A group of scientists from Japan and Austria, the study determined how many should continue the optimal productivity of the working week. It turned out that the human brain can normally only work 30 hours a week. Further, its activity is sharply reduced.
The experiment involved 3 thousands of men and 3.5 thousand women. The volunteers were asked to perform a few tests that determine the rate and quality of perception.
Scientists have proven that when you work more than 30 hours a week greatly reduced the indicators of intellectual activity. Moreover, with 50-60 hour work week performance dropped to critical values. In addition to this accumulated fatigue.
According to the findings of the study, women need to work from 22 to 27 hours, men from 25 to 30 hours per week. This information is more focused on employees over the age of 40 years. Young people usually have to work some more.
