Which condition is an indication for UV light therapy?

• A. Psoriasis
• B. Migraine
• C. Bronchitis
• D. Osteoporosis

Answer: (A)

UV phototherapy treats skin conditions where slowing skin cell growth and calming inflammation helps. Psoriasis features rapid keratinocyte proliferation and inflammatory plaques, so exposing the skin to controlled UV light can reduce plaque formation, soften scales, and lessen itching by dampening the immune signals driving the disease. That makes psoriasis a true indication for this therapy. The other options aren’t treated with UV phototherapy—migraine is a neurologic condition managed with medications and lifestyle strategies, while bronchitis and osteoporosis involve systemic issues that aren’t addressed by skin-directed light therapy. When used, phototherapy is done under supervision due to risks like sunburn, photoaging, and potential long-term effects, with eye protection and, in some cases, photosensitizing agents.
