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.

The Beat Goes on in Southwest New Providence

When I began working as a dive photojournalist for Skin Diver magazine in the mid-1980s I was like other photojournalists of that era, Rick Frehsee and Michael Lawrence. We all lived near enough to Miami International Airport so we could easily fly to Caribbean destinations to do articles. Our small posse was frequently sent on assignment to “the islands.”
