Could people be allergic to water?

While people cannot be allergic to water itself, they can be allergic to impurities or contaminants found in water. For example, some people are allergic to certain chemicals like chlorine or fluoride added to public water supplies for disinfection and fluoridation. Others might be allergic to microorganisms or pollutants present in contaminated water sources. These allergies manifest as skin reactions, respiratory issues, or digestive problems upon contact or ingestion of the water.
