Women who live in areas with higher levels of outdoor light at night may be at higher risk for breast cancer, according to a study from Harvard T.H. Chan School of Public Health. The link was stronger among women who worked night shifts.
哈佛大学陈曾熙公共卫生学院的一项研究表示,那些在夜晚户外光线较强地区生活的女性更容易患上乳腺癌。对于那些上夜班的女性来说,这之间有着更紧密的联系。
Previous studies have suggested that exposure to light at night may lead to decreased levels of the hormone melatonin , which can disrupt circadian rhythms—our internal “clocks” that govern sleepiness and alertness—and, in turn, lead to increased breast cancer risk.
先前的研究指出,晚上暴露于光线中可能会降低褪黑激素的含量,扰乱生理节奏,也就是我们身体内部控制睡意和敏捷性的“生物钟”,继而增加罹患乳腺癌的风险。
The new study, the most comprehensive to date to examine possible links between outdoor light at night and breast cancer, looked at data from nearly 110,000 women enrolled in the Nurses’ Health study II from 1989-2013. The researchers linked data from satellite images of Earth taken at nighttime to residential addresses for each study participant, and also considered the influence of night shift work. The study also factored in detailed information on a variety of health and socioeconomic factors among participants.
