Research: Working irregular shifts ages the brain

Working shifts for over a decade can accelerate brain aging by 6.5 years, exacerbating health risks.

The research conducted by Université de Toulouse and Swansea University underscores the profound impact of working shifts on cognitive abilities and memory.

Their findings suggest that enduring such schedules for a decade or more can accelerate brain aging by an additional 6.5 years, adding to the mounting evidence linking non-traditional work hours to various health risks. These risks include cancers, heart attacks, strokes, ulcers, and metabolic diseases like diabetes.

The study, involving 3,000


in south-west France, revealed that those with irregular work hours exhibited significantly lower memory, processing speed, and overall cognitive function compared to those on standard schedules.


Furthermore, individuals enduring over a decade of rotating shifts experienced even more pronounced declines in mental function, equivalent to enduring an extra 6.5 years of age-related cognitive decline compared to their counterparts with regular schedules.


These findings underscore the critical need for further research and policies aimed at mitigating the adverse effects of non-traditional work schedules on health and cognitive function.
