Answer

Sunlight or phototherapy may be beneficial, particularly in chronic cases. Ultraviolet radiation helps reduce the inflammatory activity within the skin. The risk of heat worsening the pruritus and of ultraviolet light inducing cutaneus malignancies must be weighed against the potential benefits.
