How should a diver react if they experience discomfort related to equalization on ascent?

When experiencing discomfort related to equalization during ascent, ascending slowly can help to relieve pressure and facilitate proper equalization. As a diver ascends, it is essential for them to allow the gases in their body to expand gradually, giving their ears and sinuses time to adjust to the decreasing pressure. This approach minimizes the risk of barotrauma, which can occur if the pressure difference between the outside environment and the inner ear becomes too great.

Maintaining a slow ascent provides the diver with the opportunity to consciously attempt to equalize their ears and sinuses without pushing the ascent rate, which could exacerbate discomfort and potential injury. The key principle in diving regarding equalization is to ensure that divers never hold their breath and should continually monitor their body's responses as they ascend. By prioritizing a slow ascent, the diver can better manage any equalization issues.
