Working late hurts mental ability

A study of British civil servants suggests working long hours causes a decline in cognitive ability during middle age.

The report, published in the American Journal of Epidemiology, found study participants who worked more than 55 hours per week had lower scores in vocabulary and cognitive reasoning than participants who worked no more than 40 hours per week.

More than one in four workers surveyed by the Chartered Institute for Personnel and Development reported that working long hours had a negative impact on their health, Health Insurance & Protection magazine reported Wednesday.
