Others emphasize the evident risk of potentially making a bad situation worse.

Wetsuits and Urination

Urinating in a wetsuit is common for many recreational divers and is generally not harmful when exposure is limited. Immersion in water, especially cold water, triggers immersion diuresis, which shifts blood into the central circulation and increases urine production. Most divers feel that urge within minutes of entering the water.
