allergic symptoms to sunlight allergy
Sun allergy symptoms, causes, treatments and preventive sources: Pexels The main symptom of sun allergy is itchy skin and a stinging red spot (rashes, hives). The degree to which we turn red after being exposed to the sun for a long time, or heat rash (thermal rash) on our wrinkled bodies sweating in hot and wet weather, is not called sun allergy. Sun allergies can occur only a few minutes after exposure to the cause, or they can occur over time. If you are very sensitive to sunlight, if your clothes are thin, you may get a rash on your skin covered with clothes. Rashes can last for minutes or hours, and rarely for more than 24 hours. In general, it is common for the rash to disappear quickly when sunlight exposure is stopped.

As named “allergy,” it is important to investigate the trend of symptoms because severe sun allergy symptoms (such as widespread skin rash) can lead to hypotension, headache, nausea, wheezing and difficulty breathing, and swoon.

cause of sun allergy
Sun allergy symptoms, causes, treatments, and preventive sources: Pexels The cause of sun allergy is unknown, but it is estimated that chemicals (light allergens) produced in the body react with ultraviolet rays to cause rashes (urticaria), just as common allergies appear as antigen-antibody reactions. The average age of onset is 35 years, but there are various cases from infants to 70 years old.

sun allergy treatmentSun allergy symptoms, causes, treatments and preventive sources: Pexels Sun allergy treatment 1. UV protectionIt is important to stop sun exposure immediately when the rash begins. Disappear within minutes to hours when sun exposure is interrupted. 2. Taking antihistamine and applying antihistamine ointmentIf the rash is severe or itchy, you can take antihistamine or apply ointment to relieve the symptoms. But it relieves the symptoms and does not eliminate sun allergy. Sunlight allergy treatment 3. Photochemical therapyIf you are allergic to sunlight, you can see that your hands are unexpectedly free from rash, which can be presumed to have been “adapted” by frequent exposure. Photochemical therapy is a method of repeatedly desensitizing controlled exposure to ultraviolet light. It can be repetitive and take a long time.https://dermnetnz.org/, : https://dermnetnz.org/sun allergy preventionSymptoms, causes, treatments and preventive sources of sun allergy: PexelsPrevention of Sun Allergy 1. Avoid direct exposure between 10 a.m. and 4 p.m., when the sun is strongestOn a sunny day, it is recommended to refrain from outdoor activities and refrain from outdoor activities especially from 10 p.m. to 4 p.m., when the sun is strong all day.

Avoid direct sunlight with long clothes, sunglasses, hats, umbrellas, etc. when exposed to the sunWear clothes that cover your body as much as possible, such as long sleeves, long pants, and long skirts, choose shoes over sandals, and block sunlight from your face with sunglasses, hats, and umbrellas. It’s good to wear gloves on your hands because you get a lot of sunlight when you drive. Prevention of Sun Allergy 3. Apply sunscreen to exposed areasSun allergy symptoms, causes, treatments, and preventive sources: Pexels UVA is an abbreviation for ultraviolet A, which penetrates deep into the skin through clouds or glass, causing skin aging and light fatigue. UVB is an abbreviation for ultraviolet B. When choosing sunscreen, you have to choose a product that can block both types of ultraviolet rays and apply it carefully. Sunscreens can be removed by sweat, so you should apply them frequently.[What is SPF?] You must check SPF when choosing sunscreen. SPF stands for Sun Protection Factor and is an index of the efficacy of sunscreen. The higher the number, the stronger the ability to block UVB (ultraviolet B). For example, if you use SPF50 blocking agent, UVB can be blocked 50 times. Also, you can find a + after SPF50, which is displayed when the blocking force against UVA is above a certain standard. To sum up, SPF50+ means effective sunscreen that can cut not only UVB but also UVA.[What is SPF?] You must check SPF when choosing sunscreen.

Attach a protective film to the window glass to block ultraviolet raysUltraviolet rays can enter through glass, so you may be allergic to sunlight indoors. Typical glass windows block UVB (ultraviolet B) wavelengths, but UVA (ultraviolet A) hardly. Ultraviolet rays also exist in weather without sunlight. Therefore, if you have severe sun allergies, it is also helpful to put a film with UV protection on your house or car door.
