CHANGES IN COMPOSITION OF SWEAT DURING ACCLIMATIZATION TO HEAT

Abstract

The properties of sweat depend on acclimatization, the rate of sweating, inherent characteristics of the individual, and probably other factors. It becomes more dilute with adaptation to hot atmospheres. Its inorganic constituents increase in conc. as sweating becomes more profuse; at the same time, nitrogen excretion diminishes. The susceptibility of some individuals to heat cramps no doubt depends in part on the inability of their sweat glands to reduce NaCl loss to a low level.
