When an individual has a sun allergy, what they really have is a negative reaction to sunlight in their immune system. Usually this can happen when someone has been exposed to the sun too much and the body’s immune system will treat the sun as a disease or a foreign object and will turn to trying to fight the skin. Most generally this can result in rashes or blisters, and they can be very irritating.
The most commonly affected areas of the body that experience rashes are the back of the neck, the back of the hands, the forearms and the lower legs. However, a sun allergy only affects a small group of people.
Most individuals will never have to deal with the effects of blisters and such, but for those that do, it is uncertain how these allergies are even caused in the first place. Many scientists have studied this question and do not have a concrete answer, but they have suggested that there could be a strong link between the allergy and it being passed from parents. If it is truly inherited, it’s important to understand what a sun allergy is and teach your children about it as well.
There have been multiple symptoms reported as a result of having a sun allergy, and some of the most common have been an itchiness and a rash within a couple of hours to sunlight exposure, headaches, chills and even nausea. Another strong indication can be seen if the individual has these breakouts occur on the face itself. Sometimes the skin that is covered by clothing can have the rash and breakouts spread to that area as well. One of the strongest indications is hives and a rash appearing within minutes of the exposed area, however, and it is the number one symptom to watch out for.
Overall it is extremely important to understand exactly what is going on with your body and skin and make sure that you get properly diagnosed for whether you have a sun allergy or not. You need to speak with your medical professional to find out the best course of action, and to make sure that you can control your possible disease.
