To counteract pressure build-up in the ear, which of the following actions is NOT recommended?

To counteract pressure build-up in the ear, ignoring the pressure is not recommended because it does not alleviate the discomfort or potential pain associated with barometric pressure changes. In fact, ignoring the sensation can lead to further complications, such as a failure to equalize the pressure, which may result in more significant issues like barotrauma.

Conversely, actions such as yawning, swallowing, and tensing the throat muscles are effective methods for equalizing ear pressure. Yawning helps open the Eustachian tubes, facilitating pressure equalization. Swallowing activates muscles in the throat, also aiding in unblocking the Eustachian tubes. Tensing throat muscles, such as during a Valsalva maneuver, can create a pressure change that promotes the equalization of pressure in the middle ear. Therefore, adopting proactive measures to relieve pressure is crucial for maintaining comfort and ear health during altitude changes.
