A 19-year-old male asked:

Does being exposed to the sun a lot cause psoriasis to flare up? and does having psoriasis increase my likelihood of having arthritis?

No and maybe: In fact uv light can be an effective treatment for psoriasis and can reduce flares. However, uv light also increases the risk of skin cancer, so exposure must be limited and careful. Psoriasis patients can develop psoriatic arthritis; the risk is particularly increased if there is extensive skin involvement, or involvement of the scalp or nails.

Psoriasis: Psoriasis is a common, chronic skin condition that causes red patches on the body. About 1 in 20 people with psoriasis will develop arthritis with the skin condition. In most cases, psoriasis comes before the arthritis. New medications that block an inflammatory protein called tumor necrosis factor (tnf) are the treatment of choice: humira, enbrel, remicade, simponi.

Ultraviolet light can help psoriasis, but may flare up if the sun exposure causes a sunburn. Consult a dermatologist for management.
