What is a Sun Allergy?

A sun allergy, also known as photosensitivity or sun sensitivity, is a condition in which the skin reacts abnormally to exposure to sunlight or other sources of ultraviolet (UV) radiation. It is characterized by a range of symptoms, including redness, itching, rash, and even blisters on the exposed areas of the skin.

Symptoms of Sun Allergy

When a person with sun allergy is exposed to sunlight, they may experience various symptoms, which can vary in severity. These symptoms may include:

• Redness and inflammation of the skin
• Itching or a burning sensation
• Rash or hives
• Blisters or raised bumps
• Swelling
• Pain or tenderness

The symptoms typically appear within a few minutes to a few hours after sun exposure and can last for several days. In severe cases, sun allergy can cause symptoms such as fever, chills, headache, and nausea.

Causes of Sun Allergy

Sun allergy is often caused by an abnormal immune system reaction to sunlight. The exact cause of this reaction is not fully understood, but several factors can contribute to the development of sun allergy, including:

• Genetic predisposition
• Exposure to certain medications or chemicals, such as certain antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), and fragrances
• Underlying medical conditions, such as lupus, dermatitis, or porphyria
• Previous sunburn or excessive sun exposure

Treatment and Prevention

While there is no cure for sun allergy, there are several measures that can help manage the symptoms and prevent flare-ups:

• Using broad-spectrum sunscreen with a high sun protection factor (SPF) and reapplying it regularly
• Wearing protective clothing, such as long-sleeved shirts, wide-brimmed hats, and sunglasses
• Avoiding direct sunlight during peak hours (usually between 10 a.m. and 4 p.m.)
• Seeking shade or using umbrellas when outdoors
• Using sun-protective lip balm
• Taking antihistamines or applying corticosteroid creams to relieve itching and inflammation
