It’s possible to be allergic to water!

It’s a rare condition known as aquagenic pruritis, and it causes mild to severe discomfort after coming in contact with water of any temperature!

The condition is extremely rare and causes burning, itching, or a prickly sensation all over the body. Symptoms usually last for a couple hours then disappear. Some scientists believe that rather than an allergy, it is skin sensitivity to chemicals in the water that cause the discomfort.

Treatment exists, but because the causes are still uncertain, doctors have a difficult time treating the disease.
