Why Do Your Ears Feel Clogged After Driving Into the Mountains?

We all know the feeling of clogged or plugged ears when driving through the mountains. When elevation changes, hearing may sound muffled, or the ears may feel much more difficult to pop.
This occurs because the surrounding air in the external environment changes pressure faster than the air pressure changes in the middle ear. Normally, this resolves some time after driving into the mountains. However, symptoms may persist or recur, which may potentially point to a problem with the eustachian tubes.
Here at ENT & Sinus Center, we help patients in Rancho Cucamonga, CA, understand what may be causing persistent ear problems after driving through the mountains.
Why Do My Ears Feel Clogged After Driving Into the Mountains?
As we ascend or descend through mountains, the surrounding external air pressure changes. The Eustachian tubes open periodically to equalize air pressure in the middle ear with the surrounding air pressure.
However, sometimes, these tubes do not open quickly enough to equalize ear pressure, which may cause pressure to build up behind the eardrums. This may cause symptoms such as:
- Muffled hearing
- A feeling of fullness or pressure in the ear
- Popping or clicking sounds in the ear
- Mild ear pain
- A sensation that the ear needs to “pop”
Yawning, chewing, or swallowing can help the eustachian tubes to open and close. However, persistent or severe ear issues may warrant additional ear evaluation.
What Are the Eustachian Tubes?
The eustachian tubes are made of bone and cartilage, and run from the middle ear to the back of the nose and throat. These tubes remain closed and briefly open when you yawn, chew, or swallow.
The eustachian tubes are responsible for equalizing air pressure behind the eardrums, draining fluid from the middle ear, and protecting the middle ear from substances in the nose and throat.
There is one eustachian tube in each ear. During elevation changes, such as driving through mountains, the tubes need to open more frequently to equalize air pressure in the ear.
What Happens When You Drive Into the Mountains?
As elevation changes, so does air pressure. This is what happens when we drive into the mountains. When we drive uphill, the pressure inside the middle ear may be greater than the external air pressure. To restore balanced air pressure, the eustachian tubes release air from the middle ear. During this time, most people may hear or feel a small “pop” in the ear when this happens.
However, if the eustachian tubes do not open as efficiently, some people may experience ear pain, discomfort, or muffled hearing.
The same mechanism also happens during airplane takeoff and descent.
How Long Should Clogged Ears Last?
Mild ear pain or discomfort typically resolves during the drive or shortly after returning to a stable elevation. You can try swallowing, yawning, or chewing gum during the drive.
However, several factors can prolong the clogged or plugged sensation in the ears. This may include:
- The common cold
- Allergies
- Sinusitis or a sinus infection
- Fluid buildup in the middle ear
- Eustachian tubes that don’t open effectively
- Rapid changes in elevation
If you are experiencing persistent symptoms that last for more than a few days, or symptoms that worsen or recur frequently, consider additional evaluation from an ENT care provider.
When Could It Be Eustachian Tube Dysfunction?
Eustachian tube dysfunction (ETD) occurs when one or both Eustachian tubes do not open or close as they normally should, which can interfere with pressure regulation in the middle ear.
One form of ETD, called baro-challenge-induced ETD, causes difficulty equalizing middle-ear pressure during altitude changes, such as mountain drives or airplane flights.
Common symptoms may include:
- Ear fullness or pressure during elevation changes
- Muffled hearing, which can sound like you’re underwater
- Difficulty “popping” the ear
- Ear pain or discomfort
- Clicking, popping, or crackling sound in the ear
- Tinnitus
- Ear issues that may persist after the drive ends
The symptoms listed above may be associated with ETD. However, the presence of symptoms alone does not confirm a diagnosis.
What Else Can Make Pressure Equalization More Difficult?
ETD isn’t the only factor that can make it difficult for the eustachian tubes to equalize air pressure. Several factors may contribute as well, such as:
- Allergies: Allergies may cause swelling and inflammation around the openings of the eustachian tubes, which can impair function.
- Colds and flu: Upper respiratory infections, such as the common cold or flu, may cause swelling and inflammation in the nose and upper throat. Ear pressure can be one of many symptoms, mostly due to the inflammation.
- Sinus inflammation: Chronic sinus inflammation and sinusitis may impact the surrounding tissues of the Eustachian tubes.
- Fluid buildup or infection in the middle ear: Fluid buildup behind the eardrum may interfere with air pressure regulation. Moreover, an active middle ear infection may cause significant ear issues.
- Age and ear anatomy: Children may be more prone to air pressure issues due to the anatomy of their eustachian tubes. However, this is not to say that adults can’t develop ETD as well.
Simple Remedies to Help Your Ears Equalize Air Pressure During a Drive
Air pressure problems in the ear during elevation changes may be resolved with simple remedies such as:
- Swallowing
- Yawning
- Chewing gum
- Sipping water
- Staying awake during steep climbs or descents
- Using saline nasal sprays for dry or congested nasal passages
Remember, any attempt to equalize air pressure should be gentle and never forceful. Any forceful attempt to pop the ear may increase pain or cause injury.
When Is It Time to Seek Medical Attention?
Consider scheduling an ENT evaluation if you are experiencing:
- Ear issues during nearly every elevation or altitude change
- Significant or worsening ear pain
- Ear pressure that persists for more than a few days
- Persistent muffled hearing well after the drive
- One ear that refuses to clear or pop
- Symptoms that occur with chronic nasal congestion or allergies
- Ringing in the ears, dizziness, or recurring ear infections
Moreover, seek prompt medical attention for:
- Sudden or substantial hearing loss
- Intense pain or swelling behind the ear
- Severe vertigo
- Blood, pus, or fluid draining from the ear
- Facial weakness
- Worsening ear symptoms accompanied by high fever
Find Out Why Your Ears Feel Clogged
A clogged sensation in the ear when driving through mountains can occur due to the difference between the pressure in the middle ear and the surrounding environment. When eustachian tube function is impaired, ear symptoms and issues may persist, worsen, or recur during elevation and altitude changes.
Schedule a consultation with ENT & Sinus Center to determine if ETD or some other ear condition may be contributing to persistent ear issues.
We offer ear, nose, and throat care services for patients in Rancho Cucamonga and nearby communities.
