Sign 10. Sun Sensitivity: Lupus’s Unusual Reaction to Light
Sun sensitivity, or photosensitivity, is a peculiar early sign of lupus affecting about 40-70% of people with the condition. It manifests as an unusual reaction to sunlight, leading to a rash or flare-up after exposure. People with lupus may find that their skin breaks out in rashes or sores after spending time in the sun or under fluorescent lights.
Photosensitivity in lupus is thought to be due to abnormalities in the immune response, where ultraviolet (UV) light triggers inflammation in the skin. This response can lead to red, scaly patches or a rash that looks like sunburn. Besides the skin, UV light exposure can also cause systemic symptoms in lupus, such as fatigue, joint pain, and fever.
To manage photosensitivity, it’s crucial to avoid excessive sun exposure, especially during peak UV times. Your healthcare provider may recommend broad-spectrum sunscreen with a high SPF, protective clothing, and sunglasses to protect your skin and eyes. When indoors, using UV-protective films on windows and fluorescent light covers can help reduce exposure. (10)
