Most SLE patients are sensitive to sun & other forms of UV
Exposure to the sun can trigger a rash, & can
also result in fever, fatigue, joint pain, & other lupus symptoms.
Both UVA & UVB rays are problematic, & lupus
patients are advised to wear sunscreen whenever outdoors, even in
cloudy weather (UV rays can penetrate clouds).
Many are also sensitive to light emitted from fluorescent
bulbs(UVB) & halogen lamps(UVA).
