Shift work ages the brain 夜班工作加速大脑老化

科学家们警告说，长年上夜班可能对人的大脑有害。刊登在《职业与环境医学》期刊上的这项研究发现一个连续上了十年夜班的人大脑老化加速了六年多。以下是 BBC 记者 James Gallagher 发来的报道：

The damaging effects of shift work on the body are well known. This study shows the impact on the mind as well.

Three thousand people performed tests of memory and speed of thought. Those with more than ten years of shift work under their belts had the same results as those who didn't do shifts but were six-and-a-half years older.

The good news is that when people in the study stopped shift work their brains did recover, although it took five years.

The researchers said shift work was a necessary evil in modern society, but more needed to be done to improve the health of those toiling through the night.
