Work bred, but if it is too much, according to scientists on organisms harmful effects, especially after forty. If at this age are working more than 25 hours per week, significantly drops in your cognitive performance – will begin to fade memory, ability to think and begin to suffer mentally. At least so says a study in which a team of Australian and Japanese scientists, with the results published by the Institute of Applied Economic and Social Research in Melbourne.
Researchers examined the cognitive abilities of more than 6,500 Australians aged over forty years, and compared the results of these tests with the number of hours that these people worked for a week. Their analysis showed that there is a complex relationship between work and intelligence: if research participants worked fewer than 25 hours a week, then obviously their work has led to an increase in mental capacity, but once you work more than 25 hours a week, occurred quickly reversed the situation.
“The work seemed initially stimulates brain cells. At a certain stage but comes into play stress associated with physical and mental work and the favorable impact of work to combat begins. Too much work in terms of cognitive function is worse than not working at all, “he quoted by Italian daily Corriere della Sera Colin McKenzie from Japan’s Keio University.
Scientists do not yet analyzed the only relationship that exists between the number of hours worked per week and cognitive performance, and did not determine what the cause of the observed results. The study authors have put forward two hypotheses: is stress and lack of sleep. These factors can profoundly influence the structure and capacity of our brain.
The effects work for persons under forty years of age may be less obvious. “I conclude that the recovery capability of the brain in younger people is different,” says McKenzie. “Young people tend to be more resistant to the effects of long shifts,” he adds. People over forty years are at such a stage of life, which often have to care for young children or elderly parents. This gives them the social role of fundamental importance and effects of intensive work on their brains are more complex.
The ideal part-time job
In connection with the increasing age of retirement worldwide study results suggest that we work more and longer, it does not increase our productivity. Quite the contrary: three days of work a week (25 hours) or part-time work seems to be a productive option for those who are in their forties.
While in Italy it sounds like heresy, for Sweden it is rather a confirmation of a new trend: the various enterprises and institutions of the Scandinavian countries are experimenting with the introduction of a six-hour work shifts as standard. Higher productivity of employees could justify maintaining the same wage for the situation where the working ten hours per week less. The results so far seem to confirm this hypothesis.
