上夜班不光会让你长痘,新研究发现,上夜班的人身体会停止自动修复日常的DNA损伤,从而可能导致基因突变和癌症。
Night shift work may stop the body repairing daily damage to DNA and raise the risk of mutations which lead to cancer, a new study suggests.
一项新研究显示,上夜班会阻止身体修复日常的DNA损伤,令基因突变风险增大进而引发癌症。
The link between working at night and poor health has been known for several years, with those who work after dark more likely to suffer diabetes, obesity, poor fertility, heart attacks and tumors.
人们多年前就已经知道上夜班和健康不良之间的联系。那些上夜班的人更容易患上糖尿病、肥胖、生育困难、心脏病和肿瘤。
Scientists believed that disruption to the body’s natural body clock was responsible for the increased risk of chronic illness, but could never pinpoint the mechanism.
科学家认为,扰乱人体自然的生物钟会增加慢性病的风险,但却无法确定其原理。
Now US researchers have discovered that when people work nights they produce 80 percent less of a chemical which is a by-product of DNA tissue repair. They say it indicates that the body is not carrying out the crucial restoration to cells which should happen naturally overnight.
如今美国研究人员发现,人们上夜班时,体内分泌的一种化学物质将减少80%,这种化学物质是修复DNA组织的副产品。研究人员称,这表明人体没有对受损的细胞进行关键的修复,这种修复本应在夜间自然地完成。
