Frequently Asked Questions

Lupusis anautoimmune diseasein which your body mistakenly attacks your joints, muscles, and skin. These attacks can show up as joint swelling or muscle soreness for some people with this chronic disease. Butterfly-shaped skin rashes, mottling (red or purple marbled skin), and sensitivity to the sun are also common lupus symptoms.

About 5 million people worldwide, and 1.5 million in the United States alone, have been diagnosed with lupus. The disease is most common in early to mid-adulthood, and 90% of cases develop in women.

Find out why people with lupus may be more sensitive to sun exposure and what you can do to protect your skin.

UV Radiation Risks

Does Sun Exposure Help Eczema?

Lupus can increase photosensitivity (immune system reaction to the sun’s rays), a symptom that affects between 40% and 70% of people who have lupus.UV radiation damages cells and alters DNA. The damage can be more severe in people with lupus because their cells are more sensitive to light and damaged cells are removed from the body more slowly, which can cause an attack on theimmune system.

Symptoms

UV light and some artificial light can trigger reactions in people with lupus. These reactions can happen immediately or develop weeks later and include:

Rashes or skin lesions that appear after sun exposure can come and go within hours or days of exposure, or they can last for months.UV light can also cause a lupus flare (or flare-up), which is a body-wide worsening of lupus symptoms, including fatigue, joint pain, tingling, and numbness.

How Much Sun Exposure Is Too Much?

Protecting your skin from UV radiation is recommended for everyone, but it’s even more important for people withphotosensitivityfrom lupus. Below are some strategies to protect your skin from the sun and other forms of UV light.

Wear Sunscreen

Apply sunscreen to your skin to provide a chemical or physical barrier to UV radiation.Most commercial sunscreens offer a combination of these two types of protection, as follows:

Proper sunscreen application is crucial, regardless of which type you choose. Most people need to apply a palmful of sunscreen every two hours or more often if they are getting wet or sweaty.

Choosing SunscreenSunscreens that offer broad-spectrum protection against both ultraviolet A (UVA) and ultraviolet B (UVB) rays and have a sun protection factor (SPF) of at least 30 are recommended. Sunscreen can expire, so be sure to check your sunscreen expiration dates from year to year.

Wear Protective Clothing

Most clothing offers protection against UV radiation. You can purchase clothing or hats with UV-blocking properties or products to wash your clothes in to increase their level of UV protection.Sunglasses are also important protective gear, as UV radiation can cause eye damage and other problems.

Stay in the Shade

Avoiding sunlight or other sources of strong UV radiation will help protect your skin. The sun is strongest in the summer between 10 a.m. and 4 p.m. in most locations. During these hours, finding shade may be your best choice. Remember that UV rays can pass through windows and that you are exposed to UV radiation on cloudy days.

When to See a Healthcare Provider

Lupus treatmentvaries from one person to the next and changes over time. If you have lupus, schedule regular appointments with your healthcare provider to review treatment and symptoms, especially after sun exposure. Some cases of photosensitivity in lupus are mild, while others can require more intense treatments to avoid a larger flare-up.

Summary

Exposure to UV radiation from natural and artificial light can be damaging to everyone, but minimal exposures can cause a flare-up if you have chronic lupus. This autoimmune condition can trigger larger attacks, so knowing your triggers and avoiding exposure is important if you have lupus with photosensitivity.
