Scanning analysis revealed that those who are “over -employed ,, especially in the frontal lobe, have an important role in various cognitive functions, an average increase in an average increase in the volume of the left caudal mid -frontal gypsies. Attention is included in the study memory and language -related processing.
The scans also increased volume in the 17 regions of the brain, including insulaa, which has an important role in understanding a person’s own awareness and social context in the integration of parts and sensory and motor functions responsible for attention, planning and decision -making.
The researchers said: “Extremely working individuals have made significant changes in brain regions associated with managers’ function and emotional regulation.”
However, it is not possible to determine whether these structural changes were caused by long hours of work, or that they did not give individuals a predisposition to work longer hours.
In addition, those who took long working hours each week were significantly younger, they had less time, and they were higher than those who block the standard hours.
Excessive work ‘800,000 kills a year’
Working regularly for long weeks has previously been linked to heart attack, stroke and increase in mental health problems.
The effect of the stress of excessive processing increases cortisol production, increases blood pressure and weakens the immune system.
Other studies have found that excessive work and stress can lead to sleep, depression, heavy drinking, bad memory and heart disease.

Researchers estimate that the International Labor Organization has killed more than 800,000 people a year.
The research team concluded that the study provides “preliminary evidence that excessive work is associated with structural brain changes in cognitive and emotion regions”.
“These findings emphasize the need for more research to understand the long -term cognitive and emotional consequences of extreme work by providing new neurobiological evidence that connects long -term working hours to structural brain changes.
“The results emphasize the importance of handling excessive work as an occupational health concern and emphasize the need for workplace policies that reduce excessive working hours.”
The maximum of 48 hours of legal for a working week in the UK is 48 hours.

Ruth Wilkinson, Head of Policy and Public Relations at the Occupational Health and Security Assistance Authority, said that almost one quarter of the British regularly worked more than that.
“Global analysis from the World Health Organization and the International Labor Organization found that the work of long hours was an increase and that the total estimated work burden was responsible for about one -third,” he said.
“Today, what we define as the ‘small edition of working life’ can be experienced in a long hour of culture.”
He said that a Yougov questionnaire is part of the workplace of the workplace beyond the contracted hours of 44 percent of employees, and that more than half of the work “working E -mails and messages regularly outside the working hours”.
