Increase Cancer Risk
提高患癌几率
A small (but growing) body of research suggests that short and poor sleep can up risk for certain types of cancer. A 2010 study found that among 1,240 people screened for colorectal cancer, the 338 who were diagnosed were more likely to average fewer than six hours of sleep a night.
目前已有少量的研究机构提出假设，即睡得少、睡眠质量低都会提高罹患某种癌症的几率；有关这方面的研究正在日益壮大。一项2010年的研究表示，在1240位接受结直肠癌检查的人群中，338位确诊患癌的人士的平均睡眠时间少于6小时。
Even after controlling for more traditional risk factors, polyps were more common in people who slept less, according to the study.
即使是在排除了一些常见危险因素以后，得出的结论依然是：睡得较少的人，罹患结直肠息肉的几率更高。
Getting just six hours of sleep a night has also been linked to an increase of recurrence in breast cancer patients. The study's author has pointed to more and better sleep as a possible pathway of reducing risk and recurrence.
每天只睡6小时同时也易导致乳腺癌复发。该研究项目的负责人认为，高质量的足够睡眠是一种可能有助于降低患癌几率和复发几率的方式。
