This summer, like many summers before it, has seen a rash of articles warning us not only that is dehydration is dangerous, but that it is also ubiquitous.

They fear that otherwise healthy adults and children are walking around dehydrated, so many that dehydration has reached epidemic proportions. Under scrutiny, however, this assertion fails to hold water. That’s the topic of this week’s Healthcare Triage.
