If your ears hurt while scuba diving, don’t ignore it. Ear discomfort is one of the most common challenges for new divers, but the good news is that equalizing your ears is a skill that can be learned. With the right techniques and a little practice, most people can descend comfortably and safely.
In this guide, we’ll explain why equalizing is important, why some people struggle with it, and the best ways to make your next dive pain-free.
Why Do Your Ears Hurt When You Dive?
As you descend underwater, the pressure around you increases rapidly. In fact, the biggest pressure change you’ll experience during a dive happens within the first 10 meters (33 feet).
Your middle ear contains air, and as the surrounding water pressure increases, that air space becomes compressed. If you don’t equalize, pressure builds against your eardrum, causing discomfort or pain.
Equalizing allows fresh air to travel through the Eustachian tubes into your middle ear, balancing the pressure on both sides of the eardrum.
What Happens If You Don't Equalize?
Ignoring ear pain underwater can lead to injuries ranging from mild discomfort to serious ear barotrauma.
Possible consequences include:
- Ear pain
- Temporary hearing loss
- Dizziness or vertigo
- Fluid or bleeding behind the eardrum
- A ruptured eardrum in severe cases
The golden rule is simple:
Pain is never normal during a descent.
If your ears hurt, stop descending immediately.
Why Is Equalizing Difficult for Some People?
Everyone’s anatomy is slightly different, so equalizing isn’t equally easy for everyone. Common reasons include:
You’re waiting too long
Many beginners only try to equalize once they feel pain. By then, it becomes much harder.nstead, start equalizing before you feel discomfort—even before your head goes underwater if needed.
You’re descending too quickly
A fast descent gives your ears less time to adjust. Take your time and descend slowly while equalizing every half meter to meter.
Congestion
Colds, allergies, sinus infections, or blocked nasal passages can make equalization nearly impossible. If you can’t equalize on land, don’t dive.
Stress
When you’re nervous, your muscles tense up and breathing becomes shallow. This can make equalizing more difficult. Relax, breathe slowly, and don’t rush
The Most Common Equalization Techniques
1. Valsalva Maneuver
This is the method most divers learn first.
- Pinch your nose.
- Close your mouth.
- Blow gently against your pinched nose.
The key word is gently. Blowing too hard can actually cause injury.
2. Swallowing
Swallowing naturally opens the Eustachian tubes. Many divers combine swallowing with gently pinching their nose.
3. Moving Your Jaw
Try:
- Wiggling your jaw side to side
- Pretending to yawn
- Moving your lower jaw forward
These movements can help open the Eustachian tubes.
4. Frenzel Technique
Many freedivers prefer the Frenzel technique because it uses the tongue instead of chest pressure. It takes more practice but requires less effort and often works better at greater depths.
Tips to Make Equalizing Easier
Here are a few habits that can make every dive more comfortable:
- Start equalizing before you descend.
- Equalize early and often.
- Descend feet first if possible.
- Use the descent line to control your speed.
- Stay relaxed and breathe normally.
- Stop if you feel pressure.
- Ascend slightly if equalization isn’t working, then try again.
- Never force it.
Can Some People Never Equalize?
Very few people are physically unable to equalize. Most difficulties improve with practice, proper technique, and patience. If you consistently struggle despite trying different techniques, it’s worth speaking with an ear, nose, and throat (ENT) specialist before diving again.
What Should You Do If Equalizing Doesn't Work?
Don’t panic. Instead:
- Stop descending.
- Signal your buddy or instructor.
- Ascend a little until the discomfort eases.
- Try equalizing again.
- Continue only when your ears feel comfortable.
If it still doesn’t work, end the dive. There will always be another opportunity to dive.
How We Help at Fast Manta
At Fast Manta, we never rush descents. Our instructors take the time to help each diver equalize comfortably before continuing underwater. Remember: every diver equalizes at their own pace. Taking an extra minute at the surface is far better than pushing through pain.
Equalizing is one of the most important skills you’ll learn as a diver. It isn’t a race, and there’s no prize for being first to the bottom.
Listen to your body, descend slowly, and equalize early and often. With practice, it becomes second nature—and you’ll be able to focus on what really matters: enjoying the incredible underwater world.
