Equalizing your ears means forcing the narrow tube that connects your middle ear to your throat to open briefly, letting air flow in or out to match the pressure around you. The simplest version is something most people already do instinctively: swallowing, yawning, or pinching your nose and gently blowing. But those reflexive techniques don’t always work, especially when pressure changes happen fast, and the consequences of failing to equalize range from sharp pain to actual injury. Which method works best depends on what you’re doing, how fast the pressure is changing, and whether your Eustachian tubes are cooperating.
Why Pressure Builds Up in the First Place
Your middle ear is a small, air-filled space sealed off from the outside world by the eardrum. When the pressure outside your body changes and the air inside that space doesn’t adjust to match, the eardrum gets pushed inward or outward, which you feel as fullness, discomfort, or pain. This happens because the volume of a gas changes when the pressure around it changes: compress the air and it shrinks; reduce the pressure and it expands. That’s the basic physics behind every ear-pressure problem, whether you’re on a descending airplane, diving underwater, or riding a fast elevator.1PubMed. Aerospace Pressure Effects
The only natural escape valve for that trapped air is the Eustachian tube, a passage roughly the width of a pencil lead that runs from each middle ear down to the back of your throat. It’s normally closed. It opens briefly when you swallow, yawn, or perform certain maneuvers, letting a tiny puff of air equalize the pressure on both sides of the eardrum. When this works well, you don’t even notice. When it doesn’t, the pressure difference builds and the eardrum gets stretched, which is when the pain starts.
The Three Main Equalization Techniques
There are three widely used maneuvers, and they work through different mechanisms. All three aim to open the Eustachian tube, but they do it in distinct ways, and each has situations where it shines or falls short.
The Valsalva Maneuver
Pinch your nostrils shut, close your mouth, and gently blow as if trying to push air out of your nose. The increased pressure in your throat forces air up through the Eustachian tube into the middle ear. You’ll often feel a soft pop or click when it works. This is the technique most people learn first, and it’s the one doctors and flight attendants most commonly recommend. In a study comparing equalization techniques in healthy volunteers, the Valsalva maneuver succeeded in equalizing middle ear pressure in just over half the ears tested.2Elsevier / Auris Nasus Larynx. A comparative study on efficiency of middle ear pressure equalization techniques in healthy volunteers
The biggest drawback is that Valsalva only works well for pushing air into the middle ear, which is what you need during descent. If you need to let air out, as when ascending from a dive, it’s less useful. It also requires you to blow hard enough to overcome the tube’s resistance but gently enough not to create other problems, like dizziness or, in extreme cases, damage to the round window of the inner ear. The general advice is to blow gently and stop as soon as you feel the pop. If nothing happens after a moderate effort, don’t force it.
The Toynbee Maneuver
Pinch your nose shut and swallow. Swallowing naturally opens the Eustachian tube while the pinched nose creates a brief negative pressure in the nasopharynx, which can pull air out of the middle ear or allow it to rebalance. The Toynbee maneuver tends to produce a sensation of fullness as the pressure in one or both middle ears shifts.3PubMed. Study of Toynbee phenomenon by combined intranasopharyngeal and tympanometric measurements It’s especially helpful during ascent, where you need to let excess air escape rather than push more in. Many divers and frequent flyers alternate between Valsalva on the way down and Toynbee on the way up.
Swallowing with a sip of water can make the Toynbee maneuver more effective than dry swallowing, because the physical act of moving liquid triggers a stronger swallow reflex and a more complete opening of the Eustachian tube.4PubMed Central. Comparative Evaluation of Wet and Dry Swallowing in Assessing Eustachian Tube Function in Tympanic Membrane Perforation This is one reason flight attendants hand out drinks or hard candies before landing: chewing and sipping encourage repeated swallowing.
The Frenzel Maneuver
This one takes some practice but is the technique of choice for scuba divers, freedivers, and anyone dealing with rapid, large pressure changes. You close your nose, close the back of your throat (as if you’re about to say the letter “k”), and then push your tongue upward and backward. The tongue acts like a piston, compressing air in the nasopharynx and forcing it into the Eustachian tubes without needing a big breath or sustained effort.
Compared to the Valsalva maneuver, the Frenzel generates a lower peak pressure in the Eustachian tube but opens it more quickly.5SpringerLink (Eur Arch Otorhinolaryngol). Prospective study on the Eustachian tube function during Frenzel maneuver in a hypobaric/hyperbaric pressure chamber That matters underwater, where a sudden forceful Valsalva can cause problems, and where you may need to equalize every meter or two on the way down. The Frenzel also doesn’t require a lung full of air, so it’s usable at any point in a breath cycle. The downside is that most people need coaching and practice before they can do it reliably.
Flying and Ear Pressure
Airplane cabins are pressurized, but not to sea-level pressure. A typical cruising altitude corresponds to a cabin altitude equivalent to about 6,000 to 8,000 feet. The problem usually hits hardest during descent, when the cabin pressure rises quickly and the air in your middle ear is at a lower pressure than the air pushing against the outside of your eardrum. This is when people clutch their ears and wince. If you’ve ever had a bad cold and flown, you know the feeling can escalate to genuinely sharp pain.
