Abstract
Summary The effects of dehydration prior to heat exposure on sweating and body temperature were tested in 8 men and 8 women, dehydration being 1.3 and 1.0% of body weight, respectively. The subjects were exposed to 40° C for 60 min. Compared with controls (C), in the dehydrated men (D) there was a longer delay in the onset of sweating (C, 7.8, D, 11.6 min,p-2 · h−1,p< 0.001), and a greater increase in Tre (C, 0.31, D, 0.43° C,ppr=0.81,pr=0.83,p<0.01). It is concluded that dehydration affects sweating and body temperature in men more severely than in women.Keywords
