Not at all, the study shows that for this unusual population, which consists
of "concentrated urine outputs, high incidence of kidney diseases and high
hematocrit ratios". This is obviously atypical. The study also says that
increased drinking improved thermoregulation, but this was again in an
envoronment (very high heat, very high exercise) that most of us dont
encounter in our daily lives. To the best of my knowledge, its NEVER been 45
Deg C in the Uk for example, or not since dinoasaurs roamed the planet.
Maybe they could have used this advice?
So the study doesn't serve as a pointer to anything.
