Working long hours damages the brain

The stress and exhaustion of working overtime can harm the brain's ability to process information, a study suggests. Middle-aged workers putting in 55 hours or more a week had poorer brain function than those who clocked up 40 hours.

Their scores were lower on tests to measure intelligence, short-term memory and word recall, according to research at the Finnish Institute of Occupational Health. They tracked 2,214 British civil servants who signed up to a long-term health study in the mid-1980s. In the years since, volunteers have undergone a succession of tests to measure their wellbeing.

Two points:

  1. Probably fake. Civil Servants don’t work those hours.
  2. If the reduced performance is better than 40/55 of the 40 hour week, then you are ahead.
