Indoor tanning has become increasingly popular over the past decades, despite evidence of an increased risk of melanoma and, possibly, nonmelanoma skin cancer. Tanning bed proponents cite the health benefits of vitamin D to support indoor tanning, including concerns that reduced vitamin D levels or certain vitamin D receptor polymorphisms may be associated with increased incidence of various cancers, including cutaneous melanoma. However, most tanning devices primarily emit ultraviolet A, which is relatively ineffective in stimulating vitamin D synthesis. Health benefits can be fully dissociated from the ultraviolet exposure risks with vitamin D supplementation, although optimal levels remain to be established. Indoor tanning represents an avoidable risk factor for skin cancer, and education of the general public as well as the enactment and stricter enforcement of indoor tanning legislation are a public health imperative.
在过去几十年中，尽管有证据表明患黑素瘤和非黑素瘤皮肤癌的风险增加，但室内晒黑已变得越来越流行。晒黑床的支持者引用了维生素 D 的健康益处来支持室内晒黑，包括担心维生素 D 水平降低或某些维生素 D 受体多态性可能与各种癌症（包括皮肤黑素瘤）的发病率增加有关。然而，大多数晒黑设备主要发射紫外线 A，其在刺激维生素 D 合成方面的效果相对较差。通过维生素 D 补充，可以将健康益处与紫外线照射风险完全分离，尽管仍需确定最佳水平。室内晒黑是皮肤癌的可避免危险因素，因此对公众进行教育以及制定和更严格地执行室内晒黑立法是公共卫生的当务之急。
