Sun allergies are very rare, but there are some people who are prone to a rash after exposure to sunlight. You can suffer from various types of allergies, but polymorphic light eruption (PMLE) is the most common. It is an autoimmune condition that erupts after sunlight exposure.

This kind of rash can be itchy and burning that may show up on your skin within hours or within a period of two to three days after exposure to sunlight. It may last for up to two weeks. The rash appears on parts exposed to sunlight, and this does not just include the face. Neck, chest, and arms are also vulnerable.

You can have prickly heat even in areas like body folds and full back when you do not expose it to the sunlight.
When your body gets symptoms?
It depends on your body. It can appear rarely, or it may show up every time you expose to the sunlight. It may take 20 minutes to emerge. When you are sunbathing, you are more likely prone to this rash.
However, you can get it even if you are sitting in thin clothing near a window. Some people have a very sensitive immune system; sunlight absorbed through thin clothing can affect that area.
Studies have reported that most of the people get PLME after several hours. However, if you try to avoid the sun, the rash will settle down and disappear without leaving a scar within a couple of weeks. It is not necessary that it will return when you are exposed to sunlight.

Tips for preventing the sun rash
Many conditions are out there that have no cure at all, and PLME is one of them. However, you can prevent yourself from suffering from a dry, itchy patch by taking certain kinds of medication and following preventive measures.
1. Avoid the sun
Avoiding exposing yourself to sunlight can prevent you from getting this sort of rash. Try to avoid it at peak hours between 11 am and 4 pm. In these hours, harmful sun rays are at their strongest, and if your skin is extremely sensitive, you are highly prone to PLME.
If you cannot avoid being outdoors at this time, you should wear protective clothing. If you fully cover your body, you can easily prevent yourself from this rash.
2. Use sunscreen lotion
A lot of sunscreen lotions are on the shelves, and you get confused about which one you should use. The fundamental formula of making a sunscreen lotion can never change regardless of the company’s tag it has got.
All sunscreen lotions are the same, and they work in the same way. Do not focus on advertisements that involve outlandish claims to stand out. SPF matters because it is a substance that decides how strongly it can prevent your skin from its rays.
Choose SPF 30 or above. Make sure you apply it on your exposed skin, such as your face, neck and arms, at least 15 minutes before going outside. It is imperative to understand the correct quantity of sunscreen you should use at a time.
Most people do not apply sufficient sunscreen. An adult needs two teaspoons of sunscreen to apply on the face, neck and arms. If you are sunbathing, you need up to two tablespoons of sunscreen to pour over your body.
Sunscreen is not like a solid shield that acts like shade to prevent you from the damage of the sunlight. Regardless of your SPF amount, you cannot spend the whole day outdoors with just a one-time application. You should apply it every two hours. However, the frequency of applying sunscreen increases when you are standing or long time under the sun.
3. Use steroid creams and ointment
Consult your GP if you think you need medical assistance. Most people think it will go away automatically and do not consult a doctor as their fees are expensive. Well, you cannot pay for the consultation fees and medicines. Take out payday loans for the unemployed.

Your doctor may ask you to harden or toughen your skin as it increases the resistance of your skin to UV rays. This process involves going out for a short period in the spring season. You will build the resistance over time.
Do not expose yourself to the sunlight for a long time just because you are to build the UV resistance quickly. Building resistance does not mean that you will not get PLME ever in your life. It means your skin will not be as much sensitive as it is now.
You can clearly understand how long you should stay under the sun to prevent it down the line. Note the effects of hardening are lost in the winter. You will have to put in the effort to build up resistance in the spring season every year.
