Dealing with the heat

[OakLeaf]

... For you, it's a lot - for me, in that kind of heat and humidity, it would probably be spot on. I sweat a liter an hour when it's 75° out.

IMO, the best way to avoid hyponatremia is NOT to avoid drinking water when you need it - it's to replace electrolytes along with water.

Especially when someone's acclimating to the heat. Part of heat acclimation is that the sweat glands spare more sodium. Another part is that you learn to sweat more. So the better acclimated you are, in general, the more water and the less electrolytes you need. But still, everyone sweats at a different rate.
