What is the ‘squeeze’ effect experienced by divers?

The ‘squeeze’ effect experienced by divers refers to the pressure differential that causes discomfort in air-filled spaces, such as the ears, sinuses, and lungs, as a diver descends. As a diver goes deeper underwater, the surrounding water pressure increases, which can lead to a compression effect on these air-filled cavities. If divers do not equalize the pressure in their ears or sinuses while descending, they may experience pain, discomfort, or even injury due to the inability of the air inside those spaces to adjust to the higher external pressure. This phenomenon highlights the importance of proper equalization techniques and awareness of pressure changes while diving to avoid discomfort and ensure safety during the dive. Understanding this concept is essential for divers to manage their underwater experience effectively.
