阿不思與他的快樂伙伴

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 didrecover, 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.
