It is well known that ultraviolet radiation can exacerbate skin disease in patients with lupus erythematosus. While many patients are advised to avoid sunlight and artificial tanning, it is not clear how best to counsel patients regarding the use of indoor lamps. Indeed, many of the light bulbs commonly used in the home and workplace emit low-dose ultraviolet radiation. The irradiance is considerably lower than that of the sun, however the exposure time can last for hours and is typically repeated on a daily basis. Therefore, it is possible that this chronic exposure could ultimately result in a significant accumulation of damage.
众所周知,紫外线辐射会加重红斑狼疮患者的皮肤病。虽然许多患者被建议避免阳光直射和人工晒黑,但对于如何就使用室内灯具向患者提供最佳建议尚不清楚。事实上,家庭和工作场所常用的许多灯泡都会发出低剂量的紫外线辐射。其辐照度远低于阳光,但暴露时间可能持续数小时,且通常每天重复。因此,这种长期暴露最终有可能导致大量损伤积累。
