Abstract:

Experiments were undertaken to clarify the effects of heat acclimatization on the sodium concentration of sweat and to distinguish these from the effects of concomitant changes in sweat rate. Sweat samples were collected at different rates of sweating from three unacclimatized subjects, using a Perspex capsule containing filter papers. The subjects were then acclimatized to heat, using a passive hyperthermia technique, and a further series of sweat samples obtained at different rates of sweating. The weighed samples were analyzed for sodium concentration and the results used to plot sodium concentration against sweat rate before and after acclimatization. The results show significant reduction in sweat sodium concentration with acclimatization over a wide range of sweat rates. Possible mechanisms are discussed. Author
