Our country is a country with no shortage of sunshine. However, sometimes this sun can cause minor problems for our skin. Have you ever experienced redness, itching, or small blisters on your skin after going out in the sun? For some people, this can be a bit severe. Today we are going to talk about the allergy caused by this sun, that is , Sun Allergy .
What is this sun allergy? (Sun Allergy)
Simply put, a sun allergy is when your skin reacts to sunlight by developing a rash . Sometimes this rash can be accompanied by other symptoms. For some, it can be very mild, but for others, it can be severe and affect your ability to function normally. To be precise, this condition occurs when our skin cells become sensitive to certain things in the sun (especially ultraviolet rays).
What are the main types of sun allergy?
Now, there's no one way to be allergic to the sun. There are several types, depending on the nature of the rash, the cause, and the people most commonly affected. Let's see what they are.
Actinic Prurigo
This is a condition that causes raised bumps (papules) or small nodules (nodules) on the skin. Sometimes, the rash can spread to areas that have not been exposed to the sun. It is especially common in people of Latin American and American Indian descent, who have darker skin tones. There is also a genetic link to this condition, called ``Actinic Prurigo''. It is also called ``Hydroa Aestivale'' and ``Hutchinson's Summer Prurigo''.
Photoallergic Reaction
This is a little different. What happens here is that some chemical on your skin reacts with sunlight. Think about it, some medications you use, sunscreen, makeup, perfumes, etc. can cause this. It can take a few hours or a few days for symptoms to appear.
For example, imagine that Nimali Akka went to the beach one day after applying her new sunscreen. A few hours later, her neck and arms turned red, and small blisters appeared, which started itching a lot. It was only when she showed them to the doctor that she learned that something in the sunscreen had reacted with the sun and caused a photoallergic reaction.
Polymorphous Light Eruption (PMLE)
This type of PMLE is more common in women, people with fair skin, and young people (especially between the ages of 15 and 30). It appears as small, scaly spots or blisters on the skin a few hours after sun exposure. This is the most common type of sun allergy.
Solar Urticaria
This is when you get a rash called `hives` within minutes of being exposed to the sun. It's like getting a 'sun rash'. Symptoms can range from mild to severe. Sometimes, it can even develop into a severe allergic reaction called `anaphylaxis`, which can be life-threatening.
Who is more likely to develop allergies to this sun?
Actually, anyone can develop a sun allergy. But we've already talked about how certain types of allergies are more likely to affect people with lighter or darker skin tones. Also, if someone in your family has this condition, you're more likely to develop it too. That means there may be a genetic factor.
Additionally, some medications you take can cause a ``Photoallergic Reaction'', which is sensitivity to sunlight. Check to see if you are taking any of the following medications:
- Antibiotics
- Antifungals
- Antihistamines (some types)
- Cholesterol-lowering drugs
- Diuretics (medicines that help remove water from the body)
- Types of hormones (for example, birth control pills)
- Nonsteroidal anti-inflammatory drugs (NSAIDs) (painkillers)
- Retinoids (medicines used to control acne and skin aging)
This allergy is usually seen more frequently during the spring (or early summer in our country) and early summer, when people start to be exposed to more sunlight. However, with continued exposure to the sun, sometimes the skin becomes a little more accustomed to it and this reaction can decrease.
Why do people get allergic to the sun? What is the cause?
To be honest, scientists still don't know exactly what causes sun allergies. Some studies suggest that it may be inherited . Others say that it's caused by chemicals called histamines released by our bodies when exposed to the sun or by changes in our immune system . There are likely several factors that contribute to the type of skin reaction that occurs. So it's a bit complicated.
What are the symptoms of a sun allergy?
Symptoms of a sun allergy can appear within minutes, hours, or days after exposure to the sun. These symptoms can range from mild to severe. It depends on factors such as:
- Amount of skin exposed to the sun
- Time in the sun
- Sunlight intensity (rays)
- The type of sun allergy you have
The rash usually only appears on sun-exposed areas, but sometimes it can appear on other parts of the skin.
Symptoms of a rash caused by a sun allergy may include:
- Papules, nodules, blisters, or hives on the skin
- Itching
- Maybe fluid oozing from the wound
- Skin redness
- Skin peeling or crusting
- Burning or stinging sensation
- Swelling
Very rarely, a sun allergy can cause systemic symptoms that affect the entire body. These include:
- Headache
- Light-headedness or fainting
- Nausea and vomiting
- Wheezing or shortness of breath
- Anaphylaxis, a potentially life-threatening condition, can occur in the case of solar urticaria.
