Aquagenic urticaria

Aquagenic urticaria is a rare condition where someone gets itchy and red bumps on their skin when they come into contact with water. This happens because the water makes their skin react in a funny way, even though water is usually something that people's skin can handle just fine.

Imagine you're playing outside and you accidentally bump into a cactus. Ouch! Your skin gets all red and bumpy because it's reacting to the prickly cactus. That's kind of what's happening with aquagenic urticaria, except instead of a cactus, it's water that's causing the skin to react.

People with this condition can still drink water and even shower or bathe, but they need to take extra care when doing so. They might have to use certain products that keep their skin from reacting, or they might need to take quick showers instead of long baths.

Overall, aquagenic urticaria can be a kind of annoying condition to deal with, but with proper care, people can still enjoy water activities like swimming and playing in the rain.
