U.S., Sept. 30 -- ClinicalTrials.gov registry received information related to the study (NCT07847437) titled 'Progressive Heat Exposure and Physiological Strain' on Sept. 18.
Brief Summary: Occupational heat-stress guidelines are commonly based on the level of environmental heat exposure and are largely derived from studies conducted under constant environmental conditions. However, outdoor workers are typically exposed to dynamic conditions, with environmental heat often increasing progressively from morning to afternoon. Consequently, workers may experience substantially different patterns of heat exposure across the workday even when average daily heat exposure is equivalent. It remains unclear whether the temporal pattern of heat expos...
