Ear infections are one of the most common health concerns for both children and adults. They can be painful, disruptive, and—if they happen frequently—can even impact long-term hearing health. By understanding why ear infections happen and what steps help prevent them, you can better protect your ears and know when it’s time to reach out to an audiologist for expert care.
In this guide, we’ll break down how ear infections develop, what symptoms to look for, and simple ways to reduce the risk for your family.
What Ear Infections Are and How They Develop
An ear infection occurs when the middle ear becomes inflamed or filled with fluid. This often happens after a cold, sinus infection, or allergy flare-up that causes swelling and blockage in the Eustachian tube—the small passage that drains fluid from the middle ear into the throat.
When this tube becomes narrow or clogged, fluid builds up behind the eardrum, creating a breeding ground for bacteria or viruses.
There are a few main types of ear infections:
- Acute ear infections, which come on quickly and cause pain.
- Chronic ear infections, which linger or keep returning.
- Recurrent infections, when someone experiences multiple infections in a short period.
Why Ear Infections Are So Common
Ear infections can affect anyone, but certain factors make them especially common for young children and people prone to congestion or allergies.
1. Age and Anatomy
Children have shorter, more horizontal Eustachian tubes. This makes drainage more difficult and blockages more likely, which is why ear infections are most common between ages 6 months and 3 years.
2. Colds, Flu, and Allergies
Anything that causes swelling in the nose or throat—such as seasonal allergies, sinus infections, or viral illnesses—can lead to fluid buildup in the middle ear.
3. Environmental Triggers
Some surroundings or habits can increase ear infection:
- Secondhand smoke
- Daycare settings where colds spread easily
- Bottle feeding while a child is lying flat
- Frequent swimming (which can irritate the ear canal)
4. Underlying Hearing or Sinus Issues
Sometimes recurring infections signal something deeper—such as structural issues, consistent fluid retention, or early hearing problems. In these cases, an audiologist can help identify and monitor changes in hearing or middle-ear function.
Signs and Symptoms to Watch For
Although symptoms vary, common signs of an ear infection include:
- Ear pain or pressure
- Tugging or rubbing at the ear (common in children)
- Fluid draining from the ear
- Difficulty hearing or muffled sound
- Irritability or trouble sleeping
- Fever (especially in children)
- Balance problems or dizziness
If symptoms last more than a couple of days, worsen, or keep returning, it may be time to speak with an audiologist or healthcare provider.
What Helps Prevent Ear Infections
The good news is that many ear infections can be reduced or prevented with simple habits and early intervention.
1. Support a Healthy Immune System
Regular handwashing, good sleep habits, and proper hydration help reduce colds and infections that can trigger ear issues.
2. Reduce Congestion and Allergy Symptoms
Managing allergies, using saline rinses, and treating sinus symptoms early can help keep the Eustachian tubes functioning properly.
3. Practice Good Feeding and Air Quality Habits
- Keep infants upright during feeding.
- Avoid exposure to cigarette smoke, which is strongly linked to chronic ear infections.
4. Protect the Ears During Swimming
For frequent swimmers, drying the ears thoroughly after water activities—or using audiologist-recommended earplugs—can help prevent irritation and infection.
5. Schedule Preventive Hearing Care
Routine checks with an audiologist can detect lingering fluid, early hearing changes, or structural issues that may increase the risk of infection. Early diagnosis leads to more effective treatment and fewer long-term complications.
When to See an Audiologist or Healthcare Provider
You should contact an audiologist if you or your child experiences:
- Repeated ear infections
- Hearing difficulties or muffled sound
- Balance concerns
- Ear infections lasting longer than expected
- Speech delays in children that may be tied to hearing issues
An audiologist can perform a thorough hearing evaluation, assess middle-ear function, and guide you toward the right treatment or referral if needed.

Frequently Asked Questions
Why do ear infections happen so often?
The Eustachian tube can easily become blocked by swelling from colds, allergies, or environmental factors.
Can adults get ear infections?
Yes. Adults can develop ear infections due to sinus issues, allergies, smoking exposure, or chronic congestion.
Do ear infections affect hearing?
Temporary hearing changes are common. Frequent infections may lead to longer-term concerns, which is why monitoring with an audiologist is important.
When should I worry about recurring ear infections?
If infections happen multiple times a year or impact hearing, consult an audiologist for a full evaluation.
