A study conducted by the World Health Organisation and the International Labour Organisation recently found that the long working hours kills hundreds of people every year.
The study has included 22 studies on stokes and 37 studies on ischemic heart diseases.
Also, it collected data from more than 2,300 surveys in 194 countries.
Working 55 hours a week increases risks of strokes by 35% and increased the risk of ischemic heart disease by 17%.
