Abstract The objective of the study was to investigate the physiological responses of construction workers under thermally stressful environments in the United Arab Emirates using Thermal Work Limit (TWL) as a method of environmental risk assessment. Body temperature, fluid intake and urine specific gravity were recorded, and continuous heart rate monitoring was used to assess fatigue. Subjects were monitored over three consecutive shifts. TWL and WBGT were used to assess the thermal stress. The results indicated that the workers were not physiologically challenged despite fluctuating harsh environmental conditions. Core body temperatures were not elevated suggesting satisfactory thermoregulation. The data demonstrate that people can work, without adverse physiological effects in hot conditions if they are provided with the appropriate fluids and are allowed to self-pace.
