Sunlight's effect on Lupus
One of the well-known features of lupus is sensitivity to sunlight. Henrietta Aladjem, who has contributed so much education about lupus, called her book "The Sun is my Enemy".
There is no doubt that sunlight (more specifically UV light) has a major effect in activating the disease. Many patients notice that their rashes, as well as joint pains and other symptoms are worse after a period of sunbathing. Nevertheless, sun sensitivity is not a universal problem. Sun barrier creams have only been of limited help. Various local lupus groups have collected information from manufacturers in their own countries and have provided considerable guidance in choice of makeup and UV-barrier creams.