Is this sun allergy contagious?
No, not at all. A rash caused by a sun allergy is not contagious . That means you cannot spread it to someone else.
How do you know if you have a sun allergy?
If you suspect that you are experiencing these types of problems when you go out in the sun, the best thing to do is to see your family doctor. Or, even better, see a dermatologist .
The doctor diagnoses this condition based on things like:
- Talk to you about your symptoms (how long they have been present, what time they come on, how long they have been present, etc.).
- Research the medications and skin care products you use.
- Light testing is done. This involves shining light onto your skin from a few centimeters away using different light sources (artificial and natural), with different wavelengths and intensities. This can help determine exactly what kind of light your skin reacts to. Sometimes, patch testing is also done in conjunction with light testing . This involves placing a small patch of the suspected chemical on your skin.
- Rarely, the doctor may take a small piece of skin and perform a skin biopsy , which involves examining skin cells under a microscope.
What are the treatments for sun allergy?
The best and most effective treatment for sun allergy is to avoid exposure to the sun . That's the main thing.
However, for those for whom it is not practical to always avoid the sun, or for those who experience severe reactions, these treatments may provide relief:
- Antihistamines: Examples include Loratadine, Fexofenadine, and Cetirizine. These control symptoms such as itching and hives.
- Corticosteroids: For example, medications like prednisone. These are usually given for a short period of time, in severe cases.
- Creams to reduce itching: You can use things like calamine lotion to keep the skin moisturized and reduce itching.
- Omalizumab vaccine: This vaccine is used in some severe cases.
- Phototherapy: This is a longer-term treatment. It involves gradually exposing the skin to sunlight (or artificial UV light) under controlled conditions to try to reduce the sensitivity of the skin. It's like 'picking the thorn where it's bitten'.
How can you reduce the risk of an allergic reaction to the sun?
As we've discussed before, scientists still don't fully understand why this sun allergy occurs, so it's hard to say exactly how to prevent it completely. That is, we can't guarantee that if we do this, it won't happen again .
However, there are things we can do to reduce the likelihood of this happening and to lessen its impact if it does. These are what we'll talk about next.
What kind of future can someone with a sun allergy expect?
The condition of people with sun allergies often varies from person to person. For some people, the condition will outgrow itself over time. That is, as they get older, or after a few years, these problems will disappear.
But, many people have to live with these symptoms for 10 to 15 years, maybe even longer. It can be a bit annoying.
A rash caused by a sun allergy usually goes away within a few hours or days after you leave the sun. However, sometimes the rash can last for up to two weeks. The best part is that unless you scratch and injure yourself, this rash usually doesn't cause scarring .
If I have a sun allergy, how can I take care of myself?
If you also have a sun allergy, you can prevent or reduce the occurrence of these annoying conditions by following these tips:
- As spring and summer begin (in our country, with the dry weather that follows), gradually increase your time in the sun. Don't stay in the sun for too long at once. This will give your skin a chance to gradually adjust to the sun.
- Avoid sun exposure as much as possible during peak hours, between 10 a.m. and 4 p.m. Stay indoors or in a shaded area.
- If you are taking any medications or skin products that are known to cause photosensitivity, stop or change their use as directed by your doctor.
- Use sun protection. Wide-brimmed hats, long-sleeved clothing, pants, and window films can help.
- Use a sunscreen with at least SPF 30. Reapply every two hours, and even more if you're sweating or swimming.
Remember, sunscreen does not provide 100% protection. Therefore, sunscreen should be used in conjunction with other protective measures.
How do you relieve a sun allergy?
If you suddenly experience symptoms of an allergy after going out in the sun, don't panic and do these things:
- Get out of the sun as soon as possible. Come home, or go to a place with good shade.
- Apply a cold, damp cloth to the affected area. This will reduce the inflammation and itching a little.
- Drink plenty of water. It is important to maintain good hydration levels in the body.
- Take an over-the-counter antihistamine pill. This will help control the itching and rash quickly.
When should I see a doctor as soon as possible?
If you have a sun allergy and experience any of these severe systemic symptoms , it is essential to seek medical advice immediately :
- Chest pain
- Fainting
- Muscle cramps
- Severe headache
- Stomach pain
- Sudden and severe weakness
- Trouble breathing or swallowing
- Vomiting
Symptoms like these indicate that the condition may be a bit more serious. So, see a doctor without delay.
Final Take-Home Message
