Why is it important to equalize pressure while descending?

Equalizing pressure while descending is crucial because it helps prevent ear barotrauma, which is damage to the inner ear caused by differences in pressure. As divers descend, the pressure increases, and without equalization, the pressure on the outer ear can become significantly greater than the pressure in the inner ear. This imbalance can lead to pain, discomfort, and even potential injuries like ruptured eardrums if not addressed.

Maintaining comfort during the dive is also vital for safety and enjoyment; discomfort can Distract a diver from focusing on their surroundings and adhering to safe diving practices. Therefore, regular equalization is a fundamental skill for divers to ensure their ears and sinuses can adjust naturally to the changing pressure as they go deeper underwater.
