What is a common cause of dry suit squeeze?

Dry suit squeeze occurs when the suit is unable to adequately equalize the pressure within the suit as a diver descends. When a diver descends, water pressure increases, which can compress the air inside the suit if it is not equalized properly.

If a diver fails to exhale through the nose during descent, the air trapped in the suit may not be able to expand or adjust to the increasing pressure from the water, resulting in the suit being squeezed against the body. This lack of equalization can lead to discomfort, restricted movement, and potential injury.

While improper venting during ascent and inadequate buoyancy control can lead to issues, the specific act of failing to exhale through the nose directly relates to the prevention of dry suit squeeze during descent. Understanding the importance of proper pressure equalization techniques is essential for safe diving practices and helps ensure a comfortable diving experience.
