The body’s rejection of water is wildly counterproductive, mainly because we are made up mostly of water, our cells are filled with it and we can’t live without it. However, in almost all cases, the allergic reaction is ignited only when the outer skin contacts water. That’s how people with aquagenic urticaria can drink liquids and don’t have an adverse reaction to their own cells.
But they can be allergic to their tears if they cry, and even their own sweat, Baptist explained. Fortunately, sweat typically doesn’t cause nearly as strong a reaction as diving into a pool.
Patients can be allergic to saliva, too. While a simple peck on the cheek or lips shouldn’t be much of a problem since symptoms generally depend on dose, you could pay a high price for very passionate kissing.
