Water
As Philip Halverson, MD, of Allergy & Asthma Specialists in Minneapolis, Minnesota has explained, it’s quite common for some people to break out in hives after jumping in a pool, lake, or even shower.
Why? It might seem strange, but some people are allergic to water. This is indeed a bizarre allergy. Even though it is not very common, aquagenic urticaria is a condition that causes urticaria, very itchy and even painful at times, as soon as you get in contact with water.
Until present, there’s not enough information about what could be causing this strange allergy, however, the researchers assume it’s a substance dissolved in the water that makes your immune system react by showing symptoms.