Staying ahead of the pressure change is the single most important tactic. Start swallowing, yawning, or performing a gentle Valsalva as soon as you feel the plane begin to descend, and repeat every 15 to 30 seconds. Waiting until the pain is already intense makes equalization harder, because the pressure difference can effectively lock the Eustachian tube shut. If you’ve been sleeping, set an alarm for the expected descent period. Once the tube is locked, it can take significantly more force to open it, which raises the risk of injury.
For adults who routinely have trouble equalizing on flights, taking an oral decongestant about 30 minutes before landing can help. One well-designed trial found that 120 mg of oral pseudoephedrine cut the rate of barotrauma symptoms roughly in half compared to a placebo group.6PubMed. A double-blind comparison between oral pseudoephedrine and topical oxymetazoline in the prevention of barotrauma during air travel That same trial found that oxymetazoline nasal spray, a topical decongestant, was barely better than placebo. A systematic review confirmed the level of evidence supporting oral pseudoephedrine for adults but noted it doesn’t appear to be effective in children.7Otology & Neurotology. Prevention of Otic Barotrauma in Aviation: A Systematic Review Meanwhile, the evidence on whether oral pseudoephedrine works for kids is essentially inconclusive, and it can cause drowsiness in children.8PubMed Central.

Do Pressure-Equalizing Earplugs Work?
You’ve probably seen filtered earplugs marketed specifically for flying, claiming to slow the rate of pressure change reaching your eardrum. The idea is appealing: pop them in and let the filter do the work. Unfortunately, a controlled study testing these plugs during descent from 8,000 feet cabin altitude found no difference in middle ear pressure between the active earplugs and placebo earplugs. About three-quarters of subjects still experienced ear pain, and the ears with the active earplugs actually scored worse on post-descent otoscopy than the placebo ears.9PubMed. Pressure-equalizing earplugs do not prevent barotrauma on descent from 8000 ft cabin altitude Most volunteers did enjoy the noise reduction, which might explain the positive reviews, but as a pressure-management tool, these earplugs are not supported by the evidence.
Diving and the Urgency of Early Equalization
Underwater, pressure changes are far more dramatic and rapid than in an airplane. Every 10 meters of seawater descent doubles the absolute pressure compared to the surface. The first few meters are the most dangerous because the relative change in pressure is greatest near the surface. Divers are exposed to large pressure gradients within just the first few meters of descent, creating a serious risk of middle ear barotrauma if equalization fails.10PubMed. SCUBA Medicine for otolaryngologists: Part I. Diving into SCUBA physiology and injury prevention
The rule drummed into every scuba student is to equalize early and often, ideally before you feel any discomfort. Once a pressure lock sets in, continuing to descend only makes it worse and can lead to tympanic membrane rupture, middle ear hemorrhage, or perilymph fistula. If you can’t equalize, the correct response is to ascend slightly until the pressure difference decreases enough for the tube to open. Experienced divers typically equalize every half-meter to one meter on descent, using the Frenzel maneuver for its speed and lower force.
On ascent, the situation reverses: expanding air needs to escape the middle ear. For most divers, this happens passively as the Eustachian tube vents automatically. Problems are rarer on the way up, but they can still occur, especially if swelling from a cold or allergy has narrowed the tube.
Why Children Have a Harder Time
If you’ve ever traveled with a screaming toddler on a plane, the problem isn’t just that they can’t follow instructions. Children’s Eustachian tubes are structurally different from those of adults. In young children, the tube is shorter, more horizontal, and has less cartilaginous support. One anatomical study found that Eustachian tube length increased from about 32 mm in children under four to 41 mm in those between 8 and 18 years old, and the angle of the tube also became steeper with age.11PubMed Central. Developmental Anatomy of the Eustachian Tube: Implications for Balloon Dilation A shorter, flatter tube doesn’t drain or ventilate as efficiently, which is also why children are far more prone to middle ear infections.
For infants and toddlers who can’t perform a Valsalva, the best strategy during flights is to encourage swallowing during descent: breastfeeding, bottle-feeding, or offering a pacifier. Older children can be taught to pinch and blow, but they often need reminders to start before the pain sets in.
When Equalization Just Doesn’t Work
Some people do everything right and still can’t equalize. The most common culprit is Eustachian tube dysfunction, a broad term covering three main types: functional obstruction, where the tube can’t open properly despite having a normal structure; muscular failure, where the muscles that pull the tube open don’t contract effectively; and anatomical obstruction, where something physically blocks the tube.12PubMed Central. Eustachian tube dysfunction: consensus statement on definition, types, clinical presentation and diagnosis
Upper respiratory infections, sinusitis, and nasal polyps are common temporary causes. When the mucous membranes around the tube swell, the tube simply can’t open wide enough to let air through. Allergies are a significant and often underappreciated factor. Research has shown a strong link between allergic disease and chronic middle ear problems in children, with investigators consistently finding that a high proportion of children with persistent middle ear fluid are atopic.13SAGE Journals (Ear, Nose & Throat Journal). The Relation of Allergy to Eustachian Tube Dysfunction and the Subsequent Need for Insertion of Pressure Equalization Tubes For adults with chronic equalization problems, allergy testing and treatment are worth pursuing even if allergies aren’t the first suspect.
