What is a recommended method to prevent a delayed ear block?

The recommended method to prevent a delayed ear block is performing the Valsalva maneuver several times after flight. The Valsalva maneuver is a technique that helps equalize pressure in the middle ear. It involves taking a deep breath, closing the mouth and pinching the nose, and then gently exhaling. This maneuver can effectively balance the pressure that builds up in the ear due to changes in altitude, especially during descent when the external pressure increases rapidly.

Using this technique after flying can mitigate the risk of experiencing discomfort from a delayed ear block, as it actively opens the Eustachian tubes, allowing trapped air to escape and alleviate pressure differences. This proactive approach is especially important in preventing potential ear issues that could arise as altitude decreases upon landing.

While options like chewing gum and drinking water might help some individuals manage ear pressure by promoting swallowing and opening the Eustachian tubes, performing the Valsalva maneuver specifically targets the pressure imbalance directly. Avoiding altitude changes is impractical and not feasible for most flight operations, making the Valsalva maneuver a practical and effective strategy.
