“Agricultural workers are at heightened risk of exertional heat stress when manual outdoor work such as land preparation, planting, weeding and harvesting is required during periods of high


ambient heat loads. To defend against hyperthermia, workers slow down to reduce metabolic heat production and the associated rise in body temperature,” said the research led by Gerald C


Nelson, from the University of Illinois, US.
