Water pressure does not affect people that way. The only cavities in the body are the lungs, sinuses and the windpipe between them. All other parts are water filled and will equalize to the ambient pressure without significant dimensional change. The record scuba dive (no pressure protection) is to 330m. (
Deep diving - Wikipedia, the free encyclopedia) Pressure on a person with un-equalized cavities (person not breathing from ambient pressure source), will cause tissue damage and bleeding from broken blood vessels near the cavities, but not breaking of bones. (However, the free dive - breath-hold - record is 214m (
Free-diving - Wikipedia, the free encyclopedia), so with training, even breath-hold is not much of a limit.)
That could be one reason.
Sorry for my very rude English,
