Have you ever gone underwater and felt a strange pressure or pain in your ears?
If yes, don’t worry. This is very common for new scuba divers.
The good news is that you can usually prevent it by learning how to equalize your ears properly.
Let’s understand why it happens and what you should do.
Why Do Your Ears Hurt Underwater?
When you go deeper underwater, the water pressure around your body increases.
Your ears contain an air-filled space behind the eardrum. As the outside pressure increases, the pressure inside your middle ear needs to be balanced.
If the pressure is not equalized, you may feel:
- Pressure in your ears
- A blocked feeling
- Mild pain
- Difficulty hearing
- Sometimes sharp pain
This is commonly called ear barotrauma.
Why Does It Happen More When You Go Down?
The pressure change is greatest during the descent.
Imagine an airplane taking off or landing. Your ears may feel blocked because of changing air pressure.
Scuba diving is similar, but underwater the pressure changes as you move deeper.
That’s why your ears may feel fine at the surface but start hurting just a few meters below.
What Is Equalizing Your Ears?
Equalizing means helping the pressure inside your middle ear match the pressure outside.
One common method is the Valsalva maneuver.
You gently pinch your nose, close your mouth and gently blow against your closed nose.
You may feel a small “pop” in your ears.
That usually means the pressure has equalized.
Another technique divers learn is the Frenzel maneuver. Your instructor can teach you how to perform it correctly.
Don’t Wait Until Your Ears Hurt
This is one of the biggest mistakes beginners make.
Don’t wait until your ears are painful before equalizing.
Instead, start equalizing early during the descent and continue regularly as you go deeper.
If your ears are becoming uncomfortable, stop your descent.
If necessary, go slightly shallower and try again.
Never try to force your ears to equalize.
What If My Ears Won’t Equalize?
Stop going deeper.
Do not keep pushing down through the pain.
Try going slightly shallower and gently equalizing again.
If you still cannot equalize, it is better to end the descent or the dive than to force it.
Remember:
Pain is a signal to stop, not something you need to fight through.
What About a Cold or Blocked Nose?
A cold, allergies or nasal congestion can make equalizing difficult.
When your nose and surrounding passages are blocked, it can become harder for air to move through the Eustachian tubes and equalize the middle-ear pressure.
This is one reason divers should avoid diving when they are congested or unable to equalize comfortably.
Can Ear Pain Damage Your Ear?
Yes, forcing a descent despite ear pain can cause an ear-pressure injury, known as barotrauma.
In more serious cases, it can damage the eardrum or other structures of the ear.
That’s why proper training and listening to your body are so important.
If you experience significant or persistent ear pain, hearing loss, dizziness, bleeding, or fluid from the ear after diving, seek medical advice.
A Simple Example
Imagine you’re descending for your first scuba dive.
At the surface, your ears feel completely normal.
You descend a few meters.
Suddenly, you feel pressure.
Instead of continuing down, you stop.
You gently equalize your ears.
The pressure disappears.
You continue slowly and equalize again as needed.
That’s a much better approach than trying to push through the pain.
5 Simple Tips to Protect Your Ears
1. Equalize early
Don’t wait for pain.
2. Equalize often
Especially during the first part of your descent.
3. Descend slowly
A controlled descent gives you more time to equalize.
4. Never force it
If it doesn’t work, stop and go slightly shallower.
5. Don’t dive when you can’t equalize properly
Your instructor can help you decide what to do.
One Important Rule for Beginners
If you remember only one thing from this article, remember this:
If your ears hurt while descending, stop going deeper.
You don’t have to prove anything underwater.
A good diver knows when to slow down, stop or turn around.
Your ears are more important than reaching the bottom.
Final Thoughts
Ear pressure is a normal part of scuba diving, but pain should never be ignored.
With proper training, slow descents and regular equalization, most beginners can learn to manage the pressure comfortably.
And if your ears won’t equalize?
Stop. Go shallower. Try gently. And never force it.
That’s not being a weak diver.
That’s being a smart diver.
