Working long hours is killing hundreds of thousands of people a year in a worsening trend that may accelerate further due to the COVID-19 pandemic, the World Health Organization said on Monday. Reuters reports that overall, the study – drawing on data from 194 countries – said that working 55 hours or more a week is associated with a 35% higher risk of stroke and a 17% higher risk of dying from ischemic heart disease compared with a 35-40 hour working week. It also showed that people living in Southeast Asia and the Western Pacific region — a WHO-defined region which includes China, Japan and Australia — were the most affected.
