Dehydration & Diving

[FreediveWI]

Before a deep scuba dive it is not uncommon for me to consume close to a gallon before I dive. A P-valve is just standard gear. A general rule of thumb for deep diving is to have everyone urinate right before the dive. If it's not clear, you don't dive.

In scuba you can get bent by not being hydrated, no big news there, and in freediving you are at greater risk of shallow water blackout if not properly hydrated.

Kirk Krack, senior trimix instructor trainer for IANTD and freediving trainer of champions, used to recall his deep dives in Cayman, to depths of 500', by the number of times he urinated underwater rather than by the amount of time he deco-ed. ;D
