What should a patient with SLE do to minimize symptom exacerbation related to sun exposure?

Using sunscreen with an SPF of at least 15 is the recommended action for patients with systemic lupus erythematosus (SLE) to minimize symptom exacerbation related to sun exposure. People with SLE are particularly sensitive to ultraviolet (UV) light, which can trigger or worsen symptoms such as skin rashes, fatigue, and other systemic manifestations of the disease.

By applying a broad-spectrum sunscreen, patients can help protect their skin from the harmful effects of UV radiation. An SPF of at least 15 is suggested because it provides a barrier against UVB rays, which are primarily responsible for sunburn and can exacerbate lupus symptoms. The use of sunscreen should be part of a comprehensive sun protection strategy that may also include wearing protective clothing and seeking shade during peak sunlight hours.

Staying indoors all day can restrict normal activities and is not a practical or sustainable approach for many individuals. Heavy makeup may offer some level of protection, but it does not provide the necessary sunblock effect, and avoiding hydration is counterproductive, as staying hydrated is essential for overall health and can help manage certain symptoms of SLE. Therefore, the best practice is to use sunscreen to safeguard against the adverse effects of sun exposure.
