What is a method for preventing a sinus squeeze during diving?

Preventing a sinus squeeze during diving relies heavily on the ability to equalize pressure in the sinuses with the surrounding water pressure. Halting during descent or ascent for pressure balance is a key technique to manage this equalization. By pausing and allowing time to perform specific maneuvers, such as pinching the nose and blowing gently, divers can help equalize the pressure in the sinuses and prevent the painful condition known as sinus squeeze.

This technique is essential because it provides an opportunity for divers to assess their ability to equalize. If they feel discomfort, they can take further steps to relieve pressure before continuing their descent or ascent, thus avoiding potential injury to the sinuses.

In contrast, diving with nasal congestion can lead to blockages that hinder equalization, skipping ascent procedures can exacerbate pressure issues, and using decongestants may provide temporary relief but does not replace the necessity of proper equalization techniques during the dive itself. Therefore, pausing for pressure balance is the most effective method for preventing a sinus squeeze.
