11 Tips for Easy Equalization

Listen for the "pop." Before you even board the boat, make sure that when you swallow you hear a "pop" in both ears. This tells you both eustachian tubes are opening.

Start early. Several hours before the dive, begin gently equalizing your ears every few minutes. Chewing gum seems to help because it makes you swallow often.

Equalize at the surface. "Prepressurizing" at the surface helps most divers get past the critical first few feet of descent. It may also inflate your eustachian tubes so they are slightly bigger. Not all medical authorities recommend this, however. The lesson here is to pre-pressurize only if it seems to help you, and to pressurize gently.

Descend feet first. Studies have shown a Valsalva Maneuver requires 50 percent more force when you're in a head-down position than head-up.

Look up. Extending your neck tends to open your eustachian tubes.

Use a descent line. Pulling yourself down an anchor or mooring line helps control your descent rate more accurately. A line also helps you stop your descent quickly if you feel pressure.

Stay ahead. Equalize often, trying to maintain a slight positive pressure in your middle ears. Don't wait until you feel pressure or pain.

Stop if it hurts. Your eustachian tubes are probably locked shut by pressure differential. Ascend a few feet and try equalizing again.

Avoid milk. Some foods, including milk, can increase your mucus production.

Avoid tobacco and alcohol. Both tobacco smoke and alcohol irritate your mucus membranes, promoting more mucus that can block your eustachian tubes.

Keep your mask clear. Water up your nose can irritate your mucus membranes, which then produce more of the stuff that clogs.
