Ear popping happens when the pressure inside your middle ear doesn’t match the pressure outside. You can’t completely eliminate it, but you can control how and when it happens so it stays comfortable rather than painful. The key is keeping a small tube behind your eardrum, called the Eustachian tube, opening and closing smoothly as pressure changes around you.
Why Your Ears Pop in the First Place
Your middle ear is a small, sealed space behind the eardrum. The lining of this space constantly absorbs oxygen and carbon dioxide through tiny blood vessels, which slowly creates a slight vacuum compared to the air pressure around you. Normally, a narrow passage called the Eustachian tube opens briefly when you swallow or yawn, letting a small puff of air in to rebalance the pressure. That rebalancing is the “pop” you hear.
When pressure outside your ear changes quickly, like during airplane descent, driving through mountains, or diving underwater, that vacuum builds faster than your Eustachian tube can correct. The eardrum gets pushed inward by the higher outside pressure, causing fullness, muffled hearing, and pain. If the pressure difference exceeds about 90 mmHg, the tube can lock shut entirely, making it much harder to equalize.
Why Descent Is Worse Than Going Up
Most people notice more discomfort when descending, whether that’s a plane landing or a diver going deeper. During ascent, the expanding air in your middle ear can push its way out through the Eustachian tube relatively easily. During descent, though, the tube has to actively open against increasing outside pressure to let air in. This is why the last 20 minutes of a flight tend to be the problem, not takeoff.
Techniques That Help Equalize Pressure
Several methods can coax the Eustachian tube open before the pressure difference gets too large. In clinical testing, the two most common techniques, the Valsalva and Toynbee maneuvers, performed equally well in healthy adults, each succeeding about 52% of the time per attempt. The trick is using them early and often rather than waiting until your ears already hurt.
Swallowing and Yawning
The simplest approach. Two small muscles attached to the Eustachian tube contract every time you swallow or yawn, pulling the tube open momentarily. Chewing gum, sipping water, or sucking on hard candy during altitude changes keeps those muscles firing regularly. This is passive and gentle, which makes it the best first option.
The Valsalva Maneuver
Pinch your nostrils shut, close your mouth, and blow gently as if trying to exhale through your nose. This pushes air from your throat up into the Eustachian tubes. The key word is gently. Blowing too hard can damage your inner ear. Use short, mild puffs rather than one sustained push.
The Toynbee Maneuver
Pinch your nostrils shut and swallow. The swallowing motion opens the Eustachian tubes while your pinched nose creates a slight pressure change to help air move. Many people find this more comfortable than the Valsalva because it uses the natural muscle action your body already knows.
The Frenzel Maneuver
Pinch your nostrils, close the back of your throat as if you’re about to lift something heavy, then make the sound of the letter “K.” This pushes the back of your tongue upward, compressing air against the openings of the Eustachian tubes. Scuba divers prefer this method because it uses throat muscles rather than lung pressure, making it safer at depth. It takes some practice but works well once you get the feel for it.
Timing Matters More Than Technique
Whichever method you choose, start early. On a plane, begin swallowing or gently equalizing as soon as the captain announces the descent, not when your ears start aching. Equalize every few seconds during the first minutes of descent. Once a large pressure gap builds up and locks the tube, none of these techniques will work easily, and forcing air harder just increases the risk of injury.
If you’re scuba diving, equalize before you feel pressure and do it continuously as you descend. Divers who wait until they feel discomfort are already past the point where gentle equalization is effective. If you can’t clear your ears, stop descending or ascend slightly until you can.
What About Pressure-Regulating Earplugs?
Special earplugs marketed as “pressure-equalizing” plugs are widely sold for air travel. However, a controlled study found they did not prevent barotrauma during descent from cruising altitude. About 75% of volunteers wearing them still experienced ear pain, and ears using the active earplugs actually scored worse on examination than ears with placebo plugs. Most users did report a pleasant noise-reducing effect, so they may help with cabin noise, but they shouldn’t be relied on to prevent pressure problems.
Decongestants and Nasal Sprays
If you’re congested from a cold, allergies, or a sinus infection, your Eustachian tubes are already swollen and less able to open. An oral decongestant taken 30 to 60 minutes before descent can shrink that swelling and give the tubes more room to function. A topical nasal decongestant spray used about 30 minutes before landing works similarly but acts more locally.
That said, a clinical consensus from ear, nose, and throat specialists found no strong evidence that decongestants, antihistamines, or steroid nasal sprays effectively treat ongoing Eustachian tube dysfunction when no other underlying cause is present. They’re most useful as a short-term strategy for flying with a cold, not as a long-term fix for chronic pressure problems.
Conditions That Make Popping Harder
Some people are more vulnerable to pressure-related ear discomfort. Common risk factors include having a cold or sinus infection, allergic rhinitis (seasonal or year-round allergies), an active ear infection, and simply having smaller Eustachian tubes, which is why infants and toddlers struggle more than adults. Falling asleep during descent on a plane is another underappreciated risk, because you stop swallowing and the pressure gap builds unchecked while you sleep.
If you’re flying with a baby or toddler, have them drink from a bottle or sippy cup during takeoff and landing. The sucking and swallowing motion keeps their Eustachian tubes opening regularly. For older children, gum or a lollipop works well.
Signs That Something Went Wrong
Normal ear popping resolves within minutes to a few hours after the pressure change ends. Lingering fullness for a day after a flight is common and usually clears on its own. But certain symptoms suggest actual tissue damage: drainage or bleeding from the ear, fever, severe ear pain that doesn’t fade, or moderate to severe hearing loss. These can indicate a ruptured eardrum or fluid buildup in the middle ear that needs medical evaluation.
People who experience painful ear pressure on nearly every flight, or who can never seem to equalize despite using the techniques above, may have chronic Eustachian tube dysfunction. This is a recognized condition with treatment options ranging from nasal steroid sprays to a relatively newer procedure where a small balloon is used to widen the Eustachian tube, which was approved by the FDA in 2016 and has shown better outcomes than medication alone in clinical trials.
