How does the sun affect Lupus?

Lupus is an autoimmune disease that can affect many parts of the body, including the skin, joints, kidneys, and lungs. Ultraviolet (UV) radiation from the sun can worsen lupus symptoms, including skin rashes, joint pain, and fatigue.

How does UV radiation trigger lupus flares?

UV radiation can damage the skin, leading to the release of inflammatory chemicals that can trigger lupus flares. In addition, UV radiation can activate the immune system, which can also lead to flares.

What are the symptoms of a lupus flare triggered by UV radiation?

The symptoms of a lupus flare triggered by UV radiation can include:

* Skin rashes

* Joint pain

* Fatigue

* Fever

* Headache

* Nausea

* Vomiting

How can I protect myself from UV radiation?

You can protect yourself from UV radiation by taking the following steps:

* Avoid spending long periods outdoors in the sun.

* Wear protective clothing, such as long sleeves, pants, and a hat.

* Apply sunscreen with an SPF of 30 or higher to all exposed skin.

* Reapply sunscreen every 2 hours, or more often if you are swimming or sweating.

* Seek shade during the peak hours of sunlight, between 10 am and 4 pm.

If you have lupus, it is important to talk to your doctor about how to protect yourself from UV radiation.
