Sun allergy is a term used to describe a variety of conditions in which skin exposed to the sun develops an itchy red rash. Polymorphic light eruption, often known as sun poisoning, is the most prevalent type of sun allergy.
Some people have a sort of solar allergy that runs in their families. Others show signs and symptoms only when they are activated by something else, such as a drug or skin contact with plants like wild parsnip or limes.
Spring and early summer are the most common seasons for sun allergy. The skin “hardens” with continued contact with the sun over the summer months, lowering the risk of acquiring a sun allergy.
Signs and Symptoms of Sun Allergy
- Actinic prurigo: This is characterized by itchy crusted bumps (nodules).
- PMLE and photoallergic reaction: Common symptoms include a burning or itchy rash and fluid-filled blisters. The rash usually appears within two hours after sun exposure.
- Solar urticaria: People who have this reaction develop hives in minutes. Initially, you may experience burning and stinging sensations. The rash will go away in a few days to weeks. The skin may darken as a result of the reaction in some circumstances.
Causes and Risk Factors
While the specific etiology of a sun rash is unknown, UV radiation from the sun or artificial sources such as sunlamps is thought to produce a reaction in some people who are sensitive to this sort of light. It can trigger an immunological response, resulting in a rash.
The following are some of the risk factors for specific types of solar rash:
- Being a woman
- Having fair skin
- Residing in the northern hemisphere
- A history of sun rash in the family
Covering the skin and eyes with a broad-spectrum sunscreen that blocks both UV-A and UV-B rays and has at least an SPF of 30 is the best way to avoid sun-related illnesses.
- To alleviate certain symptoms, keep the afflicted regions of the skin wet.
- Wear long-sleeved clothes and a wide-brimmed hat to protect your skin.
- You might also want to consider wearing sun-protective clothing created specifically for you.
- Stay out of the sun between the hours of 10 a.m. and 2 p.m., when the sun’s rays are at their strongest.
- Stay away from recognized triggers. If you know a certain chemical, such as a prescription or contact with wild parsnip or limes, causes skin sensitivity, avoid it.
- Don’t expose yourself to a lot of sunshine all at once. Many people get sun allergy symptoms in the spring and summer when they are exposed to a lot of sunshine. Increase the amount of time you spend outside gradually so that your skin cells can adjust.
To identify the best course of treatment for your sun allergy, consult a dermatologist.
