What is dry suit squeeze associated with?

Dry suit squeeze is primarily associated with pressure changes within the dry suit as a diver descends into deeper water. As divers go deeper, the surrounding water pressure increases. If the dry suit is not adequately vented or if the diver has not equalized the air volume inside the suit, the increased external pressure can compress the suit against the body, leading to physical discomfort or even injury. This condition occurs because the air inside the suit cannot expand to match the decreasing volume with increasing pressure, creating a situation where the suit can constrict around the diver and restrict movement or circulation.

Thus, understanding how pressure dynamics work in conjunction with the dry suit is critical for ensuring diver safety, as it highlights the importance of proper suit ventilation and the need for divers to manage the air inside their dry suits effectively during their descent and ascent.
