Allergy to the sun: causes, symptoms, and management

Sun allergy, also known as photosensitivity, is a condition in which the skin reacts abnormally to sunlight.

While many people enjoy soaking up the sun’s rays, individuals with sun allergies may experience discomfort and adverse reactions upon exposure to sunlight. This article delves into the causes, symptoms, and management of sun allergy to help individuals better understand and cope with this condition.
Allergy to the sun: causes, symptoms, and management


Sun allergy can be triggered by various factors, including:

Genetics: Some individuals may inherit a predisposition to sun sensitivity from their parents.

Medications: Certain medications, such as antibiotics, diuretics, and nonsteroidal anti-inflammatory drugs (NSAIDs), can increase the skin’s sensitivity to sunlight.
Chemicals: Exposure to certain chemicals found in fragrances, cosmetics, and sunscreen ingredients can cause a phototoxic reaction when exposed to sunlight.
Medical Conditions: Conditions like lupus, polymorphous light eruption (PMLE), and solar urticaria can also contribute to sun allergy.

The symptoms of sun allergy can vary from mild to severe and may include:

Redness: The skin may become red or inflamed upon exposure to sunlight.

Rash: Itchy or painful rashes, bumps, or blisters may develop on the skin.

Swelling: Some individuals may experience swelling or hives on the affected areas.

Burning Sensation: The skin may feel like it’s burning or stinging.

Peeling: In severe cases, the skin may peel or flake after sun exposure.


While sun allergy cannot be cured, there are several strategies to manage and minimize its symptoms:

Sun Protection: Avoiding direct sunlight during peak hours (10 a.m. to 4 p.m.) and wearing protective clothing, hats, and sunglasses can help reduce sun exposure.
Sunscreen: Use broad-spectrum sunscreen with a high SPF (Sun Protection Factor) regularly, even on cloudy days.
Medications: Over-the-counter antihistamines or corticosteroid creams can help alleviate itching and inflammation.
Phototherapy: In some cases, controlled exposure to sunlight or phototherapy treatments under medical supervision may desensitize the skin and reduce symptoms over time.
Identify Triggers: Keep a diary to track activities, medications, and skincare products that may exacerbate symptoms, and avoid them when possible.
Consult a Dermatologist: If symptoms persist or worsen, consult a dermatologist for further evaluation and personalized treatment options.
Sun allergy can be a challenging condition to manage, but with proper precautions and lifestyle adjustments, individuals can minimize their symptoms and enjoy outdoor activities more comfortably.
