How does sunlight treat psoriasis?

ANSWER

Scientists aren't sure how it helps, but many people say their symptoms improve when they get a little sun on a regular basis.

That said, don't overdo it. Sunburns can make patches worse. Ask your doctor how much time you should spend catching rays. When you go out, slather sunscreen on areas that don't have psoriasis on them. Make sure the screen is SPF 30 or higher and protects against both UVA and UVB rays. Those with zinc oxide or titanium dioxide are less likely to bother your skin.
