Sweating distribution and active sweat glands on the scalp of young males in hot-dry and hot-humid environments

We investigated the effects of humidity on regional sweating secretion and active sweat gland density on the scalp during passive heating in hot environments. Eight male subjects shaved their heads prior to expose to dry (30%RH; H30%) and humid (85%RH; H85%) conditions at an air temperature of 32 °C. Total sweat rate, local sweat rates (frontal, vertex, temporal, and occipital regions), active sweat glands on the scalp (2 frontal, 2 parietal, 2...