There’s also a less well-known condition called patulous Eustachian tube, where the tube stays open too much rather than too little. People with this condition hear their own breathing and voice echoing in their ears, and they may feel constant pressure fluctuations. It’s essentially the opposite of the more common blocked-tube problem, and it requires a different treatment approach.14PubMed Central / Elsevier. Patulous Eustachian tube (PET), a practical overview
Medical and Surgical Options for Chronic Problems
If maneuvers, decongestants, and allergy treatment aren’t enough, there are procedural options. The most talked-about newer approach is balloon dilation of the Eustachian tube. A small balloon is threaded into the Eustachian tube through the nose and briefly inflated, widening the passage. In a randomized controlled trial, patients who received balloon dilation showed resolution of their eardrum retraction or fluid in about 70% of cases at six months, compared to zero improvement in the control group.15PubMed Central. Balloon Dilation of the Eustachian Tube: A Randomized Controlled Trial with 6 Months Follow-Up The procedure is relatively new, and long-term data is still accumulating, but initial results are encouraging for people with chronic dilatory dysfunction who haven’t responded to conservative treatment.
Pressure equalization tubes, the small tubes surgically placed through the eardrum, are the older and more established option. They bypass the Eustachian tube entirely by creating a direct vent through the eardrum itself. They’re most commonly placed in children with recurrent ear infections or persistent fluid, but they can also be used in adults who need reliable equalization for their work or lifestyle. The tube typically falls out on its own after several months to a year.
Hyperbaric Chambers and Repeated Pressure Exposure
Patients undergoing hyperbaric oxygen therapy face a unique challenge. They’re subjected to pressure changes repeatedly over a course of treatment, sometimes daily for weeks. A large review of over 5,900 patients found that middle ear barotrauma occurred in roughly 9% of treatments, with the majority being mild. Women over 50 and anyone with ongoing upper respiratory inflammation were at higher risk. Among patients who already had difficulty equalizing or reported ear pain during the initial pressurization phase, about one in five went on to develop barotrauma during that session.16Undersea and Hyperbaric Medicine. Middle ear barotrauma during hyperbaric oxygen therapy; a review of occurrences in 5,962 patients
For these patients, the same equalization maneuvers apply, but the staff controlling the chamber can help by slowing the rate of pressurization. If a patient signals trouble, the descent can be paused or reversed. This controlled environment is actually safer than open-water diving in that respect, because the pressure changes can be adjusted in real time.
The Connection Between Ear Pressure and Tinnitus, Fullness, and Pain
Chronic ear pressure problems don’t always present as straightforward pain during altitude changes. Some people experience a cluster of symptoms that includes persistent ear fullness, tinnitus (ringing or buzzing), sensitivity to sound, and ear pain, even without any obvious pressure change. Research investigating these patients found that most had either involuntary contractions of the small muscles in the middle ear or underlying Eustachian tube dysfunction that could be triggered by sound, physical movements like jaw clenching, or pressure changes in the ear canal.17PubMed Central / Elsevier. Exploring the middle ear function in patients with a cluster of symptoms including tinnitus, hyperacusis, ear fullness and/or pain
If you have ongoing tinnitus or ear fullness that gets worse with pressure changes, jaw movement, or loud noise, it’s worth mentioning to an ear, nose, and throat specialist rather than assuming it’s just a wax problem or that you need to pop your ears more. The underlying cause could be muscular rather than pressure-related, and the treatment approach would be different.
Practical Tips That Actually Help
Bringing together what the evidence supports, here are the strategies worth using:
- Start early: Begin equalizing before you feel discomfort, whether on a plane, in water, or in a pressure chamber. Once a pressure lock sets in, everything gets harder.
- Stay hydrated: Dry mucous membranes are stickier and less pliable, making the Eustachian tube harder to open. Drink water and avoid alcohol before flights or dives.
- Avoid flying or diving with a cold: Swollen nasal passages and Eustachian tube linings are the most common reason equalization fails. If you can reschedule, do.
- Use oral pseudoephedrine if you’re an adult with a history of flight-related ear pain: Take 120 mg at least 30 minutes before descent. Skip the nasal spray version for this purpose.
- Learn the Frenzel if you dive: It’s gentler, faster, and doesn’t require a full breath. Many dive shops and online resources offer training drills.
- Don’t trust filtered earplugs for equalization: They reduce noise, not pressure problems.
- Treat underlying allergies: If equalization has been a lifelong struggle and you also have hay fever, a stuffy nose, or eczema, the two problems may be connected.
For most people, one of the three main maneuvers, applied early and often, is enough to keep ear pressure under control. The failures tend to come from waiting too long, pushing too hard, or trying to power through congestion. If equalization remains a consistent problem despite good technique and clear sinuses, the issue is likely structural, and that’s when a specialist evaluation with tympanometry and Eustachian tube function testing becomes worthwhile.
