You often overtime? Should begin to be more careful. The reason, recent research reveals that working more than eight hours a day it could increase the risk of heart disease by 80 percent.
The researchers said that long hours can charge thousands of employees to be exposed to the risk of heart attack and stroke. The warning comes following an analysis of 12 past studies since 1958, involving a total of 22,000 people from around the world.
Analysis, by scientists at the Finnish Institute of Occupational Health, found that those who work longer than eight hours per day had a 40-80 percent chance of developing heart disease.
This increase in the size of which varies depending on how each study was conducted. Rate effect is more pronounced when participants were asked how long they work. When researchers monitored the hours of work, increased risk of heart disease were 40 percent.
Principal investigator said the effect could be due to "prolonged labor and exposed to stress." Other triggers could be poor eating habits and lack of exercise due to limited time.
Middle-aged workers who have working hours for 55 hours or more a week had poorer brain function than those who work less than 40 hours. Not only that, they also had lower scores on tests to measure intelligence, short-term memory and word recall.
In the UK, employees are known to have the longest working hours in Europe, with full-time employees an average of 42.7 hours per week. In Germany typically work for 42 hours, while Denmark worked for 39.1 hours.
It is estimated that more than 5 million people in the UK each year have to work extra hours in order to survive in their work. However, according to the latest research states that if done in the long term could endanger the health of workers.
"There are several potential mechanisms that may underlie the association between long working hours and heart disease," he said.
Besides exposed to psychological stress, he added that the other can trigger increased levels of the stress hormone cortisol.
