Re: [at-l] Water Water Water

Folks,

Can you validate the following dehydration trivia?

The human body, during heavy exertion, can sweat 2 liters of
water per hour.

The human body can absorb 1 liter of water per hour.

Therefore, during extended periods of heavy exertion, you can become
dehydrated even though you are drinking like crazy.  Long rest periods
are required in order to rehydrate.

Can't remember where I saw this.  Backpacker maybe.  Anybody
know if its fact or fiction?

Thanks,
Stargazer
