Those who have lost their jobs can take solace in the fact that although working may put food on the table, it can also break your brain. A study has found that busy bees who labor more than 55 hours a week develop problems with reasoning, memory and vocabulary, and the problems get worse the more they work.
Lead researcher Dr Marianna Virtanen, from the Finnish Institute of Occupational Health, said: “The disadvantages of overtime work should be taken seriously.”
It is not known why working long hours might have an adverse effect on the brain.
However, the researchers say key factors could include increased sleeping problems, depression, an unhealthy lifestyle and a raised risk of cardiovascular disease, possibly linked to stress.
