title: Effect of tap-water iontophoresis on sweat gland recruitment, skin temperature and skin blood flow.
abstract: Our interest was to quantify the role of sweat gland activation on the maintenance of skin temperature during mild exercise in the heat. Seven days of tap-water iontophoresis decreased the number of active sweat glands by 72% which significantly increased forearm skin temperature and blood flow during mild exercise (70 W) in the heat (32 degrees C). Skin temperature of the treated forearm was 0.5 degrees C warmer (P=0.049); skin blood flow in the treated forearm was 13% higher than the control arm (P=0.021). These results illustrate the importance of sweat evaporation on skin temperature and blood flow during exercise.
