Weekly long can compromise the brain function.
Excess of stress hormones may explain the problem.

Working many hours per week has harmful effects on immune systems, cardiovascular and digestive tract. Patterns of sleep and rest are modified and changes in behavior may occur with aggressive manifestations. The study evaluated more than 2 thousand employees on two occasions in 1997 and 2004 for comparison.

The work focused on people over 50 years and sought to understand the correlations between shift work and the functioning brain. Participants were evaluated with tests of language, logical thinking, reasoning and memory. The results showed that those who worked more than 55 hours per week had worse results in initial tests.

The development of these workers was also lower when compared to those who worked 40 hours or less per week, with a greater decline in brain function. Not to exist factors that could influence the results, several issues were taken into account, as worker's health status, smoking, alcohol use and physical exercise. None of them changed significantly compared data.

The scientists' explanation for this decrease in capacity may be related to changes in the levels of neuroendocrine markers of stress. The findings of this research can help doctors understand how to handle the changes of aging and what measures can be taken to protect the brain.
