SUN ALLERGY Meaning and
Definition
-
Sun allergy, also known as photosensitivity or sun sensitivity, refers to a condition in which an individual exhibits an abnormal response upon exposure to sunlight or certain types of ultraviolet (UV) radiation. It is characterized by various symptoms that can range from mild to severe reactions involving the skin.
Typically, a sun allergy occurs due to an immune system reaction to the UV radiation from the sun. The immune system mistakenly identifies these rays as harmful and triggers an inflammatory response. This response may result in symptoms such as redness, itching, rash, hives, or even blisters on the exposed areas of the skin. In some cases, sun allergies can also cause symptoms beyond the skin, including headache, dizziness, nausea, or fatigue.
There are different types of sun allergies, including polymorphous light eruption (PMLE), actinic prurigo, solar urticaria, and photoallergic eruption. PMLE is the most common form, characterized by itchy or burning rashes within hours of sun exposure, usually affecting individuals with fair skin. Actinic prurigo is a hereditary condition in which severe itching and skin lesions occur after sun exposure. Solar urticaria causes immediate hives or welts upon exposure to sunlight, while photoallergic eruption occurs when the skin reacts to certain medications or chemicals that are activated by UV radiation.
Preventive measures for sun allergies involve protecting the skin from direct sunlight through the regular application of sunscreen with high sun protection factor (SPF), wearing protective clothing, hats, and sunglasses, and seeking shade during peak sunlight hours. In severe cases, where symptoms persist or worsen, medical attention should be sought for diagnosis and treatment, which may involve antihistamines, corticosteroids, or phototherapy.

Etymology of SUN ALLERGY
The word "sun allergy" is a compound formed by the combination of two words: "sun" and "allergy".
- "Sun" comes from the Old English word "sunne" and is derived from the Proto-Germanic word "sunnon". It is related to the Old Norse word "sól", Dutch word "zon", and German word "Sonne". Ultimately, the word can be traced back to the Proto-Indo-European root "*sóh₂wl̥", meaning "the sun".
- "Allergy" originated in the early 20th century and is derived from the Greek word "allergḗs" meaning "altered reaction". It combines two Greek words: "állos", meaning "other", and "ergós", meaning "activity" or "reaction".
Therefore, "sun allergy" refers to an altered reaction or hypersensitivity to the sun.
