Bumps on skin after sun exposure are a symptom of sun allergy. This article will explain the different types of sun allergies, their symptoms, and the treatment for these allergies.
Spots on skin after it has been exposed to sun are not something one should worry about too much. However, one needs to prevent further sun exposure, and take proper care of the itchy skin bumps after sun exposure with an appropriate remedy.
Sun Allergies and Symptoms
Sometimes, when the skin is exposed to the sun, one gets a sun allergy (photosensitivity), which is a reaction of the immune system to the sunlight. Following are the most common types of sun allergies:
One gets large itchy red bumps in solar urticaria. This is a rare form of hives, which happens when exposed to ultraviolet light.
One gets this allergy on the skin part where sunscreens or other products have been used. After sun exposure, one develops a skin rash, chills, headache, and nausea.
Polymorphous Light Eruption (PMLE)
In this allergy, one experiences white itchy bumps on skin after exposure to sun. There is also redness, burning, blistering, and swelling in PMLE. A person might also experience nausea, chills, and headache.
Actinic Prurigo (hereditary PMLE)
One develops itchy bumps on the skin surface in actinic prurigo. After severe scratching, the skin becomes crusty and scaly, and looks similar to the skin disorder, eczema.
There are many natural home remedies which one can use to treat a sun allergy. Allopathic treatments using creams are also very effective and provide good relief from itching and redness of the skin.
Natural remedies are recommended for people who are affected by long term allergic reaction to the sun. Cut an aloe vera leaf lengthwise and apply the gel inside the leaf on the affected area. This will immediately help soothe the skin. You can also dab some fresh milk to the affected area. Soaking in an oatmeal bath for itchy skin is another treatment of sun allergy. It reduces itching and rehydrates the skin.
For a mild rash, apply ice compresses to the affected skin. You can also take an antihistamine for allergy relief. There are many anti-itch creams available over the counter. Choose a cream which has corticosteroid (betamethasone 0.1% concentration) or a cream containing zinc oxide.
Follow the important precautions given below to avoid sun allergies and to prevent further aggravation of the affected skin.
- When going out in the sun, wear full-sleeved clothes and pants, a wide-brimmed hat, and sunglasses. Women can tie a big scarf around the head to protect the head and neck.
- Keep drinking lots of water when out in the sun to keep yourself well hydrated.
- Use a generous amount of sunscreen on the skin, which is exposed to the sun. Apply a sunscreen which is water-resistant and has a minimum SPF 30.
- Eat healthy food containing vitamin D, instead of exposing yourself to the sun for this vitamin.
- Always avoid tanning beds as UV light from these beds can cause wrinkles on the skin, and can lead to skin cancer.
- Cover children in full protective clothing and apply sunscreen on their skin to protect it from exposure to the sun.
If you take the aforementioned precautions, you will eliminate any sun allergy to a great extent and avoid the nasty itchy bumps. However, if you notice a mole which looks different from the other bumps or spots on the skin, this could be a sign of skin cancer. In such a case, it is important to consult a dermatologist since a skin cancer can be treated easily if detected in its early stages.
