Redirect from the 7 site conversation -
If you were in a hot, tropical environment with limited water to drink, sweating inside an aluminum container (i.e. plane) for even a short amount of time, would you not become dehydrated rather quickly? Along with dehydration would come electrolyte depletion, which I believe can cause effects like confusion, delirium, etc. Perhaps even turn a person who is normally competent, intelligent and capable into something less than that - someone who repeats themselves or appears to "babble on" about things not entirely relevant to the situation.
Just a thought -
