Socially disadvantaged people are disproportionately affected by temperature extremes. A recent study explored this point in Cambodia: one of the world's hottest and most humid countries. It evidenced the extent of the heat exposure faced by workers in Cambodia and the way occupational, environmental and geographical dynamics combine to shape it. The study’s lead author, Dr Laurie Parsons of Royal Holloway, University of London, contextualises this for the country’s garment workers.
