Equalizing your ears is the very first skill every diver learns, and it is what lets you descend comfortably without pain. As you go deeper the water pressure pushes on your eardrums, and equalizing simply adds a little air to the spaces inside your ears and sinuses to balance that pressure out. Done early and gently, it is completely painless and quickly becomes second nature. Master it and the descent onto reefs like El Museo becomes a smooth, easy glide instead of something to worry about.
Why your ears feel it
Behind each eardrum is a small air-filled space connected to the back of your throat by a narrow tube. On land these spaces stay balanced on their own, but underwater the growing pressure presses the eardrum inward, which is the pinch you feel as you descend.
Equalizing pushes a little air up those tubes to fill the space and press the eardrum back to neutral. The pressure change is fastest in the first few meters, which is exactly why you start equalizing right away.
The main techniques
There are a few gentle ways to equalize, and most divers settle on one or two favorites. Try them and see which feels easiest for you.
- Pinch and blow: gently pinch your nose closed and softly blow against it until you feel your ears pop. This is the most common method.
- Swallow: swallowing or moving your jaw side to side opens the tubes naturally.
- Wiggle your jaw: pushing your lower jaw forward and down can open the airways on its own.
- Combine them: many divers pinch, blow gently, and swallow at the same time for an easy pop.
Early, often, gently
The golden rule is to equalize early and often, before you ever feel discomfort. Start on the surface, equalize again every meter or so on the way down, and stay ahead of the pressure rather than chasing it.
Never force it. If your ears will not clear, stop, rise a meter to relieve the pressure, and try again gently. Pushing hard against a blocked ear can cause injury, so patience always wins over power.
If it will not clear
Some days your ears are simply slower, especially if you have a cold or congestion. If one side stubbornly refuses to equalize, ascend slightly, tilt that ear toward the surface, and try again, since the change of angle often helps.
Never dive with a heavy cold, and let your guide know if you are having trouble; there is no rush and no prize for descending fast. Our warm, calm water and patient instructors make Isla Fuerte an easy place to learn this at your own pace, and you can read more starter tips in our more guides.
