Understanding Sun Allergies and Their Causes

Sunshine is usually associated with warmth, joy, and fun outdoor activities. However, for some individuals, exposure to the sun can result in uncomfortable and sometimes even debilitating symptoms. Sun allergies, also known as photosensitivity or photodermatitis, are immune system reactions to sunlight that can cause a range of symptoms such as redness, itching, hives, and blisters.

There are different types of sun allergies, including polymorphic light eruption (PLE), solar urticaria, and photoallergic eruption. PLE is the most common form and typically presents as an itchy rash on areas of the body that have been exposed to the sun.
