sun light exposure

基本解释

One of the established risk factors for melanoma is UV light, so both exposure to sun and exposure to tanning beds are probably risk factors.
黑色素瘤确定的危险因子之一是紫外线，所以暴露于日光或日光浴床很可能都是危险因素。
Waking up to the sun and getting early-morning exposure to its light not only affects our behaviour but also can help those suffering from insomnia.
和朝阳一道醒来、沐浴在清晨的阳光下，这不仅能改善你的生活方式，还能帮助一些人减轻失眠的痛苦。
The ultraviolet light in sunlight also suppresses the skin's immune system, which may be why lots of early-life sun exposure is associated with earlier melanoma skin cancers.
阳光中的紫外线还会对皮肤的免疫系统造成压力，这可能就是为什么，许多儿时的太阳暴晒会造成小儿黑色素皮肤癌。
