If you experience symptoms of sun allergies, the first step is to seek medical attention. A sun allergy can be triggered by certain substances or exposure to sunlight. Skin biopsies and blood tests can help identify the underlying conditions. The symptoms usually disappear within hours after exposure to the sun, though it is possible to have persistent symptoms for days after exposure. If your symptoms persist even after sun exposure has ended, they may be related to a more severe medical condition like lupus or a heat rash. In that case, your physician will need to test your blood and skin for antibodies and other possible triggers. Depending on the results of these tests, you may need to undergo treatment that involves corticosteroids.
Some medications can increase your risk of developing sun allergies, such as hydroxychloroquine, an antibiotic commonly prescribed for malaria. A family history of sun allergy or a previous skin condition can also predispose you to the development of a sun allergy. Light-sensitive people may also have a higher risk of developing the condition. Genetics can also play a role in the development of sun allergies. If you’re at risk for sun allergy, consider avoiding the sun all together. Avoiding sun exposure is the most important treatment for sun allergies. However, if you can’t avoid the sun, treatment can involve using topical antihistamines and/or taking oral antihistamines.
Sun allergies can be hereditary, but can also be triggered by medications, pre-existing medical conditions, or other skin conditions. Most sun allergies affect younger people, and are more common in women. It is also more common in light-skinned people. However, those with darker skin can also develop sun allergies.
The symptoms of sun allergies usually manifest as irritated red rashes. Sometimes, symptoms can progress to blisters. Symptoms may appear immediately or within days after exposure. The most common areas affected are the neck, arms, and hands. However, these rashes can also develop on other parts of the body.
Avoiding sun exposure is the most effective way to avoid sun allergies. Wear protective clothing and stay indoors during peak sunlight hours (between 10 am and 4 pm). In addition, you should avoid sudden exposure to sunlight. Instead, increase exposure gradually. However, if you can’t avoid the sun altogether, there are treatments available.
A dermatologist will be able to determine the cause of sun allergies. Certain medications, such as non-steroidal anti-inflammatory drugs, can trigger a reaction. Drugs and cosmetics that contain these substances can also trigger a reaction. Sun allergies are not serious, but they can be uncomfortable. In some cases, they can be severe.
While some cases of sun allergy may go away without treatment, others may require steroid pills and creams to help alleviate symptoms. For more severe cases, your doctor may prescribe sun-protective clothing.
