If you’re among the vast majority of psoriasis sufferers, you’ve probably found that your psoriasis symptoms improve in the spring and summer.
Doctors believe the improvement comes from increased exposure of your skin to the sun’s ultra-violet light, which suppresses the rapidly multiplying skin cells that are the hallmark of psoriasis. An increase in the amount of moisture in the air may also provide some relief, because dry skin can make psoriasis symptoms worse.
But some people find that warmer weather actually triggers psoriasis flares. And it can be hard to enjoy fun in the sun when you’re worried about how people will respond to the appearance of your psoriasis.
Here are answers to seven frequently asked questions about psoriasis in summer and spring.
1. How can I safely use sunlight as a psoriasis treatment?“You certainly want to avoid burning if you’re going to use sun therapy,” says Mark Lebwohl, MD, professor and chairman of dermatology at Mount Sinai School of Medicine of New York University. “The idea is to get gradually increasing doses of sun without burning.”
Building your exposure to the sun over time, increasing by around five minutes a day, will help you safely reach a psoriasis-easing dose of sunlight. Remember that the sun’s ultraviolet rays can harm your skin, though, and make sure you aren’t out in the sun for more than 30 minutes without applying sunscreen to minimize excessive sun damage. This will also help prevent sunburn, which can cause flares in some psoriasis sufferers.
Even when using sunlight as a psoriasis home remedy, you can take precautions to protect areas of skin without lesions.
“What I recommend for everyone is to put sunscreen on unaffected skin so that only plaques are exposed to the sunlight," says Melissa Magliocco, MD, acting chief of the Division of Clinical Pharmacology at the University of Medicine and Dentistry of New Jersey-Robert Wood Johnson Medical School.
Be aware that some psoriasis treatments make your skin more sensitive to the sun, so always discuss sun therapy with your doctor before you begin.
2. How will swimming in pools or the ocean affect my psoriasis?The ocean’s saltwater has been touted for centuries as a remedy for many medical conditions, and its purported benefits extend to psoriasis treatment. The combination of salt and water may help slough off dead skin, leading to a reduction in psoriasis symptoms. At the same time, your time in the water will provide beneficial exposure to the sun.
If you’re headed for the pool, keep in mind that prolonged periods of time in heated water could make your psoriasis more uncomfortable. To reduce the likelihood that chlorine will strip your skin of its natural moisture and make your dry, flaky skin worse, rinse off in fresh water as soon as you can after swimming and rehydrate your skin with a gentle moisturizer.
