We hear all the time about how water is the source of life. But what if we were allergic to water? Is that even possible? I mean, our bodies are 80% water, so how could anyone be allergic to it?

It is possible, though, according to this. It's called aquagenic pruritis, and people who have it can develop a itching or tingling sensation in their skin, or even a rash, when they are exposed to water of any temperature. Symptoms can last a few minutes, or even a few hours. Some specialists argue that this isn't really an allergy but a sensitivity, possibly to some added ingredient in the water, and though I'm not an expert, I'd probably agree because to me, an allergic reaction is much more severe than something that merely causes itching.

What do you think?
