What would happen if snorkelers were taught to equalize their ears like scuba divers, even though that's considered unnecessary?

As someone who’s spent countless hours with my face in the water-snorkeling coral reefs, paddling through kelp forests, and yes, descending on scuba tanks-I’ve thought a lot about the little things we take for granted. One of those is ear equalization. Scuba divers learn it like a reflex: pinch your nose, blow gently, and feel that satisfying pop as pressure balances in your middle ear. Snorkelers, on the other hand, rarely think about it. Why would they? You’re on the surface, right? Your ears should be fine.

But here’s the thing: teaching snorkelers to equalize-even when they’re not diving deep-could actually change how they breathe, how they move, and even how safe they are in the water. Let’s break that down.

The Physics of a Snorkeler’s Ear

When you’re floating face-down on the surface, your head is typically submerged only a few inches. At that depth, the pressure change on your eardrums is minimal-maybe a few centimeters of water column. For most people, that’s not enough to cause discomfort. But here’s where it gets interesting: the act of equalizing isn’t just about pressure. It’s about opening the Eustachian tubes, those tiny passages that connect your middle ear to the back of your throat.

When you equalize, you’re performing a gentle Valsalva maneuver (or, better yet, a Frenzel maneuver, which uses your tongue instead of your chest). This action does more than balance pressure-it actively engages muscles in your soft palate and throat. For a snorkeler, this can have a surprising side effect: it encourages a more relaxed, open airway.

The Breathing Connection

One of the biggest challenges in snorkeling-especially with a full-face mask like the Seaview 180-is maintaining a steady, low-effort breathing pattern. Any tension in your throat or chest increases inspiratory resistance, which, as the Snorkel Safety Study showed, is a key factor in Snorkel-Induced Rapid Onset Pulmonary Edema (SI-ROPE). When you’re fighting to inhale against a partially closed airway, you’re creating negative pressure in your chest. Over time, that can pull fluid into your lungs.

Now imagine a snorkeler who’s been taught to equalize. They’ve practiced opening their Eustachian tubes, relaxing their throat, and breathing calmly through their nose or mouth. That same muscle relaxation translates directly to snorkeling. Instead of clamping down when they feel a little water in the mask or a wave splashes over the snorkel top, they stay loose. Their airway stays open. Their breathing stays efficient.

What About the “Unnecessary” Part?

You’re right-most snorkelers don’t need to equalize. The pressure difference at one foot of depth is negligible. But here’s the hidden benefit: equalization drills train snorkelers to be aware of their body’s response to submersion. They learn to recognize the subtle sensation of pressure building, even if it’s minor. That awareness can be a lifesaver.

Think about it this way: one of the earliest signs of SI-ROPE is a vague sense of shortness of breath or fatigue. A snorkeler who’s tuned into their body-who knows what a normal breath feels like, and what a slightly restricted breath feels like-is more likely to notice trouble before it escalates. Equalization practice builds that body awareness.

The Practical How-To (Without Overcomplicating It)

If you’re a snorkeler reading this, you don’t need to become a scuba diver overnight. But you can borrow one simple drill:

  1. Before you enter the water, sit on the beach or pool deck and practice the Valsalva maneuver. Pinch your nose, close your mouth, and blow gently until you feel your ears “click” or “pop.” Do it five times, slowly.
  2. In shallow water, float face-down and try the same thing. Notice how your throat relaxes. Notice how your exhale feels smoother afterward.
  3. If you ever feel pressure or discomfort while snorkeling-even at the surface-stop, equalize, and check your breathing. If that doesn’t help, remove your mask, roll onto your back, and head for shore.

A Word on Full-Face Masks

With a full-face mask like the Seaview 180, equalization is still possible, but it’s slightly different. Because the mask covers your nose and mouth, you can pinch your nose through the silicone skirt if needed. However, the Seaview 180 is designed with a separate breathing chamber that keeps inhaled and exhaled air apart, which reduces CO₂ buildup and makes breathing feel more natural. That design feature also means you’re less likely to feel the urge to equalize in the first place-because you’re already breathing with less resistance.

Still, I recommend practicing the equalization drill at home with your mask on (dry, obviously) to get the feel of it. It takes ten seconds and could save you a world of discomfort.

The Bigger Picture: Safety Through Awareness

The Snorkel Safety Study made one thing crystal clear: most snorkel-related incidents don’t involve panic, inexperience, or aspiration. They involve a quiet, rapid loss of strength and consciousness due to hypoxia. The typical sequence is shortness of breath, fatigue, then diminishing consciousness-often with no visible struggle.

Teaching snorkelers to equalize won’t prevent SI-ROPE directly. But it will teach them to pay attention to their body’s signals. It will teach them to breathe slowly and deliberately. It will teach them that even at the surface, your body is responding to the water in ways you might not expect.

And that kind of awareness? That’s the foundation of every safe day on the water.

So no, you don’t need to equalize as a snorkeler. But if you learn how, you might just find yourself breathing easier, staying calmer, and enjoying the reef a whole lot more. Give it a try next time you’re out with your Seaview 180-I think you’ll feel the difference.

Stay safe, stay curious, and keep exploring.
