Research conducted on 2,000 employees in the UK for nearly six years has shown new evidence that too many jobs have negative effects on mental health.
An article published in the journal PLoS One stated, 'the individuals who work for 11 hours or more per day will double the risk of suffering from depression.
"Although sometimes working overtime to have benefits for individuals and society, but it is important to understand the link between excessive working hours with an increased risk of major depression," said Dr. Marianna Virtanen from the Finnish Institute of Occupational Health.
The study showed that a person's inability to manage time for work and family care will extend the increased levels of stress hormones.
The investigation also showed that long working primarily work the night shift is associated with cardiovascular disease, cancer, family problems and mental disorders.
World Health Organization (WHO) predicts that in 2030 the number of individuals affected by the global depression syndrome would became higher than other health problems.
This condition is even more common in developing countries, but not a few rich countries have more complex problems.
