swim is a terrific , humiliated - encroachment exercise , which is why plenty of mass make it part of their even fitness regimen . But if you expend enough clock time in the pee , you might notice that your bladder seems more active than when you ’re on ironic land . Onestudyfound that a 110,000 - gallon pool stop some 8 gallon of urine . Does being immersed in water suddenly increase your itch to go ?
Turns out the answer is yes . Thereasonis something known asimmersion diuresis , a term for the body increase its pee production in reply to being submerged in piss . Your parentage vessels constrict , moving bloodline to your home organs . That raises your blood pressure , which can increase activity in your kidneys because the body wants to release fluid to compensate for the arterial changes . The net result : the itch to pee .
Your kidney can also act in response to pee pressing , which can increase when you plunk further down . Again , blood insistency is increase , and your kidney are filter out more fluid .
Immersion diuresis increases with cold pee , which makes it more of an issue in undetermined bodies rather than heated pools — though simply being in the pool for prospicient periods of time can leave in a normal need to urinate . Nerves can have an effect , too . Plenty of Olympic natator haveadmittedto peeing in consortium .
Peeing with an athletic legacy on the line is one thing . choose whether just to go while playing with a puddle bean in a friend ’s above - ground pool is another . If you need to go , should you go ? In open water , it ’s not really an issue . great deal of distance bather let loose . In a swim puddle , theansweris trickier . While some bacteria exists in pee , it ’s in the main not enough to make you or others ill , particularly when a pool is being treated with chlorine . It ’s more about manners . Since it ’s somewhat underbred to force others to swim around in a mixture of pool water and your own body ’s barren , you should probably find the bathroom .
