Comparison of physiological responses to heat between subtropical and temperate natives.

Adaptive Changes in Physiological Responses of Men to Heat Induced by Heat Acclimatization and Physical Training.

“…These findings were in agreement with the results reported by many investigators (Ohara 1966;Ihzuka et al, 1986) . A decrease in salt concentration of sweat increases the difference in vapor pressure between the sweat on the skin and the surrounding air (Hori et al, 1982) . It may thus be considered that the smaller rise in rectal temperature during exercise in summer was caused by a greater heat dissipation due to profuse sweating with lower Na concentration as well as the physical characteristics favorable to heat dissipation.…”
