The abnormal skin response that occurs on exposure to sunlight is known as photodermatitis. It could be either acute or chronic in nature and display characteristics like skin rashes, scaly patches of skin as well as blisters. The other symptoms of the condition can be nausea, fever, headache and so on. The abnormal response that occurs is a result of the adverse reaction of the body's immune system to ultraviolet rays of the sun. Regarding the causes that can make you respond adversely to UV rays, they can be use of certain medications, inherited photosensitivity and exposure to certain weeds and edible plants.
HOW IS PHOTODERMATITIS DIAGNOSED?
Exposure to UV rays for about 30 minutes to a few hours as well as exposure during the hours of 11 am and 2 pm can increase one's risk for photodermatitis.
