Which maneuver is often recommended to equalize ear pressure during flight?

The Valsalva maneuver is commonly recommended to equalize ear pressure during flight because it can help open the Eustachian tubes, allowing trapped air to escape and restoring normal pressure in the middle ear. This is particularly important during ascents and descents in an aircraft, where rapid changes in altitude can create pressure imbalances. The maneuver involves taking a deep breath and gently blowing out while keeping the mouth closed and pinching the nose, which increases pressure in the throat and encourages the Eustachian tubes to open.

In contrast, sipping water can provide temporary relief by stimulating swallowing, but it is not as effective as the Valsalva maneuver for actively equalizing pressure. Shaking the head does not significantly impact ear pressure, nor does it provide a practical or effective solution. Forcefully sneezing might inadvertently equalize ear pressure for some individuals but is not a reliable method as it can also lead to risk of injury or improper technique, making it less recommended than the Valsalva maneuver.
