[pct-l] How much water to carry

[Jim Marco]

Basically, your body needs about 2 cups of water per day to cover metabolic processes. Depending on where you live, how hard you are working, and other things, you would go through another 32-256oz of water. In 100% humidity, doing hard physical labour on a 85 degree day, for example, you could go through as much as a couple gallons or more in a ten hour period. On a cool day with light walking all day, you might use three quarts or less in a 24 hour period.
 
Minor dehydration is not all that serious. Mostly, we have all experienced it. You do recover after an hour or two with no ill effects. But, water is necessary to live. You can go without food for as long as a month or two, as evidenced by people going on hunger strikes for long periods of time, especially in India. Being without water could kill you in 3 or 4 days. Less if you are sweating water out.

There is a wide variation in tolerance and what an individual is conditioned to use.
