Abstract. Background: Polymorphic light eruption (PLE) is a very common condition whose pathogenesis may involve immunological abnormalities. Vitamin D sufficiency is thought to be important for normal immune function.
Why have I suddenly become allergic to the sun?
Research shows that, over time, repeated exposure to UV radiation can cause the body to develop an immune response to the sun, similar to environmental pollen and hay fever. This is because sun exposure can produce changes in skin cells that the body’s immune system may identify as being foreign, or abnormal antigens.
