10. Photosensitivity: Individuals with SLE may Develop Worsened Symptoms after Exposure to Sunlight
Photosensitivity is a common symptom of systemic lupus erythematosus (SLE), affecting approximately 30-60% of people with the condition. It refers to the development of skin rashes or the worsening of existing symptoms following exposure to ultraviolet (UV) light, typically from sunlight.
In some cases, exposure to artificial light sources, such as fluorescent lights, can also trigger photosensitivity. This heightened sensitivity to UV light can lead to discomfort and skin damage, making it an important symptom to manage for individuals with SLE.
The exact mechanism behind photosensitivity in SLE is not fully understood, but it is thought to involve an immune response to UV-induced cell damage. When the skin is exposed to UV light, it can cause cellular damage and trigger an inflammatory response.
In people with SLE, this response is exaggerated, leading to the development of rashes and other skin manifestations. These can range from mild, such as redness or itchiness, to more severe, such as the development of discoid lupus lesions, which are thick, scaly, and potentially disfiguring.
Photosensitivity can significantly impact the daily lives of individuals with SLE, as they may need to limit their exposure to sunlight or artificial light sources to prevent flare-ups. This can lead to challenges in participating in outdoor activities, maintaining social relationships, and managing work or school commitments. Moreover, the visible skin manifestations of photosensitivity can affect a person’s self-esteem and body image, potentially leading to feelings of embarrassment or depression.
There are several strategies to help manage photosensitivity in individuals with SLE. It is essential to protect the skin from UV exposure by wearing sun-protective clothing, using broad-spectrum sunscreen with a high SPF, and seeking shade when outdoors.
Additionally, wearing sunglasses that block both UVA and UVB rays can protect the eyes and the sensitive skin around them. Some people may also benefit from using UV-protective window films on car windows and home windows. It is crucial to discuss photosensitivity symptoms and concerns with a healthcare provider, as they may recommend adjustments to medications or other treatments to help manage this aspect of the condition.
