Solar urticaria is a rare type of allergy that people can develop to certain wavelengths of light, particularly sunlight. The condition can affect anyone, but usually is seen in people aged ten and older. Solar uticaria is normally a persistent, chronic condition in which hives appear on sun-exposed skin after less than 30 minutes or so of direct sun exposure. Very rarely, a person may also experience additional symptoms, such as headache, nausea, fainting or swelling of tongue or lips. Once sun exposure is removed, the rash disappears within a few hours.
