When you think about allergies, many things come to mind from food to dust and pollen - but some people suffer from more seemingly unusual allergies, like to the sun.
A sun allergy is a condition where exposure to the sun causes a reaction on the skin, with one of the most common types of allergies being polymorphic light eruption or sun poisoning, which mostly affects young, fair-skinned women.
Much like hay fever, sun allergies typically begin in the spring and affect parts of the body that are kept covered up during the winter, such as the arms or neck.
