Shift work could be affecting employees' mental ability, scientists claim

Working an irregular shift pattern may be causing long-term damage to people’s mental abilities and memory, according to new research.

The study, carried out by researchers from the universities of Toulouse and Swansea, surveyed 3000 people living in France.

Researchers revealed that the amount of cognitive decline seen in people who worked irregular shifts for a decade was equal to six and a half years’ worth of natural, age-related cognitive deterioration.
