Stop descending as soon as you cannot equalize gently; do not force it or continue downward hoping the pressure will clear. Ascend a little until equalization is comfortable, then try again; if the problem persists, end the dive.
Equalization problems in scuba diving are a reason to pause, not push through. Forcing the ears or sinuses can cause injury, while continuing to descend adds pressure. This article explains how to respond when equalization fails and why calling off a dive is the safer choice if it does not resolve.
| Sign | What it may indicate | Response |
|---|---|---|
| Ear pressure that eases with equalization | Pressure mismatch during descent | Equalize before discomfort builds |
| Ear discomfort that does not improve | Equalization is not resolving the pressure | Stop descending; ascend until pressure eases |
| Forehead or cheekbone pressure | Possible congestion or swelling | Stop diving for the day if it persists |
| Congestion or inflammation | Eustachian tubes may be difficult to open | Do not force a descent |
- 3 named areas Forehead, cheekbones, and ears are identified as possible sites of persistent pressure or discomfort.
- 1 eardrum The eardrum can bend inward when water pressure rises and the ear is not equalized.
- 0 continued descent When equalization does not improve discomfort, stop descending rather than pushing through.
What changes pressure during a scuba diving descent?
Pressure and the eardrum
During a scuba descent, water pressure rises, increasing the pressure difference across the eardrum unless the middle-ear pressure is equalized. Equalizing brings pressure inside the ears closer to the surrounding water pressure and helps protect the eardrum as the diver descends.
The eardrum can bend inward as external pressure increases. Waiting for pain or pressure before equalizing means the pressure is already acting on it; if the difference keeps growing, the eardrum may bend further or be damaged, causing barotrauma.
- Equalize early: Match middle-ear pressure with the surrounding water pressure during descent, rather than waiting for discomfort.
- Stop if discomfort persists: Pressure or discomfort in the ears, forehead or cheekbones that does not improve with equalization can indicate congestion or swelling. Stop the descent; do not push through the pressure.
Why can congestion make equalization difficult?
Congestion can make equalization difficult because inflammation or mucus may narrow the Eustachian tubes, making them harder to open and preventing pressure from balancing between the middle ear and the outside water. The forehead, cheekbones and ears are connected areas, so swelling or congestion in one or more can be felt as pressure or discomfort elsewhere.
Possible contributors include being sick, allergies, environmental irritants, certain foods, hormonal changes and not staying hydrated; tiredness can also make the Eustachian tubes harder to open. These are possible causes, not proof that any one factor is responsible for a diver’s symptoms.
When pressure is a reason to stop
Pressure or discomfort in the forehead, cheekbones or ears that does not improve with equalization may indicate congestion or swelling. Treat that as a reason to stop the dive for the day: descending without equalizing increases the pressure difference across the eardrum and can cause barotrauma.
What discomfort means you should stop descending?
Routine pressure versus a warning
Stop descending if pressure or discomfort in your ears does not improve when you equalize; do not keep going and plan to equalize later. Water pressure is already pushing the eardrum inward during descent, so waiting for pain as your cue means the pressure difference is continuing to build.
Discomfort in the forehead, cheekbones, or ears that persists despite equalization can indicate congestion or swelling in connected areas. If these symptoms do not improve, stop diving for the day—the source guidance identifies this as the normal cue, not a reason to force the descent.
- Routine pressure: Ear pressure that improves with equalization is different from discomfort that remains despite the attempt.
- Warning: Persistent pressure or discomfort in the forehead, cheekbones, or ears calls for ending the dive for the day if equalization does not help.
What should you do when equalization does not work?
Stop, ease the pressure, reassess
Stop descending if ear, forehead or cheekbone pressure is uncomfortable or does not ease with equalization; ascend until the pressure eases, then reassess rather than pushing through or continuing down. Persistent pressure is a reason to end the dive for the day.
- Pressure eases after ascending: pause and reassess before deciding whether to continue; do not resume descent while discomfort persists.
- Pressure remains despite equalization: end the dive for the day, particularly if discomfort is in the forehead, cheekbones or ears.
Looking up and extending your neck may help open the Eustachian tubes, the passages involved in equalizing ear pressure. Try that only while stopping or ascending—not as a reason to force a descent when pressure remains uncomfortable.
When does equalization advice not make a dive safe?
Limits and common mistakes
Equalization advice cannot make a dive safe when swelling or congestion keeps the Eustachian tubes from opening: repeated attempts do not reliably clear the blockage or remove the pressure difference. If the ears still hurt or feel pressured, continuing to descend can bend or injure the eardrum and cause barotrauma.
Common mistakes include waiting for pain before equalizing and treating unresolved pressure in the forehead or cheekbones as an ear-only problem. Ear, forehead and cheekbone symptoms that do not improve with equalization can point to congestion or swelling in connected areas; persistent symptoms are a reason to stop diving for the day.
- Equalization works: Continue only while the pressure can be matched without persistent discomfort.
- Equalization fails or discomfort remains: Stop the descent rather than making repeated attempts while going deeper.
- Forehead or cheekbone pressure persists: Treat it as a possible sign of congestion, not simply an ear problem, and end diving for the day.
How can divers protect their ears on the next descent?
Divers can protect their ears on the next descent by practising equalization during training, equalizing before discomfort starts, looking up with the neck extended if that position helps, and stopping the descent when congestion prevents comfortable equalization. These steps help address pressure changes before they become painful.
Equalize early and repeatedly rather than waiting for pain or pressure to prompt you: as you descend, the eardrum is already bending inward under the increasing water pressure. Practising your chosen equalization technique during training makes it familiar before the dive, when you can focus on gentle, timely use rather than figuring out the method underwater.
When to pause or stop
Looking up and extending your neck may help open the Eustachian tubes; use that position only if it makes equalization easier. If you cannot equalize comfortably, pause the descent rather than forcing it. Congestion or swelling can obstruct the connected passages, so do not start or continue a descent when it prevents comfortable equalization.
Pressure or discomfort in the ears, forehead, or cheekbones that does not improve with equalization can indicate congestion or swelling. Treat that as a reason to stop diving for the day, not as a challenge to push through: continuing without equalizing allows the pressure difference to build and can injure the eardrum.

Key takeaways
- Equalization matches pressure inside the ears to the surrounding water pressure.
- Congestion, inflammation, or mucus can make Eustachian tubes difficult to open.
- Persistent forehead, cheekbone, or ear discomfort is a reason to stop diving for the day.
- Do not keep descending against pain or ineffective equalization; the eardrum can be damaged.
