You've probably heard of peanut, pet dander, and even pesky ragweed allergies. But did you know that people can be allergic to water? According to a 2016 BBC report, there have been 35-50 known cases of water allergy, also called Aquagenic Urticaria, in the world. The first documented case appeared in 1963 when a 15-year-old girl's body broke out with hives after only a few minutes of water-skiing.
Because this allergy is so rare, there is little scientific understanding of the condition. However, scientists have found that water allergy is more common in women and usually presents itself during puberty. According to Dr. Sarah Jarvis, a General Practitioner and BBC Radio 2's medical expert, "some people are so allergic to water that even their tears or their sweat can cause them to come out in a rash."
