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.

Diving After a Stroke

Carefully weigh your return to diving, and assess the risk versus reward. No studies are available that address if the areas of your brain damaged by your stroke will be more susceptible to decompression illness. If you decide to dive, seek a detailed ongoing assessment and approval from your physician. This process should include a neurological evaluation that includes the strength and weakness of major muscle groups and the degree of cerebral injury as well as an assessment and comparison of the left side and right side of your body.
