How can sunlight trigger lupus?

ANSWER

Ultraviolet (UV) light from the sun damages your cells. That's why you get sunburned. But in some people, the immune system attacks the sunburned, or damaged, cells.

UV light not only seems to trigger lupus, it also appears to make symptoms worse. When people with lupus are exposed to UV rays, they tend to get joint pain and feel fatigued.
