Ensuring proper equalization during descent is essential for divers to prevent discomfort and potential injury to their ears. The correct approach involves practicing equalization techniques frequently and starting the process early in the descent. This proactive method helps to match the pressure in the middle ear with the increasing water pressure outside.

Starting equalization early allows divers to adjust gradually, making it less likely to encounter difficulties later when they are deeper underwater. Divers can use techniques such as the Valsalva maneuver or the Frenzel maneuver, which are effective methods for equalization. Regular practice of these methods can increase confidence and skill, enhancing overall comfort and safety while diving.

Choosing to only equalize when experiencing pain can lead to severe discomfort and injury, such as barotrauma. Similarly, trying to descend faster by avoiding equalization altogether poses significant risks to ear health. Lastly, relying solely on the mouth for equalization is not advisable, as effective equalization often requires utilizing the diaphragm and nasal passages for pressure management.
