Sun allergy is not a true allergy in the conventional sense, but rather an overreaction to ultraviolet (UV) rays, the German Health Insurance Fund has stated.
While the exact cause of sun allergy remains undetermined, it is suspected that allergens or so-called “free radicals”—aggressive oxygen compounds—play a role in its occurrence.
Symptoms
The symptoms of sun allergy include skin redness, swelling, itching, and the appearance of blisters and nodules.
If these symptoms occur, it is crucial to avoid sun exposure immediately. The affected area should be cooled using compresses with curd, ice, or chilled cucumber slices, ensuring a cloth is placed between the skin and the cooling agent.
Moreover, in severe cases, medications such as antihistamines or corticosteroid-containing drugs may be necessary.
Prevention Methods
To prevent sun allergy, it is advisable to:
Apply sunscreen with a high sun protection factor (SPF), such as SPF 50 or more.
Avoid direct sun exposure during midday hours as much as possible.
