Working for nine hours a day, women may have a higher risk of depression, but not men find a study.
Women with over 55 hours of work per week, a week-long symptom of 35-40 hours of work per week had a depression of 7.3 percent.
However, men did not find the case, he found the exam.
"This is an observational study. Even though we do not specify causes, many women face extra burdens that make men work harder than men, long hours of work, high time pressure and serious responsibilities." said researcher Gill Weston, a postdoctoral student at University College London.
"In addition, women who work for most weekends concentrate on jobs in the wage-labor sector, with higher levels of depression," said Weston.
For the research published in the Epidemiology and Community Health Bulletin, 11,215 workers and 12,188 women were employed.
The study also showed that on weekends, normal depression was greater among men (3.4%) and women (4.6%).
Two-thirds of men worked at weekends with half of women. Those who have worked on the whole weekend or during the weekends are likely to have very little jobs and have less and happier jobs than those who did not work at weekends or weekends.
"Our findings, responsible for employers and politicians, think about adding support for women's clothing, reducing labor costs and long hours or irregularities," said Weston.
"The most beneficial practice can have jobs between both workers and two sexes," he suggested.
