too. As people age, more ear wax may build up. Even working in dusty environments can cause dirt to get stuck in the ear and lead to blockages.

What is Ear Wax?

1. Ear wax is a substance produced by glands inside of the ears. Normal ear wax is usually yellowish to brownish in color. Ear wax only forms in the outer third of the ear canal and slowly works its way out through the ear's opening. This occurs naturally when people talk, chew, and otherwise move their jaws. Eventually the old ear wax dries up, turns to flakes and falls out harmlessly.

The Purpose of Ear Wax

2. Ear wax is produced because it has a specific purpose. It is an important part of the ear's natural cleaning process. Ear wax assists with this cleaning because it has natural lubricating properties, and it is also an anti-bacterial substance. Because it is sticky when first produced, it helps to trap dirt and dust before they can get to the ear drum.

Misconceptions About Ear Wax

3. Many people believe that ear wax should be regularly cleaned out of the ears so it doesn't build up. This is a misconception; an unhealthy build-up of ear wax is actually uncommon. Cleaning when it's not necessary can be more harmful than helpful and can actually cause a build-up because inserting a foreign object like a cotton swab into the ear can push the wax down towards the ear drum. Wax should never be pushed farther into the ear because this can cause a blockage.

Natural Ear Wax Build-Up

4. Although it is not common for ear wax to build up on its own, this can happen to people who are born with an ear canal that has a bend. This condition is know as "twisted ear canal," and it can interfere with the natural path of the wax as it works its way out of the ear.

Recognizing Ear Wax Build-Up

5. If you have a build-up of ear wax, you may notice that your ears feel dry and itchy. They may also be painful and you might experience some hearing loss. If you're experiencing these symptoms, check with your doctor before trying anything on your own.
