Abstract This study aimed to quantify likely sodium losses during work in heat. Male subjects exercised in an environmental chamber on two consecutive days in both winter and summer. Sweat collecting devices were attached to the upper arms and legs. Sweat rates were higher and sodium concentrations were lower in the summer than the winter trials. Sweat sodium concentration was reduced on the second day in summer but not in winter. The data predict average losses over a work shift of 10-15g of sodium chloride. Implications of these findings are discussed.
