Allergy is a fairly common disease, the exact cause of which is sometimes impossible to determine. This also applies to solar urticaria - an allergy to sunlight.
It manifests itself in the form of itching and redness on the skin, and sometimes can even result in attacks of suffocation.
Typically, symptoms occur after just a few minutes in the sun. They can last as little as a few minutes or as long as several hours.
As we have already said earlier, no one has been able to establish the causes of solar urticaria.
Like other types of allergies, the reaction occurs due to the release of histamine (or its analogue) in skin cells, but what provokes it is not clear.
How to treat solar urticaria? In cases where it does not go away on its own, your doctor may prescribe antihistamines (for mild cases) or a thorough examination and medication (if the reaction is severe).
Phototherapy is sometimes prescribed as a treatment – treating the skin with ultraviolet radiation from a special lamp. Phototherapy reduces sensitivity to the sun.
Such people are also advised to walk more in the spring to avoid severe reactions in the summer.
However, people who suffer from sun allergies usually walk early in the morning before 10 am and in the evening after 4 pm, always use sunscreen, sometimes take an umbrella and rarely allow themselves to wear shorts and T-shirts.
