The maximum number of hours per week that the average person can devote to work without risk to health, is 39 hours. Exceeding this level may not be safe for both the physical and psychological state of the employee, say experts from the Australian National University. That is the conclusion, scientists have come to the end of the study with the participation of 8000 people.
It may be noted that even the "standard" eight-hour day means one hour of work per week exceed the amount recommended by scientists highs and very common in the world (and, in particular, in Australia) is a nine-hour working day for a five-day working week makes exceeded the "limit "very noticeable.
Experts note that in particular, the "extra" office hours are undesirable for women. The fact that they often do not do much more paid and, in some way, do not "have regard to" work around the house, also consuming a lot of energy. In view of this fact, scientists say that the "average" indicator in 39 hours, in fact, for women the figure is 34 hours, but not too active in domestic work of men - 47 hours.
The study is published in the journal Social Science & Medicine.
Last year, another group of experts representing the Melbourne Institute, concluded that the optimal duration of the working week for those over 40 years old can be up to 25 hours, distributed between the three working days. According to the study the scientists, it is the number of hours allowed to simultaneously hold the human brain "in good shape" and does not lead to its exhaustion. People who worked 25 hours a week, showed the best results in passing on intelligence tests.
