apparently its a bigger problem for people who arent heat aclimatised,
a study done on soldiers in the middle east made to do physical labour in the sun, showed soldiers who had been stationed there for some time were able to sweat twice as much as soldiers who were brought out from a british winter, the aclimatised solidiers had a more well developed sense of thirst, possibly to do with their greater rate of sweat... their heat exhaustion rate was a lot less....
friend of mine working outdoors inland in victoria regularly goes through five litres a day in summer no problems, probably because he's aclimatised
from the land of the long white clouds...
