The intervention will take place after lunch for about 2-3 hours in regular working conditions. Group A will be fitted with a cooling and bio-harness. At the end of each workday, participants will return the monitors and vests will be removed and returned to the research station. The biomonitor's battery will be recharged and data downloaded. The ice vests will be placed in a freezer.
