It is possible for some people to have an allergic reaction to water, although it is extremely rare. This condition is known as aquagenic urticaria, and it causes hives or other skin reactions to develop after contact with water, regardless of its temperature or chemical composition. The reaction can be localized to the area of contact or can be generalized and affect the entire body.
Aquagenic urticaria is a type of physical urticaria, a group of hives that are caused by physical stimuli. This type of hives can also be caused by cold, heat, sunlight, exercise, and pressure.
Symptoms of aquagenic urticaria can include redness, itching, burning, and hives on the skin that comes into contact with water. In some cases, people with this condition may also experience difficulty breathing or other symptoms of an allergic reaction.
It’s important to note that this is a rare condition, and if you suspect that you have it, it’s important to see an allergist or a dermatologist for a proper diagnosis. They can conduct some tests like a water challenge, skin prick test or a patch test. They will also be able to advise you about the best course of treatment and management for your condition.
In general, most people can safely consume and come into contact with water, and water is essential for life, so if you suspect you have a water allergy, it’s important to seek medical attention.
