[pct-l] Water Consumption - desert

[Paul Robison]

While we're on the subject of drinking water at night;

Helpful tip...

... In cold weather pee before you have to...  Our body will keep our urine warm at the expense of your limbs and even in some cases your heart.

This is why when ou hold your pee in your sleeping bag you wake up freezing...  Empty your bladder and your body will be plenty warm...

... Don't hold it ... It's what vestibules are for

I read something recently about long distance runners having hydration problems while running even though they were consuming lots of fluids, but being extremely hydrated when they were done.  What happened was that all their fluids were going into their muscles while running, and they would hydrate along the way, and then that fluid would have no purpose when they were done.  That seems to explain why I'm pissing like a race horse many times at the end of the day and often into the night.  I'm going to start restricting my fluid intake in the evenings and then chug it down in the morning.
