Persistence of Impaired Heat Tolerance from Artifically Induced Miliaria Rubra,
Abstract
Acclimatization to heat was conducted in these subjects to provide a reasonably equivalent experimental baseline from which to conduct the study. Heat acclimatization has been found by some to result in a reduction in sweat chloride provoked primarily by a salt deficit, while the chloride concentration is found to be greatly increased in the sweat from areas involving miliaria. These incongruous findings may point out the over importance placed on increased chloride concentration in the pathophysiology associated with miliaria particularly as it affects performance. Nevertheless, since acclimatized, the individuals are better able to maintain fluid balance than those not acclimatized, the importance of the reduced tolerance times of these experimental subjects is further magnified. The findings from this investigation clearly illustrate that one severe bout of laboratory-induced miliaria rubra results in a marked reduction in performance and an increase in several physiological responses of these individuals compared to matched controls. Had the humidity been elevated to that of jungle conditions, it is quite possible that the results would have been even more dramatic. The distribution of sweat glands differs in various areas of the body. The effect of heat rash on different areas of the body and associated work-heat the body. The effect of heat rash on different areas of the body and associated work-heat performance responses is not known.
