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.
黑色素瘤確定的危險因子之一是紫外線，所以暴露於日光或日光浴牀很可能都是危險因素。
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.
和朝陽一道醒來、沐浴在清晨的陽光下，這不僅能改善你的生活方式，還能幫助一些人減輕失眠的痛苦。
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.
陽光中的紫外線還會對皮膚的免疫系統造成壓力，這可能就是爲什麽，許多兒時的太陽暴曬會造成小兒黑色素皮膚癌。
