If you have a sun allergy or an increased sensitivity to the sun, you can help prevent a reaction by taking these steps:
- Limit your time in the sun. Stay out of the sun between 10 a.m. and 4 p.m. when the sun is brightest.
- Avoid sudden exposure to lots of sunlight. Many people have sun allergy symptoms when they are exposed to more sunlight in the spring or summer. Gradually increase the amount of time you spend outdoors so that your skin cells have time to adapt to sunlight.
- Wear sunglasses and protective clothing. Long-sleeved shirts and wide-brimmed hats can help protect your skin from sun exposure. Avoid fabrics that are thin or have a loose weave — UV rays can pass through them.
- Apply sunscreen frequently. Use broad-spectrum sunscreen with a sun protection factor (SPF) of 30 or higher on exposed skin. Reapply sunscreen every two hours.
