Psoriasis causes red, scaly patches to appear on the skin. It can look like a rash, so you may worry that you could get it from someone else or pass it to others. But rest easy: It's not contagious. You cannot catch the disease by touching someone who has it.
But that doesn't mean you can forget all about psoriasis care when summer arrives. Follow these five tips to manage your condition in the summer:
No. 1: Soak Up the Sun -- Responsibly
Most people with psoriasis find that it gets better in sunlight.
"About 15 to 20 minutes a day of unprotected sun exposure can be helpful for psoriasis flares," Boh says.
But sunbathing doesn't work for everyone. And even if it does work for you, be careful not to overdo it. Besides raising your risk of skin cancer, you can make your psoriasis worse if you get a sunburn.
"Any minor skin trauma, including sunburn, can cause Koebner phenomenon -- psoriasis plaques that form at the site of the skin injury," says Kristina Callis Duffin, MD. She's an assistant professor in the department of dermatology at the University of Utah.
"So proceed with caution when you're getting sun," Callis Duffin says. "Psoriasis medications, as well as some other drugs like antibiotics, can also make you more sensitive to the sun in general."
No. 2: Be Water-Wise
Swimming can be a mixed blessing for people with psoriasis. Many say that a soak in a pool or hot tub can soften and help you shed patches of hard, flaking skin. On the other hand, chlorine can further dry out your skin.
"I recommend that my patients rinse off in the shower and use moisturizer immediately after getting out of a chlorinated pool or hot tub," Boh says. "The saltwater in ocean swimming often provides relief from psoriasis, but if you have a bad flare with areas that are open, there's also a risk of infection."
No. 3: Keep Bug Bites Away
Insect bites can also trigger Koebner phenomenon, so protect yourself from mosquitoes and other bugs with a heavy layer of insect repellent.
"If you get bitten, apply a topical corticosteroid right away so that it doesn't get worse," Boh says.
