SUN ALLERGY.

 Summer is the season of fun and relaxation, but for some people, it can be a nightmare. Sun allergy, also known as photosensitivity, is a condition where the skin reacts abnormally to exposure to sunlight. This can cause redness, itching, rashes, and in severe cases, blisters and hives. In this article, we will discuss the causes, symptoms, and prevention of sun allergy.

Causes of Sun Allergy

Sun allergy occurs when the immune system overreacts to UV radiation from the sun. There are different types of sun allergy, and the causes can vary from person to person. Some of the common causes of sun allergy are:

1. Polymorphic light eruption (PLE): This is the most common type of sun allergy, which occurs when the skin is exposed to UV radiation after a long period of time without sun exposure. This can cause red, itchy, and bumpy rashes on the skin.

2. Photoallergic eruption: This type of sun allergy occurs when the skin reacts to UV radiation in combination with certain medications or chemicals. The reaction can cause blisters, hives, and other severe skin symptoms.

3. Actinic prurigo: This is a rare type of sun allergy that occurs due to genetic factors. It causes itchy, red rashes on the face, neck, and hands, and can be aggravated by exposure to sunlight.

Symptoms of Sun Allergy

The symptoms of sun allergy can vary depending on the type and severity of the condition. Some of the common symptoms are:

1. Redness and itching: This is the most common symptom of sun allergy. The affected area may become red and itchy, and in some cases, small bumps or blisters may appear.

2. Swelling and hives: In severe cases, sun allergy can cause swelling and hives on the skin. This can be accompanied by pain and discomfort.

3. Fever and chills: In rare cases, sun allergy can cause fever and chills, which are signs of an allergic reaction.

Prevention of Sun Allergy

Prevention is the best cure for sun allergy. Here are some tips to prevent sun allergy:

1. Use sunscreen: Applying a broad-spectrum sunscreen with a high SPF can help protect your skin from UV radiation. Make sure to reapply every two hours, especially if you are swimming or sweating.

2. Wear protective clothing: Wearing long-sleeved shirts, pants, and hats can provide extra protection from the sun.

3. Avoid peak sun hours: Try to avoid being outside during peak sun hours (10 am to 4 pm), when the sun’s rays are the strongest.

4. Check your medications: If you are taking any medications, check with your doctor to see if they can cause photosensitivity.

In conclusion, sun allergy can be a painful and uncomfortable condition, but it can be prevented with proper precautions. If you experience any symptoms of sun allergy, consult a dermatologist for proper diagnosis and treatment. With the right care, you can enjoy the summer sun without worrying about sun allergy.
