Sun exposure is a major trigger for lupus symptoms. About half of people with lupus experience photosensitivity, which means they're sensitive to UV rays from both sunlight and artificial light sources. When UV rays damage skin cells, people with lupus have trouble clearing these dead cells, which triggers an immune response leading to inflammation and rashes.
Even brief sun exposure can cause flare-ups that feel like severe sunburns, with symptoms including extreme heat, redness, and burning sensations on the skin. Beyond skin issues, sun exposure can trigger broader lupus symptoms like joint pain, fatigue, lightheadedness, and flu-like symptoms. To protect yourself, it's essential to wear broad-spectrum sunscreen with a high SPF that blocks both UVA and UVB rays. Additional protection should include wearing protective clothing like long sleeves, wide-brimmed hats, and sunglasses. Using an umbrella for shade can provide extra defense against UV rays.
Some medications, particularly NSAIDs used to treat lupus symptoms, can increase photosensitivity. Always discuss with your doctor how your medications might affect your sun sensitivity and develop a plan to manage sun exposure safely.
