4. Aquagenic Urticaria
Aquagenic Urticaria, commonly referred to as “water allergy,” is an extremely rare condition where the skin breaks out in painful hives upon contact with water. Whether it’s rain, sweat, or even tears, the affected person’s skin reacts, causing severe discomfort.
This strange condition can make daily activities like bathing or swimming a nightmare, and its exact cause is still unclear, although researchers believe it might be related to water interacting with the skin’s proteins.
